Is there an easy way to get the signed raw transaction on bitcoin core, electrum wallet or any other popular wallets before or without broadcasting the transaction to the network?
Is the original query still up?
In Bitcoin Core (
GUI), adding
walletbroadcast=0 to your bitcoin.conf file will enable you to create transaction without sending it to your own mempool.
Then you can use "
Right-click->Copy raw transaction" on the particular transaction to get its RAW transaction.
