# Operator Account

Prepare your machine to install the tBTC v2 client

The client requires an Ethereum Key File of an Operator Account to connect to the Ethereum chain. This account is created in a subsequent step using Geth (GoEthereum).

The Ethereum Key File is expected to be encrypted with a password. The password has to be provided in a prompt after the client starts or configured as a `KEEP_ETHEREUM_PASSWORD` environment variable.

The Operator Account has to maintain a positive Ether balance at all times. We strongly advise you monitor the account and top-up when its balance gets below 0.5 Ether.

### Install Geth (GoEthereum)

To create a new Ethereum account, [install Geth](https://geth.ethereum.org/docs/getting-started/installing-geth) (GoEthereum) and create a new account using the command below. This account will subsequently be referred to as the Operator Account.

<pre class="language-bash"><code class="lang-bash"><strong>geth account new --keystore /home/$USER/.operator-key
</strong></code></pre>

When prompted, provide a password to protect the operator key file.&#x20;

{% hint style="info" %}
Use a password manager to generate a strong password and store it safely. It will be needed again during setup.
{% endhint %}

{% hint style="warning" %}
Avoid passwords that contain the following characters: ', ", \`, $\
These characters may be interpreted as part of the configuration which can lead to undesirable outcomes that may be extremely time intensive to correct.
{% endhint %}

Once the process completes, your public key will be displayed. Take note of your Operator Account public key.

{% hint style="danger" %}
DO NOT LOSE THE PASSWORD TO THE OPERATOR ACCOUNT.
{% endhint %}

### Funding your Operator Account

Your Operator Account will need to maintain a positive ETH balance at all times to ensure proper operation and availability of your tBTC v2 node.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.threshold.network/tbtc-signer-nodes/tbtc-v2-node-setup/operator-account.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
