# (Orbitchain.io) Bridge assets from BSC > Polygon

First, head up to the main page of the [orbitchain bridge](https://bridge.orbitchain.io/) (<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:
