G-Knot Launches Biometric Hardware Wallet Secured by Finger Vein Authentication
Startup G-Knot has introduced a new hardware crypto wallet that replaces passwords and seed phrases with biometric authentication based on finger vein scanning. The device aims to redefine hardware wallet security by eliminating traditional recovery methods and relying on a biometric signature that cannot be replicated.A New Approach to Crypto Security
Instead of using PIN codes, seed phrases, or recovery sheets, the G-Knot wallet authenticates owners by analyzing the vascular patterns inside their fingers. According to the company, this method provides stronger protection than fingerprints or facial recognition because vein structures exist beneath the skin and are extremely difficult to spoof.The device supports up to eight biometric profiles, allowing multiple trusted users or backup scans from the same owner.
Round Form Factor With a Touchscreen Interface
The hardware wallet comes in a unique puck-shaped design equipped with a small touchscreen. Users interact with the device through the display, while the biometric sensor captures and validates their vein pattern in real time.G-Knot emphasizes that all biometric data remains strictly on the device. It is encrypted locally and never transmitted externally, aligning with privacy-first principles.
Zero-Knowledge Proofs for Secure Authentication
To further enhance privacy, the wallet uses zero-knowledge proof mechanisms. This means verification occurs without exposing the biometric data itself. G-Knot states that only a live finger with blood flow can unlock the device, protecting it from spoofing attempts such as replicas, casts, or high-resolution prints.Supports Major Cryptocurrencies
The wallet is compatible with several leading assets, including Bitcoin, Ethereum, Solana, BNB, and XRP. The company plans ongoing expansion of supported chains through firmware updates.This makes the device suitable for users operating across multiple ecosystems, including traders, investors, and DeFi participants.
Pricing, Availability, and Bonus Tokens
The first batch of 10,000 devices is priced at 299 dollars. Early buyers also receive GNOT tokens and access to future airdrops, adding an incentive layer for adopters.According to the team, demand for hardware wallets with advanced authentication is growing as users seek protection from phishing, seed phrase theft, and physical compromise.
A Step Toward Seedless Hardware Wallets
G-Knot joins a new wave of companies experimenting with seedless, self-contained authentication systems. If the technology proves reliable in real-world conditions, biometric hardware wallets may become a major alternative for users seeking strong security without the burden of mnemonic management.Editorial Team — CoinBotLab
