Reviews
Trading system works flawlessly. No duplication bugs, no exploits. Exactly what I needed.
Clean UI, solid security. The trade logging is great for moderation — I can see exactly what was traded and when. Would love a webhook integration in a future update.
The atomic transaction system is exactly what I needed. Had a duplication exploit in my old trading system that cost me weeks of headaches. Zero issues with this one.
