NeutralUsdc and other stablecoins are designed to maintain a peg to fiat currency (e.g., usd), so their price is intentionally stable. while this news significantly boosts their utility and potential for transaction volume, it does not directly influence their price beyond maintaining that stability. however, it strengthens their underlying value proposition and ecosystem trust.

Earlier this year, Coinbase engineers released the open source autonomous payments protocol x402, and more recently added a discovery layer for AI agents, something like a “Google for agents,” dubbed x402 Bazaar. In a note attached to the blogpost, Coinbase said x402 V2 expands the protocol beyond single-call, exact payments. “It adds wallet-based identity (skip repaying on every call), automatic API discovery, dynamic payment recipients, support for more chains and fiat via CAIP [Chain Agnostic Improvement Proposals for blockchain interoperability] standards, and a fully modular SDK for custom networks and schemes,” Coinbase said. It’s all aimed at making x402 “cleaner, more extensible, and future-proof, enabling unified payment models and wallet-based access for agents and humans alike,” the exchange said.
