x402 HTTP micropayments go live on Canton MainNet via FTP Tech
CantonNews (July 10, 2026): FTP Tech shipped the x402 payment standard on Canton MainNet—HTTP APIs can charge per request via the 402 Payment Required flow, with each payment settling on-ledger in Canton Coin. The stack comprises a non-custodial facilitator (verifies settlement without holding buyer/seller funds), a client SDK, and middleware gating resource servers. FTP Tech also offers a Canton Agent Wallet so AI agents hold self-custody CC and pay for x402-gated APIs from their own balance while the facilitator submits transactions and pays gas. Integration is open source under Apache-2.0 for API providers, agent builders, and institutions needing auditable on-ledger settlement.
