** Creating a program for sending token information to a telegram group using Solana
In this article, we will walk through
Prerequisites
- Install Node.js (version 14 or higher) If you have already 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
Solana-ProgramLibrary. First, install it:
bash
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
`Typescript
Import * as Solanaprogram from ‘@Solana-Program’;
Const token_info_url = ‘
Const telegram_bot_token = ‘
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 marketDaTArponse = Await FetchtokenininSponse (Tokenid, Programid);
Const marketData = marketdararponse.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 FetchtokenininSponse (Tokenid: String, Programid: String) {
// Implement Your Solana Program to Fetch Token Info
Const programrogramid = solanaprogram.programid.tostring ();
Const queryargs = [
market_chart? vs_currency = USD & DAYS = 30 & Interval = Daily & Market_Data = True & Sparkline = False,
];
Const response = Await Solanaprogram.runprogram (
Programrogramid,
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);
}
}
slender ();

Sending the Token Information to a Telegram Group
Telegram Group, you’ll need to use the @Solana/Solana-Telegram-Bot-Sdk Library. First, install it:
`bash
NPM Install @Solana/Solana-Telegram-Bot-Sdk
`
Then, create another type for the telegram bot logic. Here’s 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_token = ‘
Const telegram_group_id = ‘your-telemgram-group-id’;
Export Async Function Sendtokeninfotogroup (Tokenid: String) {
Const bot = new telegrambot (
Telegram_bot_token,
{
URL: ‘https: //api.telegram.
