How can I import a custom address/privkey to use as my main incoming/outgoing address? If I have to modify files in order to do so that's fine.
I need a way to send/receive from the vanity address alone.
Easy with the
Mycelium Bitcoin Wallet- Install
- Swipe to Keys & Addresses
- Click +
- Click Scan (to scan the QR code with the private key)
- Click Back button
- Observe your balance, Click Send or Receive as required
The private key never leaves the Android device.
You can even delete the private key, only have the address on the device, and use the
Cold Storage Spending feature.
For improved security use a dedicated device with nothing else installed. I use a cheap second hand old Android 2.2 device, nuked to factory defaults, with cyanogenmod, no SIM.
