RewardsController
The RewardsController is designed to store and distribute rewards to accounts that interact with the Markets' different variable and fixed pools.
It calculates the total amount of rewards to distribute and determines the allocation between the pools based on a dynamic distribution model. Accounts can claim their rewards through the contract, and their claimable rewards can be queried at any time using the
claimable
