Currently only support is for metamask. More wallet connections are a must.

I've started working on this here https://github.com/burakkaraceylan/nft-marketplace/tree/moar_wallets

I added WalletConnect and intend to add more. I assumed Infura RPC nodes would be used so you have to set REACT_APP_INFURA_KEY environment variable. I also added .env to gitignore.

It would be nice if you design a pop-up page that will open when the user clicks "connect" where he can choose which wallet to connect.
