Ethereum: How do I compose a transaction with OP_RETURN in Python?

to conclude a transaction with op_retuee

OP_RURUN is an effective way to create a small amount of cryptocurrency vegetation offers without spelling as a common transaction. Here is a measuring step towards Python to use an OP_RRUN.

prerequisites

  • Make sure you have installed Hushlaib and Hm libraries in your Python environment. You can use and install them: PIP Installation Hshlib Hmac

  • OP_RENE DEALS (1 KB) and maintains the maximum block size for the minimum minimum (0). Any operation or 2 ^ 64-1 bits have more than 1 KB.

has entered into a transaction with op_reture

To submit an operation for an essay, you need to generate the Heash of your entered data. Here is an example of valid OP_ren rule:

Python

Import Hashmiliib

Hmac imports from DJST

Dep opturn (data):

Convert input data to bytes

Data_bytes = Data.encode ('Utf-8')

General Sha-256 input data bag

Hash_hex = Hashlib.sha256 (Data_bytes) .Hexinigst ()

Create Hmac-SHO256 signature using input data and yourself

Sig = digest (data, hash_hex), Holshlaib 56)

Back {

"Type": OP_RTurn,

“Data”: Data,

'Hash': sig.hex (),

"Arrow": 0

}

This feature is translated as “input data” and creates Sha-256 HMAC-SHA256 using input data.

Use examples

Here is an example of how the above feature can be used to enter into a transaction with an OP_RURURURURURURUK:

`Python

DATA = "My Ethereum Address: 0x2345789896969696969696969696969696969696969696969696969696969696969696969696969699969

Transaction = OP_REREE (Data)

Print (transaction)

output: {type: 'type': 'opturn', ...}

Remember that this is just an example, you should always confirm the input data to create surgery.

Management error

Remember that the OP_renren transactions contain (1 kb) and value (2 ^ 64-1 bytes). If your operation exceeds these boundaries or contains incorrect data, it will be rejected. Be sure to properly handle errors and use this function for legal purposes.

###’S conclusion

OP_RUNDT is a small way to create a small amount of cryptopic transactions when hand shared by hand as a regular transaction. By generating valid OP_ren control using Python, you can create effective and safe operations. Always remember to confirm the input data before making surgery. Happy ccodance!
