PumpFun launched in January 2024 and fundamentally changed how memecoins are created on Solana. Before PumpFun, launching a token required technical knowledge, upfront liquidity costs, and vulnerability to rug pulls. PumpFun changed the entire equation — and in doing so, created an ecosystem generating hundreds of millions of dollars in fees and trading volume.
Whether you want to launch a token, trade new launches, or simply understand what everyone is talking about, this guide explains how PumpFun works from the ground up.
How PumpFun Works
PumpFun uses a bonding curve pricing mechanism. Here's what that means in plain terms:
The Bonding Curve Explained
When you buy a token on PumpFun before it graduates, you're buying from the bonding curve, not from other traders. The price is determined by a mathematical formula: the more tokens have been purchased, the higher the price of the next token.
This solves the pre-sale liquidity problem that made traditional token launches vulnerable to rug pulls. The liquidity exists in the bonding curve itself — you're not trusting a developer to not pull it.
The Graduation Mechanism
Token graduation is the key event in a PumpFun token's life. When a token reaches the graduation threshold (~$69k market cap), PumpFun:
- Takes the ~85 SOL from the bonding curve
- Creates a liquidity pool on Raydium
- Burns the LP tokens (making the liquidity permanent and unremovable)
After graduation, the token trades freely on Raydium and can be listed on DEX aggregators like Jupiter. The liquidity is locked forever — there is no rug pull possible at this stage.
How to Launch a Token on PumpFun
Launching costs about 0.02 SOL (~$3 at average prices). The process takes under 2 minutes:
- Connect your Phantom or Solflare wallet to pump.fun
- Click "Launch a coin"
- Enter: token name, ticker symbol, image, and description
- Optionally buy some of your own token at launch (to avoid snipers getting everything)
- Pay the ~0.02 SOL fee and confirm
Your token is now live. The bonding curve starts, and people can begin buying immediately.
How to Evaluate PumpFun Tokens
Over 99% of tokens launched on PumpFun never graduate. Of those that do, most decline from their post-graduation peak. Finding the ones that succeed is genuinely difficult. Here are the signals traders look for:
Community Signals
- Telegram/Discord momentum: An active, organic community developing around a token in the first hour is a positive signal. Bots and fake engagement are easy to spot — look for real conversation about the token's premise.
- Twitter/X presence: Organic posts and reposts, genuine meme creation around the token concept.
- Celebrity or influencer association: Tokens associated with viral moments, celebrities, or trending topics tend to get more organic attention.
On-Chain Signals
- Buying distribution: Check that multiple wallets are buying, not just 1-3. Heavily sniped tokens (where bots bought 80%+ at launch) are high risk.
- Developer behavior: If the creator immediately sells their initial buy, treat it as a dump signal.
- Bonding curve progress: A token at 80-90% of graduation often accelerates to 100% quickly — these can be good entry points for momentum traders.

The Risks Are Real
The biggest mistakes new traders make:
- Buying tokens that are already 80%+ from their launch price on PumpFun
- Holding too long — most PumpFun tokens peak within hours of graduation
- Buying based on social media hype alone without checking on-chain data
- Not setting stop-losses or mental exit points before buying
PumpFun's Revenue and Sustainability
PumpFun charges a 1% fee on all bonding curve trades and 6 SOL at graduation. With millions of tokens launched and billions in trading volume, PumpFun has become one of the most profitable protocols in all of crypto. This revenue creates a sustainable business model — PumpFun is not going away, and will likely continue to dominate new token launches on Solana in 2026 and beyond.
