revert v3utils

This repository contains the smart contracts for revert v3utils.

It uses Foundry as development toolchain.

Setup

Install foundry

https://book.getfoundry.sh/getting-started/installation

Install dependencies

forge install

Tests

Most tests use a forked state of Ethereum Mainnet. You can run all tests with:

forge test --via-ir

Because the v3-periphery library (Solidity v0.8 branch) in PoolAddress.sol has a different POOL_INIT_CODE_HASH than the one deployed on Mainnet this needs to be changed for the integration tests to work properly.

bytes32 internal constant POOL_INIT_CODE_HASH = 0xa598dd2fba360510c5a8f02f44423a4468e902df5857dbce3ca162a43a3a31ff;

needs to be changed to

bytes32 internal constant POOL_INIT_CODE_HASH = 0xe34f199b19b2b4f47f68442619d555527d244f78a3297ea89325f843f87b8b54;

Deployment for Pancakeswap

There need to be done some minimal changes to the code and linked library interfaces.

Change POOL_INIT_CODE_HASH in PoolAddress.sol to

bytes32 internal constant POOL_INIT_CODE_HASH = 0x6ce8eb472fa82df5469c6ab6d485f17c3ad13c8cd7af59b3d4a8026c5ce0f7e2;

IUniswapV3PoolState change slot0() function to this (note the uint32 for feeProtocol)

function slot0()
        external
        view
        returns (
            uint160 sqrtPriceX96,
            int24 tick,
            uint16 observationIndex,
            uint16 observationCardinality,
            uint16 observationCardinalityNext,
            uint32 feeProtocol,
            bool unlocked
        );

Add this function to IPeripheryImmutableState

function deployer() external view returns (address);

Automator.sol

Add to storage variables:

address private immutable deployer;

Add to constructor:

deployer = npm.deployer();

Change method:

// get pool for token
function _getPool(
    address tokenA,
    address tokenB,
    uint24 fee
) internal view returns (IUniswapV3Pool) {
    return
        IUniswapV3Pool(
            PoolAddress.computeAddress(
                deployer,
                PoolAddress.getPoolKey(tokenA, tokenB, fee)
            )
        );
}
