#跨链基础设施与互操作 Cross-chain payments have finally been made more elegant! The release of x402 V2 has shown me the direction of Web3 infrastructure evolution—moving from isolated points to a system, from complexity to simplicity.

The most annoying part of cross-chain interactions used to be repeated authorizations, fragmented payment processes, and chains ignoring each other like strangers. Now, x402 eliminates the need for repeated payments through wallet identity mechanisms, supports automatic API discovery, and dynamically adjusts recipients. Isn’t this building a true payment infrastructure? Just like upgrading from isolated roads to a connected high-speed network.

Even better is the modular SDK design—which means developers can flexibly adapt according to their needs, no longer bound by protocols. This design philosophy is exactly what Web3 should be: flexible, open, and composable. Plus, with support for CAIP standard extensions to connect more chains and fiat channels, x402 V2 is actively practicing true interoperability.

The future of decentralization requires such an infrastructure layer—making cross-chain as natural and convenient as using electricity, reducing friction for developers and users. This is the essential path for Web3 to move from dream to reality. Looking forward to more projects building on such standardized protocols, truly enabling the ecosystem to flow.
