Set your eth_privkey to be able to relay transactions. The ETH address with that private key should be loaded up with adequate funds for market making.

You can add, remove, and configure pair settings in the pairs section.

Configuration Via Environment Variables

If your hosting service requires you to pass in configs via environment variables you can compress config.json:

cat config.json | tr -d ' ' | tr -d '\n'

and set it to the value of the MM_CONFIG environment variable to override the config file.

You can also override the private key in the config file with the ETH_PRIVKEY environment variable.
