### Connect the Zeus Lightning Wallet on Android to the RaspiBlitz over Tor

This guide is heavily based on: https://github.com/seth586/guides/blob/master/FreeNAS/wallets/zeusln.md.

Tested on the RaspiBlitz v1.1 with Tor installed already.

Have a look at the proposal of @seth586 about connecting light wallets through Tor: https://medium.com/@seth586/neutrino-can-be-dangerous-so-lets-grow-bitcoins-immunity-with-a-bip-bolt-2135956f147


Download the Zeus app, APKs available here: https://github.com/ZeusLN/zeus/releases, 
on F-Droid and Google Play.

Log in to your RaspiBlitz through ssh.

Edit `torrc` with `sudo nano /etc/tor/torrc` and add the following lines (`myandroid` can be unique):
```
HiddenServiceDir /mnt/hdd/tor/lnd_api/
HiddenServiceVersion 2
HiddenServiceAuthorizeClient stealth myandroid
HiddenServicePort 8080 127.0.0.1:8080
HiddenServicePort 10009 127.0.0.1:10009
```
Save (Ctrl+O, ENTER) and exit (Ctrl+X)

Restart Tor:
```
$ sudo systemctl restart tor
```

View the private credentials of your new hidden service. The first part is the onion address, the second part is the secret.
```
$ sudo cat /mnt/hdd/tor/lnd_api/hostname
z1234567890abc.onion AbyZXCfghtG+E0r84y/nR # client: myandroid
```

Download Orbot for Android. https://guardianproject.info/apps/orbot/

Open Orbot. Click the `⋮`, select `hidden services ˃`, select `Client cookies`.

Press the + button on the lower right. Type in the the onion address and secret cookie you revealed with `sudo cat /mnt/hdd/tor/lnd_api/hostname`.  
 Must enter onion address and add .onion to end in address area.  
For the cookie you
need all the information including [cookie] # client : [client]  
 So for example:AbyZXCfghtG+E0r84y/nR # client: myandroid

Go back to Orbot's main screen, and select the gear icon under `tor enabled apps`.  
Add `Zeus`, then press back.  
Click `stop` on the big onion logo.  
Exit orbot and reopen it. Turn on `VPN Mode`.  
Start your connection to the Tor network by clicking on the big onion (if it has not automatically connected already)


Make sure Go is installed (should be v1.11 or higher):  
```
$ go version 
```
If need to install Go, run these:

```
$ wget https://storage.googleapis.com/golang/go1.11.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](https://github.com/LN-Zap/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 LND connect URI QR code:  
It will be a big QR code so maximize your terminal window and use CTRL - to shrink the code further to fit the screen

```
$ lndconnect --lnddir=/home/admin/.lnd --host=z1234567890abc.onion --port=8080
```
Scan it with Zeus and you are done.
