Alzymologist Oy Lab

Kampela is a air-gapped hardware key manager and signer device for blockchain systems. It is a small card-shaped device (ideally comparable to a credit card form factor, to be carried in a wallet when needed) that accepts data through unidirectional NFC port and shows output on a monochrome electronic paper screen. It has cryptographic strongbox — which only stores private keys (after initial import) and performs all signing operations on-chip.

Kampela is is designed to leverage the most out of modern crypto chips and drastically reduce signer’s attack surface: no mobile OS, not extra platform features, no unexpected communication methods or airplane mode to take care of.

Kampela is not a wallet! It is a signing tool, it is not able to track on-chain balances, validate things over chain-provided information or generate transactions on itself.
