Pumpfun App is an independent explainer for pump.fun, a platform on Solana for launching and trading memecoins on bonding curves. It covers how a token launches, how the curve prices buys and sells, when liquidity migrates to a DEX, what it costs — and, most importantly, the serious risks.

High risk — memecoins are extremely speculative
What is pump.fun?
Pump.fun is a platform on Solana that lets anyone create a memecoin in minutes and trade it immediately against a bonding curve. There is no presale and no order book: the token launches fair, and every buy and sell interacts with a smart-contract curve that sets the price automatically.
This is an independent, informational resource and is not affiliated with or endorsed by pump.fun. Any launching or trading happens in the external app, where your Solana wallet signs each transaction.
Bonding curves explained
A bonding curve is a formula held in a smart contract that ties a token's price to how much of its supply has been bought. As buyers purchase along the curve the price rises; as they sell, it falls. No counterparty is needed — the contract itself is the market maker.
When a token's market cap reaches a set threshold, its accumulated liquidity migrates to a decentralized exchange such as a Solana AMM, and it then trades in an open pool. Until migration, all trading happens against the curve, so early price moves can be violent.
Launching a token
In the app you connect a Solana wallet such as Phantom, set a name, ticker and image, and deploy. The token launches on a bonding curve for a small fee in SOL, with no presale and no allocation to the creator beyond what they buy on the open curve like everyone else.
Launching a token is easy and cheap, which is exactly why so many exist and why quality varies wildly. A launch is not an endorsement, an audit, or a promise of value — most tokens see little or no lasting interest.
Buying & selling
To buy, connect a Solana wallet, pick a token, enter a SOL amount and confirm — the curve quotes how many tokens you receive. Selling works the same way in reverse. Every action is a signed Solana transaction, so it is non-custodial: no operator holds your keys or your coins.
Because a thinly traded curve moves sharply, a large buy can spike the price you pay and a large sell can crash the price you receive. Review the quoted amount and price impact before you confirm, and never assume you can exit at the price you entered.
Fees & costs
Trading costs are Solana network fees plus the platform's trading fee charged on each buy and sell, and creating a token costs a small amount of SOL. Solana fees are low, but the trading fee and price impact matter far more on small, fast-moving tokens.
Keep a small SOL balance set aside purely for fees, separate from what you intend to trade. Compare the token amount and price impact the curve quotes against your input before confirming any transaction.
Risks & scams
Memecoins are among the riskiest things in crypto. Read both notices below before you spend anything.
Most memecoins lose value — expect to lose your stake
Avoid scams — you never "claim" free tokens by connecting
Common problems
Most issues trace to missing SOL, a moving curve price, or connecting to the wrong site.
- No SOL for fees: keep a small SOL balance separate from your trading amount.
- Transaction failed: Solana congestion or a moved curve price can cause failures — retry with a fresh quote.
- Received fewer tokens than expected: price impact on a thin curve; reduce your buy size.
- Cannot sell at your target: a falling curve or low liquidity limits exit — there is no guaranteed exit price.
- Wrong or fake site: confirm the real app and reject unexpected approval prompts.
Pumpfun FAQ
What is pump.fun, and is this the official site?
Pump.fun is a platform on Solana for launching and trading memecoins on bonding curves. This page is an independent, informational resource and is not affiliated with or endorsed by pump.fun; any launching or trading happens in the external app.
How does a pump.fun bonding curve work?
Each token is priced by a bonding curve: a formula that rises as more supply is bought and falls as it is sold, with no order book or presale. When the market cap reaches a set threshold, liquidity migrates to a decentralized exchange for open trading.
How do I launch a token on pump.fun?
Connect a Solana wallet, set a name, ticker and image, and deploy for a small fee in SOL. The token launches on a bonding curve with no presale, and anyone can then buy or sell against the curve.
What does trading on pump.fun cost?
Solana network fees plus the platform's trading fee on each buy and sell, and a small SOL cost to create a token. Price impact on a thin curve can be large, so review the quote first.
Are pump.fun memecoins a good investment?
No memecoin is a safe or guaranteed investment. They are extremely volatile, most lose most of their value, and rug pulls and scams are common. Only risk what you can afford to lose. Not financial advice.
Do I claim free tokens by connecting a wallet?
No. Connecting a wallet does not grant free tokens. Any site promising free or guaranteed pump.fun tokens for connecting is almost certainly a scam. Buying always happens against the curve and costs SOL plus fees.
Notes before you trade
- Confirm you are on the real app and using your own Solana wallet.
- Keep a small SOL balance for fees, separate from your trade.
- Read the quoted amount and price impact; there is no guaranteed exit price.
- Never expect free "claimable" tokens for connecting — that is a scam pattern.
