&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, private keys never need to touch potentially-vulnerable software&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;
&lt;br /&gt;
== Connecting to a full node ==&lt;br /&gt;
&lt;br /&gt;
By default, most hardware wallets instruct the user to connect to the manufacturer&#039;s own web interface. The web page cannot steal the user&#039;s private keys but can spy on them or trick them into accept fake payments.&lt;br /&gt;
&lt;br /&gt;
Hardware wallets only keep the [[private keys]] safe and create spending transactions; they cannot tell you if you have actually received coins and in what quantity. Bitcoin&#039;s security model also requires that [[full node]] wallets are used. If not, somebody could pay you with a transaction of something other than bitcoin. If bitcoin is digital gold then a full node wallet is your own personal goldsmith who checks that the incoming payments are actually real. Also the third-party wallet will see all your [[Address|bitcoin addresses]] so this is very damaging to your privacy.&lt;br /&gt;
&lt;br /&gt;
Most hardware wallets can be connected to [[Electrum]] bitcoin wallet. Electrum can be connected to your own [[Electrum#Electrum Personal Server|full node via a server]]. &lt;br /&gt;
&lt;br /&gt;

== Commercial hardware wallets (ordered chronologically) ==&lt;br /&gt;
&lt;br /&gt;
=== [[Trezor|Trezor One]] ===&lt;br /&gt;
[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with Trezor]]&lt;br /&gt;
&lt;br /&gt;
[[Trezor]] is a secure bitcoin storage and a transaction signing tool with open source hardware and software. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case Trezor gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
Trezor also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;
&lt;br /&gt;
Trezor One offers everything needed to protect cryptocurrency funds together with advanced features like [https://wiki.trezor.io/User_manual:Password_Manager Password manager]  or [https://wiki.trezor.io/User_manual:Two-factor_Authentication_with_U2F U2F two-factor authorization]. &lt;br /&gt;

[[File:keepkey.jpg|300px|thumb|left|KeepKey showing a bitcoin transaction that needs to be manually approved.]]&lt;br /&gt;
&lt;br /&gt;
KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper backups. &lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;

=== Ledger Nano - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:ledger_wallet_photo.jpg|300px|thumb|left|Ledger Wallet USB]]&lt;br /&gt;
&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, private keys never need to touch potentially-vulnerable software&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;
&lt;br /&gt;
== Connecting to a full node ==&lt;br /&gt;
&lt;br /&gt;
By default, most hardware wallets instruct the user to connect to the manufacturer&#039;s own web interface. The web page cannot steal the user&#039;s private keys but can spy on them or trick them into accept fake payments.&lt;br /&gt;
&lt;br /&gt;
Hardware wallets only keep the [[private keys]] safe and create spending transactions; they cannot tell you if you have actually received coins and in what quantity. Bitcoin&#039;s security model also requires that [[full node]] wallets are used. If not, somebody could pay you with a transaction of something other than bitcoin. If bitcoin is digital gold then a full node wallet is your own personal goldsmith who checks that the incoming payments are actually real. Also the third-party wallet will see all your [[Address|bitcoin addresses]] so this is very damaging to your privacy.&lt;br /&gt;
&lt;br /&gt;
Most hardware wallets can be connected to [[Electrum]] bitcoin wallet. Electrum can be connected to your own [[Electrum#Electrum Personal Server|full node via a server]]. &lt;br /&gt;

[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with Trezor]]&lt;br /&gt;
&lt;br /&gt;
[[Trezor]] is a secure bitcoin storage and a transaction signing tool with open source hardware and software. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case Trezor gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
Trezor also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;
&lt;br /&gt;
Trezor One offers everything needed to protect cryptocurrency funds together with advanced features like [https://wiki.trezor.io/User_manual:Password_Manager Password manager]  or [https://wiki.trezor.io/User_manual:Two-factor_Authentication_with_U2F U2F two-factor authorization]. &lt;br /&gt;

[[File:keepkey.jpg|300px|thumb|left|KeepKey showing a bitcoin transaction that needs to be manually approved.]]&lt;br /&gt;
&lt;br /&gt;
KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper backups. &lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;

[[File:ledger_wallet_photo.jpg|300px|thumb|left|Ledger Wallet USB]]&lt;br /&gt;
&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

BWALLET is a clone of Trezor by a Chinese company.&lt;br /&gt;
Trezor code is open source and this device operates like a Trezor.&lt;br /&gt;
However, this product has been [https://www.reddit.com/r/Bitcoin/comments/2tyier/bwallet_review_by_trezor_developer/ reviewed by Marek aka Slush(Trezor developer)] and he has found some problems which makes this device less than 100% compatible, for example it doesn&#039;t work with [http://mytrezor.com myTREZOR.com] website and it does not work with Trezor official firmware. &lt;br /&gt;

&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, private keys never need to touch potentially-vulnerable software&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;
&lt;br /&gt;
== Connecting to a full node ==&lt;br /&gt;
&lt;br /&gt;
By default, most hardware wallets instruct the user to connect to the manufacturer&#039;s own web interface. The web page cannot steal the user&#039;s private keys but can spy on them or trick them into accept fake payments.&lt;br /&gt;
&lt;br /&gt;
Hardware wallets only keep the [[private keys]] safe and create spending transactions; they cannot tell you if you have actually received coins and in what quantity. Bitcoin&#039;s security model also requires that [[full node]] wallets are used. If not, somebody could pay you with a transaction of something other than bitcoin. If bitcoin is digital gold then a full node wallet is your own personal goldsmith who checks that the incoming payments are actually real. Also the third-party wallet will see all your [[Address|bitcoin addresses]] so this is very damaging to your privacy.&lt;br /&gt;
&lt;br /&gt;
Most hardware wallets can be connected to [[Electrum]] bitcoin wallet. Electrum can be connected to your own [[Electrum#Electrum Personal Server|full node via a server]]. &lt;br /&gt;
&lt;br /&gt;

=== [[Trezor|Trezor One]] ===&lt;br /&gt;
[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with Trezor]]&lt;br /&gt;
&lt;br /&gt;
[[Trezor]] is a secure bitcoin storage and a transaction signing tool with open source hardware and software. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case Trezor gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
Trezor also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;
&lt;br /&gt;
Trezor One offers everything needed to protect cryptocurrency funds together with advanced features like [https://wiki.trezor.io/User_manual:Password_Manager Password manager]  or [https://wiki.trezor.io/User_manual:Two-factor_Authentication_with_U2F U2F two-factor authorization]. &lt;br /&gt;

[[File:keepkey.jpg|300px|thumb|left|KeepKey showing a bitcoin transaction that needs to be manually approved.]]&lt;br /&gt;
&lt;br /&gt;
KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper backups. &lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;

&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, private keys never need to touch potentially-vulnerable software&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;
&lt;br /&gt;
== Connecting to a full node ==&lt;br /&gt;
&lt;br /&gt;
By default, most hardware wallets instruct the user to connect to the manufacturer&#039;s own web interface. The web page cannot steal the user&#039;s private keys but can spy on them or trick them into accept fake payments.&lt;br /&gt;
&lt;br /&gt;
Hardware wallets only keep the [[private keys]] safe and create spending transactions; they cannot tell you if you have actually received coins and in what quantity. Bitcoin&#039;s security model also requires that [[full node]] wallets are used. If not, somebody could pay you with a transaction of something other than bitcoin. If bitcoin is digital gold then a full node wallet is your own personal goldsmith who checks that the incoming payments are actually real. Also the third-party wallet will see all your [[Address|bitcoin addresses]] so this is very damaging to your privacy.&lt;br /&gt;
&lt;br /&gt;
Most hardware wallets can be connected to [[Electrum]] bitcoin wallet. Electrum can be connected to your own [[Electrum#Electrum Personal Server|full node via a server]]. &lt;br /&gt;
&lt;br /&gt;

=== [[Trezor|Trezor One]] ===&lt;br /&gt;
[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with Trezor]]&lt;br /&gt;
&lt;br /&gt;
[[Trezor]] is a secure bitcoin storage and a transaction signing tool with open source hardware and software. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case Trezor gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
Trezor also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;
&lt;br /&gt;
Trezor One offers everything needed to protect cryptocurrency funds together with advanced features like [https://wiki.trezor.io/User_manual:Password_Manager Password manager]  or [https://wiki.trezor.io/User_manual:Two-factor_Authentication_with_U2F U2F two-factor authorization]. &lt;br /&gt;

[[File:keepkey.jpg|300px|thumb|left|KeepKey showing a bitcoin transaction that needs to be manually approved.]]&lt;br /&gt;
&lt;br /&gt;
KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper backups. &lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;

&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, private keys never need to touch potentially-vulnerable software&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;
&lt;br /&gt;
== Connecting to a full node ==&lt;br /&gt;
&lt;br /&gt;
By default, most hardware wallets instruct the user to connect to the manufacturer&#039;s own web interface. The web page cannot steal the user&#039;s private keys but can spy on them or trick them into accept fake payments.&lt;br /&gt;
&lt;br /&gt;
Hardware wallets only keep the [[private keys]] safe and create spending transactions; they cannot tell you if you have actually received coins and in what quantity. Bitcoin&#039;s security model also requires that [[full node]] wallets are used. If not, somebody could pay you with a transaction of something other than bitcoin. If bitcoin is digital gold then a full node wallet is your own personal goldsmith who checks that the incoming payments are actually real. Also the third-party wallet will see all your [[Address|bitcoin addresses]] so this is very damaging to your privacy.&lt;br /&gt;
&lt;br /&gt;
Most hardware wallets can be connected to [[Electrum]] bitcoin wallet. Electrum can be connected to your own [[Electrum#Electrum Personal Server|full node via a server]]. &lt;br /&gt;
&lt;br /&gt;

=== [[Trezor|Trezor One]] ===&lt;br /&gt;
[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with Trezor]]&lt;br /&gt;
&lt;br /&gt;
[[Trezor]] is a secure bitcoin storage and a transaction signing tool. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case Trezor gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
Trezor also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;
&lt;br /&gt;
Trezor One offers everything needed to protect cryptocurrency funds together with advanced features like [https://wiki.trezor.io/User_manual:Password_Manager Password manager]  or [https://wiki.trezor.io/User_manual:Two-factor_Authentication_with_U2F U2F two-factor authorization]. &lt;br /&gt;

KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper backups. &lt;br /&gt;

At present it is the only bitcoin hardware wallet you can buy that works with iPhone. The device weighs one ounce and is the size of a credit card 4 mm thick.&lt;br /&gt;
 &lt;br /&gt;
Bitlox allows you to set up hidden wallets. Unlike other hardware wallets your seed is never displayed on a connected computer or phone but only on the Bitlox. All your wallet, device and transaction PINs are only entered on the BitLox and never on any app. &lt;br /&gt;
&lt;br /&gt;
BitLox has also implemented several advanced security features not available on any other bitcoin hardware wallet. &lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;
&lt;br /&gt;

=== Ledger Nano - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:ledger_wallet_photo.jpg|300px|thumb|left|Ledger Wallet USB]]&lt;br /&gt;
&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

Ideally wallets and services would first support &#039;&#039;sending to&#039;&#039; bech32 addresses. After almost everything can send to, then people may be willing to adopt bech32 widely for receiving.&lt;br /&gt;

&lt;br /&gt;
Some blockchain explorers can only parse the bech32 address and display it, they don&#039;t build an index so users cannot search for bech32 addresses.&lt;br /&gt;

&lt;div&gt;[[Bech32]] is a new bitcoin [[address]] format specified by [[BIP 0173]]. This page tracks the adoption of [[Bech32]].&lt;br /&gt;
&lt;br /&gt;
Ideally wallets and services would first support &#039;&#039;sending to&#039;&#039; bech32 addresses. After almost everything can send to, then people may be willing to adopt bech32 widely for receiving.&lt;br /&gt;
&lt;br /&gt;
The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1&lt;br /&gt;

And addresses &amp;lt;code&amp;gt;bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq&amp;lt;/code&amp;gt; and &amp;lt;code&amp;gt;bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9&amp;lt;/code&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Some blockchain explorers can only parse the bech32 address and display it, they don&#039;t build an index so users cannot search for bech32 addresses.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;hardware wallet&#039;&#039;&#039; is a special type of [[wallet|bitcoin wallet]] which stores the user&#039;s private keys in a secure hardware device.&lt;br /&gt;
&lt;br /&gt;
They have major advantages over standard software wallets:&lt;br /&gt;
&lt;br /&gt;
* private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext&lt;br /&gt;
* immune to computer viruses that steal from software wallets&lt;br /&gt;
* can be used securely and interactively, as opposed to a [[paper wallet]] which must be imported to software at some point&lt;br /&gt;
* much of the time, the software is open source, allowing a user to validate the entire operation of the device&lt;br /&gt;
&lt;br /&gt;
This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.&lt;br /&gt;
&lt;br /&gt;
== Security risks ==&lt;br /&gt;
&lt;br /&gt;
To date there have been no verifiable incidents of Bitcoins stolen from hardware wallets. Hardware wallets are relatively new, but at least for the time being they have maintained a good track record, unlike the numerous incidents of Bitcoin theft from Internet-connected computers.&lt;br /&gt;
&lt;br /&gt;
However, it&#039;s important to understand that hardware wallets are a high value target and depend on various assumptions holding true to maintain security. They are not a silver bullet, and there are several realistic ways in which a hardware wallet can fail to protect your Bitcoin. These risks need to be carefully considered when deciding how much trust to place in a hardware wallet, and which hardware wallet to buy.&lt;br /&gt;
&lt;br /&gt;
How a hardware wallet could fail to protect your Bitcoin:&lt;br /&gt;
&lt;br /&gt;
# &#039;&#039;&#039;Malware swaps recipient Bitcoin addresses&#039;&#039;&#039;: a hardware wallet won&#039;t protect you from being tricked into sending Bitcoin to the wrong address. For example, malware on a PC could monitor for high value transactions and then swap out the recipient&#039;s authentic Bitcoin address for an address controlled by the attacker. When the stakes are high, multi factor (e.g., over the phone) confirmation of a recipient&#039;s Bitcoin address is recommended.&lt;br /&gt;
# &#039;&#039;&#039;Insecure RNG ([https://en.wikipedia.org/wiki/Random_number_generation Random Number Generator])&#039;&#039;&#039;: hardware wallets rely on the security of an RNG, often embedded in hardware, to generate your wallet&#039;s private keys securely. Unfortunately, it is notoriously difficult to verify the true randomness of the RNG. An insecure RNG may create wallet keys that can later be recreated by an attacker, by generating psuedo-randomness that would seem statistically indistinguishable from true randomness yet still be predictable to an advanced attacker. An RNG may become insecure as a result of malicious weakening or an unintentional mistake. This failure mode is common to any wallet generation procedure in which the true randomness of the source of entropy being used can not be verified.&lt;br /&gt;
# &#039;&#039;&#039;Imperfect implementation&#039;&#039;&#039;: the security of all computing devices relies on the quality of their implementation. Hardware wallets are no exception. Bugs at the software, firmware or hardware level may allow attackers to break into a hardware wallet and gain unauthorized access to secrets. Even if the design is perfect, proving the security of a hardware or software implementation is a very hard, mostly unsolved problem. To date, no wallet in existence is implemented using provably correct software.&lt;br /&gt;
# &#039;&#039;&#039;Compromised production process&#039;&#039;&#039;: even a perfect software and hardware implementation of a hardware wallet would be vulnerable to a corrupt production process that introduces intentional or unintentional holes into the final product. The introduction of hardware backdoors is a [https://www.wired.com/2016/06/demonically-clever-backdoor-hides-inside-computer-chip/ real concern] for high risk financial and military applications.&lt;br /&gt;
# &#039;&#039;&#039;Compromised shipping process&#039;&#039;&#039;: a compromised fulfillment process may substitute or modify secure devices for superficially identical but insecure replacements. Government programs that intercept hardware and modify them in route to insert backdoors [https://arstechnica.com/.../photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ are known to exist].&lt;br /&gt;
&lt;br /&gt;
In summary:&lt;br /&gt;
&lt;br /&gt;
* While not a silver bullet hardware wallets can still be extremely useful, assuming you take care to use a good one: an authentic device manufactured by trustworthy, technically competent security experts with a good reputation (e.g., [[TREZOR]]).&lt;br /&gt;
&lt;br /&gt;
* [[Cold storage]] solutions implemented with open source software and general purpose hardware (e.g., [[BitKey]], Pi Wallet), using a verifiable source of entropy such as physical dice may provide superior security for some use cases (e.g., long term savings).&lt;br /&gt;

&lt;br /&gt;

=== [[TREZOR]] The Bitcoin Safe ===&lt;br /&gt;
[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with TREZOR]]&lt;br /&gt;
&lt;br /&gt;
[[TREZOR]] is a secure bitcoin storage and a transaction signing tool. The private keys are generated by the device and never leave it thus they cannot be accessed by a malware.&lt;br /&gt;
&lt;br /&gt;
It uses a deterministic wallet structure which means it can hold an unlimited number of keys ([[BIP 0032]]/[[BIP 0044]]). A recovery seed is generated when the device is initialized. In case TREZOR gets lost or stolen, all its contents can be recovered using this seed (private keys, bitcoin balance and transaction history) into a new device or another [[BIP 0039]]/[[BIP 0044]] compatible wallet. &lt;br /&gt;
&lt;br /&gt;
TREZOR also introduced a unique way of PIN entering preventing keyloggers from recording it even when entered on a compromised computer. An encryption passphrase can be set on top of the PIN protection. More passphrases can be used for plausible deniability.&lt;br /&gt;

=== Ledger HW.1 - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]&lt;br /&gt;
&lt;br /&gt;
HW.1 is an implementation of a deterministic ([[BIP 0032]]) Hardware Wallet on a USB smartcard.&lt;br /&gt;
&lt;br /&gt;
It is typically used as a blind secure device for multi signature transactions - holding a set of derived private keys and signing transactions without requiring user confirmation.&lt;br /&gt;
&lt;br /&gt;
Power users can rely on it to confirm all transactions with a second factor scheme turning the dongle into a keyboard typing what the user is supposed to have signed, as a protection against malware.&lt;br /&gt;
&lt;br /&gt;
It is also possible to customize HW.1 for more specific needs, such as creating a prepaid card without revealing the deterministic seed before it is received by the user, or securing bitcoin transactions on a server.&lt;br /&gt;

=== Ledger Nano - USB Smartcard Hardware Wallet  ===&lt;br /&gt;
[[File:ledger_wallet_photo.jpg|300px|thumb|left|Ledger Wallet USB]]&lt;br /&gt;
&lt;br /&gt;
Ledger Nano protects your Bitcoin data within a smartcard. Its micro-processor certified against all types of attacks (both physical and logical), and has been used in the banking industry for decades (think credit card chips). The device connects to your computer through the USB port and will do all the Bitcoin cryptographic heavy lifting such as signing transactions inside its secure environment. You can therefore use your Bitcoin account with maximum trust, even on an insecure or compromised computer.&lt;br /&gt;
&lt;br /&gt;
The second factor verification of the transaction signature can be done either with a paired smartphone (Android, iOS) or a physical security card.&lt;br /&gt;
&lt;br /&gt;
The Ledger Wallet Chrome application (available also on Chromium) provides an easy onboarding as well as a seamless user experience, and the Nano is compatible with numerous third party software: [[Electrum]], [[Mycelium]], [[GreenAddress]], Greenbits, [[Coinkite]] and Copay.&lt;br /&gt;

Trezor code is open source and this device operates like a Trezor.&lt;br /&gt;
However, this product has been [https://www.reddit.com/r/Bitcoin/comments/2tyier/bwallet_review_by_trezor_developer/ reviewed by Merek aka Slush(Trezor developer)] and he has found some problems which makes this device less than 100% compatible, for example it doesn&#039;t work with [http://mytrezor.com myTREZOR.com] website and it does not work with Trezor official firmware. &lt;br /&gt;

[[File:keepkey.jpg|300px|thumb|left|KeepKey showing a bitcoin transaction that needs to be manually approved.]]&lt;br /&gt;
&lt;br /&gt;
KeepKey is a USB device that stores and secures your bitcoins. When you entrust KeepKey with your money, each and every bitcoin transaction you make must be reviewed and approved via it&#039;s OLED display and confirmation button.&lt;br /&gt;
&lt;br /&gt;
KeepKey has a unique recovery feature utilizing a rotating cipher to restore private keys with a [[BIP 0039]] recovery seed.  This means it is not necessary to store your private keys on KeepKey: the recovery process is secure enough so that KeepKey can be used as a transaction device for paper wallets. &lt;br /&gt;
