§ IIThe reading1 cited

Moderateconfidence— 1 source cited

Stablecoins like USDC reduce settlement risk for autonomous buyers through several mechanisms: - Near-instant settlement: USDC settles peer-to-peer onchain in seconds, removing multi-day delays typical of card networks and ACH, thus reducing time-based risks . - Stable value: As a dollar stablecoin, USDC provides a stable unit of account, eliminating volatility risk during the settlement window and enabling rational spending decisions . - Programmability and finality: Instant final settlement means an agent can pay and immediately receive a resource without counterparty risk, and smart contracts can automate conditional payments, reducing reliance on intermediaries and manual reconciliation .
