Get Asset Proof

Get a merkle proof for a compressed asset by its ID.

Overview

This is an essential method for transactions involving a compressed asset. For instance, when you need to transfer a compressed NFT you need to return the proof and tree id for the transaction to be successful.

There is additional preparation needed on the root for a transaction, you can check out transferAsset in our examples repository here to see how this is used.
