Tapsigner

The Tapsigner by Coinkite is the ultimate blend of security and convenience for managing your Bitcoin. This wireless NFC smart-card securely holds your Bitcoin private key (XPRV) and allows you to sign transactions with just a simple tap on your phone. Designed to work seamlessly with popular wallet apps like Nunchuk (iOS, Android, Desktop) and Sparrow (Desktop), the Tapsigner ensures a smooth and secure Bitcoin experience.

What makes the Tapsigner truly stand out is its verifiable entropy, guaranteeing that only the Tapsigner itself holds your private key, providing you with 100% confidence in your Bitcoin's security. Plus, it can be easily and securely backed up into a file, giving you complete peace of mind.

Think of the Tapsigner as a Bitcoin private key on a card—a powerful yet simple tool that allows you to sign mobile wallet transactions effortlessly. With Nunchuk or Sparrow handling most of the wallet logic, the Tapsigner keeps your private keys safe, effectively functioning as a hardware wallet that conveniently fits inside your regular wallet.

Tapsigner’s affordable price point makes hardware wallet features and security accessible to a broader audience, making it easier than ever to secure your Bitcoin. Its NFC card form factor provides a fast and easy user experience while being easy to carry and conceal, keeping your Bitcoin keys separate from your wallet(s) for added security.

Ideal for a wide range of uses, from phone wallet cosigning and managing Lightning Network channels to message signing and collaborative multisig services, the Tapsigner is a versatile and secure solution. Whether you’re dealing with raw transactions, partially signed Bitcoin transactions (PSBTs) via HWI, or app authentication, the Tapsigner is up to the task.

The Tapsigner by Coinkite is a simple, secure, and portable Bitcoin wallet in your pocket, designed to work great with Nunchuk and Sparrow Wallets, and ready to bring top-tier security and ease of use to your everyday Bitcoin transactions.
