hey @nall-near, we use this component to prompt Discovery users to accept terms of service. We've integrated this component into near.org in a way that it will be rendered whenever our terms of service are updated in IPFS, and when wallet connected users visit near.org who have not accept the current version of ToS.

Accepting the ToS issues a transaction to write into the index.tosAccept index on social DB with the current blockheight. You can see this in the socialDB Explorer if you input yourAccountName.near/** and scroll down to view tosAccept

@shelegdmitriy is a great person to connect with for more detail on how this component works, and how to leverage the existing component(s) in this proposed fast auth sign-up flow.
