【Blockchain Rhythm】The head of development at a leading exchange, erik.eth, recently revealed some big news— their x402 payment protocol has finally launched its V2 version. It’s worth noting that this protocol has undergone millions of real payment tests before being upgraded.

The biggest highlight of this update? It has thoroughly standardized the format of networks and assets. What does this mean? Servers can now accept stablecoins and even fiat currencies through the same interface on different chains—no more writing a bunch of cumbersome custom codes for each chain. For developers, this is truly a liberation of productivity.

Even more impressive, V2 introduces the concept of “extensions.” Simply put, clients, servers, and coordinators can now transmit more optional data, and it’s structured data. This immediately opens the doors for identity verification and multiple discovery mechanisms. The key is that developers can freely extend x402’s functionality without worrying about conflicts with the main standard—this design approach is indeed very forward-looking.

Hmm, is it true that one API can handle multiple chains? Is this upgrade reliable? --- Finally, no more writing so much messy custom code. Developers are saved. --- Standardization sounds good in theory, but will it actually work in practice? --- Millions of payment verifications have been conducted, so there’s definitely something there. But how should the extension features be priced? --- Wait, if identity verification is not done well, it might actually become a risk, right? --- The real challenge of multi-chain payments has never been the protocol itself, but whether there is enough liquidity. --- Another "epoch-making" upgrade—why do I feel a bit tired of hearing that? --- I want to ask how many projects in the ecosystem are actually using this stuff. Don’t tell me it’s just self-congratulation. --- Standardized formatting should have been done a long time ago. It’s a bit late now.
