Moonriver, a companion network to Moonbeam, provides a permanently incentivized network of canaries. Moonriver is the first port of call for new codes. This allows them to be tested and verified under real economic conditions. Once it is proven, the same code can be shipped to Moonbeam on Polkadot. You can quickly deploy your existing or new Solidity DApps to Moonriver parachain with minimal or no modifications. This will allow you to gain easy access the Kusama network. Moonriver mirrors Ethereum's Web3 RPC and accounts, keys, subscriptions and logs. This reduces the amount of changes required to run existing Solidity smart contract on the network. Easy replication of Ethereum's DApp can be done by Ethereum projects. Moonbeam can then deploy it using Hardhat, Truffle and Remix, as well as other popular deployment tools.
