That's definitely not true. WeChat has a bunch of ecommerce stuff built in among other features. You can pay for stuff on WeChat and there are stores. It even has translation built in to facilitate buying and selling between people from different countries.

I think there are also apps and other stuff there too. It's more like a chat app that became an ecommerce and mini-app platform.

It's similar with KakaoTalk in Korea, which now also has a payment system in addition to acting as a regular bank, and allows you to buy various things including, say, hairdresser appointments. 93% smartphone market share.

Kakao has a separate app for everything. Quite different from WeChat. KakaoTalk, KakaoTaxi, KakaoPay etc etc

I wouldn't say that those are all extremely well integrated with each other.

Sorta both - the hairdresser booking and other commerce is in the main messenger app.

Also Line, which is also used in many parts of East Asia.

Facebook also has all of this, though I conceed that it doesn't have a built in user to user payments solution... Yet.
