What's next for Crypto Recycling Machine

Implement a back office web3 app, which will be used to manage the recycling machine contracts. It will allow administrator to deploy a new Recycling Machine contracts, manage existing ones and follow theirs statistics. For example, admin could see the balance, total amount donated, number of payouts, etc.
