Metamask equivalent in Web3.js: Hash Signature messages
When using Ethereum portfolios such as metamms, Signature Messages is a key step for Blockchain transactions and interactions. In this article, we will study how to repeat the equivalent functionality of Metamaska on Web3.js.
What is Metamascus Ethereum eth.sign?
The metamic method Ethereum.esh.sign generates a message signature using a public key format Ethereum (EIP-7). This method is commonly used to sign chain messages as interaction with smart contracts or sending transactions to external banknotes.
Metamask Replication in Web3js: Hash Signature messages
To replicate this functionality of Web3js, you can use the Ethereum-Signmessage feature from the Web3js library. This feature accepts a message and public key as a recording and returns signature.
Here is an example of a code clip showing how to sign a hash message using a metamam equivalent method:
`Javascript
CONST Web3 = Required (‘Web3’);
// Set a copy to a portfolio from Metamask
CONST metamascus = new web3.web3 (new window.ethereum);
// Determine a signature message
CONSTAGE = ‘Greetings, the world!’;
// generate the public key from your wallet
Metamascus.getAccount (). ((Account) => {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{о о о о о оо оо оо о о о о о о о о о о о о о о о о о о о feed {{{
CONST Publicy = Account.Publiscy;
Console.log (Public Key: $ {Publicy});
// Sign a hash message using EIP-7 format
Const signature = metamask.Thereumsignmessage (message, publiciscey);
Console.log (signature: $ {signature});
});
`
Run Web3.js
You can use the Ethereum-Potpisansage feature to sign messages in Web3. Here is an example of performance:
`Javascript
CONST Web3 = Required (‘Web3’);
// Set the Metamask portfolio specimens (replace with your own location)
CONST metamascus = new web3.web3 (new window.ethereum);
// Define a call back feature for the sign of the sign of the sign
Functional Sign (Message, Publicky) {)
Return of metamask.Thereumsignmessage (message, publiciscey);
It
// Example use:
Metamascus.getAccount (). ((Account) => {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{о о о о о оо оо оо о о о о о о о о о о о о о о о о о о о feed {{{
CONST Publicy = Account.Publiscy;
Console.log (Public Key: $ {Publicy});
// Sign a hash message
Const Signature = Signals (‘Greetings, World!’, Publicy);
Console.log (signature: $ {signature});
});
`
Tips and Variations
- Be sure to replace
Window.ThereumYour own copy of Ethereum portfolio service provider.
- You can adjust the ‘Signmessage’ feature to maintain different types of messages (eg, incomprehensible with signature).
- To check the signature, you will need the private key to signature signature and then use the same private signature key using
Etters-Potivinemessage.
- For more information about web3.js and its various signature methods, see the official documentation: <
Following this guide, you should be able to repeat the equivalent functionality of the Ethereum Eth.Sign Metamascus method in web3.js. Good luck coding!
