Moonriver (MOVR)
Key data
updated $0Moonriver (MOVR) is a companion network to Moonbeam, built on the Kusama blockchain — think of it as the faster-moving, experimental sibling where new features get tested first. Its ticker is MOVR, and the token is used to pay for transactions, staking, and governance on the network. In simple terms, it's a smart contract platform that's fully compatible with Ethereum, so developers can deploy their existing Ethereum apps with almost no changes.
Frequently asked questions
What is Moonriver and how is it different from Moonbeam?
Moonriver is the canary network of Moonbeam: a live testing environment on Kusama where new code ships before it lands on Moonbeam (which runs on Polkadot). Both networks are Ethereum-compatible smart contract platforms, but Moonriver moves faster and carries more risk, since updates arrive there first. MOVR is the native token of Moonriver, while GLMR serves Moonbeam.
How does Moonriver work technically?
Moonriver operates as a parachain on Kusama, meaning it leases a slot and shares Kusama's security rather than running its own validators. It uses a Nominated Proof-of-Stake (NPoS) consensus mechanism, where token holders nominate collators who produce blocks. Because it's EVM-compatible, developers can use familiar Ethereum tools like MetaMask, Solidity, and existing smart contracts directly.
How is MOVR emission and supply structured?
MOVR has a fixed maximum supply of 11.5 million tokens. New tokens are issued as rewards for collators and stakers, with an annual inflation rate that decreases over time — a portion of each block reward also goes to the on-chain treasury. There's no pre-mined allocation for the team; a large share of tokens was distributed through a crowdloan on Kusama.
How can you store and use MOVR?
MOVR can be stored in wallets that support Moonriver, including browser wallets like MetaMask (with the network added) and Polkadot-compatible wallets. Beyond holding, the token is used to pay gas fees for transactions and smart contracts, to stake with collators for rewards, and to vote on governance proposals that shape the network's future.
