Metamask: Signing once-and-for-all recurrent transactions with a wallet such as MetaMask from a backend
sign repeated events with metamask: Guide
In recent years, Blockchain technology has become increasingly popular for different applications, including decentralized funding (defi), games and identity verification. One of the most important portfolio solutions is metamask, which allows users to manage their digital property on several Blockchain platforms. However, a significant restriction on the use of metamas or similar wallets is their inability to control repeated events directly from the background.
The problem of repeated events
Repeated events are essential for applications that force users to make repeated payments over time, such as ordering services, payment processing and online markets. The problem with Blockchain -based systems, such as metamask or other wallets, is that they can be heavy to accomplish in the background. Hence:
- Complexity : Completion of repeated events requires personal writing to control transaction logic, integration of payment gateway and portfolio management.
- Safety
: Managing repeated events in the background increases the insight surface to achieve potential safety vulnerabilities.
Solution: Using wallets with background services
To solve these restrictions, we can use portfolios, such as metamask or formatic, directly controlled by repeated events. Here is an overview of how it works:
- Portfolio Integration : Integrated with your selected portfolio (eg Metamaski) with your Bace service in a library or frame that supports the portfolio interaction.
2
- User Interface : Design an intuitive interface so that users can start recurring events, including repetitive payments and control options.
Code Example: Use of Metamask with Node.js
Here’s a simplified example of how you can use metamas in Node.JS to control repeated events:
`Javascript
Const Express = Require ('Express');
Const Expresswallet = Require ('Express-Wallet') (Express);
// To initialize the portfolio of the portfolio
Const wallet = new wallet ();
// Set up for repetitive payments
Asynchronous processererecuringpayment function () {
// Return user payment information in the database
Const User = Wait RecoveringPaymentinfo ();
// Treat your payment with metamask
to try {
// Specify the recurring payment plan by means of metamask
Wallet.Setplan (User.id, "repeated fee");
// Create an event to launch a repetitive payment
Const Txid = Wait wallet.sendtransaction (User.id, "Start one -time payments");
// returns the transaction ID for future reference
Return TXID;
} Catch (error) {
Console.error (error);
}
}
// Set the motorway to manage recurrent payments
App.post ('/ repeated charges', processrecurringpayment);
Port Const = 3000;
app.lisen (gate, () => {
Console.log (server listens to the gate $ {port});
});
` ‘
conclusion
Implementing repeated events from the background program by using portfolios, such as metamask, can simplify the development process and reduce safety risks. By integrating the portfolio selected to Backen, you can create a solid system to manage repetitive fees and provide an exceptional user experience.
advice
- Select a suitable library or portfolio frame that supports the interaction of the portfolio.
- Design a safe and reliable system to manage recurrent events.
- Integrates the portfolio in the background service with a library or frame.
- Create a friendly user interface for users to start recurrent payments.
