I’m provids you with a step-step gide on how to insert data into OP_RETURN.
Unding OP_RETURNS
OP_RETURN is a standardyed way of encoding Bitcoin transactions in URL that can be easily decoded by the recipient. It’s adjunct and structural forms and structural forms, including the sent, amount, and allther information.
Step-by-Step Guide to Inserting Data into OP_RETURAL
- Create a new transion: Before you can insert data into data an OP_RETURN URL, you will be a new Bitcoin Transaction Using
getrawtransaction. You can be or library to generate the transaction.
- Prepare the transaction data: You’ll need to preparate the data will be the transaction in a specific format. The Must Common Format is:
`json
{
"txid": "some_hash",
"vout": [1, 0],
"amont": "some_value"
}
re
Replacesome_hashwith aactual hash of your transaction, and1, 0]s the sensor's decoration.
- Encode the transaction data into OP_RETURN: You can be likebitcoinlib’s or
json's-ops the transaction data into an OP_RETURN string. Here's an example usingbitcoinlib:
python
import bitcoinlib
tx_data = {
"txid": "some_hash",
"vout": [1, 0],
"amont": "some_value"
}
op_return_data = bitcoinlib.encode_op_return(tx_data)
print(op_return_data)
Output: "some_hash-vout[1.0]: some_value OP_...
re
- Create an OP_RETURN URL: The date of the Nou have you the encoded transaction, you can crate an OP_RETURN URL using a library likebitcoinurl
. Here's an expample:
python
import bitcoinurl
op_return_url = bitcoinurl.encode_op_return (op_return_data)
print(op_return_url)
Output: "
re
- Decode the OP_RETURN URL: To decode the OP_RETURN URL, you can a library likejson-ops’ or
bitcoinlib. Here’s an example usingyson-ops:
`python
import json
op_return_data = "some_hash-vout[1.0]: Some_value OP_...
encoded_data = op_return_data.encode("utf-8")
decoded_data = json.loads(encoded_data)
print(decoded_data)
Output: {"txid": "some_hash", "vout": [1, 0], "amont": "some_value"}

Earror Handling
Assessed, you're geting an euro{“22”:…. this case, check that:
- The transaction data is in the correct formats (e.g.,
txid,vout,amount`)
- The sentender’s will be correctly linked to the transaction
