MATIC is the native token of the Polygon network and is used to pay network and gas fees. You will need MATIC on DoinGud in order to cover network fees for transacting on the Polygon network, similar to ETH gas fees if you're transacting on the Ethereum network (or other blockchain networks). Don't worry though! Transacting on Polygon with MATIC is inexpensive and often costs less than $0.10 per transaction, and even just 1 $MATIC can cover over 100+ transactions.
*Important: You don't need to transfer/bridge both USDC & MATIC to your Polygon wallet from Ethereum Mainnet. You may just transfer USDC and swap some for MATIC using Polygon's Swap Tool (Option 2) .
