Cross-sharding that is what make this project interesting to me and from what I've read before the cross-shard and cross-chain infrastructure will be by end of this year.. Also if you go to their website and scroll down all the way to Milestones and Roadmap you will see "Coinbase Rosetta Integration".. I am confident they are working on something with coinbase and will get listed there.. I also like Stephen Tse CEO's background..
