Learn how to use the Ethernal CLI

The CLI serves two purposes:

  • Synchronizing blocks & transactions with your dashboard

  • Synchronizing contract's artifact data for Truffle projects

Artifact data for Hardhat projects are synchronized with a plugin


Install the CLI globally with the following command:

npm install -g ethernal

Logging In

If you haven't done so already, this is the first thing to do after installing. Your email is stored in ~/.config/configstore/ Your password is stored in your local keychain. You only need to login once. If you need to log in with another account, you can just run the command again.

ethernal login

You can also skip the login command and use env variables: ETHERNAL_PASSWORD=yourpwd ethernal listen

Listening to transactions

To listen to transactions, the CLI will pull the server address of the latest used workspace. If you want to specify a different workspace you can use the -w flag.

ethernal listen

Or for a different workspace:

ethernal listen -w staging

If the passed workspace name is not found, it will default to the latest used.

When starting the CLI, it will automatically synchronize all blocks & transactions that are missing (if some happened when the CLI wasn't running for example).

Watching contracts artifacts (Truffle projects only)

If you are using Hardhat, head to this section.

The CLI will also watch by default your artifacts if you have run it in a Truffle project (there needs to be a truffle-config.js file in the directory).

If you are looking to set up a Truffle project:

Truffle Project Setup

If your chain is not running locally and you don't want to listen to transactions, but only synchronize artifacts, you can run

ethernal listen -l

And if you are on a remote server hosting the chain, and you don't want to watch for contracts, you can run:

ethernal listen -s

By default, only the name and the ABI of the contract are going to be uploaded. If you want to use the "Storage" tab of contracts page, you'll need to have the AST uploaded as well. To do so, pass the --astUpload flag as a parameter (this will upload the ast field, as well as the source field).

ethernal listen --astUpload








Specify the workspace to connect to

Latest used / First Created



Specify the directory to watch for artifact change. You can pass multiple parameters by using a comma as a separator.

. (current directory)



Do not watch for artifact change - only listen for transactions




Upload AST to decode storage




Do not listen for transactions - only watch for contract changes


Resetting a workspace

This will delete all accounts/blocks/transactions/contracts from a specific workspace

ethernal reset [workspace]
