Using the Prysm Web Interface

This section outlines the step-by-step process for how to use Prysm with its built-in web interface.


Step 1: Get Prysm and join Ethreum mainnet or testnet#

To begin, follow the instructions to run Prysm in mainnet or testnet:

By the end of the documentation, you should have a functioning beacon node and validator client running!

Step 2: Restart your validator client with --web#

To launch the web interface, you will need to restart your validator client from step 1 with the --web flag. This will allow you to access the web interface by default on http://localhost:7500 if running on the same computer as your validator client and using, prysm.bat or building from source. For more advanced configurations, keep reading below in step (3).

If it is the first time you have ran your Prysm validator and have not yet created a wallet, you will be faced with a wallet creation screen allowing you to import the keystores generated from the Ethereum deposit-cli.


If you have already created a wallet, you will instead be faced with a signup page where you must set a password for your web interface.


The password for the web interface

For security reasons, the password for the Prysm web interface is different from your wallet password. We wouldn't want you typing your precious wallet password every time you login via a browser!

After you signup, you'll be able to access your dashboard and login any future times to the web interface.

Step 3: Configuration and common issues#

The web UI runs by default on port 7500 of the validator client if you are running with the --web flag. To customize this port, change the following flag to your liking:

--grpc-gateway-port (default: 7500 for validator)

The available parameters to customize are:

--grpc-gateway-hostThe host for the validator client's JSON-HTTP API, default
--grpc-gateway-portThe port for the validator client's JSON-HTTP API, default 7500

Step 4: Accessing the web interface from a remote computer#

If you are running your beacon node and validator on some server that you want to access from the outside, we recommend SSH local port forwarding to access it. For example, you would do the following from your home computer:

ssh -L 7500: user@host_ip

where you replace user@host_ip with the user and host ip address of the remote machine you are trying to access. This will forward all requests from your home computer's localhost:7500 to the remote instance's localhost:7500, allowing you to visit http://localhost:7500 from your favorite browser and then access the validator web interface! This is the safest approach to access it, as you are exposing the web interface to the open Internet.

Step 4: Monitor your beacon node and validator client logs, accounts, and more#

You can visualize your beacon node and validator client logs from the web interface easily by navigating to System Process -> Logs on the left-hand sidebar.

  • We recommend going through the "imported wallet" route, and importing your keys you obtained during the Ethereumlaunchpad deposit-cli process, as this is the most secure setup. Upon completing wallet creation, you will be redirected to your main dashboard, where you can see several important items such as your recent validating performance or your beacon node's sync status.

This page is useful to monitor how your processes are doing without needing to navigate to your terminal! In addition, you can visit your Wallet and Accounts -> Accounts page to view all your validating keys in an ordered table, explore their historical performance on, and import new ones.

Step 5: Contributing to the web interface code#

The web interface is open source and located at It is an Angular application, and we always welcome your help!

Web UI in development mode uses mock data by default

The recommended way to run prysm web is from the validator client itself via the --web flag. If you are building the web UI from source and doing npm start, you will be using fake, mock data! Keep that in mind if you are trying to use real accounts with the web UI.
