Anti-Sniper Strategies for Pump.fun — Protect Your Token Launch 2025

Snipers are the biggest threat to a successful Pump.fun launch. A coordinated sniper attack in the first 10 blocks can acquire 10-15% of supply, then dump it on your community. Here's how to defend your launch.

Why Snipers Target Your Token

Snipers don't discriminate — they target every new token automatically. Bots monitor the Solana mempool and fire buy transactions within milliseconds of any new Pump.fun token. The question isn't if you'll be sniped, but how much damage they'll do.

Defense #1: Bundle in Block 0

The most effective anti-sniper strategy is filling blocks 0-1 with your own wallets. If your bundle wallets buy in block 0, external snipers can only enter at block 1 or later — by which time your wallets have the best prices. This is exactly what Jito bundles enable.

Defense #2: High Priority Fee

Your bundle transactions compete with sniper bots for block inclusion. Setting a high Jito tip (0.005-0.01 SOL) ensures your bundle displaces sniper transactions in block 0. Lower tips get pushed to block 1-2 alongside the snipers you're trying to beat.

Defense #3: LBS Mode

Using Launch + Bundle + Snipe mode means you have wallets in block 0 (bundle) AND block 1-2 (snipe). Even if external snipers get some block 1 positions, your snipe wallets are competing at the same speed. You end up with more supply than any individual sniper.

Accepting Unavoidable Sniping

Some sniping is unavoidable — extremely fast bots with co-located servers will get some block 1 positions regardless. The goal isn't zero sniping, it's minimizing sniper supply percentage. With proper bundling, you can reduce sniper acquisition to under 3% of supply.
