Sealed orders fill it in the dark. At the slot the amounts are revealed, anyone opens the coin, and the whole batch buys first on pump.fun at one price.
See the slotsEvery slot is a time and a coin. Until the time, it takes sealed orders. At the time, it opens. The clocks here are real.
You pick a size and a secret. Your browser computes SHA-256(size · secret) and that hash is your order. Nobody, including us, can read the amount until you reveal it at the slot. This runs locally; the math is real.
Stored in this browser with the secret so you can reveal. Reveal opens after the slot time.
Paste any commitment, size and secret. If SHA-256 matches, the reveal is honest.
Name, ticker, time. The time must be at least an hour out so the batch can fill. At the slot, anyone can open it: the coin launches on pump.fun and every revealed order buys first, one price for all.
A coin is booked into a slot. Name, ticker and time go on the board. Nothing launches yet.
Buyers choose one of four round sizes and submit only a hash of size + secret. The board shows how many orders exist, never how big.
Each buyer reveals size + secret. The hash is checked. The batch total is now known to everyone at the same moment.
Anyone presses open. The coin launches on pump.fun and the whole revealed batch buys in one transaction, so every order gets the same price.
From there it is an ordinary pump.fun coin. The slot just decided who was first, and made sure "first" meant everyone.
If order sizes were visible, bots would size against them. A hash reveals nothing until everyone reveals together.
A launch's first seconds are usually a race. The batch turns the race into one fill.
The opener does not need to be the booker. If the booker vanishes, the slot still opens on time.
Your order cannot be revealed and is dropped at the slot. Nothing is spent. Keep the secret.
Only the count and the hashes, same as everyone.
Every slot pays a share of its first-buy fee into $ZSLOT buybacks. The amount is in the config when the keeper publishes it.
Finally live on pump.fun. The first coin to get a slot.
