The OneKey Classic 1S is a secure, open-source hardware wallet that builds on the success of the original OneKey Classic. Released in 2024, the 1S version improves upon its predecessor with added air-gap support, stronger encryption, and enhanced device usability—making it a powerful contender in the cold wallet space.
🔐 Security & Technology
OneKey Classic 1S uses a secure element chip to store private keys offline, never exposing them to internet-connected environments. It supports air-gapped operations, meaning it can be operated completely offline using QR codes for transaction signing.
Security Features:
- Air-gapped QR-code signing
- Open-source firmware audited by third parties
- Secure Element (SE) chip
- Self-destruct PIN and passphrase support
- Firmware signature verification
This wallet is ideal for long-term holders, developers, and crypto privacy enthusiasts.
🖥️ Display & User Experience
The wallet features a 240×240 px color display, offering a clean interface to verify transaction details before approval. It has physical buttons for safe manual navigation and on-device signing, reducing risks of malware-injected clicks from external devices.
📦 Supported Assets
OneKey Classic 1S supports:
- Bitcoin, Ethereum, and ERC-20 tokens
- Solana, Polkadot, Cosmos, Dogecoin, TRON, Avalanche, and more
- NFTs (via third-party integrations like MetaMask)

🔌 Connectivity & Compatibility
Connectivity:
