On LocalCoinSwap, you have the ability to create a hidden trade advertisement. This is a trade advertisement that can only be visible through the URL. Other users searching through the platform's listings or viewing your profile will not be able to see this trade ad.
To use this feature to trade with a specific person, simply create a hidden ad and send them the URL of the ad.

2. Select the "Make this ad a hidden ad" toggle.
3. Click Publish Trade.
