# List asset networks

> List the deposit and withdrawal networks available for an asset.

List the deposit and withdrawal networks available for an asset.

> [!NOTE]
>
> Use a Broker API Key. This endpoint reads Broker configuration and does not require X-User-Wallet-Address. See [Broker API Key and signing](https://dexbuilder.mintlify.site/en/api-reference/common/broker-authentication.md).

## Usage notes

* The response lists the available network configuration for the asset. `network` identifies the network; `vm` identifies EVM or Solana. Check the response for current availability.
* `min_deposit` and `min_withdraw` use display token units. `min_withdraw` may be omitted when no minimum is configured. Pass the required `x-perp-device-type` header; see [Platform API authentication](https://dexbuilder.mintlify.site/en/api-reference/dexbuilder/authentication.md).
