Claim swept funds

Prove original ownership locally, then claim funds locked for the owner of the compromised payment credential.

Claim funds Lock or donate funds

For rescuers, white-hats, and donors

Mainnet proof pathBuilt for Cardano mainnet

Lock / Donate creates an original-owner-only UTxO

Use it after sweeping from compromised credentials, or to donate in a way the attacker cannot claim without the master-derived proof.

Open lock / donate flow

Proofs stay narrow

The proof establishes derivability of the compromised 28-byte payment key credential. It does not ask you to trust a hosted server with your recovery phrase or master private key.
