Bitcoindevkit Language Bindings Dev Calls 2023

,

This post is the collection of all dev call agendas for the Bitcoin Development Kit language bindings in 2023. I host the call every second week on the BDK Discord voice channel. The live pages for these calls lives here on HackMD, but this page is a way to archive them and keep these call agendas public without relying on my keeping an active HackMD subscription.
