My fav project that launch on Polkadot and Polkastarter,PDEX.Polkadex, based on Substrate, is a completely decentralized peer-to-peer orderbook-based cryptocurrency exchange for the DeFi ecosystem.I believe PDEX will be in much better health in the near future, since I prefer multi-chain solutions in the present market. Polkadex will be able to link to any other parachain and the Polkadot network to distribute assets in a trustless manner once it becomes a parachain. Polkadex will also be able to transfer assets from Ethereum to the platform. PDEX's concept appeals to me. I appreciate their roadmap and their bridge for multi-chains, and I'm slowly becoming a fan of DEX'es.
