Circle has introduced gas-free USDC Nanopayments on the mainnet, spanning 11 blockchains. This initiative is aimed at AI agents, APIs, and machine-driven commerce. According to NS3.AI, Circle stated that the system facilitates transfers as small as $0.000001, offering instant verification and batched on-chain settlement. The Nanopayments system expands x402 flows, which have processed over $100 million since their launch earlier this year.
