Implementing custom fees

Hi, I was wondering whether there is any known good way to implement custom fees.

In simple terms, I am developing a portal that allows others to trade using their Binance API keys. Is there any common way to implement custom fees? I would like to charge my users with extra fee for every transaction they do through my portal.

I would appreciate any help :slight_smile:

There is no official solution by Binance to reduce your commission from third-party trades. The third-party operator is expected to implement their own logic to handle their commissions.

Roger that, thanks :slight_smile:
I guess Binance Link is the closest thing to what I would need.
