LGTM! I'd cross out, delete, or address the nft comment in the issue since it's okay to disregard (I was wondering why it wasn't addressed in here)

Also, I suggest not using "fixes" bc the _toUint64 comment is on the other repo and merging this would close the issue

The _toUint64 fix will be covered in the N-01
