How pump.fun works, from launch to graduation

Updated 2 September 2026 · Belphor Research · the data behind this guide

Pump.fun industrialized the memecoin. Anyone can launch a token in under a minute for pennies, trading starts instantly on a bonding curve, and the platform's rules decide when a coin earns a real market. Here is the whole machine, including the failure rates the hype leaves out.

Launch: a token in under a minute

Creating a pump.fun coin takes a name, a ticker, an image, and a tiny fee. The platform mints a fixed supply, opens a bonding curve, and trading begins immediately. There is no presale allocation and no listing process; the first buyer can be anyone, including the creator. This zero-friction launch is the whole point of the platform, and the reason it produces thousands of new coins every day.

The safety defaults, and their limits

Pump.fun revokes the token's mint authority and freeze authority at creation. That matters: it removes the ability to print infinite supply and the ability to freeze holders, two of the classic rug mechanisms described in the anatomy of a rug pull. What it does not remove is every other way to take your money: creator sniping at launch, coordinated pump groups, wash-traded volume, and plain abandonment are all alive and well. Platform defaults reduce the attack surface; they do not make a coin trustworthy.

The curve stage

While on the curve, the coin's price comes from a formula rather than a pool, rising as more supply is bought. The SOL paid in accumulates as the curve's reserve. How that works, and why chart sites often show curve coins with unknown liquidity, is covered in what is a bonding curve. The practical point: curve-stage prices move violently on small flows, in both directions.

Graduation, or death

If the reserve reaches the graduation threshold, the coin migrates to a real AMM pool and becomes a normal tradable token. That is the aspiration. The statistics are brutal: the overwhelming majority of launches never graduate. They peak in their first minutes, bleed as attention moves to the next launch, and settle at effectively zero with the creator long gone. Anyone trading fresh launches is playing against those base rates, whatever the winner screenshots suggest.

The second life: takeovers

Abandonment created an unexpected market. A dead pump.fun coin still has holders, a recognizable name, and a price near zero, which makes it cheap raw material for a community willing to take it over and relaunch it. That event, the community takeover, happens through an on-chain instruction and can be detected the second it executes. It is the specific corner of pump.fun that Belphor was built around, precisely because it is a discrete, verifiable event with measurable quality signals, rather than a lottery ticket on a fresh launch.
