Why not just use L2 for attribution?

Even L2s cost $0.01-$0.10. For AI inference or API calls costing $0.0001, L2 is too expensive. x402 consolidates thousands of calls into ONE on-chain transaction.

Yes. The user locks funds. The provider cannot take more than signed. The user can withdraw funds after a timeout if the provider disappears.

ERC-8021 is a standardized method for attributing transactions to applications using x402 protocol logic and structured data suffixes.
