db:migrations_path | Path to migrations dir with sql up/down scripts. Schema is mandatory. |
db:path | Path to database file, for example: distributor-bot.db |
matrix:host | Designates the host address of the Matrix server. |
partner_plugin:host | Sets the host address for the partner plugin's RPC server. |
partner_plugin:unencrypted | Determines if the Partner Plugin RPC should establish an unencrypted connection to the server. |
partner_plugin:ca_file | Path to the CA certificate file for the partner plugin RPC server. Required only if partner_plugin_unencrypted=false |
rpc_server:port | Specifies the port number for the RPC server; the bot listens for requests on this port. |
rpc_server:unencrypted | Indicates if the RPC server communication should remain unencrypted. |
rpc_server:cert_file | File path to the server's TLS certificate for encrypted communication. Required only if rpc_unencrypted=false |

The supported request types and the applicable service fee are taken from the CM account. The bot will not start-up when a message type is specified in the CM Account but not supported by the current version of the bot. Please make sure that the CM-Account and the running version of the bot are aligned with the supported versions of the services. The bot does always support the latest 3 versions of each service.
Creating a Wallet for the Bot
Navigate to Camino Wallet and create a wallet for use with your bot deployment. Once you have logged into your wallet, proceed to the "Manage Keys" tab. Here, click on "View Private Key" next to your key listed under the "My Keys" section.
Enter this private key into the configuration file for your bot.
Configuring for Development
To set up your environment for development, default example config files should be enough. Note that the default files have omitted certificate-related fields to allow for unencrypted communication.
Please ensure that the partner plugin host & port align with the active partner plugin settings. For further details, refer to the partner plugin page.
Ensure that your wallet, associated with the bot_key, contains CAM
tokens to cover transaction fees. Your C-Chain address will be displayed when
you run the bot.
Run
Run the bot with the command below, change the config file name file accordingly.
./bot -config camino-messenger-bot.yaml
Configuring the Docker Container
For those utilizing Docker for bot installation, load the configuration as shown below:
docker run -v ./cmb-config/:/cmb-config camino-messenger-bot --config /cmb-config/config.yaml
where: -v local_path:container_path - in this example the local directory ./cmb-config is mounted in the container into /cmb-config to be accessible from inside the container by the started process. camino-messenger-bot - the image name --config /cmb-config/config.yaml - parameters
For more detailed configuration, refer to the docker-compose.yaml file provided in the repository.
Example Output
After launching the bot, you can expect to see an output similar to the following (developer mode):
❯ docker run -v ./cmb-config/:/cmb-config camino-messenger-bot --config /cmb-config/config.yaml
