Weekend thoughts. Missed the x402 cat minting this morning, but later bought a few on the secondary market, and the overall visual effect is pretty good. I’ve always been quite interested in the x402 payment protocol behind this project.

Recently, I saw someone summarize the core logic of the protocol: through the EIP7702 upgrade plan, the seller’s EOA account can directly embed payment logic. This design is clever—it can operate in an environment with no Gas consumption and minimizes trust costs. At the same time, it’s compatible with universal token standards like ERC20 Permit, so there’s no need to create a whole new system just for payments.

This approach does represent an improvement in on-chain payment experience.
