pump.fun is a Solana-based token launchpad that enables anyone to create and launch a new meme coin in under sixty seconds, for a creation fee of approximately 0.02 SOL. It is the most consequential infrastructure in the modern meme coin ecosystem, responsible for the vast majority of new token launches on Solana and the setting for virtually all of the trenches trading activity.
Core mechanism
pump.fun uses a bonding curve model instead of a traditional AMM or order book. When a token launches, all price discovery happens on the bonding curve: the protocol owns all liquidity, and prices are set algorithmically as a function of supply purchased. This design eliminates the traditional rug-pull vector of developer-controlled liquidity pools during the early phase, though it reintroduces it after graduation.
When a token accumulates approximately 85 SOL in its bonding curve (roughly $69,000 in market cap), it "graduates" — the accumulated SOL and a corresponding token allocation are deposited as a liquidity pool on Raydium. The token then trades on the open market like any other DEX pair.
Scale
At its peak in 2024–2025, pump.fun was launching thousands of new tokens daily and processing hundreds of millions of dollars in daily trading volume. The protocol became one of the highest-revenue applications on Solana, collecting a 1% fee on all trades. The total fees generated by pump.fun represent one of the clearest demonstrations of product-market fit in the crypto applications space.
Cultural significance
pump.fun did not merely create a token launcher — it created a new class of financial activity. The platform's accessibility and the bonding curve mechanism produced a continuous stream of short-lived speculative events, each with its own community, narrative, and price dynamic. This industrialized the meme coin lifecycle and established the conditions for the ecosystem documented across this wiki.
Criticism
Critics argue that pump.fun primarily enables low-effort scam tokens, that the platform's fees are extracted at the expense of retail traders who consistently lose money, and that the bonding curve model creates an inherently unfair information asymmetry favoring developers and insiders. The platform has responded by introducing features to detect and suppress certain types of manipulative behavior, with mixed effectiveness.
