Process
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.
donateRewards()
function donateRewards () external
Donates purchased rewards, eg MTA, to staking contracts via the Emissions Controller.
addStakingContract()
function addStakingContract (uint16 _stakingDialId) external
Adds a new staking contract that will receive MTA rewards
Parameter
Type
Description
_stakingDialId
uint16
dial identifier from the Emissions Controller of the staking contract.
