Core Configuration

INX-Indexer uses a JSON standard format as a config file. If you are unsure about JSON syntax, you can find more information in the official JSON specs.

You can change the path of the config file by using the -c or --config argument while executing inx-indexer executable.

For example:

inx-indexer -c config_defaults.json

You can always get the most up-to-date description of the config parameters by running:

inx-indexer -h --full
