Transfer Assets Across Chains

Let’s say, you want to transfer 11 BUSD from BNB Chain to Flow. The steps are made simple in cBridge:

  1. Select "BNB Chain" in the dropbox next to "From" and "Flow" in the dropbox next to "To".

  1. You will be prompted to switch your wallet to BNB Chain if it's not already connected. Enter the amount you want to send under "Send". You should see the estimated amount you will receive under "Receive (estimated)".

Note that there will be a difference between the amount you send and the amount you receive, which is determined by the Bridge Rate and fees. For the exact definition of each item in the transaction, check the tooltips next to each of the terms.

  1. Note that If you transfer BUSD to Flow for the first time, you will be prompted to “Create BUSD vault in your Follow wallet” first.

  1. Then click “Approve” on Flow Reference Wallet.

  1. Then click “Approve BUSD”, and you will be prompted to confirm on Metamask.
