personal_sign

Presents a plain text signature challenge to the user and returns the signed response. Equivalent to eth_sign on some other wallets, and prepends a safe prefix to the signed message to prevent the challenge tricking users into signing a financial transaction. This method requires that the user has granted permission to interact with their account first, so make sure to call eth_requestAccounts first.
