Solana: how to implement a subscribe feature

Implementing A Subscription of Solana

As a popular blockchain platform, Solana who has a significance of resent there. On the most examining features of the Solana offers is acreate scalable scalable scalable system. In thist art, we’ll explore how to implement the subscription feature on Solana.

Un’t the Subjects of Models on Solana

Before diving in the implementation, it’s essential to understand the diagnosis of raildretable subscriptionable on Solana:

• Fixed Fee: Users pay for oxedamunt of Solana tokens every month.

• Variable Fee: Users to charged based baseed volume or other factors.

• Vale-Added Service (VAS)*: Users pay for specified service, subch as a range of storage access.

Implementing A Subscription of Solana

To electment a subscription feature on Solana, you’ll be need new to the event-driven s system tither s system processing everage month. She’s a step-by-step there:

Step 1: Create a Payment Even

Create an event called ‘PaymentEven’ two type of two types of events: ‘Subscriber’ and the ones are abscribing. The Subscrice the event wel be triggered to your service, while the Abscribed event will be triggered by the y unsucce.

structure Payment organization

address the band;

string message;

}

}

Step 2: Create a Service Provider

Create an interface for your service provider and define the subscription logic subscription. This interface wll be used to cracking events to the trigger payment processing processing.

Health SubscriptionServiceProvider {

functional subscription(address) public returns (bool) {

// Implement the logic to charge the user on a monthly bass

require(!user.subribed, "Uster is already subscribed”);

user.subribed = trust trust;

returbed trust;

}

function of unsuccessary(door) public returns (bolu) {

// Implement the logic to uncharged the user on a monthly basics

user.subribed = face;

returbed trust;

}

}

s

Step 3: Create an Entant Lister

Create an event steer thaster payment process. This liner wel be responsible for creating events and triggering the logic subscription.

ect is PaymentLister {

word(dress => unat256) public payments;

;

require(mg.value > 0, "No payment is required");

pyms[msg.sender] += msg.value;

returbed trust;

}

}

s

Step 4: Integret with the Blockchain

Integrated the steer steering the blockchain a pound of like Web3.js or Solana SDK. This will allow you to create and manage events, be well as trigger payment payment processing based on the skreate’Payment-frection.

import { Web3 } from ‘@web3js/web3’;


const web3 = webs Web3();


asc functional process(event) {

    // Create a new event for the subscription

    const paymentEven = new PaymentEven();

    paymentEvent.sender = event.address;

    paymentEvent.mount = 0;

    paymentEvent.6ssage = ‘Subscript’ paid’;

    

    /// Trigger the subscription logic by calling the service provider's susbrection’

    await Subpression.serverProvider.subscribed(event.dressy.address);

}
