How does Tollgate prove paid citations with x402 receipts on Arc?
Tollgate proves paid citations with x402 receipts on Arc through a multi-layer verification system: (1) Circle Gateway batches signed EIP-3009 authorizations to enable x402 payments at sub-cent values without per-payment gas overhead. (2) Arc provides stablecoin-native settlement with USDC, sub-second finality, and app kits for payment workflows. (3) CitePay Markets implements the proof layer—every PAY decision generates an on-chain receipt with SHA-256 evidence hash and content integrity proof, settled via Circle Gateway x402 on Arc Testnet. (4) CitePay's on-chain audit page reads directly from Arc RPC with no database, showing DCW wallet balance, transaction count, and USDC paid to creators—pure chain verification. (5) Receipt hashes are tied to the answer that reused the work, making source payment automatic, visible to creators, and cryptographically verifiable.
