Kadena command-line reference

The Kadena command-line interface (kadena) provides direct access to the Kadena blockchain and to commands that help you create, deploy, and manage applications for the Kadena network. You can use the Kadena command-line interface to perform tasks interactively or in scripts and automated workflows that don't allow interactive input.

The Kadena CLI has one primary entry point—the kadena parent command. By providing a single entry point for performing a wide range of tasks, the Kadena CLI integrates naturally into the typical development workflow. With commands designed specifically for building, testing, and managing Kadena-based applications, you can focus on building innovative applications using familiar tools.

What are the prerequisites? Node version? npm or pnpm version?

The Kadena CLI is packaged in a TypeScript library that you can install using a package manager such as npm or pnpm.

For example, run the following command to install globally using npm:

Run the following command to install globally using pnpm:

To verify the package is installed and display usage information, type kadena and press Return:

You can use the kadena parent command with different flags and subcommands to perform different types of operations.

The basic syntax for running kadena commands is:

Depending on the subcommand you select, the arguments, options, and flags you specify might apply to the parent command or to a specific subcommand. You can use the --help flag to display usage information for the kadena parent command, for a specified subcommand, or for a subcommand action. For example, to see all of the options available for adding a new wallet, you can run the following command:

The following diagram provides an overview of the kadena command-line interface:

Use the kadena parent as the primary entry point for commands used to create, test, deploy, and managed decentralized applications you develop for the Kadena network. Use the flags, subcommands, actions, and arguments to specify the operations you want to perform interactively or quiet mode.

The basic syntax for running kadena commands is:

You can use the following optional flags with the kadena parent command or with any of the kadena subcommands.

Subcommands to perform actions or organized into categories that describe the subject of the action you want to perform. For example, you can create and manage all wallet-related information using the wallet subcommand. Use the following subcommands to select the category of information for the operation you want to perform.

For reference information and examples, select an appropriate subcommand.

If you want to minimize the information you enter on the command-line, you can enter arguments by responding to interactive prompts. Responding to prompts interactively is typically the best approach when getting started, eliminating the need to look up or remember the argument required for the action you want to perform. As you gain experience, you can reduce interactive prompting by specifying the arguments as part of the command.

If you want to disable all interactive prompts and confirmation messages, you can use the --quiet flag. The --quiet flag enables you to automate tasks in environments where interactive input is impractical, such as continuous integration (CI) pipelines. If you include the --quiet flag in a command, the command suppresses all interactive prompts and skips confirmations, so that the command executes uninterrupted. This mode ensures that automated processes can run smoothly and efficiently, without the need for manual intervention.

The --legacy flag ensures that the output format for commands related to wallets, keys, and transactions aligns with earlier cryptographic standards and with existing workflows and tools, such as Chainweaver. This flag is especially useful if you need to interact with tools that rely on a legacy format for processing transactions or if you need to maintain backwards compatibility for a wallet or other application.
