What is Pump.fun and how it works, explained for beginners

Anyone can launch a coin on Pump.fun in about a minute, and anyone can buy it a second later. That is the whole idea: no listing application, no approval queue, nobody deciding whether your coin deserves a market. On ripr you can watch that model running all day, because ripr lists coins from Pump.fun next to other Solana launchpads and lets you trade them in the same app.

Here is what actually happens between a coin being created and its price moving.

What Pump.fun is

Pump.fun is a coin launchpad on Solana. Someone uploads a name, a ticker and a picture, pays the small network cost of creating a token, and a new coin exists on chain with its own contract address. From that second it can be bought and sold.

The unusual part is that the launchpad is also the market. Normally a brand-new token needs somebody to build a trading pool and fund both sides of it before anyone can buy. A launchpad coin skips that: it starts life with a built-in pricing mechanism, so the first buyer can arrive before the coin is a minute old.

So think of Pump.fun as two things at once, a creation tool and a venue. ripr covers both sides. New coins from Pump.fun usually turn up in ripr's new-coins list within a few seconds of launching, and nearly every one of them lands there, so you can follow launches as they happen without leaving the app.

How a Pump.fun coin is made and starts trading

That built-in pricing mechanism is a bonding curve, and it is the one idea worth understanding before you touch a launchpad coin.

A bonding curve is the pricing path a coin follows as people buy and sell it. No order book, no market maker quoting a spread. Buying pushes the price up the curve, selling lets it slide back down, and the size of each trade decides how far it travels.

Three things follow from that, and they catch out most first-timers:

1. Early and late buyers pay very different prices for the same coin.
2. A big order fills worse than a small one, because it walks further along the curve.
3. In a busy minute, the price you were quoted can be gone before you confirm.

ripr deals with that third point in the buy sheet. Auto slippage sets how much movement you will accept from how far the coin travelled in the last five minutes, between 3% and 15%, and you can set your own figure instead. ripr prepares the trade on its side, then the app checks it on your device against the amount and the slippage you chose before your own wallet signs it.

Each buy and sell on the curve carries a trading fee, and part of that fee goes to the coin's creator. That is the incentive that makes launchpads work: creators earn from activity, not from a listing fee. If curves are new to you, ripr's help centre has a short page on what a bonding curve is in simple terms.

What graduation means for a Pump.fun coin

Almost everything about a launchpad points at one event. Once enough SOL has been bought into the curve, the coin reaches its target and graduates: the curve closes and the coin moves into an ordinary trading pool. On Pump.fun that pool is PumpSwap, its own automated market maker.

After graduation the coin behaves like any other Solana token. Money sits in a pool instead of a curve, the pool charges its own trading fee, and the price comes from trades against that pool rather than from a fixed path.

ripr shows you where a coin sits in that lifecycle. On the coin page you will find its Bonding Curve progress, which updates live as the coin trades toward graduation: at 100% the coin has graduated, and below that it is still climbing. The help centre spells out what the about to graduate and graduated labels mean for you as a trader.

The gap between those two stages is wider than beginners expect. A coin still on its curve might have a couple of hundred holders and under $10,000 of liquidity behind it. A graduated one can carry a few thousand holders and a few hundred thousand dollars in its pool. Same kind of coin, two completely different markets to trade in.

How Pump.fun coins look on ripr

Launchpad coins arrive faster than anyone can read about them, so the useful question is how you find and check one. On ripr, Explore is the starting point: it lists what is trending, what has just launched and what is coming next, and it keeps your watchlists in the same place. The newest coins tab is where fresh launches appear.

The screener narrows that flow down. You can filter by launchpad, Pump.fun included, and then by market cap, liquidity or age, which is how you skip past the thousands of coins that never found a buyer. If somebody sends you a specific coin, paste its full contract address into the search box on Explore and you land on that exact coin rather than a lookalike with the same ticker.

The coin page is where the research happens. ripr shows how much of the supply the top 10 holders, the top 50 and the creator hold. Pools and vaults are left out of that count, so what you get is a quick read on whether a handful of wallets could move the price on their own.

Before you buy, ripr also shows warnings for known rug patterns, such as a creator holding unlocked liquidity, liquidity that has already been pulled, or a coordinated launch. The app says plainly that a missing warning is not a verdict. Trending, meanwhile, ranks coins on how fast trades, volume and buyers are growing, and it pushes down coins whose activity looks manipulated. Flagged coins can still turn up there, though, until you switch on the Hide warnings filter.

Trading is in the same place as the research. ripr can trade coins on the Pump.fun curve and in PumpSwap pools as well as on its own curve, and whether a particular coin is tradable depends on its pool.

What all this means when you trade a Pump.fun coin

A coin's stage tells you what kind of market you are stepping into. It tells you nothing about where the price is going. A coin three-quarters of the way up its curve is thin and twitchy by design; a graduated one with real money in its pool moves differently. Neither is a prediction.

So the beginner version of all this is short. Start with an amount you would not mind losing, and keep a little SOL spare for network fees. Read the warnings on a coin page, and remember that a quiet page only means nothing tripped a rule. Check the full contract address before you buy anything somebody linked you. Our guide on how to spot a risky meme coin goes through the rest of the checks.

Trying it yourself on ripr takes very little setup. Signing up creates a Solana wallet for your account, with no separate wallet app and no recovery phrase to write down first, and you can add money by card or Apple Pay, or by UPI and bank transfer in India. After that, open Explore, sort the newest coins, and spend a while just watching curves fill before you buy anything.

And if the creation side is what caught your interest, ripr can launch a coin on Pump.fun itself, alongside its own curve and several other Solana venues, from the launch flow.
