Subject: Re: [bitcoin-dev] [Bitcoin Advent Calendar] Derivatives and Options
Precedence: list

Prayank,

I believe the p2pderivatives DLC application is still under active 
development here (single oracle):
https://github.com/p2pderivatives/rust-dlc

I was once involved in the project in a galaxy far far away but haven't 
kept up with the project.  Also, I'm a few days behind in the Bitcoin 
Advent Calendar :)

Cheers,
-Yancy
