Metamask: Sign a transaction with Metamask which will be submitted later using a custom backend
Presenting Metamask: Perfect transaction experience
As the creation and implementation of decentralized applications (DAPP) on blockchain platforms, it is necessary to have efficient and friendly transaction management tools. In this article, we will examine how you can integrate the popular Metamask portfolio in a personalized micro service, providing a soft transaction.
What is a metamask?
Metamask is an interface based on a network that allows users to store, send and receive ether (ETH) and other cryptocurrencies at the Ethereum blockchain. It is widely used to create DAPP and ensure a safe way of interaction with the Ethereum network. Thanks to Metamask, you can easily sign transactions using your favorite wallet.
Why use a metamask?
Metamask offers several benefits when it comes to transaction management:
* Ease of use : Subscribe to transactions without worrying about complex gas prices or network drafts.
* Security : Store and manage private keys on the user’s device safely.
* Faster transactions : immediately start transactions thanks to the optimized Metamask network.
Metamas integration with a personalized micro -sewl
To sign a transaction with a metamask in a personalized micro-service, follow the following steps:
Step 1: Install Metamask
First you need to install the Metamask portfolio on the user’s device. You can download it from the official Metamask website.
Step 2: Integrate Metamaszek in micro-services
To integrate a metamask with a non-standard micro-service, you need to create a personalized facilities using a selected programming language (e.g. Node.js, Python). Here are some examples:
with node.js
`Javascript
Const Express = requires ("Express");
Const app = express ();
Consta Metamask = requires ("Metamask-Web3");
// Configure the Metamask connection
Consta Metamaskclient = New Metamask ({{
Says: "your_masternode",
Privatey: "your_private_key",
Url: "your_metamask_url"
});
// Define the function for signing transactions
App .st ('/sign-transaction', (req, res) => {
Const
Metamaskclient.signtransaction (transatonhash) .Then ((result) => {
// process the signed transaction
console.log (result);
Res.status (200). Send ({Success: True});
}). Catch ((error) => {
console.error (error);
res.status (500).
});
});
with Python
`Python
Import web3
Configure the Metamask connection
W3 = web3.web3 ()
meta_mask_client = w3.et.account.connect ('your_masternode_url')
Define transaction signing function
Def SIGN_TRANSACTION (transaction_hash):
Try:
Result = meta_mask_client.signtransaction (transaction_hash)
Process the signed transaction
Return result.hex ()
Except for the exception such as E:
Printing (E)
Do not return any
Example of use:
transaction_hash = "your_transaction_hash"
signed_result = sign_transaction (transaction_hash)
If Sonned_result is missing:
Print (signed_result)
By following these steps, you can integrate a metamask with a non-standard micro-service and provide users with an excellent transaction. Remember to replace the spaces reserved for the actual details of the metamask connection and the Ethereum network settings.
Application
Metamask provides a convenient way of signing transactions with your favorite portfolio, eliminating the need for manual configuration or complex gas price calculations. By integrating a metamask with a personalized micro service, you can improve the user’s experience and increase DAPP work flow efficiency.
