What is Pump.fun? The Solana Bonding-Curve Launchpad Explained
Pump.fun is a Solana-based launchpad that issues new memecoins on an automated bonding curve. There is no presale and no team allocation — anyone can buy from the curve, and once the market cap reaches the graduation threshold (~$69k), liquidity is migrated to Raydium and the LP is burned.
Definition
Pump.fun is a smart-contract-based token launcher on Solana. Each launched token gets its own bonding curve — a mathematical pricing function where the price increases as more tokens are bought and decreases as they are sold — meaning the price discovers itself from the first trade with no need for a seeded liquidity pool.
How a Pump.fun launch works
- Creator picks a name, ticker, image and short description.
- The contract mints a fixed supply (1B tokens) and locks ~800M into the bonding curve.
- Anyone can buy or sell against the curve; trading fee is ~1%.
- When the curve's market cap reaches ~$69,000, the token "graduates".
- At graduation, the remaining SOL + tokens are deposited into a Raydium pool and the LP tokens are burned, permanently locking liquidity.
- After graduation the token trades on Raydium, Jupiter and is indexed by DexScreener and Birdeye.
Benefits
- Zero-friction launch: no liquidity, no team allocation, no presale.
- Fair launch model — everyone buys on the same curve from t=0.
- Automatic Raydium migration and LP burn at graduation.
- Built-in chat, transaction feed and rapid token discovery.
Risks and limitations
- 99%+ of Pump.fun launches never graduate.
- Snipers and sandwich bots dominate the first seconds of each launch.
- No room for tokenomics customization (fixed supply, fixed curve, no team allocation).
- 1% trade fee adds up for active traders.
- Bonding-curve price can move hundreds of percent on a single trade due to low depth.
Pump.fun vs MemesWorld
MemesWorld supports the same one-signature launch experience but adds a full toolkit: customizable supply and tax, optional metadata upload to Arweave/IPFS, LP lock via Streamflow, free DEX-readiness audit, indexer submission and an AI-driven promotion engine across Telegram, X and Discord. Use Pump.fun for a pure fair-launch meme; use MemesWorld when the project needs branding, audits and distribution from day one.
Frequently Asked Questions
How much does it cost to launch on Pump.fun?
About 0.02 SOL in rent + network fees, plus a 1% fee on every trade against the bonding curve.
What does "graduation" mean on Pump.fun?
Graduation is the automatic event that happens when a Pump.fun token's bonding-curve market cap reaches ~$69,000. The remaining liquidity is deposited into a Raydium pool and the LP tokens are burned, locking liquidity forever.
Can I add liquidity to a Pump.fun token before it graduates?
No. The bonding curve owns all the liquidity until graduation. After graduation it's a normal Raydium pool and anyone can add liquidity.
Is Pump.fun safe?
The contract itself has been audited and the LP burn at graduation removes the rug-pull vector. The risk is market risk: most launches die before graduating, and many tokens are deployed by snipers who dump on early buyers.
