x402 vs MPP
| x402 | MPP | |
|---|---|---|
| author / steward | Coinbase → Linux Foundation | Stripe + Tempo |
| mechanism | HTTP 402 challenge, pay-per-request | IETF Payment HTTP auth, session-based |
| rails | USDC (Base, Solana, more) | USDC on Tempo, card via Visa, Lightning |
| accounts | none — wallet is identity | Stripe compliance stack built in |
| transports | HTTP | HTTP, MCP, JSON-RPC |
| compatibility | MPP is backwards-compatible with x402 — MPP clients can pay x402 services, so x402-first services reach both worlds | |
OpenSpender + MPP
The OpenSpender gateway ships x402-first (reachable by MPP clients via backwards compatibility). Native MPP endpoints — session payments, card rails, MCP transport — are on the roadmap. Protocol sources: mpp.dev · specifications.
