CLI Sub-commands

Conflux CLI sub-commands is a collection of command line interfaces which allows you to interact with a local or remote Conflux node.

Manage Accounts​

account sub-command allows you to manage accounts at local machine.

new​

Create a new account at local machine.

Usage​

$ ./conflux account new --help
Create a new account (and its associated key) for the given --chain (default conflux).

USAGE:
    conflux account new [OPTIONS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --keys-iterations <NUM>    Specify the number of iterations to use when deriving key from the password (bigger is more secure). [default: 10240]
        --password <FILE>          Provide a file containing a password for unlocking an account. Leading and trailing whitespace is trimmed.

Example​

./conflux account new

list​

List all accounts at local machine.

Usage​

$ ./conflux account list --help
List existing accounts of the given --chain (default conflux).

USAGE:
    conflux account list

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

Example​

./conflux account list

import​

Import accounts from JSON UTC keystore files.

Usage​

$ ./conflux account import --help
Import accounts from JSON UTC keystore files to the specified --chain (default conflux)

USAGE:
    conflux account import --import-path <PATH>...

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --import-path <PATH>...    A list of file paths to import.

Example​

./conflux account import --import-path ./keystores

Public APIs​

Public API allows you to interact with a local or remote Conflux node via HTTP connection in JSON-RPC protocol. All public APIs are under rpc sub-command, and access to the JSON-RPC API at local machine with default url option.

OPTIONS:
        --url <url>    URL of RPC server [default: http://localhost:12539]

To access JSON-RPC API of remote Conflux node, please specify the correct --url option (e.g. http://10.1.5.6:12537). By default, JSON-RPC is enabled only for local access for security consideration. You can manually enable remote access by configuring jsonrpc_http_port in default.toml file.

# jsonrpc_tcp_port=12536
jsonrpc_http_port=12537
# jsonrpc_local_tcp_port=12538
jsonrpc_local_http_port=12539

All available commands are as following:

Send signed transaction​

Send a signed transaction which encoded in HEX format. Generally, this API is used for Java-Script API to send encoded transaction. To send a transaction with CLI, suggest to use private API send transaction.

Private APIs​

Private API allows you to interact with local Conflux node only via HTTP connection in JSON-RPC protocol. Private APIs are provided for user to manage the local Conflux node, and requires the jsonrpc_local_http_port configured in default.toml configuration file.

In addition, private APIs also helps developers to debug, test, and monitor the runtime of Conflux node.

All private APIs are under local sub-command, and access to the JSON-RPC API at local machine with default url option.
