			=== Frostsnap ===
			[[File:Frostsnap Hardware Wallet.png\|200px\|thumb\|left\|Frostsnap devices daisy-chained into a mobile phone. Choosing a threshold for the multisignature wallet.]]

			Frostsnap hardware wallets make [[multisignature]] security simple. Each wallet consists of a set of Frostsnap devices and a chosen threshold (e.g. 2-of-3). The wallet's key is created through distributed key generation and never exists on any one device; transactions are signed using [https://eprint.iacr.org/2020/852 FROST], so only a threshold of devices cooperating can produce a signature.

			Frostsnap's multisignature is enforced through mathematics rather than [[Script\|Bitcoin script]]. Transactions are signed with an ordinary [[Schnorr]] signature spending a [[Taproot]] key path. With a single group public key, Frostsnap wallets are indistinguishable on-chain from single-signature Taproot wallets, paying single-signature fees and revealing nothing about the signing policy.

			Main features:
			* Recovery needs only a threshold of devices or backups, with no descriptor metadata to back up
			* No individual device is trusted: the phone verifiably contributes entropy to key generation and signing, protecting against weak randomness, supply chain attacks, and devices leaking secrets through their signatures (see [[Hardware wallet#Security risks\|Security risks]])
			* Losing a device below the threshold loses nothing; stealing a device below the threshold gains nothing
			* No PINs or passphrases to complicate recovery or inheritance
			* No vendor lock-in: a threshold of backups reconstructs a key spendable without Frostsnap hardware or software
			* Touchscreen, USB-C, aluminium casing; app for Android, Linux, macOS and Windows
			* Fully open source (MIT), written in [https://www.rust-lang.org Rust], with reproducible firmware builds

	[[Cypherock]] ~~has~~ a ~~unique private key management system~~ that ~~eliminates the need for maintaining~~ seed phrase ~~backups, allows import of existing BIP39 compatible wallets, and solves for crypto inheritance without compromising privacy and control of your Bitcoins~~.		[[Cypherock Wallet]] is a secure Bitcoin hardware wallet that does not require a manual seed phrase backup.

	Cypherock uses [[Shamir Secret Sharing]] to ~~shard~~ the ~~private key of the wallet~~ into 5 tamper-proof hardware components - namely the X1 ~~wallet~~ and 4 X1 cards. These hardware components interact with each other using NFC technology. Using a 2-of-5 threshold scheme, any 2 of the 5 ~~shards~~ can be used to reconstruct the private key and make transactions.		Cypherock X1 uses [[Shamir Secret Sharing]] to break the master seed into 5 Cryptographic parts further stored on 5 tamper-proof hardware components - namely the X1 vault and 4 X1 cards. Each of these 5 components can have an optional PIN set by the user as an additional layer of security. These hardware components interact with each other using NFC technology. Using a 2-of-5 threshold scheme, any 2 of the 5 parts can be used to reconstruct the private key and make transactions.
