Setting up MetaMask

Getting testnet networks and tokens configured on MetaMask

For this section, we will add Avalanche Fuji Testnets and add AVAX, LINK and USDC testnet tokens. We recommend you do this Section after complete Section 2 and Section 3 so that most of the set up is already done. Let's go!

Add the Sepolia LINK Token Address to MetaMask

Navigate to LINK Token Contracts | Chainlink Documentation and click the “Add to wallet” button:

Add the LINK token directly into MetaMask

If you are not already on Ethereum Sepolia, the button will ask to "Switch network and add to wallet"

MetaMask will pop-up and click "Add token" button:
