Raydius aims at providing the most efficient and user-friendly platform for cross-chain applications. Raydius is a middleware solution designed to create a more connected blockchain ecosystem. Currently, building cross-chain applications is troublesome with various layer 1 and layer 2 protocols each supporting different development frameworks. Raydius solves the problem by offering the cross layer support as a service for developers so that they could focus on creating the product most needed by users. Raydius offers an EVM compatible layer 2 PoS side chain built on Substrate and it connects to different layer 1 and layer 2 blockchains through bi-directional bridges. There are also cross-chain bridge aggregators to allow users to have a one-stop experience using dApps on different chains.
