Editing pump.fun

**pump.fun** is a [[Solana]] memecoin launchpad, operated by UK-based Baton Corporation, where anyone can create a tradable token without supplying liquidity. PUMP is its token, sold in July 2025.[^1][^6]

## Lore
pump.fun launched in January 2024.[^2] Each coin starts on a [[Bonding curve|bonding curve]] whose price rises as people buy, so the creator supplies no liquidity. A coin that completes its curve "graduates" to a full trading pool: originally on [[Raydium]] for a 6 SOL fee, and from 2025-03-20 on pump.fun's own exchange PumpSwap, with no migration fee and a 0.25% trading fee.[^3] In the week before November 2024's livestream pause it averaged over 50,000 new coins a day.[^4]

Coins that started there include [[Goatseus Maximus]], [[Fartcoin]], [[Peanut the Squirrel]], [[Just a chill guy]] and [[Fwog]].

The PUMP public sale on 2025-07-12 sold 15% of the 1 trillion supply at $0.004 in about 12 minutes; co-founder [[Alon Cohen]] told Bloomberg it raised $600 million, at a $4 billion fully diluted value. Another 18% went in a private sale.[^1]

## Controversies
### Livestreams
In November 2024 streams on coin pages included animal cruelty and threats of self-harm; co-founder Alon acknowledged "legitimate concerns" and the feature was paused on 2024-11-25 on public-safety grounds.[^4]

### Exploit
pump.fun's post-mortem said a former employee used privileged access to drain bonding-curve funds in May 2024; about $1.9 million of roughly $45 million in curve liquidity was affected, and the team pledged to reseed affected pools.[^5]

### Lawsuits
A class action in New York, led by plaintiffs Diego Aguilar, Kendall Carnahan and Michael Okafor through [[Burwick Law]] and Wolf Popper, alleges pump.fun runs an illegal gambling operation and unregistered securities business; it names co-founders Alon Cohen, Dylan Kerler and Noah Tweedale.[^6] The July 2025 amended complaint added RICO claims and Solana and Jito defendants, and alleges pump.fun generated $722.85 million from the enterprise.[^6] These are allegations.
