A way to trade pump.fun coins without the whole chain watching. You deposit, place orders that stay encrypted until their batch closes, and withdraw to any wallet. Each batch fills everyone at one price per coin.

A normal swap shows its coin, size and worst price before it lands. Bots use that to buy in front of you and sell into your fill. A sealed order shows nothing but a hash until the batch closes, and by then every order in the batch opens at once.

Nobody, including the operator, until the batch's drand round arrives, about forty seconds after the batch's first order. After that anyone can read it. It names a one-time key, not your wallet.

Buyers and sellers of the same coin trade with each other at the midpoint first, with no curve fee on that part. Whatever is left trades on the pump.fun curve or PumpSwap.

Your deposit is visible: the chain sees your wallet put SOL or a coin in. After that every position belongs to a key made for it alone, and withdrawals go to whatever address you choose. The link only breaks if you withdraw somewhere new.

No. Coins only leave the vault with a signature from the position's own key, and the program checks that every total the operator commits is really held. The operator can turn an order down, with the reason published, or stop running.

If no batch is committed for 48 hours, or a closed batch is left unsettled for an hour, anyone can freeze the vault. Then every position can leave with a proof rebuilt from published data, sent from any wallet. The app's "My wallet" withdrawal does exactly this.
