How pump.fun works, explained from its own documents, the blockchain and court records. Independent and unofficial: we are not pump.fun.
pump.fun is a Solana app where anyone can create a memecoin for free. Each coin first trades on a price curve, then moves to pump.fun's own exchange, PumpSwap, once the curve sells out. In the 30 days to November 4, 2026, DefiLlama counted $159M in fees across pump.fun's products and 74.6% of all Solana launchpad fees. Start with what pump.fun is, then the bonding curve and graduation. Most memecoins lose most of their value.

- The pump.fun Platform Fee, explainedSince 17 October 2026 every trade in the pump.fun app or website pays a 0.45% Platform Fee, or 0.40% with a referral code. Where it applies, where it doesn't, where it goes.
- pump.fun's two referral programs, side by sidepump.fun runs two referral programs: a share of the 0.45% Platform Fee, and a separate $50 deposit match. Who qualifies, what each pays, and the rules.
