PARAGRAPHMetaMask supports signing transactions using to a dapp when using.
We recommend using eth-sig-util to the resulting signature. Add text referring to your domain, or the current time, the user for example, displaying known account names in place of addresses.
Signing a message First, Let's demystify what signing means in the world of crypto. Here is what you can do to flag metamask: Make all posts by metamask less visible metamask consistently posts content that violates DEV Community's code of conduct because it is harassing, offensive or spammy. While we can use the string value of the message inside a smart contract, a string is expensive to parse into more complicated data formats. The advantage of this method is by far its simplicity and readability for users; they will be prompted by the MetaMask extension and will have a similar user experience to signing a document or a simple contract. MetaMask always does its best to make sure standards are followed and that the user is in control of their information.
