OneKey

Per the official onekey.so /products/onekey-pro page (July 2026): "OneKey Pro — Secure. Swift. Cold storage, reimagined." OneKey Pro is OneKey's flagship open-source crypto hardware wallet device, priced at $278 USD. It is the highest-tier device in OneKey's product lineup (which also includes OneKey Classic 1S, OneKey Classic 1S Pure, OneKey Classic 1S Pure BTC-Only Edition, OneKey KeyTag titanium backup, OneKey Lite encrypted-backup card, and the OneKey Sifu 1-on-1 onboarding service.

OneKey is a Singapore-headquartered open-source crypto hardware-wallet company founded in 2019 by Yuesheng Ge (CEO). The company shipped its first hardware wallet in 2020 and has grown into one of the most-respected open-source crypto hardware companies globally. Per the official onekey.so homepage (July 2026): "OneKey to All Finance — Self Custody. Open Source. Fully Onchain. Trade crypto, stocks, and more from your OneKey Wallet." This positions OneKey uniquely in the market — a hardware-wallet-first crypto company whose software stack (the OneKey App + browser extension + web app at app.onekey.so) covers both crypto AND traditional financial assets ("Trade global assets. Start with your email in minutes" — per the OneKey App product block on the homepage).

The unique-and-flagship credential OneKey holds, per the official onekey.so newsroom headline (July 2026): "The only hardware wallet backed by both YZi Labs (Prev. Binance Labs) and Coinbase Ventures". This dual endorsement from the venture arms of the world's two largest crypto exchanges is a strong competitive signifier — no other hardware wallet in the market has this dual endorsement. Additional investors include Dragonfly, Ribbit Capital, Bixin Ventures, Framework, Sky9 Capital, Ethereal, Folius Ventures, and SRS Investment Holdings — listed on the homepage's "Backed by top global funds" section.

Per the official /products/onekey-pro page: OneKey Pro's headline security spec is "Built with 4 EAL 6+ Secure Elements". The page expands: "Built with 4 EAL 6+ Secure Elements, the same level of chip security used in government IDs, passports, and EMV bank cards." EAL 6+ (Evaluation Assurance Level 6+) is a globally recognized high-assurance standard under the Common Criteria (ISO/IEC 15408), with additional protections against physical tampering and side-channel attacks. This is the highest chip-security tier currently seen on a consumer hardware-wallet product — exceeding the EAL 5+ secure element used in the Ledger Nano X / Stax / Flex line and matching the EAL 6+ used in the Trezor Safe 5.

Per the official /products/onekey-pro page: OneKey Pro's security works on three layers — (1) Hardware with the EAL 6+ secure elements; (2) Software/firmware that is fully open source at github.com/onekeyhq with reproducible builds + an independent SlowMist security audit + the company's reported "Zero Losses Since Inception" track record; (3) Defense-in-depth software intelligence via the OneKey Anzen Security Lab's Sign Guard — a real-time scam-detection system that analyzes every contract, token, and dApp to spot scams and threats during the signing flow (comparable to Blockaid + Wallet Studio + Tenderly transaction-simulation safety nets, but built into the wallet firmware/software by OneKey itself).

OneKey Pro's UX is a major differentiator. Per the /products/onekey-pro page: "Set up. Secure. In 5 minutes. — Guided onboarding, fingerprint unlock, and an intuitive UX on a crisp touchscreen. Everything feels natural even for first-time crypto users." The premium industrial design + the 5-minute onboarding flow make OneKey Pro one of the most beginner-friendly hardware wallets on the market — comparable to the Trezor Safe 5 and Ledger Flex's beginner-friendliness, with the added polish of fingerprint-biometric unlock and Qi2 wireless charging.

The full OneKey product stack (per onekey.so homepage): (1) OneKey Pro (flagship hardware wallet, $278); (2) OneKey Classic 1S (slimmer entry-tier hardware wallet — "The slimmest wallet, built for security"); (3) OneKey Classic 1S Pure (battery-free entry-tier, "Battery-free. Made to HODL."); (4) OneKey Classic 1S Pure BTC-Only Edition ("Circuitry, laid bare. No battery. No secrets. Just raw industrial art."); (5) OneKey KeyTag (titanium seed-phrase backup kit — "Unbreakable titanium backup kit"); (6) OneKey Lite (military-grade encrypted backup card); (7) OneKey Sifu (1-on-1 wallet-setup service with OneKey Experts — a paid-concierge onboarding service, very unusual among hardware wallet makers); (8) OneKey App (desktop + mobile wallet software — "The ultimate all-in-one crypto wallet. Trade global assets. Start with your email in minutes."); (9) OneKey Browser Extension (connects OneKey hardware wallet to any dApp you love — comparable to MetaMask but with hardware-wallet-first signing); (10) OneKey Web App (browser-launched wallet interface at app.onekey.so — "Plug and play, no downloads").

EAL 6+ certified secure elements — bank-vault-grade chip security

Per the official /products/onekey-pro page: "Built with 4 EAL 6+ Secure Elements, the same level of chip security used in government IDs, passports, and EMV bank cards." EAL 6+ (Evaluation Assurance Level 6+) is a globally recognized, high-assurance standard under the Common Criteria (ISO/IEC 15408), with additional protections against physical tampering and side-channel attacks. OneKey Pro uses 4 separate EAL 6+ chips in its design — this is the highest chip-security tier currently seen on a consumer hardware-wallet product (exceeding Ledger's EAL 5+ on Nano X / Stax / Flex and matching the EAL 6+ Trezor Safe 5). Each transaction is secured by these chips, which protect the user's private keys even if the device is physically stolen, opened, or side-channel-attacked.

Air-Gap Signing — fully offline transaction signing

OneKey Pro supports Air-Gap signing — the user generates the unsigned transaction in the OneKey App, then signs it on the OneKey Pro hardware device offline (the device never connects to the internet for signing — it only needs power, which can be supplied by the wireless Qi2 charger or USB-C). The signed transaction is then broadcast back to the connected computer/phone for onchain submission. Per the official newsroom (July 2026): "MetaMask now supports Air-Gap connection for OneKey hardware wallets" — meaning MetaMask users can now sign with OneKey Pro via an Air-Gap connection (extending OneKey's air-gap compatibility to the largest browser wallet ecosystem).

Fingerprint biometric unlock + 5-minute setup

Per the official /products/onekey-pro page: "Set up. Secure. In 5 minutes. — Guided onboarding, fingerprint unlock, and an intuitive UX on a crisp touchscreen." The fingerprint sensor on the device unlocks the wallet for signing — much simpler than typing PINs on hardware buttons (the model used by Ledger Nano X / Trezor Safe 3 / Coldcard Mk4). The first-time onboarding flow is fully guided and beginner-friendly.

Qi2 wireless charging + Bluetooth + full platform support

OneKey Pro supports Qi2 wireless charging — the latest wireless charging standard (Qi2 is a 2023 spec compatible with MagSafe phones and most modern wireless-charging accessories). Together with end-to-end encrypted Bluetooth, OneKey Pro can connect to a phone or computer entirely wirelessly — no USB-C cable needed for either charging or signing. USB-C is also supported for users who prefer wired connection. Full platform support covers iOS + Android + macOS + Windows + Linux + the OneKey Browser Extension (Chrome / Edge / Firefox / Brave / Arc).

Real-time scam detection — Sign Guard by OneKey Anzen Security Lab

Per the official /products/onekey-pro page: "A defense system that analyzes every contract, token, and dApp in real time to spot scams and threats, built by the OneKey Anzen Security Lab." Sign Guard is a real-time scam-detection engine built into the OneKey signing flow — comparable to Blockaid + Wallet Studio + Tenderly's transaction-simulation safety nets, but built natively by OneKey. When you sign a transaction to an unknown / flagged contract, Sign Guard warns you before you sign. This is a major safety feature for users accepting signing requests through WalletConnect (a common attack surface for phishing-signing attacks where users are tricked into signing malicious transactions).

Clear Signing — human-readable transaction preview

Per the official /products/onekey-pro page: "Preview on-chain transactions with human-readable details before you confirm." Clear Signing decodes the raw transaction call data into human-readable intent — e.g. instead of showing an opaque hex contract call, OneKey Pro shows "Transfer 1.20 BTC to Account 2 — Taproot" with the recipient address + amount + transaction fee clearly visible on its touchscreen (per the homepage screenshot of the Clear Signing preview UI in July 2026). This protects against blind-signing attacks where users sign without understanding what they're approving (a major historical attack vector on Lesser-wallets like MetaMask). This is comparable to Ledger's Blind-Signing-Rejected feature and Trezor's "Turn Blind Signing Off" feature, both of which enforce human-readable previews before hardware-wallet signature.

Bitcoin-Only firmware support

Per the official /products/onekey-pro product page: OneKey Pro supports an optional Bitcoin-Only firmware mode — the user can flash a Bitcoin-only firmware that only supports the Bitcoin network, disabling all altcoin support. This reduces the attack surface (fewer code paths = fewer potential vulnerabilities) and is the gold standard for Bitcoin maximalists (parallels the Bitcoin-Only firmware option on Coldcard Mk4 + Foundation Passport + Blockstream Jade + Keystone 3 Pro). The full multi-coin firmware is also available for users who want to hold altcoins (Ethereum, Solana, XRP, 100+ chains, 30,000+ coins as advertised by OneKey Pro).

100+ chains and 30,000+ coins supported

Per the official /products/onekey-pro page: "1 Wallet. 100+ Chains. 30,000+ Coins. — Supports Bitcoin, Ethereum, USDT, Solana, XRP and 30,000+ other coins & tokens." This is one of the largest coin support counts of any hardware wallet — comparable to Ledger Live (5,500+ coins) + Trezor Suite (9,000+ coins) but with the added integration to Solana and XRP. OneKey Pro is the rare hardware wallet that natively supports both EVM chains AND non-EVM chains (Solana, XRP, Cosmos, etc.) in the same firmware.

WalletConnect v2 + MetaMask + OKX + Rabby + Sparrow integration

Per the official /products/onekey-pro page: "Works with WalletConnect v2 and leading browser wallets like MetaMask, OKX, Rabby, and Sparrow." OneKey Pro connects to any WalletConnect-compatible dApp via the WalletConnect v2 standard — this is compatible with hundreds of major dApps including Uniswap (Ethereum), Jupiter (Solana), PancakeSwap (BSC), Curve (multi-chain), Aave (DeFi), and more. Per the newsroom: "Sparrow now supports connecting the OneKey hardware wallet" and "MetaMask now supports Air-Gap connection for OneKey hardware wallets" — these recent integration announcements confirm OneKey Pro's broadening software compatibility surface.

OneKey App — Trade global assets, start with your email in minutes

Per the official homepage's OneKey App product block: "The ultimate all-in-one crypto wallet. Trade global assets. Start with your email in minutes." OneKey's software app (iOS + Android + desktop) is unique among hardware-wallet ecosystem apps — it supports both crypto AND traditional financial assets ("Trade crypto, stocks, and more"). This positions OneKey as a full financial-software platform with the hardware-wallet at its core — comparable to Revolut's integrated crypto+stocks trading in a single wallet app, but centered on a hardware-wallet-first custody model.

OneKey Sifu — 1-on-1 onboarding service

A paid concierge onboarding service where OneKey Experts help you set up your hardware wallet, migrate from another wallet, configure security best-practices, and answer any wallet questions. Very unusual among hardware wallet makers — most leave onboarding entirely to documented self-service. OneKey Sifu is positioned for high-net-worth individuals and crypto-curious users who want personalized help.

EAL 6+ certified secure elements — 4 separate chips, the same level used in government IDs and EMV bank cards

OneKey Pro uses 4 separate EAL 6+ certified secure elements. Per the official /products/onekey-pro page: "Built with 4 EAL 6+ Secure Elements, the same level of chip security used in government IDs, passports, and EMV bank cards." EAL 6+ (Evaluation Assurance Level 6+) is a globally recognized, high-assurance standard under the Common Criteria (ISO/IEC 15408). The "+" denotes additional protections against physical tampering and side-channel attacks (acoustic + electromagnetic emissions during signing that could leak keys).

This is the highest chip-security tier currently seen on a consumer hardware-wallet product. Compare: - OneKey Pro: EAL 6+ (4 separate secure elements) - Trezor Safe 5: EAL 6+ (single EAL 6+ secure element) - Ledger Nano X / Stax / Flex: EAL 5+ (single EAL 5+ secure element) - Coldcard Mk4: dual EAL 5+ secure elements - Keystone 3 Pro: EAL 5+ secure element OneKey Pro's 4 separate EAL 6+ chips are the highest confidence chip tier available in any consumer hardware wallet.

Fully open source + reproducible builds + SlowMist audit

Per the official /products/onekey-pro page: "Firmware and apps are fully open source and reproducible on GitHub, with reproducible builds and independent audits by SlowMist." All OneKey Pro firmware + app source code is at github.com/onekeyhq under open-source license. The reproducible-build statement means any independent auditor can rebuild the published firmware binaries from the open-source code and verify a byte-for-byte match — proving that the binaries OneKey ships are exactly the code on GitHub (no hidden additions, no closed-source components, no backdoors).

The SlowMist audit is publicly published: SlowMist's OneKey Pro Audit Report is available on the SlowMist Knowledge-Base GitHub. SlowMist is one of the most-respected blockchain security auditing firms in Asia, founded in 2018.

Zero losses since inception — strong track record

Per the official /products/onekey-pro page: "Code Audited. Zero Losses Since Inception." OneKey reports no-known user-private-key-loss incidents since the company's inception in 2019 — neither from firmware vulnerabilities, nor from supply-chain attacks, nor from device-side-channel attacks. This is a strong track record compared to the broader hardware-wallet industry, where Ledger, Trezor, and even Coldcard have had at least one public security incident in the last 5+ years (often resolved quickly without user-fund loss, but still incidents).

Tamper-evident packaging + supply-chain integrity

Per the official /products/onekey-pro page's "Secure before and after you use it" section: "Tamper-evident packaging ensures you can see if the box was opened." This protects against supply-chain attacks where an attacker might tamper with the device between shipping-from-OneKey and arrival-at-the-user. The tamper-evident packaging is one of the standard primary defense layers on all OneKey hardware wallet shipments — comparable to the same packaging model used by Ledger, Trezor, Coldcard, and Foundation Passport.

Sign Guard — real-time scam detection by OneKey Anzen Security Lab

Per the official /products/onekey-pro page: "A defense system that analyzes every contract, token, and dApp in real time to spot scams and threats, built by the OneKey Anzen Security Lab." Sign Guard is a runtime safety-net running on the OneKey signing flow. Whenever the user is asked to sign a transaction, Sign Guard runs a real-time analysis of the target contract (is it known-verified, known-scam, or unknown?), the target token (is it a known token or a honeypot?), and the dApp (is it a known dApp or a phishing mirror?). If anything is flagged, Sign Guard warns the user before they sign. This is comparable to Blockaid + Wallet Studio + Tenderly's transaction-simulation safety nets, but built into the native OneKey signing flow.

Clear Signing — human-readable transaction preview

Per the official /products/onekey-pro page: "Preview on-chain transactions with human-readable details before you confirm." Clear Signing on OneKey Pro decodes the raw transaction call data into human-readable intent on the device touchscreen — protecting against blind-signing attacks where users sign without understanding what they're approving. The larger crisp touchscreen of OneKey Pro (vs the smaller OLED screens on Ledger Nano X / Coldcard Mk4 / Trezor Safe 3) gives more on-screen room for the decoded intent + the recipient address + the transaction fee — making phishing harder to fall for.

Bitcoin-Only firmware mode — reduced attack surface option

OneKey Pro supports an optional Bitcoin-Only firmware mode that disables all altcoin support. This is the gold standard for Bitcoin maximalists wanting smallest attack surface — fewer code paths = fewer potential vulnerabilities. Parallels the Bitcoin-Only firmware options on Coldcard Mk4, Foundation Passport, Blockstream Jade, and Keystone 3 Pro (Cypherock X1 also has Bitcoin-Only firmware variants). The full multi-coin firmware is also available for users who want all altcoin features.

Backed by both YZi Labs (former Binance Labs) AND Coinbase Ventures + additional tier-1 venture firms

Per the official onekey.so newsroom headline (July 2026): "The only hardware wallet backed by both YZi Labs (Prev. Binance Labs) and Coinbase Ventures." No other hardware wallet company is backed by both of the world's two largest crypto-exchange venture arms. Additional investors include Dragonfly, Ribbit Capital, Bixin Ventures, Framework, Sky9 Capital, Ethereal, Folius Ventures, and SRS Investment Holdings. This tier-1 capital stack is a strong institutional-validation signal — investors in this group have strong security diligence processes.

Company-remained-independent endorsement

Per the official /products/onekey-pro page: "Adopted and invested by Coinbase Ventures and Binance Labs (YZi Labs) team while remaining fully independent." The key point on the company-relationship: OneKey remains fully independent of Coinbase and Binance. The investment is a beneficial signal of the security due-diligence done by these two flagship crypto-exchange venture arms — but neither Coinbase nor Binance has any operational / control / customer-data access to OneKey. This protects user privacy and sovereignty.

Air-Gap signing — fully offline signing path

OneKey Pro supports Air-Gap signing — the device can sign transactions offline without ever connecting to the internet for the signing operation. The user generates an unsigned transaction in the OneKey App, brings the unsigned transaction to the OneKey Pro (via the QR-code pairing or via the encrypted Bluetooth link), the OneKey Pro signs it offline, and the signed transaction is broadcast back to the connected host. This protects the private keys from any online attack vector (compacted host, malicious extension, browser-iframe injections).

Limitations

OneKey Pro is priced at $278 — at the premium end of consumer hardware wallets (more expensive than Ledger Stax $199 base configuration though similar to Ledger Stax + Keystone 3 Pro's $139 with accessories, and cheaper than Foundation Passport + Coldcard Mk4 with their bundles). Beginner-friendly but premium-positioned. The app ecosystem is broad but the dApp integration surface is currently smaller than Ledger Live's (1,000+ integrated dApps / apps in Ledger Live vs OneKey App's broader WalletConnect-only path for many dApps). For users who prioritize absolute breadth of integrated dApps without needing to scan WalletConnect QR codes manually, Ledger Nano X / Ledger Flex remains the de-facto-standard option. But for users who value highest-chip-tier security + wireless Qi2 charging + fingerprint-biometric unlock + Open Source + reproducible-builds, OneKey Pro is a uniquely-positioned premium alternative.

Hardware price — OneKey Pro is $278 USD

Per the official onekey.so /products/onekey-pro page (July 2026): OneKey Pro retails for $278 USD. This is the premium-tier of consumer hardware wallets — comparable to / slightly more than Keystone 3 Pro ($139 + accessories) and Cypherock X1 ($169), and cheaper than Foundation Passport + Coldcard Mk4 with their bundles at $300+. The $278 price includes the OneKey Pro hardware wallet device + the standard tamper-evident packaging + a USB-C cable + the basic starter accessories. Optional accessories (leather case, Qi2 wireless charging pad) sold separately.

Software is free — no subscription, no upgrade fees, no per-transaction fees

The OneKey App (iOS + Android + desktop) + the OneKey Browser Extension + the OneKey Web App (app.onekey.so) are all free to download, install, and use. There is no monthly / annual subscription, no per-transaction fee, no AUM fee on balances. Firmware updates (including the Bitcoin-Only firmware mode) are free and pushed via OTA. The Sign Guard scam-detection feature is included in the standard OneKey App at no extra cost. The OneKey Sifu 1-on-1 onboarding service is sold separately as a paid concierge service for users wanting personalized onboarding help.

Gas fees — paid to the chain, not OneKey

Gas / network fees on transactions are paid to the chain validators (Ethereum, Bitcoin, Solana, etc.) — not OneKey. OneKey never charges per-transaction fees; the device only signs the transactions the user creates. The user controls gas-fee settings via the OneKey App or via the connected dApp (MetaMask / OKX / Rabby / Sparrow).

No hidden swap fees

OneKey does not charge in-wallet swap fees on top of the underlying DEX / aggregator fees (because OneKey's in-app swap aggregator passes through the underlying DEX fee model without taking additional cut — like the Coinbase Wallet model rather than the MetaMask / Phantom / Rainbow model of taking an additional in-wallet service fee). This makes OneKey Pro one of the cost-optimal hardware wallets for active DeFi users who do many in-wallet swaps.

OneKey Sifu — optional paid concierge onboarding

The OneKey Sifu 1-on-1 onboarding service is sold as a separate paid concierge service (per the official homepage product block — "1-on-1 wallet setup with OneKey Experts"). Pricing for this service is shown on the OneKey Sifu product page during checkout; users who don't need concierge help can skip this entirely and use the standard free OneKey App + hardware wallet self-serve onboarding.

Per the official /products/onekey-pro page (July 2026): "1 Wallet. 100+ Chains. 30,000+ Coins." OneKey Pro supports 100+ blockchains and 30,000+ coins/tokens — one of the highest numbers of any consumer hardware wallet.

Major blockchains supported natively

• Bitcoin (BTC) — Taproot + SegWit + Legacy addresses; OneKey Pro supports the new Taproot (P2TR) address format per the homepage screenshot of the Clear Signing preview UI in July 2026 ("from bc1qrw...rz3p to Account 2 - Taproot")
• Ethereum (ETH mainnet) + all L2s (Optimism, Arbitrum, Base, Blast, Linea, Scroll, Polygon, BSC, Gnosis Chain, Celo, Fantom, Aurora) — full EVM decoding support per the official newsroom announcement "OneKey now fully supports EVM decoding"
• USDT (Tether) on all supported EVM chains + Tron + Solana
• Solana (SOL) — including SOL message signing per the newsroom announcement "Hardware Upgrade: SOL Message Signing"
• XRP (XRP Ledger) — native support (XRP Ledger signature + transaction signing on the OneKey Pro device)
• Tron (TRX) — native support (USDT-on-Tron transfers/signing)
• Cardano (ADA) + Polkadot (DOT) + Cosmos ecosystem (ATOM, OSMO, AKT) — native support
• Near, Sui, Aptos — supported
• Ton (TON) / Telegram ecosystem — supported
• Other long-tail chains — 30,000+ coins from 100+ chains, complete list onedisplayed in the OneKey App

Cross-software integration

Per the official /products/onekey-pro page: "Works with WalletConnect v2 and leading browser wallets like MetaMask, OKX, Rabby, and Sparrow." OneKey Pro connects natively with any WalletConnect-v2-compatible dApp via the WalletConnect standard. Per the official newsroom: Sparrow (the popular Bitcoin-only desktop wallet) now supports connecting OneKey Pro hardware wallets — letting Bitcoin maximalists pair OneKey Pro hardware with Sparrow software for full coin-control Bitcoin operations (comparable to the Sparrow + Coldcard or Sparrow + Foundation Passport Bitcoin-only setups). Per the newsroom: MetaMask now supports Air-Gap connection for OneKey hardware wallets — letting EVM users sign with OneKey Pro as an Air-Gap external signer.

NFT + DeFi support

Per the official /products/onekey-pro page: "NFTs and DeFi ready out of the box, connecting seamlessly with your favorite dApps." OneKey Pro's integrations with MetaMask, OKX, Rabby, and Sparrow cover the entire major-dApp ecosystem (Uniswap, Curve, Jupiter, PancakeSwap, Aave, Magic Eden, OpenSea, and more). OneKey App shows NFTs you own across all chains + lets you sign NFT transfer / sale transactions through the hardware device (Clear Signing decode gives you human-readable preview of the NFT and recipient address before you sign).

Staking support

Per the official newsroom (July 2026): "One-stop staking management page is now live" — OneKey App now supports native staking-on-hardware-wallet for major PoS chains (Ethereum, Solana, Cosmos ecosystem, Cardano, Polkadot, etc.). The all-in-one staking management page lets users stake, see validator, monitor rewards, and unstake directly from the hardware device — no need to expose the private keys to the staking dApp.
