Transfer
To accomplished user’s transfer, FE(front-end) needs to do the following things:
- Get basic transfer configs to get correct user’ input for assets transfer
- After collecting all needed information, always get updated estimation for the transfer.
- Check user’s on-chain token allowance for cBridge contract. If the allowance is not enough for user token transfer, trigger the corresponding on-chain approve flow
- Submit on-chain transfer request to cBridge contract on source chain
- Get transfer status repeatedly to check whether the transfer is complete.
