pump.fun in one paragraph
pump.fun is a token launchpad on Solana that went live in January 2024. Anyone can create a token in a minute with no code, and the token immediately trades on a bonding curve inside the platform's contract. When enough has been bought, the token graduates: its liquidity moves to an automated market maker and it trades like any other Solana token. The company behind the platform sold a token of its own, PUMP, in a public sale in July 2025. PUMP is an SPL token on Solana.
How the launchpad works
- Creation. The creator sets a name, ticker and image. The full supply is minted at once and the mint authority is revoked, so no more can be created. There is no presale; every token starts on the curve.
- The bonding curve. A contract holds the tokens and the SOL paid for them. The price is a function of how many tokens have been sold, so each purchase moves it up and each sale moves it down. Early buyers pay less by construction. The platform takes a fee on every curve trade.
- Graduation. When the curve has sold its allocation and raised its target amount of SOL, the contract moves the SOL and the remaining tokens into an AMM pool. Originally that pool was on Raydium; since March 2025 graduation goes to PumpSwap, the platform's own AMM. The liquidity tokens are burned by the protocol, so the creator cannot pull the pool.
- Creator fees. Since 2025 creators receive a share of the trading fees their token generates, on the curve and after graduation.
The design removes two classic rug mechanics, minting more supply and pulling the pool, which is why it became the default place to launch a memecoin. It does not remove the others, discussed below.
The PUMP token
PUMP was sold in a public sale in July 2025, on the platform itself and through several exchanges, with some jurisdictions excluded. A share of supply went to the sale; the rest was allocated to the team, existing investors, ecosystem and community programmes under vesting. The token is a standard SPL token.
What it entitles you to is the important part. It carries no equity in the operating company and no contractual right to platform revenue. Its stated roles are governance and alignment: the operator has used revenue to buy PUMP on the open market and has talked about community programmes and an airdrop to users. None of that is enforced by the token contract. Holding PUMP means holding a token whose value depends on decisions the operator is free to change.
Buybacks as a mechanism
The platform earns fees in SOL from curve trades, PumpSwap trades and creator programmes. A buyback takes some of that revenue and buys PUMP on the market. The mechanical effect is buy pressure proportional to platform revenue, which is why the token is described as a way to hold the platform's activity. Three qualifications apply. A buyback is not a burn unless the tokens are then destroyed; tokens bought and held can be sold or distributed later. It is discretionary: the operator sets size and timing and can stop. And it is verifiable only to the extent the buying wallets are known, so check the on-chain trail rather than the announcement.
The risks
- Memecoin lifecycle. The overwhelming majority of tokens launched on the platform never graduate, and most that do lose their liquidity within days. PUMP's revenue is tied to that activity, which is cyclical: when memecoin volume on Solana falls, so does the platform's income.
- Rug patterns that survive the design. Creators buy their own token in bundled transactions at launch and sell into the buyers who follow, sniper bots front-run new curves, and copycat tokens reuse a popular name with a different mint address.
- Competition. Other launchpads with the same mechanism took market share in 2025, including one from the BONK ecosystem. The mechanism is not a moat.
- Regulatory attention. The UK regulator issued a warning and the platform blocked UK users in December 2024; class actions in the United States in 2025 argued that tokens launched on it were unregistered securities. Outcomes can affect where the platform is accessible.
How to hold PUMP
PUMP is an SPL token, so it needs a Solana wallet: Phantom, Solflare or Backpack, or a Ledger through one of them. A Solana address is a base58 string with no prefix and no memo. Two Solana specifics matter. Each token you hold needs a token account, and creating one takes a small SOL deposit to make it rent-exempt; PUMP sent to a wallet with no SOL still arrives, but that wallet cannot send anything until it holds SOL for fees. And verify the mint address from the project's official channel, since tokens named PUMP with other mints exist.
How to get PUMP without an account
PUMP has a coin page and is in the swap form. Two routes:
Through SOL:
- Open the USDT TRC-20 to SOL pair, enter the amount and your Solana address, click Swap now.
- Send exactly the shown USDT amount; one TRC-20 confirmation is enough. SOL arrives at your address.
- In the swap form, choose SOL as the source and PUMP as the destination, paste the same address, send the SOL.
Directly:
- In the swap form, choose your source asset and PUMP as the destination.
- Paste your Solana address, click Swap now, send the deposit; PUMP is paid out after the rate locks.
The SOL route leaves you with SOL in the wallet for fees and rent, which the direct route does not. To exit, choose PUMP as the source in the form, or swap PUMP to SOL in your wallet and use the SOL to USDT TRC-20 pair. The cost is the deposit's network fee plus the spread and payout network fee built into the quote.
Mistakes to avoid
- A wallet with PUMP and no SOL. It cannot move anything. Keep a little SOL in every Solana wallet you use.
- Wrong mint. Same ticker, different mint address is the standard copycat trick on Solana.
- Reading buybacks as a guarantee. They are discretionary and can end.
- Signing blindly on the platform. Use a separate wallet for launchpad activity and read what each transaction does.
