With the Hop USDC bridge upgraded to utilize Circle's CCTP and the deprecation of the USDC.e bonder, transfers involving USDC.e now require manual withdrawal processing.
Hop allows you to withdraw hUSDC.e from the pool and transfer it to L1 at a 1:1 ratio. However, transferring hUSDC.e to L1 requires completing the full exit process, which takes at least 7 days after the root commit before the withdrawal can be finalized. To proceed, follow these steps:
Step 1: Initiate the bridge to L1
Go to the Convert page UI, select origin chain and ensure the convert method is set to "via Hop Bridge".
Initiate the transfer by clicking the "Convert" button.
Step 2: Submit "Commit transfers" transaction
Visit the Relay page UI and paste the transaction hash of your transfer on the origin chain into the Transfer ID field.
This will initiate the "Commit Transfers" transaction.
Step 3: Submit "Prove Withdrawal" transaction
On the same Relay page UI page, initiate the "Prove Withdrawal" transaction on L1 by clicking the "Relay" button again.
Alternatively, use superchainrelayer.xyz for OP stack chains to complete this step. Paste the transaction hash of the "Commit Transfers" transaction from Step 2 and click "Prove Tx".
This will initiate a 7-day exit period.
Step 4: Submit "Finalize Withdrawal" transaction
Visit the Relay page UI and paste the transaction hash of your transfer on the origin chain into the Transfer ID field.
This action initiates the "Finalize Withdrawal" transaction.
Alternatively, use superchainrelayer.xyz for OP stack chains to complete this step. Paste the transaction hash of the "Commit Transfers" transaction from Step 2 and click "Finalize Tx".
Step 5: Withdraw your transfer
Go to the Withdraw page UI and paste the transaction hash of your transfer on the origin chain into the Transfer ID field.
Click the "Withdraw" button and confirm the transaction processed the withdrawal transfer to your wallet.
