# eth\_getCode - Somnia

This method returns the bytecode at a given address on the Somnia network. This is useful for verifying contract deployment, checking if an address is a contract, and analyzing contract bytecode. Somnia's compiled EVM executes this bytecode at near-native speeds.

## Parameters

| Parameter   | Type   | Required | Description                                             |
| ----------- | ------ | -------- | ------------------------------------------------------- |
| address     | string | Yes      | The address to get code from                            |
| blockNumber | string | Yes      | Block number in hex, or "latest", "earliest", "pending" |

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.getblock.io/api-reference/somnia/eth_getcode-somnia.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
