Core Features of OpenTrade

OpenTrade provides a comprehensive foundation for building a functional crypto exchange with the following capabilities:

The platform supports major cryptocurrencies such as Bitcoin (BTC), Litecoin (LTC), Dogecoin (DOGE), and custom altcoins—provided they support wallet encryption through CLI tools.

Supported Trading Models

While OpenTrade primarily supports spot trading, it can be extended for more advanced use cases:

Developers can enhance functionality by integrating DeFi protocols or layer-2 scaling solutions.

Step-by-Step Installation Guide

Setting up an exchange using OpenTrade involves server provisioning, environment configuration, and secure deployment.

1. Server Setup

Use a Virtual Private Server (VPS) with the following specifications:

Create a droplet on your preferred cloud provider and log in via SSH using the credentials provided.

2. Install Dependencies

Run the following commands to prepare the environment:

sudo apt-get update
sudo apt-get install build-essential libssl-dev curl -y

Install Node Version Manager (NVM) and Node.js:

curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh -o install_nvm.sh
bash install_nvm.sh
sudo reboot
nvm install 12.6.0

3. Clone and Configure OpenTrade

Download the repository with submodules:

git clone --recurse-submodules https://github.com/3s3s/opentrade.git
cd opentrade

Navigate to the accounts server and install dependencies:

cd opentrade/accountsserver
git checkout master
cd ..
sudo npm install
sudo npm install -g forever

4. Configure Private Settings

Edit the private constants file located at ~/opentrade/server/modules/private_constants.js:

exports.recaptcha_priv_key = 'YOUR_GOOGLE_RECAPTCHA_PRIVATE_KEY';
exports.password_private_suffix = 'LONG_RANDOM_STRING1';
exports.SSL_KEY = '../ssl_certificates/privkey.pem';
exports.SSL_CERT = '../ssl_certificates/fullchain.pem';
exports.walletspassphrase = {
  'MC': 'LONG_RANDOM_STRING2',
  'BTC': 'LONG_RANDOM_STRING3',
  'DOGE': 'LONG_RANDOM_STRING4'
};
🔐 Security Note: Always replace default values, especially password_private_suffix, to prevent unauthorized access.

5. Launch the Exchange Services

Start each service using Forever for process persistence:

cd ~/opentrade/databaseServer
sudo forever start main.js

cd ~/opentrade/accountsserver
sudo forever start main.js

cd ~/opentrade/server
sudo forever start main.js

Access your exchange in the browser at https://your-domain-or-ip.

Adding New Cryptocurrencies

To list a new coin:

  1. Create a configuration file at ~/.coin/coin.conf.
  2. Example for Marycoin (~/.marycoin/marycoin.conf):
rpcuser=long_random_string_one
rpcpassword=long_random_string_two
rpcport=12345
rpcclienttimeout=10
rpcallowip=127.0.0.1
server=1
daemon=1
upnp=0
rpcworkqueue=1000
enableaccounts=1
litemode=1
staking=0
addnode=1.2.3.4
addnode=5.6.7.8
  1. Encrypt the wallet using:
./marycoin-cli encryptwallet random_long_string_SAME_AS_IN_private_constants.js
⚠️ Coins without CLI support or encryption capability (e.g., Zerocash forks) cannot be integrated.

Add Coin via Admin Panel

  1. Register as the first user (grants admin rights).
  2. Go to Admin Area → Coins → Add Coin.
  3. Fill in details including RPC credentials.
  4. Set minimum confirmations and balance thresholds.
  5. Save and test RPC connection.

If successful, the coin will appear in the wallet and trading interface.

Customizing Exchange Behavior

Modify core settings in ~/opentrade/server/constants.js:

exports.NOREPLY_EMAIL = '[email protected]';
exports.SUPPORT_EMAIL = '[email protected]';
const DOMAIN = 'yourdomain.com';
exports.TRADE_MAIN_COIN = "Marycoin";
exports.TRADE_DEFAULT_PAIR = "Litecoin";
exports.share.TRADE_COMISSION = 0.001;
exports.share.DUST_VOLUME = 0.000001;

Update chart settings in ~/opentrade/static_pages/chart.html:

const PORT_SSL = 443;
const MAIN_COIN = 'Marycoin';
const DEFAULT_PAIR = 'Litecoin';

Ensure all entries match across files for consistent behavior.

Frequently Asked Questions (FAQ)

Q: Can OpenTrade support perpetual futures or margin trading?
A: Not natively. However, developers can extend it by integrating with third-party derivatives engines or building custom matching logic.

Q: Is wallet encryption mandatory for all coins?
A: Yes. Any cryptocurrency added must support CLI-based wallet encryption. Coins like Zcash that lack this feature are incompatible.

Q: Who becomes the exchange administrator?
A: The first registered user automatically gains admin privileges, giving access to coin management, trade pairs, and site settings.

Q: How do I secure my exchange against DDoS attacks?
A: Use a reverse proxy (e.g., Nginx), enable rate limiting, implement CDN protection, and configure firewall rules on your VPS.

Q: Can I customize the frontend UI?
A: Absolutely. The frontend is built with HTML/CSS/JS and can be modified directly under /static_pages/ for branding or UX improvements.

Q: What about mobile app development?
A: While OpenTrade doesn’t include a native app, its API-first design allows easy integration with mobile clients using React Native or Flutter.
