how it works
Pumpfun stopped being fun.
Extraction everywhere. Vamps daily. Bundles on every launch.
Where did it go wrong?
Pumpswap.
We remember when Raydium was king and the trenches felt like euphoria.
Introducing .FUN.
The original Pumpfun experience, rebuilt with upgrades and launches through @Raydium.
- Every launch goes through Raydium LaunchLab and graduates to Raydium
- Anti-vamp: the original name and ticker wears the OG badge, copies are flagged and hidden
- Anti-bundle: the dev buy lands in the launch transaction itself
- Every contract address ends in FUN
- Every buy and sell bumps, and King of the Hill is back
100% of launch platform fees buy back and burn 
$FUN. We keep 0%.
Bring the fun back.
[the steps]
- 1Sign in with your wallet
No email, no password. Your wallet signs a one-time, expiring challenge that only proves you own the address. Your profile keeps a username, bio, avatar, live SOL balance and every coin you launched.
- 2Start a new coin
Name, ticker, description and an image you upload yourself.
- 3Every address ends in FUN
Every new launch address is generated so it ends in FUN before anything is submitted, and the server re-checks it.
- 4Your dev buy lands in the launch transaction
The dev buy is bundled into the same transaction as the creation, so nobody — bundlers, bots or snipers — can get a position before the creator does.
- 5Launches and trades are real
New coins are created through Raydium LaunchLab with SOL-paired bonding curves and migrate to Raydium CPMM pools when the curve completes. Every trade is signed by your wallet; older Pump.fun coins retain their original venue. A coin only appears in the feed once the transaction is confirmed on mainnet, so the feed shows live coins, not previews.
- 6Buys and sells bump
Every confirmed buy or sell bumps a coin to the top of the feed, the same shake-and-flash you remember. Trades made for the same coin anywhere else are indexed too and share the bump.
- 7Charts and chat on every coin
Each coin page carries a live price chart, a thread for replies and a full trade list with venue, size and a link to the transaction.
- 8King of the Hill is back
The coin with the largest market cap sits at the top of the home page, where it belongs.
- 9The anti-vamp system
The first coin to use a name or ticker is the original and wears the OG badge. Lookalikes — near-miss spellings, leetspeak, trailing digits — are marked VAMP, kept out of the feed unless you ask to see copies, and shown a warning that points visitors back to the original. Browse them in the OG and Vamp sections.
[fees, in plain words]
Raydium LaunchLab sets its protocol and platform fees through its on-chain configuration. Network costs and Raydium fees are additional to the separate .FUN trading fee.
On trades made through .FUN we add a disclosed 0.1% fee, taken from the quoted trade size and collected inside the same wallet-signed transaction. Trades you place elsewhere are not charged by us — they are only indexed.
New launches use a single launch-fee allocation instead of a creator/holder split. There is no anti-bundler tax.
Launch revenue funds $FUN buybacks and burns — every burn is tracked live. Raydium protocol fees remain separate, and existing coins keep their original recipients. [fees & burns]
