What does Tollgate use to prove paid citations with on-chain receipts on Arc?
Tollgate uses USDC on-chain receipts on Arc to prove paid citations. The system leverages Arc's stablecoin-native settlement with USDC gas and sub-second finality, combined with x402 payment protocols that enable sub-cent value transactions. Receipt hashes are published on-chain, making source payments visible, automatic, and tied to the specific answers that reused the work.
