Slipstream Fee Mechanics

Slipstream splits total swap fees into staked and unstaked components using the splitFees function, directing the staked portion to gaugeFees for LP rewards while leaving the unstaked portion for standard position fee growth accounting.

Slipstream updates feeGrowthGlobal during swap events to track accumulated fees per unit of liquidity, which subsequently determines individual position fees owed through fee growth calculations for both staked and unstaked LP positions.

You calculate Slipstream fee distributions by multiplying the total swap fee by the staked liquidity percentage to find the gaugeFees amount, then allocating the remainder to unstaked liquidity fee growth.

Slipstream gauge distribution applies primarily to staked LP positions by allocating gaugeFees as rewards, while unstaked LP positions receive their share through standard feeGrowthGlobal updates and position fees owed calculations.

Implementing Slipstream fee logic requires Solidity functions including splitFees for dividing total swap fees, gaugeFees for reward allocation, and position fee growth calculations to track fees owed accurately.
