Why Choose a OneKey Hardware Wallet?
Hardware wallets are widely regarded as the gold standard for protecting private keys and digital assets. Unlike software wallets that remain connected to the internet, hardware wallets store keys offline—shielding them from online threats like hacking, phishing, and malware.
OneKey takes this security model further by combining robust hardware design with intuitive software experiences. Whether you're managing Bitcoin, Ethereum, or emerging altcoins, OneKey ensures your assets stay safe while remaining accessible when needed.
Security Built into Every Layer
The core philosophy behind OneKey is simple: secure hardware protects software. Each device is engineered with military-grade components, secure element chips, and open-source firmware to ensure transparency and trust.
With features like air-gapped transaction signing and support for advanced cryptographic protocols, OneKey minimizes attack surfaces and gives users full control over their funds—without relying on third parties.

Advanced Features That Set OneKey Apart
Full EVM Parsing Support
OneKey now fully supports Ethereum Virtual Machine (EVM) parsing, allowing users to view detailed transaction data before signing. This prevents malicious contracts from tricking users into approving unauthorized transfers—a common vector for DeFi scams.
By decoding complex smart contract interactions into human-readable formats, OneKey empowers users to make informed decisions with every transaction.
SOL Raw Message Signing
For Solana enthusiasts, OneKey has added support for SOL raw message signing. This enables secure authentication and interaction with Solana-based dApps while keeping private keys offline. As the Solana ecosystem grows, this feature ensures early adopters have a secure gateway to participate in new projects.
Unified Staking Dashboard
Staking has become a cornerstone of decentralized finance, offering passive income opportunities across multiple blockchains. OneKey’s all-in-one staking management page allows users to monitor, delegate, and claim rewards from various networks—all within a single interface.
No more juggling between different platforms or risking exposure by importing keys elsewhere. With integrated staking, users maintain full custody while earning yield.
Seamless Integration with Leading Crypto Tools
OneKey continues to expand its ecosystem compatibility, ensuring smooth interoperability with popular wallets and tools:
- Sparrow Wallet: Now supports direct linking to OneKey hardware devices, enabling enhanced Bitcoin privacy and transaction control.
- MetaMask: Users can connect MetaMask via air-gap signing, meaning transactions are signed offline and transferred securely using QR codes—eliminating internet exposure entirely.
These integrations reflect OneKey’s commitment to bridging the gap between high security and everyday usability.

Such support not only validates the product but also ensures ongoing development, regular firmware updates, and alignment with emerging blockchain standards.
