is this format correct to broadcast if not can someone please help me to correct it im trying to spend a utxo of coin base

[SomberNight]

To broadcast a transaction, you need it to be in raw hex format.

• How are you trying to create this tx?
• In what format do you have the private key for that old coinbase? If you have it as a WIF key, it is easiest to use the "sweep" functionality in Electrum.

However, sweeping like that requires entering the private key on an online PC. Electrum currently does not support creating a watch-only wallet for a P2PK script, which would be necessary to offline sign a tx.
Considering it is a lot of money, if you have the WIF key, you should probably just use Bitcoin Core. Create a wallet there using the WIF key on an offline PC. Export output script descriptors and use those to create a watch-only wallet on an online PC, then create an unsigned tx on the online PC, export that and sign it on the offline PC, then broadcast the signed tx on the online PC.
