Keep percentage of wallet transactions for site owner

I am using Terawallet to process tipouts to performers on a website that is for live video.

A client can tip to the performer, and the plugin I use for live video, Videowhisper, can be configured to set the percentage of the tipout that the performer gets.

However, this plugin doesn’t have a place where I configure where MY percentage of the tipout goes to.

So, let’s say that the performers keep 90% of tips, and I take 10%.

Someone tips $1, the performer gets $.90, I get $.10.

I cannot work out WHERE it is in Terawallet that I set it up so that the $.10 goes into MY SITE’S wallet, so that I get my share.

I also need this plugin to be configured to allow WITHDRAWALS via the Verotel payment gateway, as ACH and Paypal won’t work for what I’m doing.

HELP, PLEASE.
