Sniper tax
Bots buy new markets in the opening block, ahead of anyone reading about them. The sniper tax makes those first seconds expensive: the fee starts as high as 50% and decays in a straight line to the coin's normal fee over a window the creator declares.
Settings
| Setting | Range | Recommended |
|---|---|---|
| Tax amount | up to 50% | 50% |
| Duration | up to 1 hour | 10 minutes |
Ten minutes at the full rate prices the bots out of the opening and lets a real audience in almost immediately. A longer window taxes genuine early buyers for as long as it runs.
When the window starts
The sniper tax protects a pool, so its window opens when the pool does. On a bonding-curve launch that is the moment the liquidity is seeded at graduation, not when the coin is created and not when curve trading begins.
Nothing taxes the curve phase. If you want protection from the very first block your coin exists, launch it with an instant pool instead, where the market opens in the creation transaction and the window opens with it.
How it combines
The tax only ever raises the fee. It sits alongside the coin's other calculators and applies whenever its value is higher than theirs, so during the window traders pay the tax and afterwards the normal model applies untouched.
While a declared window runs, the 10% ceiling is lifted to the declared tax and only for that duration. The window is public on the coin's page from creation, so nobody discovers it by trading into it.
What it costs
The tax does not distinguish a bot from an early buyer. Both pay it, and the proceeds split like any other fee: the liquidity providers' share, then 75% creator and community against 25% protocol.
No setting separates the two groups, which is the whole argument for a short window: ten minutes costs the bots their edge and costs a genuine early buyer very little.
