Driving adoption of blockchain payments requires standardization. That's why some leading platforms collaborated with major infrastructure providers to roll out x402—a groundbreaking open standard for on-chain payments.

Here's the interesting part: the name draws inspiration from a rarely-seen HTTP status code—402 Payment Required. It mirrors the structure of the familiar 404 error, but with a payments twist.

What's the vision behind x402? Pretty straightforward actually:

👉 Enable seamless, protocol-level payment mechanisms across web services
👉 Create interoperability between traditional internet infrastructure and blockchain-based transactions
👉 Standardize how platforms handle micropayments and value exchange on-chain

This move signals a broader shift: the crypto ecosystem isn't just talking about decentralized finance anymore—it's actively building the technical plumbing to make blockchain payments as native to the web as HTTP itself.
