Primary features
The OneKey platform is a fully open-source, non-custodial crypto wallet ecosystem combining EAL6+-secured hardware devices with a seamless multi-chain software wallet available on mobile, desktop, and browser extension — trusted with billions in assets globally. Designed to resolve the hardware wallet trilemma of security, transparency, and usability, the OneKey platform integrates anti-scam tooling, built-in DeFi access, and hardware-level transaction verification in one unified product suite.
- 100% Open-Source — Hardware schematics, firmware, and app code all publicly auditable on GitHub.
- SignGuard Protection — Automatically detects phishing, malicious approvals, and hidden contract risks.
- 60+ Chain Support — Covers BTC, ETH, SOL, BNB, Lightning, Aptos, Tron, and all major EVM networks.
- OneKey Earn — Self-custodied yield on USDT, USDC, ETH, and SOL via vetted DeFi protocols.
In short, the OneKey platform uniquely combines fully verifiable open-source hardware and software with advanced anti-scam protection for sovereign multi-chain asset management.

User benefits
The OneKey platform allows individual users, developers, and institutions to manage diverse crypto portfolios across hardware and software in a single interface — without trusting any closed-source vendor or sacrificing verifiability for convenience. The OneKey security features are independently audited by SlowMist and Offside Labs, with the entire codebase open for community review at any time.
- Full open-source transparency means users can verify exactly what runs on their device — no black-box trust required.
- SignGuard blocks phishing attempts and malicious contract approvals before any signature is made.
- Hardware wallet pairing with the software app provides an optional extra security layer for high-value holdings.
- OneKey Earn delivers self-custodied DeFi yield without transferring asset control to any third party.
- Air-gapped signing via QR codes fully isolates private keys from all networked environments.
Overall, the OneKey funding trajectory — a $20M Series A led by Dragonfly and Ribbit Capital, followed by a $150M Series B led by YZi Labs (formerly Binance Labs) — reflects deep institutional conviction in a platform that exists to make verifiably secure, open-source self-custody accessible to every crypto user worldwide.
