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 (recommended) first.

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.

string

Match pattern:^0x[a-fA-F\d]+$

2. address (required)

The address of the requested signing account.

string

Match pattern:^0x[0-9a-fA-F]{40}$
