Chain Config

Chain config is a JSON file that contains the private key, rpc endpoints, and network name you want to use. This file is used by the CLI to interact with the blockchain.

{
    "private_key": "<private_key>",
    "rpc_wasm": "<cosmwasm_rpc>",
    "rpc_evm": "<evm_rpc>",
    "network": "<network>"
}

Defaultly, the CLI will always looking for chain-config.json file in the current directory. If the file does not exist, you will need to create one.

$ lighthouse init chain-config

If you want to use a different file name or path, you can specify it using the --config or -cf flag.

$ lighthouse --config /path/to/your/config.json <command>
