How the Pump.fun launchpad works and its real risks
Most trending pump fun crypto tokens start life on Pump.fun, a Solana launchpad where anyone can create a memecoin for free and trade it at once on a bonding curve. When the curve sells out, liquidity moves automatically to its own exchange, PumpSwap.
That same free, instant setup is what makes Pump.fun’s coins so cheap to abuse.
The mechanics below come from Pump.fun’s own documentation, and the on-chain figures from Bitquery measurements published in September 2026. This is general information, not investment advice.
From free launch to PumpSwap, step by step
- You connect a Solana wallet, pick a name, ticker and image, then sign one transaction. Pump.fun charges 0 SOL to create, and the name, symbol and image cannot be changed afterwards.
- The program mints a fixed supply of one billion tokens. Price comes from two virtual reserves multiplied into a constant, so every buy pushes the price up and every sell pushes it down.
- Pump.fun’s docs describe a market-cap threshold. Bitquery’s on-chain reading is more exact: the coin completes when 793.1 million tokens have been sold off the curve.
- The pool migrates in one transaction to PumpSwap, with a 0.015 SOL graduation fee. Pump.fun says the step is automatic and irreversible, with no human involved.

Bonding curve vs PumpSwap pool
| Feature | On the bonding curve | After graduation (PumpSwap) |
|---|---|---|
| Who sets the price | Curve math, no order book or market makers | Pool reserves in the canonical pool |
| Total trading fee | 1.25% | 1.25% under 420 SOL market cap, falling in steps to 0.30% above 98,240 SOL |
| Creator’s share | 0.30% of every trade | 0.95% in the 420 to 1,470 SOL tier, falling to 0.05% at the top |
| Liquidity | Curve reserves | Owned by the protocol; Pump.fun neither adds nor removes it |

Why rug pulls cost almost nothing here
The classic rug, where a team pulls the liquidity pool, does not fit the design. The curve is the liquidity, and after graduation the pool belongs to the protocol.
The rug on Pump.fun is simpler. A creator, or wallets they control, buys at the bottom of the curve and sells into the wave of buyers that follows. Because every sell lowers the price, late buyers absorb the drop.
Creating a coin is free, so a failed launch costs the creator only network fees. One person can spin up coin after coin until one catches. The creator also earns 0.30% of all curve volume whether the coin survives or not.
Our guide to rug pull red flags covers the wallet and holder checks that catch this pattern.
What the on-chain numbers show
Bitquery followed each day’s launches forward instead of dividing graduations by launches. Of 38,835 tokens created on 13 August 2026, just 2.69% ever reached PumpSwap. Four cohorts landed between 2.60% and 3.10%.
The winners move fast. The median graduate cleared the curve two minutes after its first trade, so by the time a coin trends on social media, the cheap part of the curve is usually gone.
Much of the activity you see is automated. In the week to 2 September 2026, a single wallet made 17.19% of every bonding-curve trade, with a median fill of $2.40.
Watch the tickers too. Bitquery found PumpSwap tokens trading as AAPL, NVDA and OPENAI, and none are issued by those companies.

Pump.fun crypto FAQ
Is Pump.fun safe to use?
Pump.fun itself works as documented: trades follow the curve math and graduation is automatic. The risk sits in the coins. Anyone can launch one for free, so most are low-effort or built to be sold into, and Bitquery measured roughly 97% never leaving the curve.
What happens when a Pump.fun coin graduates?
Once 793.1 million tokens are sold off the curve, the remaining SOL and tokens move in one transaction to a PumpSwap pool. Pump.fun charges 0.015 SOL for the step, and afterwards the coin trades on PumpSwap with fees that drop as its market cap grows.
Can a Pump.fun creator pull the liquidity?
Not in the classic sense. Pump.fun says graduated liquidity is owned by the protocol and it neither seeds nor removes it. A creator can still dump a large early position onto buyers, which crashes the price the same way a rug does.
