You can use the bulk cancellation feature to cancel all your active listings and offers on OpenSea on a particular chain. This feature is available for all chains supported on OpenSea, and saves gas compared to canceling individual listings or offers.
You can only cancel all listings and offers for one chain at a time.
Canceling all listings and offers

3. This will open the bottom bar. To confirm your bulk cancellation, check the box and click Confirm cancellation.
4. This will prompt a transaction in your wallet. Sign to initiate your bulk cancellation transaction.
5. Once the cancellation has been processed, you'll see a confirmation message.
