Questions
Does a fill really leave no candle?
Yes. The trade settles between two wallets and never touches the coin's bonding curve or pool, so there is no buy or sell to chart. The token transfer itself is still on chain.
Can I cancel an order?
Any time, even while the pool is paused. Your coins or SOL come back out of escrow in the same transaction. Orders also stop filling at their expiry, 7 days by default; after that, withdraw to take everything back.
Which coins can go through the pool?
Any coin from a Solana launchpad, standard SPL or Token-2022: pump.fun, bonk.fun, believe and the rest. The program refuses Token-2022 coins with a transfer tax, a transfer hook, a permanent delegate or accounts frozen by default, because those can take or block coins sitting in escrow.
How do I open a pool for a coin that has none?
Place the first hidden order. There is no create step and no fee to open; a small rent deposit comes back when the order closes.
Is this a mixer?
No. Your SOL is never pooled or mixed: it goes straight from the buyer to a fresh wallet of yours. Ghost mode only breaks the public trail of the coin you sold.
Who can trade?
Anyone holding enough $OFF. Dev, whale or anyone else with a bag.
