What is TAPSIGNER?

The TAPSIGNER is an elegantly designed NFC-enabled smart card that safely keeps your Bitcoin private key (XPRV) and facilitates effortless transaction signing by simply tapping it against your smartphone. With its verifiable entropy feature, you can confidently rely on the TAPSIGNER as the sole holder of your Bitcoin private key. This smart card can be easily backed up to a file, allowing it to function as a compact and portable Bitcoin wallet. Envision the convenience of having a Bitcoin private key in an easy-to-carry card format! By tapping the TAPSIGNER on your mobile device, you can sign transactions while your mobile wallet handles the majority of the processing, ensuring that sensitive information remains secure within the card. Serving as a hardware wallet, it can fit seamlessly into your everyday wallet, making it a highly practical security solution. The cost-effectiveness of the TAPSIGNER expands the availability of hardware wallet features and security measures for users around the world. Furthermore, it provides an excellent way to keep your private keys separate from other wallets, ensuring additional safety. With its card-like design, the TAPSIGNER is not just portable but also discreet, and it supports partially signed Bitcoin transactions (PSBTs) via HWI, significantly increasing its overall functionality for users. This innovative device combines convenience and security, making it an ideal choice for both novice and seasoned Bitcoin holders alike.

What is NGRAVE?

The NGRAVE hardware wallet functions completely offline, which guarantees that your private keys are safeguarded and never come into contact with any device that connects to the internet. Developed in partnership with specialists in the fields of nano-technology and hardware security, this wallet features a wallet generation process that is regarded as the most advanced in the world. In addition to the hardware, NGRAVE provides a mobile application that effortlessly syncs with all accounts established on the ZERO wallet, enabling users to monitor their balances in real-time and initiate transactions with ease. Communication between the ZERO wallet and the mobile app is conducted through QR codes, ensuring that the app cannot access the secret keys stored in the ZERO wallet, thereby shielding them from any online vulnerabilities, even during the process of signing transactions. Users can create a highly secure, unique, and unpredictable secret key using a robust True Random Number Generation (TRNG) method. NGRAVE places a strong emphasis on security while simultaneously enhancing the overall user experience at every stage, thereby ensuring the most secure practices for the generation and management of wallets. Overall, it provides cryptocurrency enthusiasts with an unmatched level of cold storage, making it a highly reliable choice for digital asset security. Furthermore, the combination of cutting-edge technology and user-centric design truly sets NGRAVE apart in the cryptocurrency landscape.
