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 transferring a compressed NFT, you must return the proof and tree ID for the transaction to succeed.

Additional preparation is needed on the root of a transaction; you can check out transferAsset in our examples repository.
