getAssetProof

Last updated:

`getAssetProof` returns the Merkle proof for a single compressed NFT (cNFT), looked up by its Digital Asset Standard (DAS) asset ID. Compressed NFTs are not stored as individual on-chain accounts — they live as leaves in a concurrent Merkle tree, and their authenticity is established by a proof against that tree's root. This method gives you exactly that proof: the leaf, the tree's current root, and the sibling hashes along the path from the leaf to the root.

Use it whenever you need to verify or act on a compressed NFT on-chain — for example, when constructing a Bubblegum transfer, burn, or delegate instruction, which require the proof as input so the program can recompute and check the root. Pair it with [`getAsset`](./getAsset.md), which returns the asset's metadata and ownership, while `getAssetProof` returns the cryptographic proof for the same asset.

This method belongs to the `sol_das` category and requires the **basic** tier or higher. It is not available on the free tier — a free-tier key will be rejected with an authorization error.
