FluidVaultBorrowRewards

This contract is designed to adjust the borrow rate magnifier for a vault based on the current debt borrow & borrow 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 / totalborrow. Reward rate is applied by adjusting the borrow 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)

constructor

constructor(contract IFluidReserveContract reserveContract_, contract IFluidVaultT1 vault_, contract IFluidLiquidity liquidity_, uint256 rewardsAmt_, uint256 duration_, address initiator_, address debtToken_, address governance_) public

Calculates the new borrow rate magnifier based on the current debt borrow (vaultTVL()).

Return Values

Name	Type	Description
magnifier_	uint256	The calculated magnifier value.
ended_	bool

currentBorrowMagnifier

function currentBorrowMagnifier() public view returns (uint256)

returns the currently configured borrow magnifier at the VAULT.

vaultBorrowTVL

function vaultBorrowTVL() public view returns (uint256 tvl_)

returns the current total value locked as debt (TVL) in the VAULT.

getBorrowRate

function getBorrowRate() public view returns (uint256)

Parameters

Name	Type	Description
startTime_	uint256	The timestamp at which to start the rewards.

queueNextRewards

function queueNextRewards(uint256 rewardsAmount_, uint256 duration_) external
