Connect the Zap Lightning Wallet on iOS TestFlight to the RaspiBlitz over Tor

Create the Hidden Service:

• In the RaspiBlitz terminal:
  sudo nano /etc/tor/torrc

• paste on the end of the file

  HiddenServiceDir /mnt/hdd/tor/lnd_REST/
  HiddenServiceVersion 3
  HiddenServicePort 8080 127.0.0.1:8080
  

  If you want to you a different port:

  HiddenServicePort THIS_CAN_BE_ANY_PORT 127.0.0.1:8080
  

• Take note of the .onion address
  sudo cat /mnt/hdd/tor/lnd_REST/hostname

Install lndconnect

• Can install from the RaspiBlitz MOBILE menu by attempting to connect Zap in the traditional way.

• Add Go to the PATH by pasting this to the RaspiBlitz terminal:

  export GOROOT=/usr/local/go
  export PATH=$PATH:$GOROOT/bin
  export GOPATH=/usr/local/gocode
  export PATH=$PATH:$GOPATH/bin
  sudo bash -c "echo 'PATH=\$PATH:/usr/local/gocode/bin/' >> /etc/profile"
  

• Alternatively install go and lndconnect manually:

  # check if  Go is installed (should be v1.11 or higher):  
  go version 
  # If need to install Go, run these:
  wget https://storage.googleapis.com/golang/go1.13.linux-armv6l.tar.gz
  sudo tar -C /usr/local -xzf go1.11.linux-armv6l.tar.gz
  sudo rm *.gz
  sudo mkdir /usr/local/gocode
  sudo chmod 777 /usr/local/gocode
  export GOROOT=/usr/local/go
  export PATH=$PATH:$GOROOT/bin
  export GOPATH=/usr/local/gocode
  export PATH=$PATH:$GOPATH/bin
  
  # Install lndconnect:
  cd /tmp
  wget https://github.com/LN-Zap/lndconnect/releases/download/v0.1.0/lndconnect-linux-armv7-v0.1.0.tar.gz
  sudo tar -xvf lndconnect-linux-armv7-v0.1.0.tar.gz --strip=1 -C /usr/local/bin
  

Generate the lndconnect string

• Run lndconnect with the -j option to display the text string: lndconnect -j

• Edit the string: Change the IP address to the .onion address noted previously. Change the port to 8080 (or your custom port set in the torrc) delete the cert= until the macaroon= entry.

  Ends up in the format:

  lndconnect://YOUR_HIDDEN_SERVICE_ADDRESS.onion:8080?macaroon=<base64adminmacaroon>
  

Connect Zap through Tor

• Share the string to your phone in an encrypted chat message to yourself (for example).

• Paste the string into the Tor enabled Zap

• Enjoy your private and encrypted remote connection!
