-## Video 2: Talking to the gm testnet (2025-09-25)
-
-- 
-
-### Adding hz as a dependency
-
-- [`hakuzaru`](https://git.qpq.swiss/QPQ-AG/hakuzaru/) is our Erlang
-  \[application\] (applications are the subset of what in another language you
-  would call "libraries" that spawn processes, essentially...) for talking to
-  the blockchain from an Erlang application.
-
-```
-$ zx list versions hakuzaru
-0.6.1
-0.6.0
-0.5.2
-0.5.1
-0.5.0
-0.4.0
-0.3.2
-0.3.1
-0.3.0
-0.2.0
-0.1.0
-$ zx set dep otpr-hakuzaru-0.6.1
-```
-
-If we just try to use this naively, we will run into errors whenever we try to
-call code that calls into hz's dependencies.
-
-So we also have to manually include all of hz's dependencies.
-
-Thankfully, hz is also subject to this same constraint, so we only have to just
-copy them from hz's zomp.meta file.
