The Flit token project is an Ethereum based project that came with a use case of providing a decentralized wallet service. I first got to see this project through an airdrop early last year but never got understand what its use case was as at then. After doing some of my tentative research about this project, I have come to understand that it was meant to provide a wallet service for its users yet this wallet is not available and its website too doesn't seem to perform anymore.
I can't really say for sure but it seems the project has shifted to another project name called flits and also the wallet is available for that one. The Flit token is still very well traded on Sistemkoin exchange but the spread is very high yet it still has a good 24 hour trading volume.
