Pump.fun (Bonding Curve)

Pump's product, pump.fun, allows users to launch and trade tokens on a bonding curve. The bonding curve product allows users to provide no upfront liquidity with price being determined by a mathematical curve.

Pump only charges a trading fee, currently 95bps on each buy and sell on a bonding curve trade. Once a token reaches around 85 SOL, the token graduates from the bonding curve and is seeded with liquidity in a PumpSwap pool. There are no fees associated with minting new tokens and graduated tokens. There used to be a 6 SOL fee for each graduated token but this fee was retired in 2025.
