The callback settings page allows the following configuration operations:

1. Batch edit callback addresses
2. Set the default BTC address format
3. Set the minimum callback amount for currencies

## 1. Batch edit callback addresses

After clicking "Edit," a window will pop up on the right side. Here, you can enter the callback URL and then click confirm.

## 3. Set the minimum callback amount for currencies

Find the currency you wish to set under the minimum callback amount. Only currencies that have been added to the wallet will be displayed here. After selecting, click edit to bring up a numeric input box. Users can set a value below which a callback will not be triggered to prevent deposit harassment or dust attacks.
