# Fees and distribution

> Curve fees and collected Uniswap V3 LP fees without misleading simplification.

Curve trading and post-graduation Uniswap trading have separate fees and separate allocation rules.

## 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:

| Recipient bucket     | Share of total curve fee | Effective share of gross before rounding |
| -------------------- | -----------------------: | ---------------------------------------: |
| Creator payout       |                      35% |                                    0.35% |
| Community vault      |                      20% |                                    0.20% |
| Trader rewards vault |                      15% |                                    0.15% |
| Protocol treasury    |  Remainder, normally 30% |                           Normally 0.30% |

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 tier `10000`, 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:

| Recipient bucket     | Share of collected LP fees |
| -------------------- | -------------------------: |
| Creator payout       |                        25% |
| Community vault      |                        30% |
| Trader rewards vault |                        15% |
| Protocol treasury    |    Remainder, normally 30% |

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.
