What is Moonriver

Moonriver is a smart-contract blockchain on Kusama that strives to provide compatibility with the existing Ethereum developer toolchain and network.


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 Moonriver 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.

MOVR Staking Rewards 

Collator & Delegator

1. Staking Rewards
Collators are rewarded at the end of every round (300 blocks) for their work from 2 rounds ago.

The distribution of the 5% annual inflation goes as follows:

  • 1% goes to incentivizing collators (for collators)

  • 1.5% goes to the parachain bond reserve

  • The remaining 2.5% will go to users that stake their tokens ( for delegators)

Out of that 2.5%, collators gets the rewards corresponding to their stake in the network.The rest are distributed among nominators by stake.

2. Useful Information

  • Minimum nomination amount — 5 MOVR

  • Round duration — 300 blocks, time per round is approximately 1 hour

  • Max eligible nominators per collator — for a given round, only the top 100 nominators by staked amount are eligible for staking rewards

  • Max collators per nominator — a nominator can nominated 25 different collators

  • Bonding duration — nomination takes effect in the next round (funds are withdrawn immediately)

  • Unbonding duration — 2 rounds

  • Reward payout time — 2 rounds. Rewards are distributed automatically to the free balance

  • Collator commission — fixed at 20% of the annual inflation (5%). Not related to the nominators reward pool

  • Nominators reward pool — 50% of the annual inflation
