WhenHub Interface is part of the WhenHub Interface Network, an ecosystem that uses blockchain-based smart contracts to create innovative ways in which independent workers and customers can connect for business transactions. WIN seamlessly addresses discovery, availability, trust, interaction and payment.

Using Interface, people seeking Subject Matter Experts (SMEs) can find them, interact with them, and finally pay for the SME’s time, without friction and with the convenience of a mobile application using digital utility tokens called "WHEN Tokens."

WHEN Tokens are automatically added to a user's wallet in the app when they sign-in. Tokens earned by Experts can be withdrawn to any third-party wallet that is ERC-20 compatible.

Amazing app idea. Needs a few fixes.

Alan the ExMormon Persuader

I am currently testing this app, and I I love it so far, however, have found a few issues.

It kicks me out when i am looking for an expert, and it does not let me click on the be an expert option.

I am using an iPhone X.

Got to talk with Scott Adams today!


What a time to be alive! Got to talk with Scott Adams while having my morning coffee, through an app on my phone, that uses Ethereum smart contracts to make it all happen. Call quality was great and I can this becoming a huge success. Thanks for making this happen, Scott!

Being an expert only available with linkedin login.


Why not AOL? Or Compuserve? Who uses LinkedIn any more? The fact that being an expert requires you to sign up for and waste time on another data-leaking social network speaks volumes about the quality of experts this app is attracting.
