# (Orbitchain.io) Bridge assets from BSC > Polygon
First, head up to the main page of the [orbitchain bridge](https://bridge.orbitchain.io/) (). You will see a pop up message about the fees, read them clearly before proceeding. **For bridging $AUTO from Binance Smart Chain to the Polygon Chain no extra fees are included**. The bridging of assets on orbitchain is divided in 3 parts:
### Part 1: Select a Coin to convert
1\) Click the "Select Coin" button in the top right:
2\) Scroll down in the token list until you see: AUTO - Binance Smart Chain, select the token and click "OK":
3\) You will see the available validators for the bridging transaction, for now for now there is only one group (BSC), click "OK" to proceed:
### Part 2: Select Chains and Connect a Wallet
4\) In the FROM CHAIN section, click the "SELECT CHAIN" dropdown and select BSC:
5\) Now it's time to connect your wallet with the orbitchain bridge. For now the only option is Metamask, select it and click "OK":
6\) You have to confirm the connection in your Metamask and this screen will pop up if the connection is succesfully made:
### **Part 3: Input Amount and Recipient Address**
7\) Now, key in the amount of $AUTO you want to transfer, and if it's your first time bridging $AUTO with orbitchain bridge, you have to approve the spending of $AUTO by clicking the "Approve" button:
8\) Now, select POLYGON in the "SELECT CHAIN" dropdown in the TO CHAIN section:
9\) After selecting the chain it's time to fill in the recipient address:
{% hint style="info" %}
Please check the recipient address carefully! Coins accidentally sent to another or a wrong address will be lost forever!
{% endhint %}
10\) After you've double checked the recipient address, click the "CONVERT NOW" button to start the bridging transaction:
11\) You will see a confirmation screen with the bridging details. Click the "Confirm" button to confirm the bridging transaction:
12\) After confirming, a new pop up appears with the transaction hash of the briding transaction. This step can take a while in case of network congestion on either side of the bridge:
{% hint style="info" %}
Even though the image shows "Transfer Complete!", please look at the "Waiting for the transaction to complete"
{% endhint %}
13\) When the bridging transaction is done, the following message with green text will be shown:
