Overview
- The open-source protocol extends single-call stablecoin payments into wallet-based sessions that grant returning users or agents access without repeat on-chain charges.
- A standardized format aligned with CAIP lets one interface route payments across Base and Solana as well as ACH and card networks.
- A modular, plug-in SDK separates clients, servers and facilitators so developers can add chains, assets or schemes without altering the core specification.
- New Discovery features expose service metadata so facilitators can index offerings and AI agents can find pricing and initiate payments automatically.
- Additional capabilities include dynamic recipients, lifecycle hooks and multi-facilitator support to enable automated, usage-based billing at internet scale.
