Burn Refund

Once the user's previous transfer status is TRANSFER_TO_BE_REFUNDED, FE(front-end) needs to handle as follows to bring back user's assets to his/her wallet:

  1. Polling GetTransferStatus until transfer status is TRANSFER_TO_BE_CONFIRMED

  2. Submit on-chain mint request to cBridge PeggedTokenBridge contract with information provided by cBridge gateway in getTransferStatus response

  3. Once the refund transaction succeeds, the refund flow is complete.

If burn flow failed, it means the canonical tokens have been burnt. To bring them back, you should tell cBridge PeggedTokenBridge contract to mint corresponding tokens.

You should submit transaction to PeggedTokenBridgeV2 if you interact with PeggedTokenBridgeV2 for the previous transfer

Basically, it may take some time for gateway to prepare withdraw information. If the transfer status is stuck as TRANSFER_TO_BE_REFUNDED more than 30 minutes, you may contact our custom support
