IRewardsController
Defines the basic interface for a Rewards Controller.
ClaimerSet
Emitted when a new address is whitelisted as claimer of rewards on behalf of a user
Parameters
user
address
The address of the user
claimer
address
The address of the claimer
RewardsClaimed
Emitted when rewards are claimed
Parameters
user
address

reward
address
The address of the token reward is claimed
to
address
The address of the receiver of the rewards
claimer
address
The address of the claimer
amount
uint256
The amount of rewards claimed
TransferStrategyInstalled
Emitted when a transfer strategy is installed for the reward distribution
Parameters
reward
address
The address of the token reward
transferStrategy
address
The address of TransferStrategy contract
RewardOracleUpdated
Emitted when the reward oracle is updated
Parameters
reward
address
The address of the token reward
rewardOracle
address
The address of oracle
setClaimer
Whitelists an address to claim the rewards on behalf of another address
Parameters
user
address
The address of the user
claimer
address
The address of the claimer
setTransferStrategy
Sets a TransferStrategy logic contract that determines the logic of the rewards transfer
Parameters
reward
address
The address of the reward token
transferStrategy
contract ITransferStrategyBase
The address of the TransferStrategy logic contract
setRewardOracle
At the moment of reward configuration, the Incentives Controller performs a check to see if the reward asset oracle is compatible with IEACAggregator proxy. This check is enforced for integrators to be able to show incentives at the current Aave UI without the need to setup an external price registry
Sets an Aave Oracle contract to enforce rewards with a source of value.
Parameters
reward
address
The address of the reward to set the price aggregator
rewardOracle
contract IEACAggregatorProxy
The address of price aggregator that follows IEACAggregatorProxy interface
getRewardOracle
Get the price aggregator oracle address
Parameters
reward
address
The address of the reward
Return Values
[0]
address
The price oracle of the reward
getClaimer
Returns the whitelisted claimer for a certain address (0x0 if not set)
Parameters
user
address
The address of the user
Return Values
[0]
address
The claimer address
getTransferStrategy
Returns the Transfer Strategy implementation contract address being used for a reward address
Parameters
reward
address
The address of the reward
Return Values
[0]
address
The address of the TransferStrategy contract
configureAssets
Configure assets to incentivize with an emission of rewards per second until the end of distribution.
Parameters
config
struct RewardsDataTypes.RewardsConfigInput[]
The assets configuration input, the list of structs contains the following fields: uint104 emissionPerSecond: The emission per second following rewards unit decimals. uint256 totalSupply: The total supply of the asset to incentivize uint40 distributionEnd: The end of the distribution of the incentives for an asset address asset: The asset address to incentivize address reward: The reward token address ITransferStrategy transferStrategy: The TransferStrategy address with the install hook and claim logic. IEACAggregatorProxy rewardOracle: The Price Oracle of a reward to visualize the incentives at the UI Frontend. Must follow Chainlink Aggregator IEACAggregatorProxy interface to be compatible.
handleAction
Called by the corresponding asset on transfer hook in order to update the rewards distribution.
The units of totalSupply and userBalance should be the same.

userBalance
uint256
The previous user balance prior to balance change
