Why KeepKey
Your Crypto Deserves Better Than a Black Box
Most hardware wallets ask you to trust them. KeepKey asks you to verify. Every line of firmware code, every circuit on the board — published on GitHub for anyone to audit.
Fully Open Source
Firmware AND hardware schematics on GitHub. Ledger publishes neither. Trezor publishes firmware only. KeepKey publishes everything.
Clear Signing
Auto-detects contract calls from public ABIs. No registry opt-in needed. Shows decoded transaction details on the device screen. Two-step confirmation for blind signing.
Built-in Swaps
Trade cross-chain directly from your wallet via THORChain, ShapeShift, and ChainFlip. No exchange account, no KYC. Your keys never leave the device.
All EVM Chains
Every EVM chain works via EIP-155. Add custom chains by chain ID — the same 'Add Network' as MetaMask but with hardware security. Ledger Live and Trezor Suite can't do this.
Scrambled PIN & Recovery
PIN entry uses a randomized grid — keyloggers capture nothing. Recovery uses scrambled cipher entry — your seed phrase never touches the keyboard.
Vault Desktop App
Free companion app for macOS, Windows, and Linux. Portfolio dashboard, cross-chain swaps, staking, activity tracking, and settings — all in one place.
Chain Support
Every Chain. No App Installs.
All chains available simultaneously from firmware. No storage limits. No switching between apps. Plus add any custom EVM chain yourself.

Trade From Your Wallet. Not an Exchange.
Swap between any supported chain directly from KeepKey Vault. ETH to BTC. AVAX to SOL. Your keys never leave the hardware device.

Security Model
Verify, Don't Trust
Your private keys are generated on the device and never leave it. Every transaction is signed on the KeepKey and displayed on the large OLED screen for verification before broadcast.
