G-Knot: A New Finger Vein Biometric Crypto Wallet Aiming to Redefine Security and Design
G-Knot is a new hardware wallet that leverages finger vein biometrics to unlock access, aiming to outperform established competitors like Ledger and Trezor in security and design. The unlocking process relies on recognizing the unique finger vein pattern and live blood flow of the user, employing zero-knowledge proofs to power a local process. This eliminates the need for seed phrases, PIN codes, or private keys for sign-in. Additionally, a two-factor authentication code is required to unlock the connected smartphone app.
Supporting multiple cryptocurrencies including Bitcoin, Ethereum, Solana, BNB, and XRP, the Bluetooth-enabled wallet is rechargeable via USB-C. The Founder’s Edition is offered in a pre-sale for $299, with 10,000 units available and shipping scheduled for January. The project is led by a team connected to a Korean biometric security firm, using a patented finger vein scanner already utilized by the International Telecommunication Union (ITU) at its Geneva headquarters.
Multi-signature functionality is currently under development, enabling unlocking only when multiple G-Knot devices sign in from different locations. CEO Wes Kaplan emphasizes that the system removes the seed-phrase single point of failure and focuses on providing a modern, user-friendly experience. The G-Knot wallet is positioned as a premium, design-forward option, priced higher than Ledger Nano Gen5 ($179) and Trezor Safe 7 ($249).
