Celo integrates native MPP (Minimum Proof Protocol) support for AI agent USDC payments via x402 on shared gas-sponsored rails.
AI & Agents ·
Celo has integrated native support for the Machine Payments Protocol (MPP), an open HTTP 402 payment standard, enabling AI agents to settle USDC payments on the network. This development follows Celo's recent implementation of native x402 support, with both standards now operating through the same gas-sponsored facilitator. The integration allows sellers to charge USDC per request via the mppx SDK, with buyer agents incurring no gas fees as transactions route through shared infrastructure.
The addition addresses fragmentation in agentic payments, where x402 and MPP have each gained early adoption among different developer cohorts. By supporting both standards natively on a single facilitator, Celo enables sellers to accept payments from buyers using either standard without maintaining separate infrastructure. The mechanism uses EIP-3009's transferWithAuthorization to move USDC directly between parties while the facilitator sponsors gas without custodying funds.
Celo reported 33% agent wallet growth in the past month and hosts the majority of leading agents tracked on 8004scan.io. However, the current implementation supports only MPP's one-time charge intent model; session and subscription intents remain unavailable on the EVM path. Developer documentation for Celo-native MPP is available through the project's build resources.
