The x402 ecosystem
A vendor-neutral map of protocol roles, SDKs, facilitators and payment networks around x402.
Slovenská verzia →Start with the protocol
The open x402 Foundation repository is the source of truth for specifications, reference SDKs and current payment schemes.
Evaluate combinations, not logos
An integration supports a concrete combination of protocol version, scheme, network, asset, SDK and facilitator. “Supports x402” is not precise enough for a production decision.
| Layer | Responsibility | Evaluation question |
|---|---|---|
| Client SDK | Builds and attaches payment payloads | Does it support our scheme and network? |
| Server middleware | Prices and protects resources | Can policy be configured per route? |
| Facilitator | Verifies and settles payments | What is the trust and availability model? |
| Wallet | Signs client authorization | Does it enforce budgets and scoped permissions? |
