# Supported networks

> Blockchain networks supported for USDC payments.

AgentCash pays endpoints in USDC across a small, curated set of networks.

## Networks

| Network    | CAIP-2 identifier                         | Type   | Status    |
| ---------- | ----------------------------------------- | ------ | --------- |
| **Base**   | `eip155:8453`                             | EVM    | Default   |
| **Solana** | `solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` | Solana | Supported |
| Tempo      | `eip155:4217`                             | EVM    | Testnet   |

Base is the default for payments. Most endpoints accept USDC on Base and transaction costs are minimal. Solana support is available for endpoints that prefer it.

## Addresses

Your wallet holds two distinct addresses:

* **EVM address** — one Ethereum-style address covers every supported EVM network (Base, Tempo).
* **Solana address** — a separate Solana keypair for USDC payments on Solana.

Run `npx agentcash accounts` (or the [`list_accounts`](/tools/list-accounts) MCP tool) to see each network's address, balance, and deposit link.

## Payment network selection

The endpoint decides which network to use. The OpenAPI `x-payment-info` block or the runtime `402` response declares the accepted networks and protocols. AgentCash matches that against your wallet and pays on the correct chain automatically. You can override with `--payment-network` on the CLI or the `paymentNetwork` field on the MCP [`fetch`](/tools/fetch) tool.
