# Collection

If a user sets multiple sub-addresses in their project and each address has assets, users with collection permissions can collect all sub-address assets to the specified wallet address, which is convenient for user management and use. The successfully collected funds and gas fees can be queried in the transaction records of the wallet.

## **Manual Collection**

1. Enter the API module and click "Sub-Address" - "Collect".
