Every tradepays 1%.
Each coin's pool charges a fee on every buy and sell. The coin's locker splits what it collects between the wallet that launched the coin and the platform. Launching costs nothing but gas.
What everything costs
The site doesn't add a fee of its own on top of these.
Price impact isn't a fee, but on a young coin it can cost more than all of the above. Buying a large share of a thin pool moves the price against you as you buy.
Collect creator fees
Fees wait in each coin's locker until someone collects them. Anyone can press Collect: the creator and the platform get paid either way, and whoever presses it covers the gas. Amounts are paid in both the coin and its market token.
Creator's share below is the full 60% under the split. The locker contract itself sends 10% straight to the creator's wallet at collection; the balance of the 60%, and the 30% that buys back the platform token, are settled by the platform from its side of the transfer.
The juice cuts both ways. Your coin is priced in a leveraged perpetual position: if that position is liquidated its value goes to near zero, and so does the value of everything held against it in this pool — a worthless quote token can still be swapped in, so the supply can be drained for nothing. Liquidity is locked permanently and cannot be moved to another market.
