This repository contains the payload to update the AAVE V2 WETH Liquity Pool interest rate strategy.
The Proposal Payload does the following:
- Sets the new interest rate strategy address.
The new interest rate strategy is deployed here: https://etherscan.io/address/0x853844459106feefd8C7C4cC34066bFBC0531722
The changes are as follows:
==========================================

------------------------------------------
| Base | 0 | 0 |
------------------------------------------
| VARIABLE RATES |

The function used to set the strategy comes from the @aave-address-book library
/**
* @dev Sets the interest rate strategy of a reserve
* @param asset The address of the underlying asset of the reserve
* @param rateStrategyAddress The new address of the interest strategy contract
**/
function setReserveInterestRateStrategyAddress(
address asset,
address rateStrategyAddress
) external;
- Sets the new reserve factor for the liquidity pool:
The function used to set the reserve factor comes from the @aave-address-book library
/**
* @dev Updates the reserve factor of a reserve
* @param asset The address of the underlying asset of the reserve
* @param reserveFactor The new reserve factor of the reserve
**/
function setReserveFactor(address asset, uint256 reserveFactor) external;
It requires Foundry installed to run. You can find instructions here Foundry installation.
To set up the project manually, run the following commands:
$ git clone https://github.com/llama-community/aave-interest-rate-update.git
$ cd aave-interest-rate-update/
$ npm install
$ forge installDuplicate .env.example and rename to .env:
- Add a valid mainnet URL for an Ethereum JSON-RPC client for the
RPC_MAINNET_URLvariable. - Add a valid Private Key for the
PRIVATE_KEYvariable. - Add a valid Etherscan API Key for the
ETHERSCAN_API_KEYvariable.
make build- build the projectmake test [optional](V={1,2,3,4,5})- run tests (with different debug levels if provided)make match MATCH=<TEST_FUNCTION_NAME> [optional](V=<{1,2,3,4,5}>)- run matched tests (with different debug levels if provided)
make deploy-payload- deploy and verify the payloadmake deploy-proposal- deploy proposal on mainnet
To confirm the deploy was successful, re-run your test suite but use the newly created contract address.
