rememberKey
Signature
function rememberKey(uint256 privateKey) external returns (address);
Description
Stores a private key in forge’s local wallet and returns the corresponding address which can later be used for broadcasting.
Examples
Derive the private key from the test mnemonic at path m/44'/60'/0'/0/0, remember it in forge’s wallet and use it to start broadcasting transactions:
string memory mnemonic = "test test test test test test test test test test test junk";
uint256 privateKey = vm.deriveKey(mnemonic, 0);
address deployer = vm.rememberKey(privateKey);
vm.startBroadcast(deployer);
...
vm.stopBroadcast();
Load a private key from the PRIVATE_KEY environment variable and use it to start broadcasting transactions:
address deployer = vm.rememberKey(vm.envUint("PRIVATE_KEY"));
vm.startBroadcast(deployer);
...
vm.stopBroadcast();
