Hi there. Now I will talk about what is Swingby and what for is it. It was a great and innovative project before but now it is normal to see projects like that. But swingby is one of the firsts and betters yet. It is like a crosschain between BTC and ETC. Also there is not any slippage in this platform. So you can get exactly what you have.
Making swaps procedure is so easy. You create an address, then the platform credits you in this address. I did not have enough time for checking transfer speed but the internet users' opinions are positive about that.
I think if they eant to be competetive and stay in this daily developing industry, they should add more networks. Because only BTC plays the bridge role. It is a bit outdated system.
