# How to connect to the Tempo network

You can connect with Tempo like you would with any other EVM chain.

Tempo Mainnet has been live since March 18, 2026. Use mainnet, chain ID `4217`, for Tempo Wallet, production assets such as pathUSD, and live payment flows. Moderato, chain ID `42431`, is the separate public testnet for development.

## Connect using a Browser Wallet

Click on your browser wallet below to automatically connect it to the Tempo network.

Connect a wallet in the interactive web page.

:::warning
Note that on some wallets, you might see an unusually high "balance". This is because, historically, blockchain wallets have always assumed that a blockchain has a "native gas token". On Tempo, there is no native gas token, and so the value shown is a placeholder. See [EVM Differences](https://tempo.xyz/developers/docs/quickstart/evm-compatibility#handling-eth-native-token-balance-checks) for more information on this quirk.

## Connect via CLI

To connect via CLI, we recommend using [`cast`](https://getfoundry.sh/cast/overview/), which is a command-line tool for interacting with Ethereum networks. To install cast, you can read more in the [Foundry SDK docs](https://tempo.xyz/developers/docs/sdk/foundry#get-started-with-foundry).

```bash /dev/null/monitor.sh#L1-11
# Check block height (should be steadily increasing)
cast block-number --rpc-url https://rpc.tempo.xyz
```
