Faraday comes bundled in Lightning Terminal. Meaning if you have Lightning Terminal installed, you can already access Faraday through the command line and you may skip the step below. If you want to install Lightning Terminal, follow this guide.
To run Faraday, you need to be running LND from the binary releases, or compile from source with the command make install tags="signrpc walletrpc chainrpc invoicesrpc"
You can run Faraday directly from the binary releases, or compile it from source:
git clone https://github.com/lightninglabs/faraday.git
make && make install
Faraday, like bitcoind, LND and others, comes with two components: Faraday itself, and a command line interface (CLI) to interact with it. In this case, they are called faraday and frcli.
To make full use of Faraday you will need to connect it to your Bitcoin node, for example bitcoind or btcd. To do that, run Faraday with the command faraday --connect_bitcoin --bitcoin.host=localhost:8332 --bitcoin.user=[the RPC username as defined in bitcoin.conf] --bitcoin.password=[the RPC password as defined in bitcoin.conf]
If you want to run Faraday in the background, you can also write the output to /dev/null by amending &>/dev/null & to the above command.
If you are running Lightning Terminal already, either locally or remotely, Faraday will be running inside of it already. However, you will need to specify the port everytime you run frcli using the flag --rpcserver=localhost:8443, for example ./frcli --rpcserver=localhost:8443 audit
If you are a Lightning Terminal user and want to avoid having to include the --rpcserver command every time or navigating to the location of the frcli binary, you may also add an entry to your aliases file (e.g. ~/.bash_aliases):
alias frcli=’~/path/to/lit/./frcli --rpcserver=localhost:8443’
You may have to manually move over your node’s tls.cert to ~/.faraday/mainnet
To use all of Faraday’s features, we will have to configure Lightning Terminal to connect to our Bitcoin node. We can do that by amending the following lines to our lit.conf file:
faraday.bitcoin.host=[the ip or domain of our bitcoind node]:8332
faraday.bitcoin.user=[our bitcoind username, as specified in our bitcoin.conf]
faraday.bitcoin.password=[our bitcoind password, as specified in our bitcoin.conf]
Typically, bitcoind will not allow RPC connections from outside, although this can be configured with rpcallowip=[IP of the machine you are running LiT on]. If you are unsure about the security implications of opening up bitcoind’s RPC calls, consider using faraday on the same machine as your bitcoin node.
