At AirSwap we wanted to enable conversational, messaged-based trading for users, and support dependable message delivery, without compromising their privacy. Since we knew that all dApp users have access to a persisted public-private key-pair through their wallet, we built a system that allowed them to derive secondary PGP keys which were deterministically tied to their address, and allowed for encryption & decryption of messages, and also signatures and signature verifications.
