Special devices for storing private keys (incl coins - e.g. [[Crypto-Currency]]).
- Secure in hardware (can only perform the required key storage functions)
- airgapped / disconnected, so unavailable for attackers
- many require transaction confirmation by physically pressing a button on the device
- encrypted with a pin, meaning they are unusable when phycially stolen
- can support multiple cryptocurrencies
- software often open source, so can be independently analysed
