Description
KeepKey is a physical hardware wallet for private key storage and transaction signing. Keys are generated and stored on the device during setup and never leave it. All transactions are reviewed on the built-in display and require physical button confirmation before signing. Firmware and hardware schematics are fully open source with deterministic, reproducible builds for independent verification. The device supports Bitcoin, Ethereum, Cosmos SDK chains, THORChain, Solana, XRP, TRON, TON, and various EVM networks, with cross-chain swaps via THORChain and Mayachain available through the companion desktop application.
