Circle launches Nanopayments testnet for tiny USDC payments
Circle launched its “Nanopayments” micro-payment USDC infrastructure on a testnet for AI agents and autonomous software. Built on Circle Gateway, it targets environments requiring fast, small-unit payments, including pay-per-call APIs, usage-based billing and machine-to-machine marketplaces. Circle said it solves sub-cent payment limits by batching transactions off-chain and settling them on-chain in bulk. The testnet supports multiple blockchains including Arbitrum, Base and Ethereum.
