How the fees work
Every coin launched here follows the same rules. This page explains where the trading fee goes and how to check it yourself.
What fee do traders pay?
A 0.3% hook fee on every swap, buy or sell. That is the only fee. The Uniswap v4 pool itself charges a 0% LP fee, so nothing accrues to liquidity positions, and there is no creator fee or team allocation on any coin.
Where does the fee go?
Doppler, the protocol these pools run on, keeps a fixed 5% of every hook fee. That share is hard-coded in the hook contract and cannot be turned off.
The remaining 95% is the platform fee. 100% of it goes to the treasury: fees collected in the coin are swapped into the paired coin inside the swap that generated them, and fees collected in the paired coin are transferred as they are.
How does the buy and burn work?
The treasury wallet receives paired coins from every pool on the platform. It uses all of them to buy the zkcat token on the open market and sends the purchased tokens to the burn address, which no one controls. Burned tokens are removed from circulation permanently.
The conversion into the paired coin is enforced by the pool contracts. The purchase and burn are transactions made by the treasury, so they are visible on-chain and can be checked by anyone.
Why convert to the paired coin instead of buying the platform token directly?
Coins here can be paired with anything. Converting each coin's fees into its pair first means every pool feeds the same buy and burn with liquid assets, and no coin's own liquidity is ever sold into or removed. It also keeps the on-chain rule identical for every coin, whatever it is paired with.
Does any of this go to the coin's creator?
No. Creators receive no fee share and no token allocation. The full 1,000,000,000 supply of every coin is placed on the curve at launch.
What does “liquidity locked forever” mean?
Each coin's liquidity sits in Doppler multicurve positions that are locked in the initializer contract and never migrate. There is no governance that can withdraw it and no migration step. Trading continues on the same pool indefinitely.
Can the fee routing change?
The treasury address is the only account allowed to update a pool's fee routing, and any change is an on-chain transaction on the hook contract. The fee rate, the Doppler share, and the locked liquidity cannot be changed by anyone.
How can I verify it?
Open any coin page and read the “Fees →” tile: it shows the destination stored in the pool. Then check the addresses below on Blockscout. Paired coins arrive at the treasury from the hook contract, and the zkcat token leaves the treasury for the burn address.
