Curve trading fee
Every curve buy and sell charges 100 basis points, or 1%, of the applicable gross amount. The resulting total trading fee is allocated as follows:
Creator, community, and trader shares each round down independently. The protocol receives the exact remainder, so it can receive more than 30% of a very small total fee. No curve-fee portion is left undistributed: the four integer amounts always sum to the total fee.
Post-graduation fees
The canonical Uniswap V3 pool uses fee tier10000, or 1%. That fee is charged by the pool during swaps. It is not the Cooket curve fee. When anyone calls the permanent custodian’s collectFees, the collected launch-token and ERC-20-USDC fees are sent to PermanentLPFeeVaultV3 and allocated per asset:
Again, the first three shares round down and protocol receives the exact remainder. “Collected LP fees” means amounts actually collected from the position; it does not mean LP principal, total pool volume, or fees that have accrued but have not yet been collected.
An active voluntary CTO changes only the creator payout destination. It does not change any percentage.
