deriveKey

Signature

function deriveKey(
  string calldata mnemonic,
  uint32 index
) external returns (uint256);

function deriveKey(
  string calldata mnemonic,
  string calldata path,
  uint32 index
) external returns (uint256);

Description

Derive a private key from a given mnemonic or mnemonic file path.

The first signature derives at the derivation path m/44'/60'/0'/0/{index}. The second signature allows you to specify the derivation path as the second parameter.

Examples

Derive the private key from the test mnemonic at path m/44'/60'/0'/0/0:

string memory mnemonic = "test test test test test test test test test test test junk";
uint256 privateKey = vm.deriveKey(mnemonic, 0);

Derive the private key from the test mnemonic at path m/44'/60'/0'/1/0:

string memory mnemonic = "test test test test test test test test test test test junk";
uint256 privateKey = vm.deriveKey(mnemonic, "m/44'/60'/0'/1/", 0);
