This repository contains an implementation of incentives controller for AStETH token in AAVE protocol. AAVE protocol allows the use of incentives controllers in their AToken, VariableDebtToken, and StableDebtToken contracts to distribute rewards on a token mint, burn or transfer. Lido's integration in AAVE uses a custom implementation of AToken - AStETH.

Contains logic to the linear distribution of reward tokens across holders of AStETH, proportional to the number of tokens the user hold. Contract inherits from the OpenZeppelin's Ownable contract and implements Unstructured Storage pattern to simplify future updates of incentivization logic. The contract uses RewardsUtils library to reusable and convenient work with rewards

Provides structs and a library for convenient work with staking rewards distributed in a time-based manner.

To use the tools provided by this project, please pull the repository from GitHub and install its dependencies as follows. It is recommended to use a Python virtual environment.

git clone https://github.com/lidofinance/aave-asteth-incentives-controller.git
cd aave-asteth-incentives-controller
npm install
poetry install
poetry shell

Compile the smart contracts:

brownie compile # add `--size` to see contract compiled sizes

The fastest way to run the tests is:

brownie test

Run tests with coverage and gas profiling:

brownie test --coverage --gas

Contains script to deploy and setup RewardsManager and AaveAStETHIncentivesController contracts. Deployed RewardsManager used as rewards distributor in the AaveAStETHIncentivesController contract.

Contains script to finalize deployment of AaveAStETHIncentivesController. This script must be run after deployment of AStETH token, to set address of stakingToken. As part of the initialization transfers ownership to Lido's Agent.
