- The wallet eliminates seed phrases and pins, using vascular patterns verified locally via zero-knowledge proofs.
- Supports major cryptocurrencies including Bitcoin, Ethereum, Solana, BNB, and XRP.

A new cryptocurrency hardware wallet called G-Knot launched a presale today for its “Founder’s Edition,” priced at $299 per unit. Developed by a team connected to a Korean biometric security firm, this device aims to improve security by replacing traditional methods such as seed phrases or PIN codes with finger vein scanning technology. The product is expected to ship in January.
The device is designed as a puck-shaped wallet with a touchscreen and a dedicated finger vein scanner that reads the blood flow and unique vascular architecture of a user’s finger. This biometric data is processed locally using zero-knowledge proofs, a cryptographic method that verifies identity without sharing sensitive information. After scanning, users enter a two-factor authentication code to access their crypto wallets through an associated smartphone app.
G-Knot supports popular cryptocurrencies such as Bitcoin, Ethereum, Solana, BNB, and XRP. The company states that the technology requires live blood flow, preventing unauthorized access through severed fingers. Each finger’s vein pattern is unique and permanent, reducing risks associated with biometric forgery.
Plans to introduce multi-signature (multi-sig) capabilities are underway, enabling wallets to require multiple users to sign in from different locations simultaneously for added protection. This technology already secures facilities like the International Telecommunications Union’s Geneva headquarters, a United Nations digital technology agency.
Due to recent high-profile kidnappings targeting cryptocurrency holders, the G-Knot aims to provide a security-focused, user-friendly solution without the need to manage vulnerable recovery phrases or private keys. The company anticipates that its combination of biometric security and ease of use will appeal to crypto users seeking stress-free cold storage.
The “Founder’s Edition” presale offers 10,000 units with an aluminum shell. The $299 price point is above competitor hardware wallets such as Ledger’s Nano Gen5 ($179) and Trezor’s Safe 7 ($249). The company believes this premium is justified by superior security features and streamlined user experience.
