# Supported chains

MetaMask Agent Wallet supports all EVM chains. The authoritative list of preconfigured networks is the output of `mm chains list`.

## List supported chains[​](#list-supported-chains "Direct link to List supported chains")

```
mm chains list

```

For machine-readable output:

```
mm chains list --json

```

## Product coverage[​](#product-coverage "Direct link to Product coverage")

Agent Wallet supports all EVM-compatible chains. Pass any EIP-155 chain ID to `--chain-id` for signing, transfers, balances, and other wallet operations.

The tables below list every network from `mm chains list`. Availability varies by CLI version. Always confirm with `mm chains list` before scripting against a specific network.

## Per-chain balances[​](#per-chain-balances "Direct link to Per-chain balances")

Wallet balances and transfers are scoped to the chain you specify with `--chain-id`. Fund each chain separately, or bridge with `mm swap execute` before transferring.
