StdConstants

State Variables

VM

Cheat code address. Calculated as address(uint160(uint256(keccak256("hevm cheat code")))).

Vm internal constant VM = Vm(0x7109709ECfa91a80626fF3989D68f67F5b1DD12D);

CONSOLE

console.sol and console2.sol work by executing a staticcall to this address. Calculated as address(uint160(uint88(bytes11("console.log")))).

address internal constant CONSOLE = 0x000000000000000000636F6e736F6c652e6c6f67;

CREATE2_FACTORY

Used when deploying with create2. Taken from https://github.com/Arachnid/deterministic-deployment-proxy.

address internal constant CREATE2_FACTORY = 0x4e59b44847b379578588920cA78FbF26c0B4956C;

DEFAULT_SENDER

The default address for tx.origin and msg.sender. Calculated as address(uint160(uint256(keccak256("foundry default caller")))).

address internal constant DEFAULT_SENDER = 0x1804c8AB1F12E6bbf3894d4083f33e07309d1f38;

DEFAULT_TEST_CONTRACT

The address of the first contract CREATEd by a running test contract. When running tests, each test contract is CREATEd by DEFAULT_SENDER with nonce 1. Calculated as VM.computeCreateAddress(VM.computeCreateAddress(DEFAULT_SENDER, 1), 1).

address internal constant DEFAULT_TEST_CONTRACT = 0x5615dEB798BB3E4dFa0139dFa1b3D433Cc23b72f;

MULTICALL3_ADDRESS

Deterministic deployment address of the Multicall3 contract. Taken from https://www.multicall3.com.

IMulticall3 internal constant MULTICALL3_ADDRESS = IMulticall3(0xcA11bde05977b3631167028862bE2a173976CA11);

SECP256K1_ORDER

The order of the secp256k1 curve.

uint256 internal constant SECP256K1_ORDER =
