answer context
How does Tollgate's FeeRouter prove a citation payout with an on-chain receipt?
Tollgate's FeeRouter proves a citation payout with an on-chain receipt by emitting an evidence receipt that is hash-chained into a tamper-evident ledger each time a payout occurs. The FeeRouter contract routes USDC through an on-chain split keyed to the creator's wallet, and this payout transaction generates a cryptographic receipt linked into a ledger structure, creating an auditable chain of evidence for each citation payment.

Explains x402 settlement on Arc with EIP-3009 USDC authorization and verifiable on-chain transactions. Essential context for understanding how FeeRouter payouts are proven on-chain.Seed/demo content from Payments Protocol Notes. Title: x402 Settlement Schemes on Arc. Excerpt: x402 turns HTTP 402 into a real payment step: a resource returns payment requirements, the client signs an EIP-3009 USDC authorization, and the server settles it. The 'exact' scheme settles that authorization directly on Arc as a single USDC transfer, so the reader's debit is a verifiable on-chain transaction. The Circle Gateway-batched scheme instead pools many signed authorizations for gasless sub-cent settlement, referenced by a Gateway payment id rather than one Arc tx.
