Moonriver is a fully Ethereum-compatible environment on Kusama. It is a highly specialized Layer 1.5 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonriver platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations.
Moonriver launched as a parachain on the Kusama network and is a companion network to Moonbeam. Moonriver provides a permanently incentivized canary network to which new code is shipped first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot.
