Assuming that this is a honest plea of help, I highly advise you to post your problem here so that the community may be able to help you. As always, do not reply to any suspicious private message that you have received and if this has something to do with ongoing transactions it will be good to have the transaction ID so that we could take a look. I would probably focus only in Bitcoin for now, and I would post a separate thread for ETH support in the altcoin section of the forum[1].
In what regards bitcoin transactions you do not need to code in order to broadcast offline transactions (at least in most use cases that I can think of), so more information on what you want to do would be nice to have.
