personal_sign

Presents a plain text signature challenge to the user and returns the signed response. Prepends a safe prefix to the signed message to prevent the challenge tricking users into signing a financial transaction. MetaMask implements personal_sign similarly to the Go Ethereum client's eth_sign implementation. MetaMask's personal_sign doesn't accept a password. This method requires that the user has granted permission to interact with their account first, so make sure to call eth_requestAccounts (recommended) or wallet_requestPermissions first.

Parameters

Challenge(string)required

A hex-encoded UTF-8 string to present to the user. See how to encode a string like this in the browser-string-hexer module.

Address(string)required

The address of the requested signing account.

Returns

A hex-encoded signature.
