Fully Noded - Join Market is a dedicated Join Market client. It works by connecting to your Join Market server remotely or locally. If you run FN-JM on a Mac you can run your Join Market server on the same machine or connect via Tor remotely. FN-JM offers full functionality as exposed by the Join Market API. This means you can initiate conjoin transactions and even earn a small return on your utxo's by turning on the "maker".
