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, 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.

Examples

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"id":1,"method":"getAssetProof","params":[],"jsonrpc":"2.0"}'
const res = await fetch("https://triport.io/sol", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "id": 1,
  "method": "getAssetProof",
  "params": [],
  "jsonrpc": "2.0"
}),
});
const data = await res.json();
import requests
resp = requests.post(
    "https://triport.io/sol",
    headers={"Authorization": "Bearer <api-key>"},
    json={"id":1,"method":"getAssetProof","params":[],"jsonrpc":"2.0"},
)
print(resp.json())
