Token launches. You find it thirty seconds later. Already up 40%.

That's sniping. Bot bought before you blinked.

Not someone with fast fingers. Automated script sitting on a dedicated server with a direct node connection, watching the mempool for new liquidity pools. Fires the instant one appears. Humans aren't in this race.

What the Mempool Has to Do With It

Every transaction broadcasts to the network before it confirms. Sits in a waiting area called the mempool for a moment.

Developer adding liquidity to Raydium is visible there. Before it confirms. Before the token is technically live.

Sniper bot sees it. Submits a buy with higher priority fees. Gets included in the same block or the next one. Token goes live, sniper already holds a bag at the cheapest price that will ever exist.

By the time DEXScreener picks it up and alerts start flying in Telegram groups, the sniper is already sitting on 3x waiting for someone to sell into.

The Actual Problem This Creates

Everyone who bought after the sniper paid more. Sometimes a lot more.

Sniper wallet holding 8% of supply at $0.0001 per token. You bought at $0.003. They're up 2,900%. You need a 3x just to match where they entered.

That wallet has zero reason to hold long term. No emotional attachment. No belief in the project. Just a position with an enormous profit margin and an exit strategy that involves your buy order.

Scale that across ten sniper wallets holding 35% of supply collectively. That's 35% of the float sitting in hands that will sell the moment volume appears. Not if. When.

Sniping vs Bundling

• Sniping is external. Independent bots competing with each other to be first. Developer didn't plan this. Just what happens on public blockchains.
• Bundling is internal. Developer or connected wallets coordinating to buy through multiple addresses in the same block. One entity pretending to be many buyers. Manufactured demand optics.

Both result in early supply at rock bottom prices. Bundling is worse because the team is behind it deliberately. Sniping is just the reality of launching on a public chain with a visible mempool.

What Scanners Actually Show

GMGN, DEXScreener, Rugcheck all surface sniper data now.

Number of sniper wallets. How much they hold. Whether they've sold yet.

Still holding: overhead pressure intact. Those wallets are watching price.

Already sold: risk cleared for that specific supply. Whoever bought from them is the new holder base.

Combination that should make you pause: multiple sniper wallets still holding significant percentages, mint authority active, liquidity unlocked, dev hold elevated. Every red flag stacking. That's not a coincidence. That's a setup.

Defending Against It

Partially possible. Never completely.

Some launches use max buy limits in the first few blocks. High opening tax that drops after a few minutes. Whitelist-only access at launch.

Pump.fun's bonding curve changes the dynamic somewhat. No traditional liquidity pool to snipe. Price rises gradually. Bots still get in early but the structural edge is smaller.

Private launches where the contract stays hidden until liquidity is live compress the detection window. Doesn't eliminate sniping. Just makes it slightly harder.

Public blockchain. Visible mempool. Anyone with the right infrastructure can see what's coming. That's not changing.

Sniping FAQ

Should heavy sniping stop you from buying?

Not automatically. Plenty of sniped tokens run. But knowing 30% of supply is held at near-zero cost basis changes how you should size the position and where you plan to exit. Ignoring that overhead and holding for a 10x while sniper wallets are selling into every green candle is how people get stuck.
