i will try to summarize what bitclave's vision is

What bitclave is trying to do is much more bigger than most of the investors think

matchico is one product on top of BASE ecosystem (bitclaves's main product) and you can earn/get CAT tokens for using it

desearch is another product on top of BASE where we will also get CAT

these 2 products are considered third party DAPPs just so happens Bitclave build them to test the BASE platform

then BASE gathers DATA of your activity on the Bitclave search engine and makes you offers through match.ico or other 3rd party DAPPs
