Company profile
researched Aug 2026OneKey builds cryptocurrency hardware wallets and accompanying self-custody software. Its hardware line includes OneKey Pro, the Classic 1S (with built-in battery, $99), the battery-free Classic 1S Pure and a Bitcoin-only Classic 1S Pure variant ($79), plus accessories such as the KeyTag titanium seed backup kit and the OneKey Lite encrypted backup card. A companion OneKey App runs on macOS, Windows, Linux, iOS, Android and Chrome, and can be used either paired with a hardware device or standalone as a hot wallet; a browser extension and a web app are also offered. The company additionally sells "Sifu," a paid one-on-one wallet setup service with OneKey staff.
The software covers buying and selling crypto (card, bank transfer, Apple Pay, Google Pay), sending and receiving, swaps with automated routing and pre-confirmation fee display, staking with APY and risk display, perpetual futures trading without KYC, keyless (seedless) wallet options, market data and dApp connectivity across 100+ networks and 30,000+ coins and tokens. Security features include the SignGuard transaction-analysis system built by OneKey's Anzen Security Lab, transaction previews and clear signing, a dApp-blocking in-app browser, MEV protection, hidden wallets, app lock, trusted contacts and similar-address detection, with risk data sourced from GoPlus and Blockaid.
As of the 2022 Series A the company employed about 30 people and said it intended to stay lean and prioritize long-term profitability, with no plans for a native token at that time.
Founding story
Sources state OneKey was founded in 2020; Yishi Wang is identified as a core contributor and public spokesperson for the company. No further detail on the founding circumstances is provided in the sources.
Business model
OneKey sells consumer hardware wallet devices and accessories directly through its online shop (with free global shipping over $89, exceptions applying) while distributing its wallet software free of charge. The app layer adds transactional features β swaps with disclosed fees, fiat on-ramps, staking and perpetual futures with a referral program β and the company also offers a paid onboarding service (Sifu). Sources do not detail the economics of the software features.
Primary disclosed revenue source is hardware sales (e.g., OneKey Classic 1S at $99, Classic 1S Pure at $79) plus a paid one-on-one setup service; the app itself is free and non-custodial. Sources do not state fee levels for in-app swaps, trading or staking.
Traction
At the 2022 Series A, the company said it had taken custody of billions of dollars in crypto assets based on incomplete third-party statistics, was growing rapidly, and had around 30 employees. Current site claims include support for 100+ chains and 30,000+ coins and tokens and over one million scams blocked per year by SignGuard. Published customer reviews describe fast shipping and device usability. Sources provide no revenue, unit-sales or user-count figures.
Latest developments
The current site highlights the Classic 1S Pure BTC-Only Edition, the OneKey Pro and Classic 1S devices, the KeyTag and (as "notify me") OneKey Lite backup products, and the Sifu setup service. Recent newsroom items cover full EVM decoding support, a hardware upgrade enabling Solana message signing, a one-stop staking management page, and integrations allowing Sparrow and MetaMask (air-gap) to connect to OneKey hardware. The app has expanded beyond wallet functions into swaps, perpetual futures and trading of "crypto, stocks, and more."
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company describes itself as the only hardware wallet backed by both Coinbase Ventures and YZi Labs (formerly Binance Labs) while remaining independent, and as the only hardware wallet officially co-branded and adopted by Binance, OKX, Bybit and Bitget. At the time of its Series A it claimed to be the number one hardware wallet in the Eastern Hemisphere and to have been listed No.1 on BTC.COM. It positions itself against wallets such as Ledger and Trezor on the basis of being 100% open source while using a certified secure chip.
Stated differentiators are full open-source, reproducible firmware and apps combined with a certified EAL 6+ secure element, independent SlowMist audits, no-KYC usage and no private data collection, support for user-supplied RPC endpoints, and a claim of zero losses since inception. The company also emphasizes dual backing by Coinbase Ventures and YZi Labs/Binance Labs and exchange co-branding as trust signals.
Technology
Devices use EAL 6+ certified secure element chips (Common Criteria / ISO/IEC 15408), with tamper-evident packaging, firmware attestation at first activation, PIN protection with data wipe after repeated failures and auto-wipe on detected intrusion such as firmware modification. Firmware and applications are stated to be fully open source and reproducible on GitHub, with independent audits by SlowMist and ISO/IEC 27001 certification claimed for the app. Software supports WalletConnect v2 and connections to third-party wallets including MetaMask (air-gapped), OKX, Rabby and Sparrow, custom RPC endpoints, EVM transaction decoding and Solana message signing.
Go-to-market
Direct-to-consumer online sales through the OneKey shop, with global shipping, alongside distribution via Amazon (referenced by a customer review) and co-branded exchange editions. Free apps and a browser extension act as an acquisition funnel for hardware, supported by a newsroom, newsletter, X/Twitter presence, community gifting/bulk offers, a help center and live customer support, plus a perpetuals referral program.
Retail cryptocurrency holders who want self-custody, including users who prefer open-source and auditable devices, Bitcoin-only holders, DeFi and NFT users, and traders wanting non-KYC swap and perpetuals access from a wallet. Press coverage notes adoption among employees of other crypto firms, and the company markets co-branded devices distributed with major exchanges.
Geography
Headquartered in Hong Kong per press coverage of the Series A; the shop ships globally with free shipping over $89, and apps are distributed for macOS, Windows, Linux, iOS, Android and Chrome.
History
Founded in 2020, OneKey announced a roughly $20 million Series A in September 2022 led by Dragonfly and Ribbit Capital, alongside a separate "small funding" round involving IOSG Ventures. In October 2022 it published items on being listed No.1 on BTC.COM and on establishing its in-house hardware security lab, Anzen. Subsequent product milestones publicized in its newsroom include full EVM decoding, Solana message signing on hardware, a consolidated staking management page, MetaMask air-gap and Sparrow connectivity, the Sifu onboarding service, and the Classic 1S Pure and BTC-only editions.
Risks & controversies
Sources contain no reports of incidents, litigation or regulatory action against OneKey. Notable caveats: several claims (zero losses since inception, number one hardware wallet in the Eastern Hemisphere, billions in assets under custody, 1M+ scams blocked annually) are company self-assertions, some based on "incomplete 3rd-party statistics." The offering of non-KYC trading and perpetual futures may carry regulatory exposure, though no source addresses this. A customer review references a data breach at competitor Ledger, not at OneKey.
