The dapp section contains a list of dapps that exist within the Tezos network. In the upper part of the screen  we present promoted (whitelisted) dapps. You can also check TVL (total value locked) within Tezos protocols both in xtz and $ equivalent 
Scroll down to access the full list of existing dapps  or use the search field  to quickly skip to the dapp you're looking for.
Each dapp entry  also has relevant hashtags attached to it for your ease of searching and TVL figures for your reference. Clicking an entry will take you straight to the dapp's site.
