Functions
This function transforms 0x prefixed hex string into an elixir binary
Returns the address that created the signature for a personal signed message on the ETH network. Useful for checking metamask signatures. Raises an error if sig is invalid.
Returns the address that created the signature for a typed structured data signed message on the ETH network. Useful for checking metamask signatures. Raises an error if sig is invalid.
