G-Knot, a pioneering biometrics technology company, announced the launch of its limited presale for the world’s first finger vein crypto wallet – the first commercially available hardware wallet secured by finger vein biometrics. This advanced system employs near-infrared (NIR) light in the 630-1,000 nm range to penetrate the skin and illuminate the finger, where a specialized CCD camera and optical filter capture the absorption patterns of deoxygenated hemoglobin in the veins—forming a unique, subsurface vascular map that’s invisible to the naked eye and highly resistant to external replication or spoofing. It analyzes subdermal vein patterns and live blood flow for nearly unforgeable authentication, eliminating recovery phrases, cloud-based keys, and spoofable security measures by offering users self-custody they can unlock with a simple gesture, where users fully own and control their biometrics with all data stored locally on the device.
The presale, beginning November 19th, includes a limited early-bird offer of $299 for the first 10,000 units. Each wallet purchase includes $50 worth of GKNT, the native token powering authentication and services across the G-Knot ecosystem. The wallet is expected to begin shipping in Q1 2026, alongside access to companion features and apps.
“The G-Knot wallet is a breakthrough in digital security, harnessing near-infrared light to map unique subdermal vein patterns and detect live blood flow through our patented P2N2 AI, ensuring authentication that’s nearly impossible to forge or spoof. It gives users the power to protect their crypto with technology that’s based on who they are, not what they remember,” said Wes Kaplan, CEO of G-Knot. “We’re building for a future where ownership and identity are truly personal. This presale is an opportunity to be part of that shift from day one.”
The GKNT token fuels authentication events, validator staking, and governance across the G-Knot network. Users can also earn rewards for securing their assets and participating in ecosystem activities. Businesses and individuals can use GKNT for hardware purchases and service payments, with built-in token burns and staking pool replenishments sustaining long-term value.
Built on over a decade of biometric R&D in partnership with eTunnel Inc., G-Knot’s wallet uses finger vein recognition technology that has been validated in national ID deployments and secured a contract with the United Nations’ International Telecommunication Union. The wallet’s proprietary P2N2 AI engine verifies identity based on subdermal vein patterns and real-time biological signals, completing authentication in under a second while keeping all biometric data stored locally. The captured image is processed by the patented P2N2 AI algorithm, which handles noise removal, precise finger isolation via edge detection, vein extraction using level set curvature analysis (modeling veins as “valleys” in topographic contours), binarization to create a binary vein skeleton, and thinning to generate a compact, secure biometric template. Liveness detection is integral, requiring real-time blood flow (pulsing veins) to authenticate and preventing spoofs from static images, prosthetics, or other fakes through dynamic NIR modulation that detects hemoglobin movement. For deeper security, finger-vein templates are encrypted and stored exclusively within an EAL 6+ Secure Element chip, with private keys derived directly from this encrypted, on-device template using modern cryptographic algorithms and zero-knowledge proofs for privacy-preserving verification without exposing raw data. The system supports multi-finger enrollment (up to 8 fingers, yielding 24 unique patterns) with AI-driven adaptation for biological variances like injuries, aging, or environmental factors, ensuring robust performance across conditions, with no external transmission, central storage, or collection by G-Knot or any third party—ensuring complete user privacy and control, as users fully own their biometrics.
The wallet natively supports Ethereum, Solana, BNB, and XRP, with more integrations coming as G-Knot expands its chain-agnostic ecosystem. Early adoption is expected to come from retail users, followed by institutions and eventually government-level digital identity programs.
