I would like to get a list of user addresses, that minted a native asset NFT. Is this possible? I do not want current holders of the NFT, but the original minting NFT holders.

  • Is a solution using cardano-db-sync acceptable? Oct 10, 2022 at 6:51
  • @ErikdeCastroLopo yes

Here's a way using the https://blockfrost.io API:

Fist you need to get the asset id, I assume you already have this because you know which NFT you want to look up.

Then you would query all transactions of this asset using the Cardano > Assets > Asset Transactions API endpoint:


This returns a list of transactions, where this asset has been involved.

    "tx_hash": "8788591983aa73981fc92d6cddbbe643959f5a784e84b8bee0db15823f575a5b",
    "tx_index": 6,
    "block_height": 69,
    "block_time": 1635505891
    "tx_hash": "52e748c4dec58b687b90b0b40d383b9fe1f24c1a833b7395cdf07dd67859f46f",
    "tx_index": 9,
    "block_height": 4547,
    "block_time": 1635505987
    "tx_hash": "e8073fd5318ff43eca18a852527166aa8008bee9ee9e891f585612b7e4ba700b",
    "tx_index": 0,
    "block_height": 564654,
    "block_time": 1834505492

Now you take the tx_hash of the transaction with the lowest block_height and query the Cardano > Transactions > Transaction UTxOs endpoint:


This will result in an object like this:

  "hash": "1e043f100dce12d107f679685acd2fc0610e10f72a92d412794c9773d11d8477",
  "inputs": [ ... ],
  "outputs": [
      "address": "addr1q9ld26v2lv8wvrxxmvg90pn8n8n5k6tdst06q2s856rwmvnueldzuuqmnsye359fqrk8hwvenjnqultn7djtrlft7jnq7dy7wv",
      "amount": [
          "unit": "lovelace",
          "quantity": "42000000"
          "unit": "b0d07d45fe9514f80213f4020e5a61241458be626841cde717cb38a76e7574636f696e",
          "quantity": "12"
      "output_index": 0,
      "data_hash": "9e478573ab81ea7a8e31891ce0648b81229f408d596a3483e6f4f9b92d3cf710",
      "inline_datum": "19a6aa",
      "collateral": false,
      "reference_script_hash": "13a3efd825703a352a8f71f4e2758d08c28c564e8dfcce9f77776ad1"

Go through the outputs of this object and find the one that contains your NFT in the list of amount objects. The address of this output is the original receiver of your NFT.
