Metamask Equivalent in Web3.js: Signature hash messages
When using Ethereum wallets, such as metamas, signature messages are a key step in blockchain transactions and interactions. In this article, we examine how to repeat the equivalent functionality of metamaska to web3.js.
What is Metamascus Ethhereum Eth.sign?
The “Ethereum.esth.sign” metamas method generates a signature for a message using the Ethereum Public Key (EIP-7) format. This method is usually used to sign messages on a chain, such as interaction with intelligent contracts or send transactions to external banknotes.
Metamask Replication on Web3js: Signature hash messages
To repeat this feature, you can use the Ethereum-Signmessage feature from the Web3JS directory on Web3js. This feature takes a message and a public key as an entry and returns a signature.
Here is an example of a code clip that shows how to sign a hash message using a metamic equivalent method:
`Javascript
Const Web3 = Required ('Web3');
// Set the instance of Metamask's wallet
Const metamascus = new web3web3 (new window.ethereum);
// Enter a signature message
Const message = 'Greetings, the world!';
// generate the public key from your wallet
Metamascus.getaccount (). then ((account) => {{{
CONST publickey = Account.Publiscy;
Console.log (Public key: $ {publickey});
// sign the hash message using EIP-7 format
Const signature = metamask.ethereumsignmessage (message, publiscey);
Console.log (signature: $ {signature});
});
Web3.js implementation
You can use the Ethereum-PotpisanSage feature for Web3 signature messages. Here is an example of implementation:
`Javascript
Const Web3 = Required ('Web3');
// Set the instance of metamask's wallet (replace your own placement)
Const metamascus = new web3.web3 (new window.ethereum);
// Determine the return call function to the signal message signal
Function Signmessage (Message, Publicky) {)
Return metamask.ethereumsignmessage (message, publiscey);
Iche
// Use Example:
Metamascus.getaccount (). THEN ((account) => {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{
CONST publickey = Account.Publiscy;
Console.log (Public key: $ {publickey});
// log in a hash message
Const Signature = Signalsage ('Greetings, World!', Publickey);
Console.log (signature: $ {signature});
});
Tips and variations
- Be sure to replace your own copy of “window.ethereum” for Ethereum Wallet service provider.
- You can set the “SignMessage” function to support various types of messages (eg Signature).
- To check the signature, you will need the Signature Signature Signature Private Key and then use the same private key to produce signatures using “Etters-Potivinessage”.

Following this guide, you should be able to repeat the equivalent functionality of the Ethhereum Eth.sign metamascus method of web3.js. Good luck with coding!
