This is showcase project and an experimental lab based on the features offered by the Web3
This web application uses fake money with no value — have i heard fiat ? ( ¬ ‿¬)
A web3 wallet is a web browser extension that facilitates access to Ethereum and Ethereum-compatible blockchains (like Polygon).
To interact with this web application you will need a wallet on your browser.
This is needed to sign transactions, purchase NFTs or interact with smart contract.
If you really don't know what it is you can check on google and YT there is plenty of great beginner content available.
As an alternative you can use Brave
This webApp is based on Polygon. This is what we call a Layer 2 and for our purpuse it have a some advantage like faster transaction and cheaper gas fee. Also to avoid paying real money we are base on the Polygon Testnet called Mumbai.
You need to configure your wallet to use the Mumbai network. You can find how to this on internet, but the easiest way if you use metamask is probably yo use Chainlist.org and search for Polygon Testnet Mumbai.
