§ IIThe reading1 cited

Moderateconfidence— 1 source cited

Stablecoins enable fast and low-cost settlement for machine-to-machine payments, as USDC settles peer-to-peer onchain in seconds, removing counterparty risk and multi-day delays . They provide price stability, giving autonomous agents a stable unit of account to reason about budgets and make rational spending decisions . Stablecoins are also programmable, allowing smart contracts to automate M2M commerce . While micropayments are a related benefit, the sources only directly discuss fast settlement enabling instant transfer of value; explicit micropayment support is not covered in the provided text.
