Consider having the Error Validation Layer return metadata on the actual transfer.

Currently our error validation layer just does a bunch of checks based on specific inputs and will either error, or do nothing. This is a really great step in our process as it protects the user from making mistakes when constructing their transaction.
It could be very useful to bundle any information we either fetch, or perform some complex logic to receive, and then save that to some localized metadata object, and return it. We might be able to utilize that metadata to either:

a) Increase performance where we may repeat certain functionality.
b) Return more information to the user that may be valuable.
c) Increase capacity for more accurate debugging.
