Approve bridge to assume custody of tokens one time #736

Closed tungnnt closed 2 years ago

In this step, I found that approve step approves a permission for the bridge to use a specific number of token in the wallet. When I deposit more than this specific number of token in to substrate, it fails to excute the transaction, and I need to approve again to have it worked again. Can I approve token for just one time ?

Hey! Technically you are able to approve for an insanely high amount one time and make deposits without any future approves. But this is highly not recommended as a basic security reason.
