Function introduction: This module mainly records the withdrawal information used by trading exchanges. Each withdrawal needs to be approved by the system before it can be officially transferred out of the chain. In order to facilitate operations, this module is equipped with a small amount of exemption function to automatic review.

Instructions:
- Each withdrawal can be withdrawn only after the administrator approves it. Audit logic: The withdrawal initiated by the user will first review the operation of the exchange's risk control system. If an abnormality is found, the system audit will fail and the dubious behaviors will be prompted, followed by the general backend administrator audit and merchant administrator review. If any party fails to approve, the withdrawal will be rejected. In order to facilitate the operation of merchants, a small exemption function has been added, a small amount of assets will be automatically reviewed.
- Query area: support to filter top-up data by currency, user information (ID, email or mobile phone), withdrawal address, TXID, and period of time.
- In the data list, clicking on the user ID will jump to the user details to view the detailed data; clicking on TXID or the withdrawal address will jump to the blockchain browser to query the on-chain processing details of the asset.
- Withdrawal records will be listed in reverse order of recharge time, giving priority to the data record of the most recently initiated withdrawal.
- The data in the list supports data export according to the filtering conditions.
Automatic review of small assets
The small asset automatic review is established when the user's account is normal. After the risk control system is approved, the withdrawal records that meet the small exemption conditions will be automatically approved. If the merchant wants to enable the small-amount exemption function, the administrator needs to bind Google authentication, and only the super administrator has the operation authority.
