Arc X402

by APEX Arc x402 payment history in Markets & finance

x402 APIPassing, checked 3 h ago

Every signed x402-style payment on Arc since launch, read from the chain (plain USDC transfers carry no marker of what they paid for and are not counted): each EIP-3009 authorization spent on Arc USDC (AuthorizationUsed on 0x3600..., joined to the transfer it moved, in either of the two forms Arc logs it) and every Circle Gateway batch (net flows per address, decoded from submitBatch).
