Armory still connected to bitcoin core on my old system at that time. That isn't really being online, but I had forgotten about that. I didn't sync up to the network first, the way it looks. There were no network connections from Armory to the btc network. I created a transaction to send the balance remaining in the wallet to another address. I signed the transaction using the offline system. When I tried to broadcast it to the network, it failed. There were no connections. I have the file for the signed transaction.
So you only have the signed transaction? How about this armory wallet installed from your old PC?
If you don't have them and you only have a signed transaction there is a way to convert them to raw hex code.
Follow this guide below
- Install fresh Armory wallet on your new PC
- Open Armory
- Switch user to expert mode
- reopen the Armory wallet
- Now you should see some additional features
- Click offline transaction you should see this image below
- Load file then choose the signed transaction that you have
- Now click "Copy raw TX(HEX)"
- Go to
https://coinb.in/#broadcast- And paste the raw hex code then submit.
Let's hope if it can still broadcast old signed transaction. You don't need to be fully synced or without Bitcoin core. This one should be work if not there is nothing we can do.
