 ## Usage and Benefits
 
-Allows dApps to quote users without the users every giving direct access to any part of their wallet, then handoff the quoted payload to compatible wallets to build, review, sign and broadcast.
+Allows dApps to output QR codes in a common format that compatible wallets can recognize and use to build and broadcast transactions.

+Allows dApps and wallets to follow one common pattern rather than unique and individual integrations.
