Drag through the launch window
The fee a buyer would pay at each second after launch, from the pool's fee schedule.

How they found it
Nothing had to be announced. Sniper bots watch the launch program's account writes, so a new pool is visible the moment it lands. Both bots traded through the same commercial router, FLASHX8DrLbgeR8FcfNV1F5krxYcYMUdBkrP1EPBtxB9, and each transaction paid a 0.0001 SOL tip. Bot A's transaction opens with a System Program instruction consistent with a durable nonce, which allows a transaction to be signed in advance and submitted without fetching a fresh blockhash.
What the anti-snipe fee did
The pool used a fee scheduler that starts at 99% and decays over 109 seconds. The schedule works out as follows.
| Seconds after launch | 0 | 5 | 10 | 20 | 36 | 60 | 109 |
|---|---|---|---|---|---|---|---|
| Fee | 99% | 80% | 65% | 43% | 22% | 8% | 1% |
Both bots paid an effective price 1.267 times the start price, which implies a fee of about 21%, close to the schedule at 36 seconds. The bots did not buy in the first block. They waited until the fee fell, then committed almost nothing.
What it cost them
| Bot A | Bot B | |
|---|---|---|
| Into the pool | 0.000046223 SOL | 0.000051915 SOL |
| Router tip | 0.0001 SOL | 0.0001 SOL |
| Network fee | 0.000105 SOL | 0.000105 SOL |
| Tip and fee as a multiple of the trade | 4.4 times | 3.9 times |
Each bot also paid 0.00203928 SOL in rent for its token account, which can be reclaimed. So the fee did not stop bots finding the pool. It made what they found not worth buying: together they took 516.318348 tokens, about 0.00026% of supply.
What happened next
Both positions were burned. Total supply read 199,999,483.681652 on 2 November 2026, exactly 516.318348 below the 200,000,000 minted, which equals the two buys. Mint authority is revoked, so supply can only fall.
What to take from this
If you launch on Solana, assume a bot sees your pool within the first minute, whether or not you tell anyone. A falling fee schedule is cheap protection against block-zero buying, but it only deters. It does not stop anyone arriving. Randomising the decay window, as this launch did, also makes the exact moment harder to plan around.

Questions
How do Solana sniper bots find new pools?
They subscribe to the launch program's account writes, so they see a new pool as soon as it lands, without any announcement.
What is a fee scheduler?
A pool setting that starts the trading fee very high and lowers it over a fixed time, so that buying in the first blocks is expensive.
Does an anti-snipe fee stop bots?
No. It makes early buying unprofitable. In this launch the bots waited 36 seconds and paid about 21%.
