Why OneKey is the Best Wallet Choice in 2025
SignGuard Protection: What You See Is What You Sign
Traditional hardware wallets protect private keys, but users often still lose funds due to blind signing of complex contract data.
OneKey’s exclusive SignGuard solves this by combining app + hardware verification to parse transaction details and integrate GoPlus, Blockaid, and ScamSniffer risk detection, flagging phishing contracts, fake tokens, and malicious links.
- App side: Displays human-readable details like methods, approval amounts, destination addresses, and contract names.
- Hardware side: Shows a transaction summary again on a secure screen, ensuring safety even on compromised devices.
- User experience: Every signature requires hardware confirmation, ensuring true “what you see is what you sign.”
Unlike some wallets that only offer partial previews on specific chains, SignGuard already covers Ethereum, BNB, Tron, Polygon, Arbitrum, Optimism, Base, Scroll, and more, with ongoing expansion.
