Anti-Snipe
Limits early buys and adds a launch fee that fades away
Protection · keep bots and whales in check~850 gas a swap
For the first seconds of public trading, the pool sells at most a small share of the supply each second, across all buyers, and every buy pays an extra fee that drops to zero by the end. With an Allowlist Phase, it starts when the phase ends. Snipers can still buy, but they pay more and get less.
How it works on-chain
- 1Its window opens when trading does, the second after launch, or when the Allowlist Phase ends if there is one. It lasts the seconds you set, from 5 seconds to 10 minutes.
- 2Every buy in the window pays a launch fee that starts at your rate, up to 50%, and falls in a straight line to the normal fee by the end. A buy pays whichever is higher, the launch fee or the normal fee.
- 3The whole pool sells at most your cap, 0.1% to 5% of the supply, in any one second, counted across every buyer. A buy that would take the second's total over the cap is refused, so splitting a buy or using many wallets doesn't get round it.
- 4The creator's dev buy at launch pays the launch fee and counts toward the cap like any other buy.
- 5The launch fee above the pool's base fee goes all to Captain Hook, not to the creator, so the creator's own early buys pay it in full like everyone's.
What it doesn't do
It makes sniping costly rather than impossible: early buys still go through, but they pay the launch fee and stay within the cap.
