# Cross chain swap

## **Guide to using the O3swap bridge for asset transfers between BSC and HECO**

**Let's look at the example of BNB (BSC) to HUSD (HECO) asset transfer step-by-step**

1. Go to https://o3swap.com/swap. Make sure that Binance Smart Chain is selected in MetaMask. Click Connect Wallet in the upper right corner. Then select the BSC logo and click Connect MetaMask.

3\. In the second line, you need to do the same thing, but select the HECO network. In addition you can get an HT token to pay GAS fees on the HECO network. But sometimes the HT token is not available.
