About

100% air-gapped QR code solution Cold wallet. First hardware wallet Integrated with MetaMask Mobile. By using QR code transmissions, we have eliminated potential malware infiltration risks and delivered a level of transparency that just isn't possible with Bluetooth or USB. A proprietary bank-grade Secure Element ensures your private keys never leave the Keystone. The Secure Element generates a true random number for your private keys and is vital to ensuring your crypto assets are stored in the safest way possible. Our BIP32, BIP39, and BIP44 compliant firmware is also open source. Keystone has pioneered the hardware wallet industry’s first open source Secure Element firmware. It allows you to see how private keys are derived from physically generated entropy (TRNG) and stay entirely confined within the Secure Element. Our hardware wallet application layer, device schematic (circuit diagram), and bill of materials (BOM) are also open source.

About

It's a wireless NFC smart card that holds your Bitcoin private key (XPRV) and will sign transactions with a simple tap on your phone. Verifiable entropy, meaning you know 100% that no one but the TAPSIGNER itself has the private key that controls the Bitcoin. Can be easily and securely backed up into a file. A simple Bitcoin wallet in your pocket. Think of it as a Bitcoin private key on a card! You can sign mobile wallet transactions by tapping the card on your phone. Your mobile wallet provides most of the wallet logic and TAPSIGNER holds the secrets. It's essentially a hardware wallet you can slip inside your regular wallet. TAPSIGNER's lower cost makes hardware wallet features and security available to a wider market around the world. TAPSIGNER is a great way to keep your keys separate from your wallet(s). The card form factor makes it easy to carry and easy to conceal. Partially signed Bitcoin transactions (PSBTs) via HWI.

Pros & Cons from Real Users

Pros

  • Metamask is by far the best option for DeFi but hot wallets are very risky by nature. Luckily there are several hardware wallet options for Metamask PC/Mac (Trezor and Ledger being the most popular). However, neither of those 2 companies work with Metamask mobile. This is where Keystone shines. Now you have the ability to use Metamask on the go but keep your DeFi assets safely protected by the Keystone hardware wallet. Integration with Metamask is excellent and now I am safe knowing my Metamask wallet won't be hacked.
  • 1. Great customer support with quick responses 2. Only hardware wallet got integrated with MetaMask Mobile 3. Heard that they have developed in the community more than 5 years, quite a promising brand
  • 1. The QR code is a great way to make sure that the Keystone wallet is not connected to the internet. 2. Confirming the recovery phrase is one of a kind experience, way much better than other hardware wallets I used before. 3. Open-source nature of their Secure Element makes me feel safe when I create a new wallet.
  • 100% Air gapped, Fully integrated with MetaMask, The only hardware wallet supported by MetaMask mobile. The 4-inch screen makes it very user friendly and make the transaction more transparent. Solved blind-signing. Support are very reactive.

Cons

  • The battery system needs to be upgraded.
  • 1. Doesn't have enough coin support yet, hope to see Doge in the list
  • The number of coins they support is limited right now, but it seems that they have been integrating with many soft wallets on various chains in the past few months.
  • Company app doesn't support swap, the team believe the future of blockchain is a multi-chain one, therefore, the team is aiming at become the extra security layer of all the popular software wallets.
