I'm starting to love this guy. It's like he secretly reads my posts or something...
I was wrong before, and rightly corrected. DECRED did the atomic swap across the live blockchain, while Komodo did it using electrum. I don't really know or understand which matters more.
It'd be really cool to do atomic swaps using Tether, bypassing BTC as the altcoin reserve currency, and going straight from or to USD

One fewer psychological barrier.
