Checking if a Token Pays DEX Screener on Chain: A Solution for High-Volume Use Cases

As a Solana developer, you’re likely no stranger to the fast-paced world of decentralized exchanges (DEXs) and liquidity provision. However, when it comes to verifying whether a token pays DEX screener fees in real-time, the situation can be complicated. In this article, we’ll explore the limitations of traditional APIs and provide an alternative solution for high-volume use cases.

The Traditional API Approach

When using the Dex Screener API provided by Solana, you are limited to 1 request per second (req/s). This means that if you need to perform multiple checks in a short period, you will be unable to do so within the allotted time frame. This limitation makes it challenging for high-volume use cases, such as frequent token price fluctuations or large-scale trading activity.

The Solution: Using Solana’s Built-in Events

A better solution is to leverage Solana’s built-in events feature. Specifically, the solana-slip library provides an API that allows you to listen for DEX screener events on-chain. This approach enables you to receive real-time updates on token price and liquidity information without relying on traditional APIs.

Example Code: Listing a Token with Solana

To demonstrate how to use solana-slip, let’s create a simple example that lists a token using the Dex Screener API:

npm install solana-slip


// Create a new Slack client instance

const slack = require('slack');

const { Client } = require('slack');


// Set up your Slack credentials

const SlackToken = 'your-slack-token';

const SlackChannel = 'slackChannel';


// Initialize the Slack client instance

const slackClient = new Client({ token: SlackToken });


async function listToken ( ) { ) .

  // List a token using the Dex Screener API

  const dexScreenerUrl = '

  const txHash = await getDexScreenerTxHash(dexScreenerUrl);

  

  // Get the latest price of the token on-chain

  const latestPrice = await getLatestPrice( token , txHash ) ;

  

  // Send a Slack message with the latest price

  const slackMessage = {

    channel: SlackChannel,

    text: The current price of ${token} is: $${latestPrice},

  };

  

  // Post the message to the Slack channel

  await slackClient.postMessage(slackMessage);

} }


listToken ( ) ;

In this example, we create a new Slack client instance and use it to list a token using the Dex Screener API. We then receive real-time updates on the token price through Solana’s built-in events feature.

Benefits of Using Solana’s Built-in Events

The benefits of using solana-slip include:

• High-availability: Receive updates in real-time, even if the API is down or slow.

• Scalability: Perform multiple checks without relying on traditional APIs.

• Flexibility: Customizable event listeners for tailored use cases.

In conclusion, while the Dex Screener API provides a convenient way to get started with Solana’s DEX ecosystem, it has limitations when it comes to high-volume use cases. By leveraging Solana’s built-in events feature through solana-slip, you can enjoy real-time price updates and flexible event listeners without relying on traditional APIs.

Next Steps

To take your solution to the next level, consider exploring other libraries and tools that provide DEX screener functionality, such as:

• solana-liquidity-pro provider

• dex-logger

• solana-api

By combining these solutions with `solana-slip’, you’ll be able to build high-performance, on-chain DEX solutions that meet the demands of the market.
