# DERP Token Bridge

This bridge function now supports DERP tokens, which are **our DerpDEX native tokens (DERP)**. This allows users to bridge across four chains:

1. Ethereum
2. ZkSync Era
3. opBNB
4. Base

### How to bridge?&#x20;

1. Firstly, go to <https://app.derpdex.com/#/derp-bridge>. Connect to the network you want to bridge from. Then, choose which token and network chain you wish to bridge to.&#x20;

4. It will display the pending claim transactions after they are completed. Your token will be sent to the bridge contract, and is now being verified by the blockchain.&#x20;

5. Once the transaction is verified, the **Claim** button will appear. It will switch to the target network and allow the user to claim the bridging token.&#x20;

{% hint style="info" %}
Make sure you have enough native tokens (E.g. ETH or BNB) on the destination chains to pay the gas fees for claiming your bridged tokens.&#x20;
{% endhint %}
