'''TREZOR is a hardware wallet providing security for your bitcoins by virtue of its design while retaining convenience of use. No matter whether you're a beginner or a security-paranoid geek.'''

Unlike a cold storage (offline storage or paper wallet), TREZOR is also able to send bitcoins in a secure way. Without the need to expose your private keys to a potentially compromised computer.

More on the security principles here:

* [http://doc.satoshilabs.com/trezor-user/securityphilosophy.html Philosophy of Security]

== How does it work? ==
[[File:Trezor_White_Cafe_Polis.JPG|300px|thumb|right|Be Your Own Bank with TREZOR]]
TREZOR is basically a small computer. It is designed to protect your private keys from possible online and offline risks. In order to do this, TREZOR keeps the private keys away from the Internet and confirms the transactions in-device. That way you can always check the screen for the right address, amount and transaction fee before sending your bitcoins.

In layman's terms you can connect TREZOR to an infected computer and still be able to have 100% control over the funds in your device.

* [http://doc.satoshilabs.com/trezor-faq/threats.html Security Threats]

== Using TREZOR ==

TREZOR needs an online wallet or other client as a user interface. To ensure validity of communication between the device and the interface TREZOR uses pin scrambling matrix. See more here.

=== Sending transactions ===

Have a look how easy and comfortable it is to send transactions:

=== Receiving address phishing protection ===
[[File:Checkaddress_comp.png|300px|thumb|right|Show on TREZOR]]
[[File:Checkaddress_comp2.png|300px|thumb|right|Show on TREZOR]]

Make sure that the receiving address you have provided to someone else has not been changed by infected computer. Feature "Show on TREZOR" has been developed exactly for this purpose:

* [http://doc.satoshilabs.com/trezor-user/receivingpayments.html Receiving payments]

=== Sign & Verify messages ===

It is also possible to sign and verify messages using TREZOR:

* [http://doc.satoshilabs.com/trezor-user/messages.html Sign & verify messages]

[[File:Trezor_verify_message.png|300px|thumb|right|Verified message]]

=== Backup and recovery ===

Upon first activation you are asked to write down the seed phrase.

This means that in case your TREZOR is lost or stolen you can easily retrieve your coins to another TREZOR or any recovery seed compatible wallet.

* [http://doc.satoshilabs.com/trezor-user/recovery.html Recovery procedure]

=== Advanced Settings ===

You can further improve the security (except the totally new way of entering PIN - see above) by using passphrase encrypted seeds and multiple passphrases to create so called "Hidden Wallets". More details here:

Hardware wallet

2015-04-29T13:22:26Z

Qwc23:

A '''hardware wallet''' is a device that stores a part of a user's [[wallet]] securely in mostly-offline hardware. They have major advantages over other wallet types:

* the key is often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext
* immune to computer viruses that steal from software wallets
* can be used securely and interactively, as opposed to a [[paper wallet]] which must be imported to software at some point
* much of the time, the software is open source, allowing a user to validate the entire operation of the device

This page is an attempt to summarize all the known developments of hardware wallets that can use Bitcoin as part of their operation.

== Purchasable hardware wallets (ordered chronologically) ==

=== Pi Wallet - cold storage ===
[[File:Piwallet.jpeg|300px|thumb|left|Pi-Wallet]]
[http://www.pi-wallet.com/ Pi-Wallet Shop]

[http://www.pi-wallet.com/pages/what-is-pi-wallet Further informations about Pi-Wallet]

The Pi-Wallet is comparable to an offline Notebook.

However it combines all features of the Armory bitcoin client (e.g. offline transaction signing) with the advantages of a tiny computer.

To sign offline-transaction you will need an (unused) USB stick.

 

=== [[TREZOR]] The Bitcoin Safe ===
[http://bitcointrezor.com BitcoinTrezor.com]

[[File:Trezor-tx.jpg|300px|thumb|left|Confirming the transaction with TREZOR]]

[[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.

It uses a deterministic wallet structure which means it can hold an unlimited number of keys (BIP32/BIP44). 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 BIP39/BIP44 compatible wallet.

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.

=== BTChip HW.1 - USB Smartcard Hardware Wallet ===
[https://www.hardwarewallet.com HW.1 Home Page]

[[File:Btchip_dongle.jpg|220px|thumb|left|HW.1 inserted in a laptop]]

HW.1 is an implementation of a deterministic (BIP 32) Hardware Wallet on a USB smartcard.

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.

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.

It is also possible to customize HW.1 for more specfic 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.

=== Ledger Wallet - USB Smartcard Hardware Wallet ===

[[File:ledger_wallet_photo.jpg|300px|thumb|left|Ledger Wallet USB]]

Ledger Wallet 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 Ledger Wallet 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.

It is compatible with Electrum 2.0 for power users, or with the Ledger Wallet Chrome application which provides an easy onboarding as well as a seamless user experience.

=== [[BWALLET]] TREZOR clone ===

[[File:BWALLET_Trezor_Clone.jpeg|200px|thumb|left|Chinese clone of Trezor]]

[[BWALLET]] is a clone of Trezor by a Chinese company.
Trezor code is open source and this device operates exactly like a Trezor.
In fact, in can be setup and used on the [http://mytrezor.com MyTrezor.com] website.
All information about Trezor listed above applies to this device as well.

[http://blog.bitinstant.com/blog/2012/6/19/our-discovery-in-vienna-the-bitcoin-card.html Excellent review by evoorhees]

Incorporates a e-paper display, keypad, and radio (custom ISM band protocol.) Unfortunately it is fairly limited in terms of transaction I/O, requiring a radio gateway or another bitcoincard wherever funds need to be transferred.
