# Supported Networks — Every EVM Chain

> AgentaOS signs on Ethereum, Base, Arbitrum, Optimism, Polygon, and every EVM-compatible chain. Bitcoin and Solana support planned.

# Supported Networks

AgentaOS signs transactions on any EVM chain.

## Supported Chains

| Network          | Chain ID   | Status    |
| ---------------- | ---------- | --------- |
| Ethereum Mainnet | `1`        | Supported |
| Base             | `8453`     | Supported |
| Arbitrum One     | `42161`    | Supported |
| Optimism         | `10`       | Supported |
| Polygon          | `137`      | Supported |
| Sepolia          | `11155111` | Supported |
| Base Sepolia     | `84532`    | Supported |
| Arbitrum Sepolia | `421614`   | Supported |

<Info>
  All EVM-compatible chains work out of the box. AgentaOS uses a pluggable chain architecture — if it speaks EVM, it signs.

## How It Works

Agenta doesn't care which chain you target. The signing protocol operates on raw transaction hashes. The chain adapter handles serialization, gas estimation, and broadcasting.

Pick a network when you create a signer:

```bash theme={null}
agenta sub create --name my-agent --json
```

Or specify it per transaction:

```bash theme={null}
agenta send 0xRecipient 0.01 --network arbitrum
```

***

## Testnets

Start with testnets. Every mainnet chain has a testnet counterpart.

<Tip>
  Use Base Sepolia for development. Fastest block times. Free faucet ETH from [Alchemy](https://www.alchemy.com/faucets/base-sepolia).
