U.S.-listed cryptocurrency exchange Coinbase (COIN) has released the latest version of its stablecoin-based payments protocol for AI agents, aiming to make the autonomous payments system easier to integrate and extend, the company said in a blog post Thursday.

The upgraded framework, x402 V2, shifts the tool from the question of “what does it actually do” to “which existing services can we plug it into next,” a Coinbase representative said in an email. The new version offers a modular design that lets developers combine payments, enable secure wallet access and add new features more seamlessly, the company said.
