I was outbid — where is my CRETA?

It is safe, but it is not returned automatically. Your outbid CRETA stays in the auction until you take it back.

Open the auction (it is listed under Profile → Bids), find your bid and tap Withdraw bid. Confirm it, and the CRETA returns to your wallet once the transaction goes through. It costs a small POL fee.

If you bid on several auctions and lost, each one needs its own withdrawal. Nothing expires. You cannot withdraw a bid while it is still the highest.
