Dynamic fee
The dynamic fee prices swaps from how much the coin's own price has been moving. It is the recommended setup on every launch, and most coins run it on the values the form suggests.
Those values are a recommendation, not the model. They are what a creator gets by deciding nothing, and every one of them is theirs to change.
| Market conditions | Recommended fee |
|---|---|
| Calm, price drifting | 0.30% |
| Active, price moving fast | 0.50% |
| Volatile, price swinging hard | 1.20% |
The reading decays over roughly 10 minutes: a burst of movement raises the fee almost immediately, and it steps back down as things settle. Nothing is triggered by hand; it is computed per swap.
Why a fee that moves
A pool quotes from a formula and has no opinion about price. When the outside market moves, the pool's price is briefly stale, someone trades against it, and the difference comes out of the liquidity. That cost is the familiar one for anyone who has provided liquidity: ending up with more of what fell and less of what rose. Its size depends mostly on how far the price moved.
A flat fee is therefore wrong in both directions. In a calm market it overcharges, which pushes volume away for no reason. In a volatile one it undercharges, and the difference leaves the pool. Pricing from volatility puts the fee where the cost actually is.
Setting your own
All three values are yours at creation. The only constraints are that they stay strictly increasing — calm below active below volatile — and that none exceeds the 10% ceiling, which only a declared sniper tax window lifts.
A coin that expects thin liquidity can start higher across the board; one that wants to be cheap to trade can flatten the three towards each other. Left untouched, they are the recommended values above.
Raising them makes the coin more expensive to trade and pays its liquidity, its creator and its community more per swap. Lowering them does the reverse. The choice is permanent and shown on the coin's page.
Replacing it
A creator can drop it for a flat fee, which occupies no slot, or stack another calculator on top of it. See Fee configuration.
