Hello! Is there any way to get raw_data_hex before broadcasting transaction? I

I found out that <a href="https://developers.tron.network/reference/getsignweight" rel

I found out that https://developers.tron.network/reference/getsignweight returns raw_data_hex in the response.

client = tronpy.Tron()
# pk is a variable that contains a private key object
txn = client.trx.transfer(pk.public_key.to_base58check_address(), "T_address_here", 10 * tronpy.TRX).build().sign(pk)
raw_data_bytes = bytes.fromhex(client.get_sign_weight(txn)["transaction"]["transaction"]["raw_data_hex"])

from tronpy.

Use https://github.com/bitcartcc/trontxsize to reliably calculate transaction size (there's no other way to do it in python, I imported full node's protobuf files)
But ideally, you can use BitcartCC for this, i.e. set up bitcartcc daemon via https://docs.bitcartcc.com/deployment/ or manually:

git clone https://github.com/bitcartcc/bitcart
cd bitcart
pip install -r requirements/base.txt
pip install -r requirements/daemons/trx.txt

TRX_SERVER=https://rpc.ankr.com/http/tron python3 daemons/trx.py

Then using https://github.com/bitcartcc/bitcart-sdk or https://github.com/bitcartcc/bitcart/releases/tag/cli-1.1.0 or any other language, you can do stuff like this:

from bitcart import TRX

coin = TRX(xpub="yourprivatekey")
transaction = coin.server.payto("address", amount, unsigned=True)
fee = coin.server.get_default_fee(transaction) # reliable in 100% of cases
# then sign and broadcast:
signed_tx = await coin.server.signtransaction(transaction)
tx_hash = await coin.broadcast(signed_tx)
