How do I see what’s in a smart contract?

So I'm learning solidity and stopped for a bit to ponder. If I wanted to see the smart contract for a balance pool on etherscan, is there a way to do it? How would I deploy a coin that would essentially be a balance pool of two token pairs? Would it be a legitimate coin based off of that? Maybe it can run strategic buying and staking modes to increase its value? To make it self sustaining? And eventually reach DAO status by buying up enough Ethereum for a node? Then make a front end for some special reason?
