Based on cursory glance of https://github.com/retrnull/garnet and review of kind 1814 notes and kind 0 profile of common 1814 testers...
In kind 0, adding a field for `cryptocurrency_addresses` where there value is an object whose fields are cryptocurrency types (e.g. `bitcoin`, `monero`, `arrr`) and value is a corresponding address for that type.

I would recommend that the cryptocurrency type be the common ticker symbols vs english names to avoid some degree of ambiguity, or even use the coin type numbers from https://github.com/satoshilabs/slips/blob/master/slip-0044.md if restructured into array format.
For example, in kind 0, instead of this for "cryptocurrency_addresses"...
```
{"monero":"55fSXyCcqkdikrxogPb16UKN3SYhkpyH32Ge6ECkAk3PhrBbXEaNcNf3o82q6vEcaR6Hp1YWdDDA6BqUJW1FL3P5Jvo5TyD"}
```
consider...
```
{"XMR": 1"55fSXyCcqkdikrxogPb16UKN3SYhkpyH32Ge6ECkAk3PhrBbXEaNcNf3o82q6vEcaR6Hp1YWdDDA6BqUJW1FL3P5Jvo5TyD"}
```
or...
```
[[128,"55fSXyCcqkdikrxogPb16UKN3SYhkpyH32Ge6ECkAk3PhrBbXEaNcNf3o82q6vEcaR6Hp1YWdDDA6BqUJW1FL3P5Jvo5TyD"]]
```
And maybe the kind 1814 should reference the given ticker or coin type as well for correlation to expedite verification
There's no NIPs referencing kind 1814 as far as I can tell, nor pull requests in the nostr-protocol/nips repo. Strongly encourage writing a specification for this to allow for wider adoption.
