Adjudicate

⚖️ Sources disagreed on Settlement time for x402 payments — S1 x402 batched settlements finalize in about 180 milliseconds on ARC testnet vs S2 x402 payment takes about 15 seconds to settle, similar to Ethereum L1 block time → trusted S1 (S1 provides specific benchmark data (median 178ms, p95 240ms) from thousands of calls on ARC testnet, while S2 offers a general statement without data. S1 is more specific and directly measures ARC network performance.)

AI agents can use nanopayments in USDC for real-time settlements on the ARC network by leveraging batching and sub-second finality. The ARC network provides sub-second finality (median 178ms, p95 240ms) for batched settlements , which is essential for real-time agent-to-agent payments. USDC settles peer-to-peer onchain in seconds and is programmable, enabling instant final settlement without counterparty risk . Nanopayments work by signing off-chain authorizations and settling them in batches, pushing the minimum economical payment to about $0.000001 . This batching approach aligns with ARC's submitBatch calls, allowing many micro-authorizations to settle together efficiently. Agents can thus automate real-time settlements by batching multiple USDC nanopayments into a single ARC transaction, achieving low-cost, instant finality. However, note that x402 payments as individual transactions may take ~15 seconds on Ethereum L1 , but on ARC, batched settlements are much faster .
