Cutting-Edge Features Enhancing User Experience
OneKey continues to lead through continuous innovation. Recent updates have significantly expanded functionality:
Full EVM Decoding Support

SOL Message Signing Upgrade
With growing interest in the Solana ecosystem, OneKey has upgraded its firmware to support SOL message signing directly on-device. This enables secure interactions with Solana-based dApps without exposing private keys.
One-Stop Staking Management
Staking your assets has never been easier. The newly launched staking management page provides a unified dashboard to monitor rewards, delegate stakes, and track performance across multiple chains — all from within the OneKey app.

- Sparrow Wallet: Full compatibility enables advanced Bitcoin users to leverage multisig and CoinJoin features securely.
These integrations mean you can enjoy the flexibility of software wallets with the ironclad security of hardware signing.
Backed by Industry Leaders
OneKey is the only hardware wallet backed by both YZi Labs (formerly Binance Labs) and Coinbase Ventures — two of the most influential forces in blockchain innovation. This dual endorsement speaks volumes about its technological excellence, long-term vision, and commitment to user security.
Their investment fuels ongoing R&D, ensuring OneKey stays ahead of emerging threats and adapts quickly to changes in the DeFi space.
Why Hardware Wallets Matter in 2025
As decentralized applications grow more complex, so do the risks. Phishing attacks, fake dApps, and social engineering scams are on the rise. Software wallets alone cannot protect against these threats — they lack true isolation.
A hardware wallet acts as a physical barrier between your keys and the internet. Even if your computer is compromised, your funds remain safe because transactions must be manually confirmed on-device.
For anyone serious about crypto ownership, self-custody via a hardware wallet isn't optional — it's essential.
