Rate · fees
Takers pay 0.10%. Launches cost $2. That's all.
Every fee the Rate contracts charge, who pays it and who receives it. Fees are taken from what the taker receives, at the moment of the fill. Network gas is separate: it goes to the chain, not to us.

How it works
- Makers pay nothing. Placing and cancelling an order already costs gas. Only the side that takes liquidity pays.
- Pool bands charge more the wider they sit. By default band 1 sits closest to the price and charges the base 0.10%; bands 2 and 3 charge 2× and 3× because they only fill once the tighter bands are used up. A pool's creator can retune its bands, but no band charges less than the base rate or more than 3%. The swap screen shows the fee before you sign.
- LPs are paid in what traders pay. Half of a band's fee goes to the LPs in that band, in proportion to their share. It vests over 10 minutes. If you withdraw before it vests, the unvested part goes to the other LPs in the band, or to the protocol if you were the last one.
- Launching costs a flat $2. It is paid in the chain's gas token (2 USDC on Arc, 0.001 ETH on RISE), and nothing is taken from the supply. Creators get no share of trading fees. Launching through an auction has no launch fee: the raise goes to the pool and the creator's treasury, with no cut to us.
Where it goes
The protocol share goes to one address set in the contracts (MatchingEngine.feeTo), operated by Digital Native Standard LTD. It is the same on every chain Rate runs on.
Risks
Pool prices can be pushed. Rate is an order-book DEX. Its pools trade at the order book's recent price, averaged over five minutes. Orders placed on the book move that price a few percent each, even if they are cancelled later. Each order is capped; the total is not.
- A pool holding only coins, with no USDC buyers behind it, can have its price pushed down and its coins bought cheap.
- A pool holding USDC can have its price pushed up and its USDC taken.
- On our contracts this took a few minutes and about $2 of gas. It applies to every pool, including a launched coin's pool after graduation. A launch's sale steps before graduation are not affected.
Before you add liquidity, look at what each side of the pool holds.
Can it change?
Yes. The contracts let us change the taker fee, the LP share and the launch fee, with no waiting period. A change applies from the next fill, never to one already settled. When it changes, this page changes with it. Every figure above can be read from the contracts at any time: MatchingEngine.feeOf, poolFeeShare, AssetGenerator.launchFee and BandPoolFactory.defaultFeeMultipliers.
