What is Pump.fun?

Pump.fun is a token launchpad on Solana. It lets anyone create a tradeable token in a few clicks — no code, no upfront liquidity, no listing process. Since launching in January 2024 it has become one of the largest single sources of transactions and fee revenue on the entire network, and the de facto front door for Solana's memecoin economy.

It is also, depending on who you ask, either a permissionless launch primitive or a casino. Both descriptions are fair. This explainer covers the mechanics so you can judge for yourself.

The problem it solved

Before Pump.fun, launching a token meant deploying a contract, seeding a liquidity pool on a DEX like Raydium, and hoping nobody pulled the liquidity out from under buyers (a "rug pull"). That was technical, expensive, and the rug risk was constant.

Pump.fun removed all of it. You give the token a name, ticker, and image, and you have a live, tradeable market in seconds — with liquidity that can't be yanked at launch, because of how the bonding curve works.

How the bonding curve works

Every new Pump.fun token starts on a bonding curve instead of a traditional liquidity pool. A bonding curve is just a formula: the price of the token rises automatically as more is bought, and falls as it's sold. There's no order book and no counterparty — you trade against the curve itself.

• Instant liquidity. You can always buy or sell, because the curve is the market. No one has to provide the other side.
• No launch rug. The liquidity is locked in the curve's contract, so the creator can't withdraw it to strand buyers. (This does not mean the token is safe — see the risks section.)
• Fair-ish start. Everyone buys from the same curve at the same algorithmic price. There's no pre-sale allocation by default.

"Graduation" and PumpSwap

If a token attracts enough buying to reach a target market cap (historically around $69,000), it graduates. Graduation means the accumulated liquidity migrates off the bonding curve into a real, freely-trading AMM pool, where price is set by supply and demand rather than a fixed formula.

Originally that pool was created on Raydium. In 2025 Pump.fun launched its own AMM, PumpSwap, and graduating tokens now migrate there — which keeps the trading (and the fees) inside Pump.fun's own ecosystem. Most tokens never graduate; they stall on the curve and fade. The ones that do graduate are where the attention concentrates.

How Pump.fun makes money

Pump.fun charges a small fee on trades against the curve and on PumpSwap, plus token-creation fees. Multiplied across an enormous volume of launches and trades, this has made it one of the highest-revenue applications in all of crypto, frequently out-earning much older, larger protocols on a daily basis. It has also introduced creator revenue sharing, paying a cut of trading fees back to the wallet that launched a token.

PUMP — the token

In 2025 Pump.fun ran a public sale for its own token, PUMP. It is separate from the millions of memecoins launched on the platform — PUMP is the token of the platform itself. You do not need it to create or trade tokens on Pump.fun.

The risks — read this part

• Most tokens go to zero. The vast majority of Pump.fun launches lose essentially all their value within hours or days. This is the base rate, not the exception.
• "Can't rug at launch" is not "can't rug." Creators and early buyers can still dump their holdings into your buys after graduation. The locked-liquidity protection only covers the bonding-curve phase.
• It's a speed game. Bots and insiders often buy the first blocks. Retail buyers are frequently exit liquidity.
• Nothing here is investment advice. Treat memecoin trading as high-variance entertainment with money you can afford to lose entirely.

How to think about it

Pump.fun is best understood as infrastructure, not an asset. It turned token issuance into a commodity — fast, cheap, and permissionless — which is genuinely novel and is a big part of why Solana's on-chain activity numbers are what they are. Whether the tokens launched on it are worth anything is a separate question, and the honest answer for almost all of them is "no."
