# Installing and Using MarketmakerV1 (in linux or MacOS)

# BarterDEX is officially deprecated as of this writing and mm2 is under testing before public release.

This guide is intended for developers and advanced users (Linux & MacOS) only using command line interface (CLI). GUI users, get BarterDEX GUI (opens new window) . For Windows installations please refer to this guide and use this link for the binaries. (opens new window)

MarketmakerV1 is capable of working with Electrum servers. This means it is not necessary to download blockchain data to your computer. As a matter of fact, you don't need even download and run native coin wallet or daemon. Check the list of current Electrum servers here: Electrum Servers List.

If you however choose to use a native coin daemon, please make sure it is fully synced. For Komodo and other assetchains use the latest Agama installer (opens new window) or use the KomodoOcean-QT (opens new window).

For a list of currently supported native coins and instructions for the coin specific configuration file, see Supported Native Coins

You may want to back up your system or clone it after everything is synced and running correctly BEFORE you start installing coin daemons.

# Installation

# Install the following dependency packages

# Linux

sudo apt-get update
sudo apt-get install cmake git libcurl4-openssl-dev build-essential libsodium-dev

# Install nanomsg

# Linux

cd ~
git clone https://github.com/nanomsg/nanomsg
cd nanomsg
cmake . -DNN_TESTS=OFF -DNN_ENABLE_DOC=OFF
make -j2
sudo make install
sudo ldconfig

# MacOS

You'll need to install homebrew (Google how to do it)

brew install nanomsg

# Clone the SuperNET repo from github & Install

Clone the repo, checkout dev branch for latest and install.

cd ~
git clone https://github.com/jl777/SuperNET
cd ~/SuperNET/iguana/exchanges
git checkout dev
./install

# Copy the passphrase file & using seed passphrase

From the same dir in terminal type the following commands to copy the passphrase file to ~/SuperNET/iguana/dexscripts dir and add a strong 24 words seed passphrase in between "". Save your passphrase properly without changing any word or space. Same seed passphrase will always show you the same smartaddress.

cp passphrase ../dexscripts/passphrase
cd ../dexscripts
nano passphrase

Enter your passphrase:

export passphrase="<put a very strong passphrase here>"

Press CTRL+X then Y then ENTER to save the file and exit from Nano editor.

# Getting the userpass value

All these scripts are expecting a userpass file, which contains the definition of the $userpass variable (found inside scripts) to authenticate API access. This is to prevent malicious webpages from issuing port 7783 calls to steal your money. At first you may not know the value of userpass. To find out, just run the client script first (as instructed below) and then run ./setpassphrase. You will notice your userpass value at the top of output and you can copy that value and put it into ~/SuperNET/iguana/dexscripts/userpass file. If you don't, all subsequent API calls will get authorisation error.

Open a new terminal and type the following (for macOS please use the client_osx script):

cd ~/SuperNET/iguana/dexscripts
./client &
./setpassphrase
pkill -15 marketmaker

# Edit the userpass file

Now copy the userpass example file to ~/SuperNET/iguana/dexscripts dir and edit the file to save the userpass you got from the ./setpassphrase script output.

cd ~/SuperNET/iguana/exchanges
cp userpass ../dexscripts/userpass
cd ../dexscripts
nano userpass

Once done press CTRL+X then Y then ENTER to save the file and exit from Nano editor.

barterDEX is now installed in your system.

# Running MarketmakerV1

Every time you want to run MarketmakerV1 open a new terminal window and type the following:

cd ~/SuperNET/iguana/dexscripts
./client &
./setpassphrase

And, don't close it. Open a new terminal window to issue all other scripts/API calls from next. Get all available api list by typing ./help inside ~/SuperNET/iguana/dexscripts dir. You can see all scripts available for you to modify, test and use.

# Activating coins

You can run MarketmakerV1 and activate coins for trading without downloading any blockchain data, using the Electrum mode. Edit the electrum script with the list of servers you want to use. To activate your list of electrum servers from the script, in terminal use ./electrum.

Native mode is faster and you need to use native wallet running with fully synced blockchain data and your barterDEX seed passphrase imported into the wallet. Edit the enable script with coin names and run ./enable in terminal window to activate native coins for trading in barterDEX.

# Stopping kill marketmaker / Close the app

If you want to close barterDEX, issue pkill -15 marketmaker every time. This ensures all BarterDEX process is killed safely.

Check the doc: MarketmakerV1 API for more info on different API calls that barterDEX supports. e.g.: buy, sell, orderbook, balance etc. Just edit them to your liking and run them in 2nd terminal.
