How to understand the pump.fun bonding curve

Why this matters

A huge share of Solana memecoins start on pump.fun. If you do not understand the curve, you will misread early price action, graduation events, and where rug risk actually lives.

Step by step

1. Grasp the pricing formula. On a bonding curve, price is a math function of how much has been bought from the curve. Each buy pushes price up the curve; each sell moves it down. There is no order book.
2. See why early buyers pay less. Because price climbs with cumulative buys, the earliest buyers get the lowest prices. This is exactly why snipers race to be first.
3. Understand pre-graduation liquidity. Before graduation, the curve itself is the liquidity. There is no separate LP for the team to pull — the main risks are concentration and snipers dumping.
4. Know the graduation threshold. When the curve fills (around a set market cap, historically ~$69k), the coin graduates: collected SOL seeds a new Raydium pool and open trading begins.
5. Reassess risk after graduation. Post-graduation, normal AMM dynamics and normal rug risk apply to the new pool. Graduation is a venue change, not a safety upgrade.
6. Set expectations realistically. Most pump.fun coins never graduate and most that do get dumped. Treat the platform's ease of launch as a reason for stricter selection, not looser.

Common mistakes to avoid

• Thinking graduation means a coin is "safe".
• Assuming early price action reflects organic demand rather than the curve plus snipers.
• Ignoring early-holder concentration on a curve launch.
• Expecting most launches to succeed.
• Forgetting that the post-graduation Raydium pool can be dumped.

Quick checklist

• ☐ Why early buyers pay less is clear
• ☐ Pre-graduation liquidity model understood
• ☐ Graduation threshold known
• ☐ Post-graduation risk reassessed
