Modern Treasury is a Ruby on Rails shop
I really wouldn't want to write a service that deals with money in an unsafe language. It's so easy to make a mistake in ruby there's no compiler to help you.

I think people severely overrate the value of the language when it comes to avoiding bugs. We already know how to minimize bugs: Extensive testing regimes (automated, manual, or both) and a general focus on correctness over “shipping on an artificial deadline”.
Edit: Btw, the github.com/sorbet/sorbet project is really well run and surprisingly easy to get into. I've been drafting PRs. C++ is not nearly as rough as I remember from decades ago.
I've used Ruby in a cryptocurrency project and I've used Rust. I know there are no guarantees but I wouldn't go back to ruby. There are just too many times when the compiler catches something I missed.
