Creating a Program for Sending Token Information to a Telegram Group using Solana

In this article, we will walk through the steps of creating a program that fetches and sends information about specific tokens with specified details to a designated Telegram group on the Solana blockchain.

Prerequisites

  • Install Node.js (version 14 or higher) if you haven’t already.
  • Familiarity with TypeScript, JavaScript, and Python is required. If you’re new to these languages, we’ll provide explanations and examples for each language.
  • A Solana node (e.g., Solana CLI or the Solana Terminal app) set up on your local machine.

Token Fetching

To fetch token information from Solana, we will use the solana-program library. First, install it:

npm install @solana program @types/solana

Then, create a new TypeScript file for the token fetching logic. Here’s an example code snippet to get you started:

token-fetching.ts

import * as solanaProgram from '@solana-program';

const TOKEN_INFO_URL = '

const TELEGRAM_BOT_TOKE = '';

export async function fetchTokenInfo(tokenId: string) {

const programId = 'your-program-id'; // Replace with your Solana program ID

const tokenProgramAddress = '

try {

// Fetch market data for the specified token

const marketDataResponse = await fetchTokenInfoResponse(tokenId, programId);

const marketData = marketDataResponse.data;

// Extract relevant information from the market data

const marketCap = marketData.market_cap;

const volume = marketData.volume;

const liquidity = marketData.liquidity;

return {

marketCap,

volume,

liquidity,

};

} catch ( error ) {

console.error(error);

return null;

}

}

async function fetchTokenInfoResponse(tokenId: string, programId: string) {

// Implement your Solana program to fetch token info

const programProgramId = solanaProgram.programId.toString();

const queryArgs = [

market_chart?vs_currency=usd&days=30&interval=daily&market_data=true&sparkline=false,

];

const response = await solanaProgram.runProgram(

programProgramId,

programId,

queryArgs,

fetchTokenInfo,

);

// Parse the response as JSON

return response.data;

}

// Example usage

async function main() {

const tokenId = 'solana';

try {

const info = await fetchTokenInfo(tokenId);

if (info) {

console.log(Market Cap: ${info.marketCap} USD);

console.log(Volume: ${info.volume} USD);

console.log(Liquidity: ${info.liquidity} USD);

}

} catch ( error ) {

console.error(error);

}

}

main();

Sending the Token Information to a Telegram Group

To send the token information to a designated Telegram group, you’ll need to use the @solana/solana-telegram-bot-sdk library. First, install it:

npm install @solana/solana-telegram-bot-sdk

Then, create another TypeScript file for the Telegram bot logic. Here is an example code snippet:

token-fixer.ts

“`typescript

import * as solanaProgram from ‘@solana-program’;

import { TelegramBot } from ‘@solana/solana-telegram-bot-sdk’;

const TELEGRAM_BOT_TOKE = ”;

const TELEGRAM_GROUP_ID = ‘your-telemgram-group-id’;

export async function sendTokenInfoToGroup(tokenId: string) {

const bot = new TelegramBot(

TELEGRAMM_BOT_TOKE,

{
