This Command Line Interface allows users to interact with the Celo Protocol smart contracts.

Introduction

Getting Started

Optional

  • Run a Celo node full node. Commands will connect to a Celo node to execute most functionality. You can either use Forno (this is the easiest way) or run your own full node if you prefer. See the Running a Full Node instructions for more details on running a full node.

NPM Package

The Celo CLI is published as a node module on NPM. Assuming you have npm and git both installed, you can install the Celo CLI using the following command:

npm install -g @celo/celocli

{% hint style="info" %} We are currently deploying the CLI with only Node.js v12.x. If you are running a different version of Node.js, consider using NVM to manage your node versions. e.g. with: nvm install 12 && nvm use 12 {% endhint %}

{% hint style="info" %} If you have trouble installing globally (i.e. with the -g flag), try installing to a local directory instead with npm install @celo/celocli and run with npx celocli. {% endhint %}

Overview

The tool is broken down into modules and commands with the following pattern:

celocli <module>:<command> <...args> <...flags?>

The celocli tool assumes that users are running a node which they have access to signing transactions on, or have another mechanism for signing transactions (such as a Ledger wallet or supplying the private key as an argument to the command). See the documentation on the config module for information about how to set which node commands are sent to.

{% hint style="info" %} All balances of CELO or Celo Dollars are expressed in units of 10^-18 {% endhint %}

Using a Ledger Wallet

The Celo CLI supports using a Ledger hardware wallet to sign transactions.

Plugins

Additional plugins can be installed which make the CLI experience smoother. Currently, celocli only supports installing plugins published on NPM within the @celo/* and @clabs/* scopes.

{% hint style="danger" %} Installing a 3rd party plugin can be dangerous! Please always be sure that you trust the plugin provider. {% endhint %}

The autocomplete plugin adds an interactive autocomplete for bash and zsh shells. To enable the autocomplete plugin, follow the instructions provided at:

celocli autocomplete

The update warning plugin notifies the user if they are using an oudated version of the CLI. This plugin is enabled by default.
