Pump.fun has launched over 7 million tokens since its January 2024 debut, according to Dune Analytics dashboards. The platform generated over 00 million in cumulative revenue by mid-2026. Understanding its bonding curve, fee structure, and graduation mechanics is essential before you trade on it. Our research methodology details how we verify on-chain data for every claim in this guide.
This article is part of our beginner guide to meme coins, which covers the broader landscape of meme coin investing.
What Is Pump.fun and How Does the Platform Work?
Pump.fun eliminates the technical barriers to token creation. There is no coding, no liquidity provision, and no upfront capital beyond a small creation fee. The creator sets the branding. The platform handles everything else: contract deployment, initial liquidity via bonding curve, and automatic graduation to Raydium.
Every token starts at the same baseline. No presale allocations, no team tokens, no venture capital rounds. The bonding curve ensures that the first buyer pays the lowest price and each subsequent purchase pushes the price higher according to a mathematical formula.
This structure was designed to solve the insider allocation problem that plagued earlier token launchpads. Whether it succeeds depends on how well you understand the mechanics, which the following sections break down.
How Do Bonding Curves Set the Price of a Pump.fun Token?
A bonding curve is a smart contract that acts as an automated market maker with a fixed mathematical relationship between supply and price. On Pump.fun, approximately 800 million tokens are available on the curve. The remaining 200 million are reserved for the Raydium liquidity pool at graduation.
Early buyers acquire tokens cheaply. As SOL flows in, the price accelerates along the curve. This creates the explosive early gains that attract meme coin traders. It also means that late buyers pay exponentially more per token than early participants.
The curve is transparent. Solscan shows every transaction in real time. You can see exactly how much SOL is in the bonding curve and calculate where on the price curve the token currently sits. There are no hidden mechanics.
What Fees Does Pump.fun Charge for Trading and Token Creation?
| Action | Fee | Paid By | When Charged |
|---|---|---|---|
| Token creation | ~0.02 SOL | Creator | At deployment |
| Buy (bonding curve) | 1% of transaction | Buyer | Each purchase |
| Sell (bonding curve) | 1% of transaction | Seller | Each sale |
| Graduation | 1.5 SOL | Deducted from pool | At graduation trigger |
| Solana network fee | ~0.00025 SOL | Transaction initiator | Every transaction |
The 1% trading fee is competitive relative to other launchpads. SunPump on Tron and Four.Meme on BNB Chain charge similar rates. The graduation fee of 1.5 SOL is fixed regardless of the token’s final market cap.
These fees add up. A round trip (buy and sell) costs 2% in platform fees alone, plus slippage and price impact. Factor this into every trade. You need the token to appreciate more than 2% just to break even.
What Happens When a Pump.fun Token Graduates to Raydium?
Graduation is the critical transition. The bonding curve closes permanently. No more buying or selling through Pump.fun’s contract. All trading moves to Raydium, where the price is set by traditional AMM mechanics: supply, demand, and liquidity depth.
The liquidity deposited at graduation is locked, according to Pump.fun’s documentation. This prevents the immediate rug pull scenario where a creator drains the pool. However, locked liquidity does not guarantee price stability. Sellers can still dump tokens on the open market.
Only a small fraction of Pump.fun tokens graduate. Dune Analytics data shows that fewer than 2% of all tokens created on Pump.fun reach the graduation threshold. The vast majority die on the bonding curve with less than 1 SOL in total volume.
What Are the Biggest Risks of Buying Tokens on Pump.fun?
Pump.fun’s fair launch structure reduces but does not eliminate insider advantage. Creators can buy their own tokens from separate wallets seconds after deployment. This practice is widespread. RugCheck and Bubblemaps can reveal wallet clustering that suggests coordinated buying.
The bonding curve itself creates an asymmetric risk profile. Early buyers have small downside and massive upside. Late buyers, especially those entering near the graduation threshold, face enormous downside if sellers dump on Raydium immediately after graduation.
My assessment: Pump.fun is a zero-sum game with negative expected value for the average participant after fees. The 2% round-trip fee and the sub-2% graduation rate mean that the platform systematically transfers wealth from late entrants to early entrants and to the platform itself. Treat any SOL you send to Pump.fun as risk capital you can afford to lose entirely.
How Do You Buy a Token on Pump.fun Step by Step?
Visit pump.fun and click “Connect Wallet” in the top right. Select Phantom. Approve the connection. If you need to set up Phantom first, follow our Phantom wallet setup guide.
Browse the token feed or paste a contract address into the search bar. The token page shows the bonding curve progress, number of holders, transaction history, and creator details. Review all of this before buying.
Enter the amount of SOL you want to spend. The interface shows your estimated token output. Click “Buy” and approve the transaction in Phantom. The swap executes against the bonding curve instantly. Check your Phantom wallet to confirm the tokens arrived.
To sell, return to the token page, switch to the “Sell” tab, enter the number of tokens or percentage of your holdings, and confirm. If the token has graduated, you sell on Raydium instead. For buying graduated tokens through a DEX aggregator, see our guide on buying meme coins on Solana.
Can I create my own token on Pump.fun?
Yes. Click “Create Token” on pump.fun, fill in the name, ticker, description, and upload an image. Pay the creation fee of approximately 0.02 SOL. The token deploys instantly with its bonding curve active. No coding or technical knowledge is required.
What happens to my tokens if Pump.fun shuts down?
Tokens on the bonding curve would become inaccessible for trading. Graduated tokens on Raydium would continue trading independently since they exist as standard SPL tokens on the Solana blockchain. The Raydium liquidity pool operates without any dependency on Pump.fun’s servers.
How do I know if a Pump.fun token is about to graduate?
The bonding curve progress bar on the token page shows percentage completion. When it approaches 100%, graduation is imminent. You can also check the SOL balance in the bonding curve contract on Solscan. Graduation triggers at approximately 85 SOL deposited.
Why did the price drop immediately after graduation?
Post-graduation dumps are common. Early buyers who accumulated tokens cheaply on the bonding curve sell into the Raydium liquidity pool to lock in profits. The initial Raydium liquidity is finite, so concentrated selling causes sharp price declines. This pattern repeats on the majority of graduated tokens.
