Aave incentives

Introduction

This repo contains the code and implementation of the contracts used to activate the liquidity mining program on the main market of the Aave protocol.

Implementation

The rewards are distributed in the form of stkAAVE, which is obtained by staking Aave in the Safety Module Staking contract located at https://etherscan.io/address/0x4da27a545c0c5b758a6ba100e3a049001de870f5.

The incentives controller contract, StakedTokenIncentivesController, stakes the rewards while transferring the obtained stkAAVE to the claiming user.

The implementation logic is defined as follow:

  • Each asset has a defined emissionPerSecond
  • For each asset, an assetIndex keeps track of the total accumulated rewards
  • For each user, a userIndex keeps track of the user accumulated rewards
  • On handleAction(), that is triggered whenever an aToken/debt Token is minted/burned by a user, the userIndex and the assetIndex are accumulated depending on the time passed since the last action
  • At any point in time the user pending rewards can be queried through the getRewardsBalance() function
