I am not sure what you mean by multivendor.
Several extensions support multiple shops/donations/events which can all be served by the Stripe Plugin.
If your requirement is however to have multiple beneficiaries for the payments, based on the logic of the other component, this is not part of the functionality of our Stripe Payment Plugin.
We developed the Stripe Connect plugin to serve that purpose in Quick2Cart, and it was also working fine with JGive a couple of years ago. Development and sales were stopped because of the support cost (it was priced 300 Eur and still it wasn't convenient for us to sell it, so we pulled it from the market).
Now we are working on a new version to support the new architecture of the Joomla Common API based on TJ-Vendor, our plugin is still in testing and I guess the new TJ-Vendor should be released in the first quarter of 2018.
Please let me know which component you are using so I can provide you with more information.
btw update your Joomla! to 3.8.2
