Our service also only requires one confirmation, but sometimes you may need to wait an additional couple minutes.
💎 In addition, we plan to release updates in the near future that will expand the exchange capabilities.
I noticed some delay after completing 1 Bitcoin confirmation (enough for 2 or 3 confirmations). I don't know if this is a coincidence or part of the platform's programming, but 1 confirmation is enough in the case of Bitcoin and makes exchange process faster.
