One passkey, one encryption address.
Your device turns your passkey into an encryption key and posts only its public half to a register on Monad. Anyone can look up your address and seal a note to it. Only your passkey opens it, on any device the passkey syncs to.
ExampleWhat your card will show once your key is posted. This one is an example made by the SDK from a labelled string: not yours, and not on chain.
What happens when you press it
Derive
Your passkey’s PRF output becomes an X25519 key on this device. The secret half is never stored and never leaves it.
createEncryptionAddress()Post
The same passkey derives an account, and the account posts the public half to the register on Monad as epoch 1. A new account holds no MON, so the Letterlock gas drip pays for this first post.
publish(pk, epoch)Receive
Any app or agent looks you up and seals to that key without asking you. Opening it takes your passkey.
