How to get "from" address from a coin record using full node RPC

Development

Hello, I am trying to get a transaction’s sender address using the full node RPC.

I understand you can get coin records for an address using the get_coin_records_by_puzzle_hash. How can I use the below response to figure out the sender address? The only useful info I can spot Is the parent_coin_info attribute (maybe I’m not using the correct endpoint at all).

{
      "coin":{
         "amount":32899100000000,
         "parent_coin_info":"0x0c038eaeeae1df........e481be43b952887124237b52619ba82a",
         "puzzle_hash":"0x42435e2bc2c7b4.......f1da04c847c0e3d34a6a65a35413fcc54"
      },
      "coinbase":false,
      "confirmed_block_index":31629370,
      "spent":false,
      "spent_block_index":0,
      "timestamp":1618427359
   }

But if I use the parent_coin_info with the get_coin_records_by_parent_ids endpoint, I get:

{
    "coin_records": [
        {
            "coin": {
                "amount": 32899100000000,
                "parent_coin_info": "0x0c038eaeeae1dfb4cccf47cc4ac113ba....be43b952887124237b52619ba82a",
                "puzzle_hash": "0x42435e2bc2c7b4c55c26adac1d2691ff1....c847c0e3d34a6a65a35413fcc54"
            },
            "coinbase": false,
            "confirmed_block_index": 3827370,
            "spent": false,
            "spent_block_index": 0,
            "timestamp": 1678716759
        },
        {
            "coin": {
                "amount": 26944798,
                "parent_coin_info": "0x0c038eaeeae1dfb4cccf47cc4ac113b....1be43b952887124237b52619ba82a",
                "puzzle_hash": "0x7d0eecbf113862ca5ca45167007e590....36ed6da5fd90a9dcb6071992ebd9f"
            },
            "coinbase": false,
            "confirmed_block_index": 3827370,
            "spent": false,
            "spent_block_index": 0,
            "timestamp": 1679829759
        }
    ],
    "success": true
}

Neither of these puzzle hashes resolve to the correct sender address.

I feel like I’m missing something fundamental here & I’ve been stumped for a while trying to figure this out. I’m hoping to get all transaction details within 2 requests.

Any help would be really appreciated :slightly_smiling_face:

Thanks

I assume this is a CAT token? If it’s a CAT, the puzzle hash of the parent coin is the outer puzzle hash which should not be translated to the sender address. You have to use the inner puzzle hash.

If it’s a CAT, this discussion should help.
