# About Bridging

## What is a bridge?

A bridge is a smart contract which allows holders to move their crypto or digital assets from one network to another. 

In the case of Chiliz Chain, CHZ holders can move their tokens between Ethereum Mainnet and Chiliz Chain Mainnet. 

{% hint style="info" %}
On Ethereum Mainnet, CHZ tokens are ERC-20 tokens, \
while on Chiliz Chain, CHZ is the native token.
{% endhint %}

## Bridging your CHZ

There are several bridging dApps that allow you to bridge your CHZ to Chiliz Chain.

### Dcentralab's Chainport

The Chainport bridge can bridge ERC-20 CHZ tokens from Ethereum to wCHZ tokens (wrapped CHZ) on Chiliz Chain. It also very versatile, in that it can also work with several other tokens.

This means that once you have bridged an ERC-20 CHZ token from Ethereum to a wCHZ token on Chiliz Chain, you need to unwrap that wCHZ to obtain a proper CHZ token. 

To achieve that, follow this guide:

{% endcontent-ref %}

The resulting CHZ tokens are no different to regular CHZ tokens, it's just one more step to the bridging process.

### Chiliz Bridge

Our Chiliz Bridge is meant to bridge ERC-20 CHZ tokens from Ethereum directly to a native CHZ token on Chiliz Chain. It is less versatile that Chainport, but does the job in one step.
