Big update to the dapp dropped just now! We've added support for Decent.Land's Ark Protocol! You can read more about Ark here: ark.decent.land/#faq
tl;dr you can link your arweave identity with your cross chain identities! (just EVM right now, but NEAR, SOL, DESO, TEZ in the works!)
To link your EVM identity just head over to your profile, click edit, click identity, choose network, connect with metamask or brave wallet and hit link!
