4. Adding USDC to Metamask (optional)
MATIC is Polygon’s native cryptocurrency token. MATIC is useful to make transactions and purchase on this network, but its exchange value changes over time.
To buy our NFTs, you are going to use USDC instead, a stable crypto-currency that maintain a value of 1$.
This step is not essential, because USDC you’re going to buy in the next steps will be visible in “My Wallet” section on OpenSea, once you made access through MetaMask.

- On the page you see, in the field “Token Contract Address”, copy and paste this string:
0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174
- If you entered the string correctly, the fields “Token Symbol” and “Decimals of Precision” will fill out automatically.
