Jito MEV Protection on Solana: Why Your Trades Are Getting Sandwiched

If you're trading on Solana without MEV protection, you're probably losing money to sandwich attacks.

What's a Sandwich Attack?

A bot sees your pending swap transaction, puts a buy order before yours (raising the price), lets your trade execute at the inflated price, then immediately sells after you. The bot profits; you get a worse price.

On Solana, this happens in milliseconds.

How Jito Fixes It

Jito is a modified Solana validator client that lets you submit transaction bundles directly to the block producer, skipping the public mempool.

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

// Add a Jito tip to your transaction
const tipIx = SystemProgram.transfer({
  fromPubkey: userWallet,
  toPubkey: new PublicKey('96gYZGLnJYVFmbjzopPSU6QiEV5fGqZNyN9nmNhvrZU5'),
  lamports: 10000, // 0.00001 SOL tip
});

// Submit as bundle
await jito.sendBundle([serializedTransaction]);

Key points:

• Tip amount: 10,000-100,000 lamports (0.00001-0.0001 SOL). Higher = faster inclusion.
• No public mempool: Bots can't see your transaction before it's included.
• Atomic: Either the whole bundle executes or nothing does.

Real Impact

Without Jito, a 1 SOL swap on a low-liquidity token can lose 2-5% to sandwich attacks. That's 0.02-0.05 SOL per trade in hidden costs — more than most trading fees.

Implementation

I use Jito on every trade in @solscanitbot — a free Solana trading bot on Telegram. The bot handles Jito bundling automatically so users never think about MEV.
