Offers & order book

Can I take only part of an offer?#

Yes. Each offer has a minimum fill set by its maker, never lower than the platform minimum of 1 QTC. A partial fill must be at least that minimum and must not leave a remainder smaller than it; if it would, take the whole remainder instead.

Each fill becomes its own trade with its own lock.

Can I cancel an offer?#

Yes, at any time. Nothing moves on-chain before a match, so cancelling only removes what is left of the offer from the book. Trades that were already matched from it continue normally.

What is a private offer?#

An offer that is not shown in the order book. It gets a secret link; whoever opens the link while signed in can take it. Use it when you have already agreed a deal with someone.

Private offers use the same escrow, the same fee and the same price guardrail. Their trades are left out of the public settlements list.

Is every sell offer in the book backed by QTC?#

It is checked, not locked. Posting a sell offer requires the amount to be available in your wallet, but nothing is moved until a match, and a wallet can be emptied afterwards.

If the QTC is no longer there at the match, the lock fails, the trade is cancelled, the offer is removed and its maker receives a warning. The buyer has been asked for nothing at that point.

How many offers can I have open?#

It depends on your rank, which only counts completed trades: rank 0 (fewer than 3 completed trades) allows 2 open offers; rank 1 (3 or more) allows 5; rank 2 (15 or more) allows 10; rank 3 (50 or more) allows 25.

Restricted accounts cannot create offers until the restriction ends.

Can I change my Arbitrum address?#

Yes, in Settings, as long as you have no open trade (with your authenticator code if two-factor is on). A trade always settles to the addresses recorded when it was matched.

There is no Quantus payout address to set: QTC you buy arrives in your platform wallet, and you withdraw from there.
