KeepKey

1 min read
Pronunciation
[keep-kee]
Analogy
Like a secure safe with its own keypad and display that never exposes your PIN to the outside world.
Definition
A hardware wallet that stores private keys in a secure enclave, signing transactions offline and displaying details on an integrated screen to protect against malware and remote attacks.
Key Points Intro
KeepKey hardware wallets provide air‑gapped key storage and transaction confirmation for crypto custody.
Key Points

Secure enclave: Isolates private keys from host computer.

OLED display: Verifies addresses and amounts before signing.

PIN protection: Anti‑brute‑force with increasing delays.

Backup & recovery: 12‑word seed phrase exportable to other wallets.

Example
A user connects KeepKey to a desktop wallet app, reviews the transaction on KeepKey’s screen, and approves a Bitcoin transfer without exposing the key to the PC.
Technical Deep Dive
KeepKey’s microcontroller runs a custom firmware signed by the manufacturer. USB HID protocol transports APDU commands. The device enforces a secure boot chain and zeroizes memory after failed PIN attempts.
Security Warning
Fake or tampered devices can compromise keys; buy only from authorized resellers and verify firmware signatures.
Caveat
Less portable than mobile wallets; requires physical connection for each transaction.
