Payment Options
Payment rails for developers, wallets, and autonomous agents.
| Method | Best For | Settlement |
|---|---|---|
| USDC on-chain | Developers with wallets | Immediate, per-request |
| x402 | Autonomous agents | Immediate, per-request |
| MPP (Tempo) | High-frequency agents | Session-based micro-payments |
| Fiat onramps | Buyers funding a Base wallet from fiat | Funds arrive as Base USDC, then normal per-request settlement applies |
All methods settle to sellers in USDC on Base. The buyer's funding method doesn't affect the seller experience.
- USDC On-Chain — the standard flow for wallet users
- x402 Protocol — HTTP 402-based per-request payments
- MPP (Tempo) — Machine Payments Protocol
- ACP (Virtuals) — agent-to-agent commerce with on-chain escrow; internal roadmap only until a public guide exists
- Fiat Onramps — Coinbase Onramp, Peer/ZKP2P, MoonPay, and direct Base USDC transfers
