FluidVaultRewards

This contract is designed to adjust the supply rate magnifier for a vault based on the current collateral supply & supply rate. The adjustment aims to dynamically scale the rewards given to lenders as the TVL in the vault changes.

The magnifier is adjusted based on a regular most used reward type where rewardRate = totalRewardsAnnually / totalSupply. Reward rate is applied by adjusting the supply magnifier on vault. Adjustments are made via the rebalance function, which is restricted to be called by designated rebalancers only.

validAddress

modifier validAddress(address value_)

Validates that an address is not the zero address

onlyRebalancer

modifier onlyRebalancer()

Validates that an address is a rebalancer (taken from reserve contract)
