No, but:
https://democracy.earth uses a couple of systems to connect to it (
https://fortmatic.com,https://www.portis.io,
https://walletconnect.org) - I don't know why they ditched
https://metamask.io.
Overall the adoption of these systems is too difficult. Something that could be overcome with signal/mobilecoin.
Democracy earth is just an example application. Overall I would appreciate to own my data and have it secure (like signal provides), when it comes to the whole ecosystem of the future for: social media, voting, contracts, etc.
