Moonriver operates as an Ethereum-compatible smart-contract parachain functioning on Kusama. Positioned as a companion network to Moonbeam, Moonriver serves as a continuously incentivized canary network. New code undergoes initial deployment and testing on Moonriver, where it can be scrutinized and validated under genuine economic conditions. Upon successful verification, the same code is then deployed to Moonbeam on Polkadot. Moonriver facilitates this process by offering a comprehensive EVM implementation, a Web3-compatible API, and bridges that establish connections between Moonriver and existing Ethereum networks. Consequently, developers can seamlessly deploy their Solidity smart contracts and DApp frontends to Moonriver with minimal adjustments.
