A Metamask wallet with some MATIC (the Polygon blockchain cryptocoin). So you need to set up a crypto wallet and change some fiat currency to crypto currency.
If you are lucky enough it will be free, just gas taxes in polygon: practically 0.
Something more after a while.
If you wanna see real time info about the smart contract status you need to use Metamask and be connected to the Polygon network.
If you want to mint a G2DA all you need is a metamask account with some MATIC (Polygon's cryptocurrency) for gas.
Click on the connect button to go to metamask if you already has it, or to install metamask if you are new to this world.
This G2DA is already minted. Watch this G2DA on OpenSea!
