What is Moonriver?
Moonriver is an Ethereum-compatible, smart-contract parachain on Kusama. It is intended to be a companion network to Moonbeam, where it will provide a permanently incentivized canary network. New code will ship to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code will ship to Moonbeam on Polkadot.
It does this by providing a full EVM implementation, a Web3-compatible API, and bridges that connect Moonriver to existing Ethereum networks.
This allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonriver with minimal changes.
