# Setting up MetaMask

{% hint style="success" %}
This exercise requires you to add the Avalanche Fuji Testnet and get testnet LINK and AVAX tokens into Metamask
{% endhint %}

The [Getting Started | Chainlink Documentation](https://docs.chain.link/chainlink-functions/getting-started/#deploy-a-functions-consumer-contract-on-sepolia) uses Ethereum Sepolia, but you will use Avalanche Fuji for your project.

### **Configure Avalanche Fuji Testnet in MetaMask**

Go to [Avalanche Fuji Testnet RPC and Chain settings | ChainList](https://chainlist.org/chain/43113) and connect your wallet by clicking the “Connect Wallet” button:

Once you are connected to chainlist.org, click the “Add to Metamask” button at the bottom:

Click the “Approve” button at the bottom right:

MetaMask will proceed to ask you to switch the network, so click the "Switch network" button at the bottom right:

Now MetaMask will be on the Avalanche Fuji Testnet:

### Faucets

Please refer to the previous section on acquiring testnet tokens:

[Setting up MetaMask](/bootcamp-2024/4.-cross-chain-tokens-with-chainlink-ccip/setting-up-metamask.md#getting-testnet-tokens-from-faucets)

Once you have these tokens in MetaMask and are on the Avalanche Fuji Testnet, you may now proceed with the Chainlink Functions exercises!
