# Bridging

**Bridging** allows you to transfer supported Avant Protocol tokens (e.g., `avETH`) across supported blockchains directly in the app. Cross-chain transfers are routed in-app through **Chainlink CCIP and LayerZero**.

## Chain Availability

For a detailed breakdown of which Avant assets are native to each blockchain and which can be bridged, please see the overview table on our [Core Tokens](/overview/core-tokens.md) page.

This guide shows how to run a standalone bridge transfer in the Avant application. In many product flows, bridging is handled automatically in the same execution path.

#### Step-by-Step Guide

1. **Open the Bridge Interface**

Navigate to the [Avant application](https://app.avantprotocol.com/) and open the [Portfolio](https://app.avantprotocol.com/) page. Click the **Bridge** button next to the asset you want to bridge.

2. **Select the Source Chain**

From the dropdown menu, select the specific Avant token you wish to bridge according to its source chain (where the tokens are now).

> **Note**: The destination address will default to your connected wallet. You can edit this field if you wish to send the bridged tokens to a different address.

3. **Select the Amount and the Destination Chain**

* **Amount:** Input the quantity of the token you want to transfer.
* **Destination Chain:** Select the output token according to its destination chain (where you want to send your tokens to)

4. **Review Details & Bridge**

The interface will display the estimated bridging fee and the ETA (Estimated Time of Arrival). Review this information carefully before proceeding.

* **Approve:** Before initiating the bridge, you must grant the protocol permission to interact with the selected token.
* **Bridge:** After the approval is confirmed, click the **Bridge** button and confirm the final transaction in your wallet.

#### **Monitoring Your Transfer**

Once you have submitted the transaction, you can monitor its status in the bridge interface.

The transfer should typically complete within the ETA provided. However, times can vary depending on the congestion of the networks involved. If your transaction takes significantly longer than the estimated time, please reach out to the team.
