deriveRememberKey

Signature

function deriveRememberKey(string memory mnemonic, uint32 index) internal returns (address who, uint256 privateKey)

Description

Derive a private key from a mnemonic and also store it in forge's local wallet. Returns the address and private key.

Example

Get a private key and address from the test mnemonic at path m/44'/60'/0'/0/0. Use them to sign some data and start broadcasting transactions:

string memory mnemonic = "test test test test test test test test test test test junk";

(address deployer, uint256 privateKey) = deriveRememberKey(mnemonic, 0);

bytes32 hash = keccak256("Signed by deployer");
(uint8 v, bytes32 r, bytes32 s) = vm.sign(privateKey, hash);

vm.startBroadcast(deployer);
...
vm.stopBroadcast();

Get an address from the test mnemonic at path m/44'/60'/0'/0/0 to start broadcasting transcations:

string memory mnemonic = "test test test test test test test test test test test junk";

(address deployer, ) = deriveRememberKey(mnemonic, 0);

vm.startBroadcast(deployer);
...
vm.stopBroadcast();
