Build a Crypto platform

I want to build a crypto platform like [login to view URL] The code for this is already built and available on github. I want to build the same app on ETH, Binance smart chain, DOT platform and ADA platform. Its a privacy address generator. The concept is anyone deposit a coin into this project address and we scramble that coin into different address. The client will be able to receive this coin using a secret key which we generate and give to clients. Using that secret key, client will be able to withdraw the coint they deposit in to our wallet. If you have any idea about all these platforms, let me know. I also want staking and yield farming for all the blockchain.
