ChainCatcher 消息，据 The Block 报道，由 Coinbase 孵化、专为人工智能（AI）代理打造的开源支付协议 x402 在推出约六个月后，正推出一项重大升级。

x402 V2 本质上将原本简单的单次调用支付系统转变为一个成熟的、面向互联网的统一支付层。V2 版本是一系列后端改进，旨在使创建可定制的支付流程、更好的钱包和身份功能以及支持“传统支付系统”等变得更加容易。

V2 版本最大的升级在于统一了 x402 的支付接口。x402 V2 规范了协议中网络和资产的识别方式，“创建了一种可在不同区块链和传统支付系统上通用的单一支付格式”。这意味着 x402 将“默认支持多链”，能够支持 Base 或 Solana 等其他区块链的原生代币，而无需定制逻辑。此外，该系统还与“传统支付系统”兼容，如 ACH 和银行卡网络。

更新后的系统还推出了动态“payTo”路由功能，可支持基于使用量的计费、订阅、预付支付和多步骤交易等支付流程。开发者还可以注入“lifecycle hooks”，用于条件工具或指标监控，并创建更具定制化的支付墙。
