- Get the SMTP server credentials for sending emails (any will do, i.e. https://www.mailgun.com/).
- Register an Infura account (https://infura.io/) and create an API key + secret.
- Register an Etherscan account (https://etherscan.io/) and create an API key.
- You will need BTC, ETH addresses and BNB, TRX addresses(optional) to collect cryptocurrency deposits (cold addresses). If you don't have it yet, you can use any multi-currency wallet like Trust Wallet and generate BTC, ETH, BNB, TRX addresses.

You need to SSH into your server as root and run the following command:
mkdir /app ;
cd /app/ || exit ;
git clone https://github.com/Polygant/OpenCEX.git ./deploy ;
cd deploy ;
chmod +x opencex.sh ;
./opencex.sh 2>&1 | tee /tmp/install.txt
Installation time ~ 5 minutes.
If something goes wrong you can clean the installation and try again
cd /app/opencex && docker compose down ;
rm -rf /app ;
docker system prune -a
🥳 Congratulations, the exchange has been successfully installed!
You can open it by your domain name.
After installation, you need to download the file /app/openex/backend/save_to_self_and_delete.txt and delete it from the server.
Mind that BTC node will take up to 30 hours to fully sync. BTC transactions sent to user addresses in this period will be collected and credited only after a full sync.
