OneKey Pro

The OneKey Pro is the flagship hardware wallet from Hong Kong-based open-source wallet maker OneKey, priced at $278 USD. It brings together four EAL 6+ certified secure element chips, a color touchscreen, fingerprint unlock, end-to-end encrypted Bluetooth, Qi2 wireless charging and air-gap QR signing — a feature combination that puts it directly against the Ledger Stax ($399) and Trezor Safe 5 ($169) at a mid-premium price.

Bank-vault-grade chip security. Four independent CC EAL 6+ Secure Element chips sit inside the Pro — the same certification level used in government IDs, passports and contactless EMV bank cards. EAL 6+ is the highest Common Criteria (ISO/IEC 15408) protection level used in mainstream hardware wallets today, with additional protections against physical tampering and side-channel attacks. The defense-in-depth chip architecture keeps the private keys isolated even if one chip is somehow compromised.

Clear Signing + real-time scam detection. Every transaction renders in human-readable form on the device's own color touchscreen before you approve — no blind signing — and behind the scenes the SignGuard database from OneKey Anzen Security Lab scans the contracts, tokens and dApps you interact with to flag malicious activity before you sign. Combined with air-gap QR signing and end-to-end encrypted Bluetooth, the Pro lets you transact on dApps without ever exposing the device to an online attack surface.

One wallet for 30,000+ coins. The Pro supports 30,000+ coins and tokens across 100+ blockchains including Bitcoin, Ethereum, USDT, Solana and XRP — and includes a dedicated Bitcoin-Only firmware mode for users who want a hardened BTC-only cold storage device. WalletConnect v2 and integration with MetaMask, OKX, Rabby and Sparrow means every NFT marketplace, DEX and lending protocol works out of the box.

4x EAL6+ Secure Elements — Bank-Vault Grade Chip

• Four independent CC EAL 6+ Secure Element chips — the same security certification level used in government IDs, passports and EMV bank cards.
• EAL 6+ is the highest Common Criteria (ISO/IEC 15408) protection level used in mainstream hardware wallets, with additional guarantees against physical tampering and side-channel attacks.
• Four chips provide defense-in-depth — even if one chip is somehow compromised, the remaining secure elements keep your private keys locked down.

Color Touchscreen with Clear Signing

• Built-in color touchscreen for tap-and-swipe navigation — feels like a modern smartphone.
• Clear Signing renders every transaction (amount, recipient, contract, function) in human-readable language on the device's own screen before you approve. No blind signing.
• Combined with the SignGuard real-time scam-detection database from OneKey Anzen Security Lab, the device warns you before you sign if anything looks phishy — duplicate contract, known malicious dApp, suspicious allowance amount, etc.

Air-Gap Signing + Fingerprint + Bluetooth + Qi2 Wireless Charging

• Air-Gap Signing via QR code — sign transactions 100% offline; exchange signed payloads with any phone or computer via QR scanning, with zero cables and zero Bluetooth required.
• USB-C wired pairing for desktop use.
• End-to-end encrypted Bluetooth for mobile pairing with the OneKey App.
• Qi2 wireless charging — drop the Pro on a Qi2 charging pad for both power and pairing. No cable required for day-to-day use.
• Integrated fingerprint sensor for one-tap unlock and transaction approval — holds up to 5 enrolled fingerprints.

1 Wallet. 100+ Chains. 30,000+ Coins.

• OneKey Pro supports 30,000+ coins and tokens across 100+ blockchains — covering Bitcoin, Ethereum, USDT, Solana, XRP and virtually every major network.
• Dedicated Bitcoin-Only firmware mode for users who only want to cold-store BTC.
• Integrates natively with WalletConnect v2 and leading browser wallets including MetaMask, OKX, Rabby and Sparrow.
• NFTs and DeFi ready out of the box — connect to OpenSea, Uniswap, Aave, Curve, PancakeSwap and thousands of other dApps.

Open-Source & Independently Audited

• Firmware and apps are fully open-source and reproducible on GitHub — anyone can verify the binary on your device was built from the public source.
• Independently audited by SlowMist — the audit report is published publicly.
• Adopted and invested in by Coinbase Ventures and Binance Labs (now YZi Labs), while remaining fully operationally independent.

Tamper-Evident Packaging

• Every Pro ships in tamper-evident packaging so you can verify the box was never opened between the factory and your hands.
• Guided 5-minute onboarding with fingerprint enrollment and intuitive UX on the touchscreen — feels natural even for first-time crypto users.

OneKey is an open-source hardware-wallet company founded in 2019 and incorporated in Hong Kong. The company is best known for being one of the most transparent hardware-wallet vendors in the industry — its firmware, micro-controller code and apps are fully open-source and reproducible on GitHub, with independent security audits published by SlowMist and other firms.

OneKey is venture-backed by Coinbase Ventures, Binance Labs (now YZi Labs) and a small group of crypto-native funds, while remaining operationally independent. Its product family includes the budget OneKey Classic (button-driven hardware wallet), the card-shaped OneKey Touch, and the flagship OneKey Pro reviewed here.

The company operates its own internal security research lab OneKey Anzen Security Lab (信澤 安全 实驗室), which produces the real-time scam-detection SignGuard database shipped inside the OneKey Pro firmware. OneKey also runs the browser-based and mobile OneKey App, an all-in-one companion for managing the device across iOS, Android, macOS, Windows, Linux and Chrome OS.
