# Bridges

You can use bridge services to move assets from Ethereum to the GIWA Chain, or from the GIWA Chain back to Ethereum.

## Superbridge

Superbridge provides a native bridge that lets you transfer assets between Ethereum and the GIWA Chain. For more details, please refer to the [Superbridge documentation](https://superbridge.app/get#native).

{% hint style="info" %}
What is native bridge?

A **native bridge** is a bridge implemented using the systems and smart contracts provided directly by the GIWA Chain. It has low dependency on external services and benefits from protocol-level security guarantees.

However, because GIWA is a Layer 2, **withdrawal transactions are subject to a challenge period**. This means that withdrawing assets back to Ethereum typically involves **a waiting period of around 7 days**.
