Canister Balances

Theory

In a manner similar to centralized exchanges, which take in deposited assets and keep track of user balances within their database, the Finny Protocol also accepts asset deposits and manages individual user balances within its canister using a structure known as the book balance. Please see #Depositing Assets and #Withdrawing Assets for instruction on sending and removing assets from the canister.
