## Supported networks and tokens

x402 is available on the following networks:

| Network | Supported |
|---------|-----------|
| **Base** | USDC, EURC, other ERC-20s |
| **Ethereum** | USDC, EURC, other ERC-20s |
| **Arbitrum** | USDC, EURC, other ERC-20s |
| **Polygon** | USDC, EURC, other ERC-20s |
| **Solana** | USDC |

Payments are made in **USDC** using [EIP-3009](https://eips.ethereum.org/EIPS/eip-3009) (permit-and-transfer in a single transaction), with **EURC** and other ERC-20 tokens supported via [Permit2](https://docs.uniswap.org/contracts/permit2/overview). On Solana, payments use native USDC SPL tokens.

Which networks and tokens a specific endpoint accepts is returned in the `PAYMENT-REQUIRED` header. Facilitators like [CDP](https://docs.cdp.coinbase.com/x402/network-support) may also restrict which networks they support.

<Note>
Your agent only needs a funded wallet on the network the API accepts. No bridging or multi-network setup required.
