# eth\_accounts - Optimism

Example code for the eth\_accounts json-rpc method. Сomplete guide on how to use eth\_accounts json-rpc in GetBlock.io Web3 documentation.

This method is used to retrieve addresses that the node controls.

{% hint style="info" %}
In the context of GetBlock's infrastructure, since no private keys are stored on the nodes, this method will return an empty array. It's primarily useful for compatibility with tools that expect this endpoint to exist.
{% endhint %}

### Parameters

* None

### Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": []
}
```

### Response Parameters

* **`id`**: A unique request identifier, matching the `id` sent in the request body.
* **`jsonrpc`**: Specifies the use of JSON-RPC version 2.0.
* **`result`**: An empty array, as GetBlock nodes do not store private keys.

### Use Case

The eth\_accounts method is commonly used for:

* Web3 provider initialization
* Ethereum tool compatibility
* Client configuration checks

#### Error handling

<table><thead><tr><th>Status Code</th><th>Error Message</th><th>Cause</th></tr></thead><tbody><tr><td>403</td><td><pre><code>RBAC: access denied
</code></pre></td><td>Missing or invalid ACCESS_TOKEN.</td></tr></tbody></table>

#### Integration with Web3

The `eth_accounts` can help developers to:

* Identify available signing accounts
* Auto-select a default wallet in development
* Validate that a local signer exists
* Simplify onboarding in testing environments
