I Sniped a Solana Token in 400ms — Here's the Full Tech Stack

Last week, I successfully sniped a newly launched Solana token in just 400 milliseconds. To pull off something like this, you need to understand the intricacies of Solana’s ecosystem and leverage cutting-edge tools. In this article, I’ll break down the full tech stack I used, including Jito MEV bundles, Jupiter routing, and Helius RPC. I’ll also share some code snippets and lessons learned along the way.

Why 400ms is a Big Deal

In Solana’s ecosystem, speed is everything. Transactions are processed in 400ms blocks, and new token launches can be fully sniped within that window. If you’re even 100ms late, you’re already too late. To achieve this, I had to optimize every part of the pipeline, from identifying opportunities to executing trades.

The Tech Stack

1. Jito MEV Bundles: Front-Running Made Efficient

Jito is a Solana-based MEV (Maximal Extractable Value) infrastructure provider that allows you to bundle transactions and front-run others efficiently. Unlike Ethereum’s MEV, Solana’s architecture makes it possible to execute transactions at lightning speed.

Here’s how I used Jito to snipe the token:

use jito_bundle::{Bundle, Transaction};
use solana_sdk::pubkey::Pubkey;

fn create_snipe_bundle(token_address: Pubkey) -> Bundle {
    let mut bundle = Bundle::new();
    let snipe_tx = Transaction::new_snipe_transaction(token_address);
    bundle.add_transaction(snipe_tx);
    bundle
}

async fn send_bundle(bundle: Bundle) {
    let jito_client = JitoClient::new("https://jito-api.com");
    jito_client.send_bundle(bundle).await.unwrap();
}

Key Takeaways:

• Jito bundles allow you to group transactions and send them as a single unit.
• You can prioritize your transactions to ensure they’re processed first.
• Jito’s fee market ensures your bundles have a higher chance of inclusion.

2. Jupiter Routing: Optimizing Trade Execution

Jupiter is Solana’s premier swap aggregator. It routes trades through multiple DEXs to ensure the best price and minimal slippage. For token sniping, routing is critical because liquidity is often fragmented across multiple pools.

Here’s how I integrated Jupiter into my snipe pipeline:

import { Jupiter, Route } from '@jup-ag/core';

const jupiter = new Jupiter('https://jup.ag');

async function getBestRoute(inputToken: string, outputToken: string, amount: number): Promise<Route> {
    const routes = await jupiter.getRoutes({
        inputToken,
        outputToken,
        amount,
    });
    return routes[0]; // Take the best route
}

async function executeTrade(route: Route) {
    const tx = await jupiter.swap({ route });
    await sendTransaction(tx);
}

Key Takeaways:

• Jupiter routes trades through the most efficient path, minimizing slippage.
• Use getRoutes to find the best route and swap to execute the trade.
• Always check for API rate limits—sniping requires fast, repeated calls.

3. Helius RPC: Low-Latency Blockchain Access

Helius is a Solana RPC provider optimized for low-latency and high-throughput access. For sniping, you need sub-100ms RPC latency to stay competitive.

Here’s how I configured Helius for my setup:

const { Connection } = require('@solana/web3.js');

const heliusConnection = new Connection('https://helius-rpc.com', {
    commitment: 'confirmed',
    wsEndpoint: 'wss://helius-rpc.com/ws',
});

async function monitorNewTokens() {
    heliusConnection.onProgramAccountChange(
        'TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA',
        (accountInfo) => {
            console.log('New token detected:', accountInfo.pubkey.toBase58());
        }
    );
}

Key Takeaways:

• Helius’ low-latency RPC ensures you’re the first to see new tokens.
• Use onProgramAccountChange to monitor token launches in real-time.
• Configure your connection with confirmed commitment for faster updates.

The Execution Pipeline

Here’s a step-by-step breakdown of how I snipped the token in 400ms:

1. Detection: Helius RPC detected the new token launch via onProgramAccountChange.
2. Routing: Jupiter calculated the best route for the trade.
3. Bundling: Jito bundled the snipe transaction with a high-priority fee.
4. Execution: The bundle was sent and confirmed in the same block.

Lessons Learned

1. Latency is Everything

Even a 50ms delay can make the difference between sniping a token and missing out. Optimize your setup for low latency—use Helius RPC, Jito bundles, and Jupiter routing.

2. Fee Markets Matter

Jito’s fee market ensures your bundles are prioritized. Don’t skimp on fees—paying a premium can be worth it for a successful snipe.

3. Monitor Liquidity

New tokens often have fragmented liquidity. Use Jupiter to route through the best pools and minimize slippage.

4. Test, Test, Test

Sniping is a high-stakes game. Test your pipeline extensively in devnet before going live.

Conclusion

Sniping a Solana token in 400ms is no small feat, but with the right tools and optimizations, it’s possible. By leveraging Jito MEV bundles, Jupiter routing, and Helius RPC, I was able to stay ahead of the competition and execute trades at lightning speed. If you’re looking to dive into Solana sniping, start with these tools and focus on reducing latency at every step. Happy sniping!

🚀 Try It Yourself & Get Airdropped

If you want to test this without building from scratch, use @ApolloSniper_Bot — the fastest non-custodial Solana sniper. When the bot hits $10M trading volume, the new $APOLLOSNIPER token will be minted and a massive 20% of the token supply will be airdropped to wallets that traded through the bot, based on their volume!
