# Bootstrapping Server-based Worker Node Accounts

Before you start using your Worker Node and be able to control blockchain set-up fully using Marketplace app, there is a set-of one-time actions that needs to be done as a prerequisite.

## Types of EWX Accounts

1. [Operator](https://docs-launchpad.energyweb.org/core-concepts/worker-node-operator) Account - an EWX account which serves as the main account of the operator to be used in EWT management (lifting/lowering), subscriptions, rewards, etc
2. Worker Node Account - an EWX account with the sole purpose of casting votes on behalf of the operator (interacting with blockchain).

## Prerequisites

1. Public Address of the Worker Node Account - the worker node account must already be created using any of [wallet which supports EWX](https://wiki.polkadot.network/docs/wallets-and-extensions).\* \
   \
   \****Disclaimer*** -> *If you use Launchpad Managed Worker Node offer, there is an option to automatically generate Worker Account along with Worker set-up.*<br>
2. Operator Account with enough EWT balance - create an account from [any wallet which supports EWX](https://wiki.polkadot.network/docs/wallets-and-extensions) and make sure to [lift](https://docs-launchpad.energyweb.org/core-concepts/energy-web-tokens/token-lifting) enough EWT for signing-up as operator, linking worker account to operator, [opting-in to solution groups](https://docs-launchpad.energyweb.org/core-concepts/subscription), etc

## Step by step guide to setup your worker node

Please be informed that below actions can be conducted using both:

1. Marketplace Desktop App - download the latest version from <https://www.energywebx.com/>
2. Marketplace Web App (**Recommended**) - [https://marketplace.energywebx.com/](https://marketplace.energywebx.com/#/discover)

### Sign-up as operator

To sign-up as an operator, you must prepare your "operator" EWX account. This account is just a normal account created on EWX network via any supported Polkadot wallet. For now, we suggest to use [Sub Wallet](https://www.subwallet.app/) or Nova Wallet. Make sure to always keep your seedphrase copied and secured elsewhere. In addition, please ensure that your operator account has sufficient EWT balance to proceed with any on-chain transaction.

Please follow below steps to sign-up as an operator.

1. Connect your operator account\
