TransferStrategyInstalled

Parameters

Name
Type
Description

reward

address

transferStrategy

address

The address of TransferStrategy contract

RewardOracleUpdated

Emitted when the reward oracle is updated

Parameters

Name

setClaimer

Whitelists an address to claim the rewards on behalf of another address

Parameters

Name
Type
Description

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

Name
Type
Description

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.
