# How to create Validator Keys?

### **Prerequisites**

**a.** A compatible wallet (currently only supports [**Metamask**](https://metamask.io/)) that holds more than 32 Eth

**b.** Generate `deposit_data-timestamp.json` which can be done through the [**deposit-cli tool**](https://github.com/ethereum/staking-deposit-cli/releases/). 

{% hint style="info" %}
Specifically, what we actually need is the `withdrawal_credentials` within the `deposit_data-timestamp.json`
{% endhint %}

### 1. Generating `deposit_data`/`withdrawal_credentials`

**Step 1:** Download the deposit CLI app [**here**](https://github.com/ethereum/staking-deposit-cli/releases/), ensuring you've selected the right one for your operating system.

{% hint style="warning" %}
Please make sure that you are downloading from the Ethereum Foundation's official GitHub account - <https://github.com/ethereum/staking-deposit-cli/releases/>

**Step 5:** Run the executable with the following command `deposit.exe new-mnemonic --num_validators 1 --chain mainnet` for Windows and `./deposit new-mnemonic --num_validators 1 --chain mainnet` for Linux or MacOS.
