How do Forum covenant mandates enforce agent spend control on Arc?
Forum covenant mandates enforce agent spend control on Arc through enforceable budget bounds and receipt publication. Forum-style mandates bind an agent's budget, publish cryptographic receipts of all transactions, and make spend controls enforceable rather than advisory. This works on Arc because Arc is designed for stablecoin-native settlement with USDC, sub-second finality, and app kits for payment workflows. When combined with x402 payment protocols (which enable sub-cent nanopayments), agents can make granular, auditable purchases while staying within their mandated budget envelope. The receipts are published on-chain or in a verifiable ledger, making violations transparent and enforceable by the protocol or governing entity.
