Raydius is a middleware platform that aims to connect the blockchain ecosystem. Building cross-chain applications can be difficult due to the different layer 1 and 2 protocols that support different development frameworks. Raydius addresses this problem by providing cross-layer support for developers, so they can concentrate on creating the products that users need. Raydius provides an EVM compatible layer 2-POS side chain on Substrate. It connects to different layer 1 or layer 2 blockchains via bi-directional bridges. Cross-chain bridge aggregators are available to provide a single-stop solution for users who want to use dApps from different chains. Raydius bridge aggregator connects to popular asset bridges such as multichain.xyz and Matic to provide the best routing possible for users who want to switch assets between blockchains.
