How to detect launch snipers

What launch snipers is

Launch snipers is bots that buy in the first block(s) of a launch and often dump on later buyers. Learning to detect it is about identifying it programmatically from real-time on-chain data.

The signals that matter

When you are detecting launch snipers, these are the concrete signals to focus on:

• A cluster of identical buys in the first seconds
• A large supply share taken in the opening blocks
• Aggressive priority-fee bidding
• Early holders that immediately distribute
• Concentrated first-block ownership

Where to look

You will mostly observe launch snipers in the earliest transactions and the first-block holder concentration. To detect it, go straight to these sources rather than relying on chat or hype.

To detect it: the steps

1. Define the conditions precisely so they can be measured, not eyeballed.
2. Pull the data continuously rather than at a single glance.
3. Compare against a rolling baseline to filter noise.
4. Set a threshold that rejects false positives aggressively.

The mistake almost everyone makes

Turning the read into action

Spotting it is only half the job — acting on it under time pressure is the other half. The conditions around launch snipers can change in seconds, which is why many traders pair their own reads with real-time alerts that watch continuously and ping the moment something lines up.
