Circle on March 20, 2026 announced Nanopayments, a system enabling gas-free USDC transfers down to $0.000001 by aggregating payments offchain and settling them onchain in batches. The non-custodial design uses signed payment authorizations, trusted execution environments, and the x402 protocol to provide instant merchant confirmations and scale high-frequency, machine-to-machine and AI-agent payments without per-transaction gas costs.
