House rules
How seats work, what other people can see, and what we can see.
Holding is the only way to a seat.
Each room has a minimum, set by whoever launched the coin. Hold at least that much across your linked wallets and this site shows you the link to the room's group chat in X. Seats can't be bought or handed out.
The host runs the chat.
The host made the group chat in X and gave us its invite link. We are not in the chat. We can't add anyone, we can't remove anyone, and we can't read a message.
Joining is a request in X.
The link opens the chat's invite in X, where you ask to join. The host accepts requests there. We show the link only to people who hold enough, but we can't stop someone from passing it on.
Sell and you lose the link here.
If you drop below the minimum, this site stops showing you the link and the host sees your name on a list of people who left. The host decides who stays in the chat. We read the chain twice first, so a slow or failed reading never costs you the seat.
A room can fill up.
A room has 499 seats. When it's full, someone holding at least 10 percent more than the smallest holder inside can take that seat. The host always keeps theirs.
The log shows names and never a wallet.
Each room shows who took a seat and who lost one, by name. A name is two random words unless you link an X account, and it is not made from your wallet. The log never shows a wallet address or a transaction. Trades are public on chain, so someone who compares them with the log's times can work out which wallet a name belongs to.
Your keys stay with you.
We never hold a key to your wallet. Launching a coin is one transaction, and your wallet signs it only after you've seen what it does.
Fees are named before you sign.
If a platform fee applies, the confirmation screen shows it and where it goes before your wallet asks you to sign.
Also worth knowing
Connecting a wallet is a free signature.
You sign a short message that names this site. It isn't a transaction: it moves nothing, costs nothing, and gives us no way to spend from your wallet. You can link up to 5, and what they hold is added up.
Launching is permanent.
A coin goes onto pump.fun in one transaction from your own wallet. It can't be taken back, renamed or deleted afterwards, so the launch screen shows you the details and every cost before your wallet opens.
A host's launch wallet is public.
pump.fun shows the wallet that created a coin, and the room names its host, so the two can be put together. The room also shows how much of the coin that wallet holds right now. Everyone else's wallets stay out of sight.
Leaving doesn't erase the past.
When someone leaves a chat, new messages stop reaching them. What they already received stays with them. So write in a room the way you would in any group chat.
Seats take a few minutes.
We check balances on a schedule and whenever you press check again. A seat can take a few minutes to appear or to go.
