ChainCatcher Message, Unichain has released a withdrawal guide for early developers to access bridging ETH. For users who deposited ETH through the unconfirmed Unichain bridge, the official documentation provides steps to withdraw ETH back to the mainnet. The withdrawal process is outlined as follows:

1. Initiate withdrawal on L2: Users can start the withdrawal either via an L1 deposit transaction or directly trading on L2.

2. Relay the withdrawal to L1: This step requires waiting for the proposer to suggest an output that includes the withdrawal on L1, generally updated once an hour.

3. Complete the withdrawal on L1: After relaying, users need to wait for a 7-day fault challenge period, then run a command to finalize the withdrawal.
