How It Works
Hedera message signing verification
§ 01
Create Challenge
Call our API with the Hedera account ID. We generate a unique message for the user to sign.
§ 02
User Signs Message
User signs the challenge message with their wallet (HashPack, Blade, etc.). No transaction needed.
§ 03
Proof Generated
We verify the signature and return a proof token confirming wallet control.
