A comprehensive guide to building a professional Solana wallet tracking system that monitors transactions and delivers real-time notifications through Telegram.
In the fast-moving world of Solana trading, staying informed about wallet activities is crucial. This guide will walk you through creating a sophisticated wallet tracking bot that monitors transactions and sends detailed notifications via Telegram.
The system consists of three main components:
- Helius RPC for transaction monitoring
- MongoDB for data storage
- Telegram Bot for notifications
First, we'll create and configure your Telegram bot for notifications.
- Open Telegram and search for the @BotFather.
- Send
/newbot
command - Name your bot (Example: "super_wallet_tracking_bot")
- Save your bot token
Now we named our bot and get bot token, we need to get our chat ID.
To get your chat ID:
- Add your bot to your channel
- Send a message
- Access: https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates
- Extract the chat_id from the response
Or you can use this script to get your chat ID:
import TelegramBot from "node-telegram-bot-api";
import dotenv from "dotenv";
dotenv.config();
const TELEGRAM_BOT_TOKEN = process.env.TELEGRAM_BOT_TOKEN!;
const bot = new TelegramBot(TELEGRAM_BOT_TOKEN, { polling: true });
bot.on("message", (msg) => {
console.log("New chat ID:", msg.chat.id);
TELEGRAM_CHAT_ID = msg.chat.id.toString();
});
Add these to your .env file:
TELEGRAM_BOT_NAME = "super_wallet_tracking_bot"
TELEGRAM_BOT_TOKEN = "YOUR_BOT_TOKEN"
TELEGRAM_CHAT_ID = "YOUR_CHAT_ID"
Once we set environment variables, create a telegram.ts
file and write the following code to send messsages to Telegram:
import TelegramBot from "node-telegram-bot-api";
import dotenv from "dotenv";
dotenv.config();
const TELEGRAM_CHAT_ID = process.env.TELEGRAM_CHAT_ID!;
const bot = new TelegramBot(TELEGRAM_BOT_TOKEN, { polling: false });
export const sendTelegramMessage = async (message: string) => {
try {
await bot.sendMessage(TELEGRAM_CHAT_ID, message, {
parse_mode: "HTML",
disable_web_page_preview: true,
});
} catch (error) {
console.error("Failed to send Telegram message:", error);
}
};
Helius provides reliable RPC endpoints for Solana transaction monitoring.
Setup Steps:
- Get your Helius API key from Helius Dashboard
- Configure RPC endpoints in .env:
RPC_URL = "https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY"
WSS_URL = "wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY"
We use MongoDB for storing transaction history and analysis.
Configuration:
MONGODB_URI = "mongodb://localhost:27017/solana_wallet_tracking"
Create db.ts
file, and write the following code:
import mongoose from "mongoose";
export const connectDB = async (mongodb_url: string) => {
await mongoose.connect(mongodb_url);
console.log("π¦ MongoDB Connected");
};
Configure the wallet address you want to monitor:
WALLET_ADDRESS = "YOUR_WALLET_ADDRESS"
We need to establish communication with the Solana blockchain through Helius RPC endpoints.
Create connection.ts
file, and write the following code:
import { Connection } from "@solana/web3.js";
import dotenv from "dotenv";
dotenv.config();
const RPC_URL = process.env.RPC_URL!;
const WSS_URL = process.env.WSS_URL!;
if (!RPC_URL || !WSS_URL) {
throw new Error(
"RPC_URL and WSS_URL must be defined in environment variables"
);
}
export const connection = new Connection(RPC_URL, { wsEndpoint: WSS_URL });
This creates a Connection instance that provides:
- HTTP-based RPC calls for transaction queries
- WebSocket connection for real-time transaction monitoring
- Automatic reconnection handling
- Connection state management
The system monitors:
- Transaction signatures
- Token transfers
- Buy/Sell operations
- Amount changes
- Timestamps
We need to get transaction data from Helius RPC and processes this data and analyze signature in detail :
Create trading.ts
file, and write the following code:
import { NATIVE_MINT } from "@solana/spl-token";
import { LAMPORTS_PER_SOL, PublicKey } from "@solana/web3.js";
import { sendTelegramMessage } from "./telegram.js";
import { Trading } from "./models/Trading.js";
import { formatCryptoAddress } from "./lib/format.js";
import { connection } from "./config.js";
const explorerUrl = "https://solscan.io/tx/";
const walletUrl = `https://solscan.io/account/`;
export const subscribeTrading = (key: string) => {
const anaylzeSignature = async (log: any) => {
txn = await connection.getParsedTransaction(signature, {
maxSupportedTransactionVersion: 0,
commitment: "confirmed",
});
if (!txn) {
console.log(`Failed to fetch transaction after ${attempt} attempts`);
return;
}
// process transaction to get relevant information
console.log("preTokenBalances", preTokenBalances);
console.log("postTokenBalances", postTokenBalances);
console.log("loaced addresses", innerInstructions);
const message = `
π <b>New Transaction Detected!</b>
π <b>Wallet:</b> <a href="${walletUrl + signer}">${formatCryptoAddress(signer)}</a>
π° <b>Sol Amount:</b> ${solAmount > 0 ? "π₯ SELL" : "π€ BUY"} ${Math.abs(solAmount).(3)} SOL
πΈ <b>PNL for this Token:</b> ${totalPNL.toFixed(3)} SOL
π <b>Token:</b> <a href="${walletUrl + tokenAddress}">${tokenInfo}</a>
π <a href="${explorerUrl + signature}">View Transaction</a>
β° ${new Date().toLocaleString()}
`;
await sendTelegramMessage(message);
}
return connection.onLogs(new PublicKey(key), anaylzeSignature, "processed");
}
