What is OneKey wallet?

OneKey wallet is a self-custody crypto wallet that combines a software app with optional hardware devices. The company behind it, ONEKEY LIMITED, says it has operated since 2019 and describes itself as an open-source hardware wallet project. You hold your own keys, so there is no account to log into and no company that can reset your access.

What can you do with the OneKey wallet app?

The OneKey app works as a standalone hot wallet or as the companion app for a OneKey device. As of November 2026, OneKey lists apps for iOS and Android, desktop versions for macOS, Windows and Linux, and a browser extension for Chrome. The app handles sending and receiving, portfolio tracking, built-in token swaps, multiple wallets and accounts, and connections to decentralized apps.

OneKey says the wallet supports more than 5,000 coins and tokens, including Bitcoin, Ethereum, Solana and EVM networks such as BNB Chain, Arbitrum and Polygon. When you connect to a dapp, the app parses the transaction and flags risks it detects. It also publishes migration guides for people moving from wallets such as MetaMask, Phantom and Trust Wallet.

How does the OneKey hardware wallet work?

A OneKey device generates and stores your private keys inside a secure element chip, and each transaction must be confirmed on the device itself. OneKey's product line as of November 2026 includes the Classic 1S, a battery-free Classic 1S Pure, and the Pro, which has a color touchscreen, fingerprint unlock and the option to sign transactions by QR code without a cable. It also sells Lite, an NFC card for backing up a recovery phrase.

OneKey says most of its devices use secure element chips certified to EAL 6+, and the PIN is entered on the device. It supports an optional BIP39 passphrase for hidden wallets, which is explained in our guide to the seed phrase passphrase.

What is in the OneKey wallet GitHub repositories?

OneKey's GitHub organization, OneKeyHQ, hosts dozens of public repositories. The largest, app-monorepo, holds the code for the desktop, mobile, web and extension apps. Separate repositories hold firmware for the Pro, the Classic 1S and a newer device line, plus a JavaScript SDK for talking to the hardware.

The app-monorepo README states the code is licensed under the OneKey Standard Source License (O-SSL), with a free Community Edition for individuals. That is a company-written license rather than a standard open-source license such as MIT, so anyone who plans to reuse the code should read the license text. OneKey says its builds can be reproduced from source and checked against official releases, and it names SlowMist among the firms that have audited it. Security bugs are reported privately through its bug bounty process rather than public GitHub issues.
