Neat! I've been discussing a similar idea for a few weeks, but my approach was to put this info in the package manager metadata.
I think one of the biggest challenges here is developing a multi-network address standard. E.g. something that could support both traditional and crypto addresses, including support for forks.
I've laid out more of my thinking in detail here: https://github.com/sustainers/discussions/issues/5
@jhabdas, I'd love to chat more with you about this (my email is in my profile)
