User will login with metamask and as the first token will be a very simple version with no taxes etc, the user will enter supply, name, symbol and decimals and will charge a small fee that will go to admin wallet and will deploy to the blockchain and send all tokens to owner/deployer. Need this to pass audits, owner cannot mint, cant make fees, all totally secure. Owner can renounce. The app/dapp will allow my address as admin to mint tokens without fee. The app/dapp will be able to create and deploy tokens on BSC and ETH. *This is version 1. We will include many other kinds of tokens onto the app after initial release.
