One seller wallet, each chain read on its own. We never send a payment, so we never observe what a paid call returns. Unknown means we hold no reading, not that anything failed.

Claim this merchant

Sign a message from the payout address GDNJXCKW…FJWWRL to claim this page. Claiming proves control of the payout key. It says nothing about the service behind the address, and it does not change how this merchant is ranked. No email, no account: the signature is the whole credential, and signing a message costs no gas and moves nothing.

The payment ledger covers Base only for now, so it is not offered for Stellar.
