the game is already build, when i do npm start, it renders the game on my browser prompting a login on metamask, after logging in, the players have the option of either using blockchain in which case, they can play it remotely. when the blockchain option is enabled, a metamask interface comes on prompting the players to bet with 0.003 ETH, but i dont want to use ETH for the betting, instead they bet with 100 tenup token, am currently finding it difficult to change from 0.003 ETH to 100 TUP. The second challenge is that, the contract is currently deployed on Rinkeby Test Network, but then i want to move it to ethereum mainnet without altering any of the functionality of the game. these are the two areas am completely lost at. the betting is such that the winner of the game goes with all the tokens (200 for two players, 400 for four players)
