# Supported chains

MetaMask Agent Wallet supports EVM chains configured in the Accounts API. The authoritative list for your CLI version 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

```

The JSON output includes per-network fields such as `shieldSupported` and `guardSupported`. `shieldSupported` indicates whether [Transaction Shield](https://support.metamask.io/manage-crypto/transactions/transaction-shield/)coverage applies on that network. All networks listed below support Guard Mode (`guardSupported: true`).

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

Pass any supported chain ID to `--chain-id` for signing, transfers, balances, and other wallet operations. Availability varies by CLI version. Always confirm with `mm chains list` before scripting against a specific network.

The tables below reflect the current preconfigured network list. The `mm chains list` output also includes a `features` field per chain (for example, `swap`, `predict`, `perps`). Use `mm chains list --json` to inspect feature availability programmatically.

For chains not covered by the Accounts API, `mm wallet balance` falls back to direct RPC queries via Multicall3.

## 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.
