Deterministic State of the Blockchain Base

To perform the tests, the state of the blockchain needs to be deterministic. To achieve this:

• Set FORKING_URL variable in the .env file.
• In order to perform the tests correctly you may need to impersonate the address

Info about the state of the blockchain

• Blockchain: Base

• Block: 19197423

• Address with WEWE / WETH: 0x38019bc40f504be4546f24083ccaf0c8553c408a

• Block with the mint tx of the WEWE / WETH LP: 18720627

• Address with WETH / USDC: 0xAd3B97c3C22B00C900fB04d47B3037E33f1d07d9

• Block with the mint tx of the WETH / USDC LP: 19167068

Error codes

• INPM -> Invalid NonfungiblePositionManager address

Setting up white lists

White listed addresses can be set by creating the merkle root on the Merge contract. The merkle root can be created by running the following command:

yarn install
node scripts/merkle-root.js address.csv

The address.csv file should have the following format: Note, this file should be considered private and should not be shared.

address,amount
0x70997970C51812dc3A010C7d01b50e0d17dc79C8,100000000000000000000

The merkle root will be printed to the console, eg 0x403ff023bd4c929b68c940e8c21016d996bdd7b4ddd73cd42e82b2de3a8bcca3. This merkle root can be used to set the white list in the contract by the owner.

function setWhiteList(bytes32 merkleRoot) public onlyOwner {
    _merkleRoot = merkleRoot;
}

The front end will then need to:

1. Find the proof array for the address. This could be fetched from the server or be client side.
2. Call the contract with the proof array and the address

{
    Address: { '0x1234567890123456789012345678901234567891' },
    Proof: [
    '0xd575cdd1b7c6bdb5f45cf3f369c820b372528a8348abff17865199699970da6b',
    '0xef8897c94eaa91defb5bcf5eb1d3253c361a8315e842f60bb237531e4804e0f6'
    ]
}

function mergeWithProof(address account, uint256 amount, bytes32[] calldata proof) public {
    // ... check if the account is in the merkle tree
}

Turning off white list

The white list can be turned off by setting the merkle root to bytes(0). Then the contract will allow any address to merge, via merge(uint256 amount) or mergeAll().

    function merge(uint256 amount) external virtual whenNotPaused returns (uint256) {
        // ... check if the account is in the merkle tree
    }

    function mergeAll() external virtual whenNotPaused returns (uint256) {
        // ... check if the account is in the merkle tree
    }
