# Supported Networks & Tokens

#### **List Networks**

[Swagger UI](https://swagger.blockz.fi/swagger/index.html)

Retrieve the list of blockchain networks supported by Blockz.

```http
GET /affiliate/v1/networks
```

**Response Example:**

```json
[
  {
    "id": 1,
    "name": "Ethereum",
    "type": "EVM",
    "supports_optimized_swap": false,
    "icon_url": "https://assets.hotpot.tech/icons/1/tokens/usdt.png",
    "supports_custom_tokens": false
  }
]
```

{% hint style="info" %}
**Note:** If `supports_custom_tokens` is set to `true` for a network, custom tokens can be used on that network. In this case, the tokens returned by the API represent commonly used tokens and do not constitute a complete list of all supported tokens.
