KeepKey
Take control of your crypto
KeepKey is a hardware wallet for offline private key storage and transaction signing. Keys are generated and held on the device during setup and never leave it, with every transaction reviewed on the built-in display and confirmed with a physical button before signing. The firmware and hardware schematics are open source with reproducible builds, allowing independent verification of the code and design running on the device. It natively signs Bitcoin and related forks, Ethereum and other EVM chains, Ripple, Cosmos, THORChain, Maya Protocol, Solana, TRON, and TON, and supports built-in decentralized cross-chain swaps sourced from multiple liquidity protocols.
