Coinbase has launched an updated version of its stablecoin-based payments protocol for AI agents, called x402 V2. This new version enhances the protocol, making it easier for developers to integrate autonomous payment systems into existing services. Key features include wallet-based identity, automatic API discovery, dynamic payment recipients, and broader support for various blockchain networks and fiat currencies through CAIP standards. The design is modular, allowing for more flexibility and customization. Earlier this year, Coinbase introduced the original x402 protocol and a discovery layer for AI agents named x402 Bazaar. These developments aim to streamline the payment process by reducing the need for repetitive calls when making payments. The focus is on creating a cleaner and more adaptable system that can accommodate both AI agents and human users. This evolution reflects Coinbase's strategy to position itself at the forefront of blockchain interoperability and decentralized finance. In a related note, Tomasz Stańczak, co-executive director of the Ethereum Foundation, will step down at the end of the month. He has been in the role since the departure of Aya Miyaguchi in 2025. Bastian Aue will take over as co-executive director alongside Hsiao-Wei Wang, continuing the foundation's leadership amid ongoing scrutiny about its effectiveness in nurturing the Ethereum ecosystem.
