Trading fees
A trader pays two things: the coin's fee, and network gas. Gas goes to the chain, not to Frontier.
On the curve
1.5% of every buy and sell, in ETH, on every coin. The rate is identical platform-wide and cannot be changed by a creator.
On a 1 ETH buy that is 0.015 ETH. The quote in the trade panel is already net of it.
Being referred by someone changes nothing for the trader: the referrer's share is taken out of the protocol's part of the fee. See Referrals.
In the pool
What a swap costs is set by the coin's creator at creation, within limits the contract enforces.
| Recommended setup | the dynamic fee, suggested at 0.30% in calm markets and up to 1.20% when the price is moving hard |
| Possible instead | a flat rate, offered at 1% by default, or the creator's own volatility steps |
| Never above | 10%, outside a declared sniper tax window |
| Protocol's cut | an incompressible 0.03% of every fee |
The one exception to the 10% ceiling is a sniper tax window: a creator can declare a higher opening fee, up to 50%, that decays to the normal fee within at most an hour after the market opens. It is visible on the coin's page and expires on its own.
Two coins can therefore charge different amounts. The coin's own page shows what it charges.
Why the fee moves on most coins
The default fee tracks volatility because providing liquidity costs more when a price is moving: the fee rises when the pool is doing the hardest work and falls back when trading should be cheap. Dynamic fee explains the mechanism.
Where it goes
The short version: on the curve, half to the creator and half to the protocol. In the pool, the share the creator assigned to liquidity providers goes to them, and the rest splits 75% to the creator and their community against 25% to the protocol. Fee split has the exact tables.
Failed trades
A trade that cancels because the price moved past the slippage tolerance costs gas and nothing else. No fee is charged on a trade that did not execute.
