this looks nice! a couple of things are left to be done:

• re-run make fmt

Thanks for your contribution!

@Fraccaman Done!

I've also created a PR to fix the command used to generate localnet files, since one of the flag values has a wrong path. https://github.com/anoma/namada/pull/3044

@McDaan Can you rebase this PR on the latest release v0.33? Alternatively, let me know if you'd be fine with me cleaning this up a bit myself.

@brentstone I'm trying to figure out how to do it correctly, but I don't want to mess up anything - so, yes, I'd be fine if you do so instead in order to avoid conflicts. Thanks :)

[McDaan]

@brentstone Done. I just gave you write access just in case I've made any mistake.
