Auto-Sniping New Solana Tokens with Jito MEV Protection — Building a Telegram Sniper Bot

#solana #crypto #defi #javascript

Token Sniping on Solana

When a new token launches on Solana, the first few seconds determine everything. Bots that can detect and buy within seconds of launch can 10-100x before regular traders even see the token.

I added an auto-sniper feature to my Solana Telegram trading bot that:

Polls DexScreener every 60 seconds for newly listed Solana tokens
Auto-buys using a configurable SOL amount per snipe
Uses Jito bundles for MEV-protected, priority transaction landing
Rate-limits to 3 snipes per hour (safety)
Notifies users in real-time with buy buttons for manual action

The Jito Integration

Every swap now goes through Jito's block engine first for MEV protection:

const { JitoJsonRpcClient } = require('jito-js-rpc');
const jito = new JitoJsonRpcClient('https://mainnet.block-engine.jito.wtf/api/v1');

async function sendViaJito(serializedTx) {
  const b64Tx = Buffer.from(serializedTx).toString('base64');
  const result = await jito.sendTxn({ body: b64Tx }, false);
  return result?.result || null;
}
