Pump the Balloon,
Pop It, Win the Pot

Balloon is a launchpad for pump.fun coins on Solana with one shared balloon on top. Creator fees from every coin launched here fill the balloon's pot, every trade on those coins pumps it, and the trade that pops it wins the whole pot. Then a new balloon goes up.

Each balloon has a secret pop point: a pump number drawn at random between 50 and 500. Trades on Balloon coins are counted in chain order, one pump each. The trade that is that pump pops the balloon, and its wallet wins the pot. The next balloon starts right after that trade.

Any buy or sell of at least 0.01 SOL on a coin launched on Balloon, on its pump.fun curve or on PumpSwap after it graduates. Smaller trades and trades by Balloon's own wallets do not count. Pumps are counted a few minutes after the trade, once every coin has been read up to that point.

Balloon's launch wallet creates every coin, so it is each coin's creator on pump.fun and pump.fun pays it the creator fees. All of those fees, from every coin, go into the live balloon's pot. The pot of a popped balloon is the creator fees of every trade from its start up to and including the trade that popped it.

Each balloon's pop point is written into a line of text before the balloon goes up, and the sha256 hash of that text is published right away, one balloon ahead. When the balloon pops, the text itself is shown. Hash it yourself: it must match the hash published before, and it names the pop point. Every pump is listed with its trade, so you can count to it.

When a balloon pops and its pot is counted, the pot is recorded as owed to the winning wallet, with the amount and the reason, and shown on the balloon's proof page. Balloon sends it from its own wallet in Phantom, and the payout is then marked paid with its transaction. Nothing is paid automatically.

Add a picture, a name (3 to 32 characters), a ticker (1 to 10 letters or digits), a description of up to 512 characters, and optional website, X and Telegram links. Connect a Solana wallet, sign in by signing a message, then sign one payment of 0.1 SOL. Balloon creates the coin on pump.fun, and it appears here once the chain confirms it, usually within seconds. From then on its trades pump the balloon.

One payment of 0.1 SOL to Balloon's launch wallet. That is the whole price. pump.fun's own cost of creating the coin, about 0.02 SOL, is paid by Balloon out of that 0.1 SOL and is never added on top.

Phantom, Solflare, Backpack or any Wallet Standard wallet. You sign in by signing a message and approve every payment in your own wallet. Balloon never sees a private key, and it holds no private key of its own wallets on its servers either.

No. Balloon adds no trading fee of its own. Traders pay pump.fun's normal fees, which pump.fun sets. The creator fee part of those fees is what fills the pot.

Yes, with the optional pre-buy, which is off by default. Right after your coin is live, the page asks you to sign your own buy in your own wallet. That buy is not paid to Balloon, and like any trade it pumps the balloon.

Every coin has a supply of 1,000,000,000 with 6 decimals. pump.fun revokes the mint authority and the freeze authority when it creates the coin, so nobody can mint more or freeze wallets. That is what the Immutable label means.

Every coin starts on pump.fun's bonding curve: 30 SOL virtual against 1,073,000,000 virtual tokens, so the opening price is about 0.000000028 SOL per token and the starting market cap is about 28 SOL. When the curve fills, the coin graduates to PumpSwap, pump.fun's own pool, and its trades there keep pumping the balloon.

On pump.fun and wherever pump.fun coins trade: PumpSwap after graduation, Jupiter, and trading apps. Every one of those trades pumps the balloon. Balloon is a launchpad, not an exchange. A launch does not guarantee demand, volume or price, and a pump does not guarantee a win.

If your payment arrives but the coin cannot be created, the launch goes on a refund list and is refunded by hand. If Balloon's launch wallet is low on SOL, a paid launch waits and is created as soon as the wallet is topped up.

Open the coin's page. Its Control tab reads the mint from Solana and shows whether the mint authority and the freeze authority are revoked, next to its market data, its bonding curve address and who launched it. Always check before you sign a trade.
