Generation of EIP-721 and EIP-1155 signatures without using Metamask
As a web3 developer, you are familiar with the importance of using Metamask to interact with decentralized applications (APPS). However, some users may encounter problems or limitations when trying to create multiple signatures EIP-721 and EIP-1155 by accepting the Popup Metamask one by one. In such cases, generating these signatures at the programming level without using Metamask can be a challenge.
What are the EIP-721 and EIP-1155 signatures?
Before immersing yourself in the solution, we quickly review what the EIP-721 and EIP-1155 signatures represent:
* EIP-721 : a standard token (NFT) not whistling for digital collectible objects. Each NFT is assigned a unique identifier (for example a Uri or hash).
* EIP-1155 : a standard for fungible tokens, which allows you to create more copies of the same token without changes.
Generation of signatures at the programming level
To generate these signatures at the programming level without using Metamask, you can use the following methods:
1
It is possible to use the `Eth_Sign provided by the Web3.js bookcase to sign the messages with your Ethereum account.
`Javascript
Const Web3 = Requirements (“Web3”);
// Set your Ethereum account provider
Const Provider = New Web3.Priders.httpprovider (‘
// Create a new web3 application
Const Web3 = New Web3 (Provider);
// define the message to be signed
Const Message = ‘Your message here …’;
Attempt {
// Sign the message with your Ethereum account address (in this case, the private key)
Const signature = wait web3.eth.sign (Message, Provider.Getaccount (‘Your_acount_Address’));
Console.log (`generated EIP-721/Mr.: $ {signature});
} Catch (error) {
console.error (error);
}
`

TheJsonwebtoken ‘library provides a more convenient way to generate signatures using Token Web Json.
`Javascript
Const JWT = requirement (‘Jsonwebtoken’);
// Define your Ethereum account provider
Const Provider = New Web3.Priders.httpprovider (‘
// Set your private key Ethereum account
Const Privatekey = ‘Your_private_key’;
Attempt {
// Sign the message with the Ethereum account address (in this case, the private key)
Const signature = jwt.sign ({Message: ‘Your message here …’}, Privatekey);
Console.log (`generated EIP-721/Mr.: $ {signature});
} Catch (error) {
console.error (error);
}

3. Use of a third -party bookcase or service
Several third-party bookstores and services are available that provide EIP-721 and EIP-1155 signature features without requesting Metamask:
* Ethers.js
: an open source library to interact with the Ethereum blockchain.
* Hardhat : a javascript framework for the construction of decentralized applications based on Ethereum (DAPPS).
After generating the signatures at the programming level, be sure to archive them safely and follow the best practices for the management of private keys and sensitive information.
While these methods can help you generate signatures EIP-721 and EIP-1155 without using Metamask, keep in mind that they can have limits or considerations on safety. Give the priority always to security when working with sensitive data and private keys.
