Functions

notifyRedistributionAmount()

function notifyRedistributionAmount (address _mAsset, uint256 _amount) external

Simply transfers the mAsset from the sender to here

Parameter	Type	Description
_mAsset	address	Address of mAsset
_amount	uint256	Units of mAsset collected

buyBackRewards()

function buyBackRewards (address[] mAssets, uint256[] minBassetsAmount, uint256[] minRewardsAmounts, bytes[] uniswapPaths) external

Buys reward tokens, eg MTA, using mAssets like mUSD or mBTC from protocol governance fees.

Parameter	Type	Description
mAssets	address[]	Addresses of mAssets that are to be sold for rewards. eg mUSD and mBTC.
minBassetsAmount	uint256[]	Minimum amount of bAsset tokens to receive for each redeem of mAssets. The amount uses the decimal places of the bAsset. Example 1: Redeeming 10,000 mUSD with a min 2% slippage to USDC which has 6 decimal places. minBassetsAmounts = 10,000 mAssets * slippage 0.98 * USDC decimals 1e6 = 1e4 * 0.98 * 1e6 = 1e10 * 0.98 = 98e8 Example 2: Redeeming 1 mBTC with a min 5% slippage to WBTC which has 8 decimal places. minBassetsAmounts = 1 mAsset * slippage 0.95 * WBTC decimals 1e8 = 0.95 * 1e8 = 95e6
minRewardsAmounts	uint256[]	Minimum amount of reward tokens received from the sale of bAssets. The amount uses the decimal places of the rewards token. Example 1: Swapping 10,000 USDC with a min 1% slippage to MTA which has 18 decimal places. minRewardsAmounts = 10,000 USDC * slippage 0.99 * MTA decimals 1e18 * MTA/USD rate 1.2 = 1e4 * 0.99 * 1e18 * 1.2 = 1e22 * 0.99 = 99e20 Example 1: Swapping 1 WBTC with a min 3% slippage to MTA which has 18 decimal places. minRewardsAmounts = 1 WBTC * slippage 0.97 * MTA decimals 1e18 * MTA/BTC rate 0.00001 = 1 * 0.97 * 1e18 * 0.00001 = 0.97 * 1e13 = 97e11
uniswapPaths	bytes[]	The Uniswap V3 bytes encoded paths.
