About Moonriver

Moonriver is an Ethereum-compatible smart contract parachain on the Kusama network. It serves as a canary network before deployment to Polkadot, allowing developers to build and deploy Ethereum-compatible applications on a subnet of Kusama. Moonriver aims to provide a fully functioning, Ethereum-compatible environment for developers looking to build decentralized applications (dApps) and DeFi products.

Moonriver’s Origin and Purpose

Moonriver was created by PureStake and Moonbeam in collaboration with Kusama. It integrates the Moonbeam platform, which allows Ethereum developers to build on Substrate, into Kusama as a parachain. The goal is to provide a sister network to Moonbeam on Polkadot that can test new code under real economic conditions first.

As a canary network, Moonriver provides valuable information to teams preparing to launch Moonbeam on Polkadot. It essentially replicates the environment of Moonbeam, allowing developers to build and deploy Solidity-based smart contracts for DeFi, NFTs, and more on Kusama with low risk and cost.

Moonriver’s Technology and Infrastructure

Moonriver uses the Moonbeam platform to enable compatibility between Substrate and the Ethereum Virtual Machine (EVM). This allows decentralized applications from Ethereum to be deployed on Moonriver with minimal changes. Developers can utilize familiar Ethereum development tools like Truffle, Remix, and MetaMask.

Moonriver also implements cross-chain integrations between Kusama, Moonbeam on Polkadot, and external chains. For example, XCM allows trustless bridges between Moonriver to transfer tokens and data. Statemint, an account-based sister parachain, will bring token transfers to Bitcoin and even non-blockchain based payment networks in the future.

Moonbeam and Polkadot Integration

As mentioned, Moonriver closely integrates with Moonbeam and serves as its canary network on Kusama. Code is deployed and tested on Moonriver first before making its way onto Moonbeam on Polkadot. This allows developers to de-risk their launch on a live environment.

Moonbeam will connect Polkadot to Ethereum and other external networks. Developers can take advantage of Polkadot’s interoperability, security, scalability while still using familiar Ethereum developer tools. So Moonriver provides an environment for testing Web3 applications before reaching the wider Polkadot ecosystem.

Moonriver Tokenomics

The Moonriver token (MOVR) serves multiple purposes including governance, paying transaction fees, and providing collateral for certain DeFi applications.

MOVR has a max supply of 10 million tokens. 30% of the initial supply was allocated to Moonbeam token holders via a token claims process. Additional token distribution comes from liquidity mining incentives, decentralized storage provider Filecoin, the Moonriver Foundation, and the Moonbeam Foundation.

There was no public sale of MOVR tokens. However, they can be earned via staking, liquidity provision, and participating in the governance process. The value of MOVR comes from its utility within Moonriver and speculated future usage as adoption grows.

Moonriver Governance Mechanism

Moonriver utilizes on-chain governance allowing MOVR holders to direct upgrades, parameters changes, or even runtime logic alterations. This gives the community power over future development decisions.

Any MOVR holder can create and submit proposals by staking a deposit. After creation, there is a mandatory referendum period before it moves to a public vote. All stakers and collators who bond MOVR can then vote on active proposals.

If a proposal passes with sufficient votes, then it will be enacted automatically by the chain. Rejected proposals lose their deposit. This governance mechanism ensures updates align with community interests.

Moonriver Ecosystem Growth

Since its launch in mid-2021, Moonriver has seen rapid growth in development activity and projects:

  • Over 56 million transactions processed
  • 3000+ smart contracts deployed
  • 500+ active accounts daily
  • Integrations with major Ethereum infrastructure like The Graph, Chainlink, and more
  • Multiple DeFi, NFT, and other dApps launched including Solarbeam, Bit.Country, RedPanda Earth, and more

This demonstrates strong ecosystem adoption. As Moonbeam prepares for Polkadot integration, further growth is expected on Moonriver as it continues serving as a development testbed.

Key Moonriver DApps and Projects

Here are some of the key decentralized applications being built on Moonriver currently:

  • Solarbeam – A decentralized exchange modeled after UniSwap and SushiSwap on Ethereum. It offers seamless trading between cryptocurrency assets.
  • Bit.Country – A metaverse world builder enabling users to buy, develop, and monetize virtual land NFTs.
  • RedPanda Earth – An NFT collection centered around programmatically generated pixel art red pandas.
  • StellaSwap – A decentralized exchange providing automated liquidity pools using an AMM model.
  • Basilisk – An end-to-end decentralized exchange supporting cross-chain swaps via XCM.

These are just a sample of the many exciting projects leveraging Moonriver to build on Kusama using Ethereum-compatible infrastructure.

Moonriver Roadmap and Future Development

Moonriver development runs in parallel with Moonbeam. Upcoming milestones include EVM Object Format (EOF) support which provides full compatibility with Ethereum’s accounts and blance model. Additionally, token bridging and cross-chain integrations will continue expanding.

The Moonriver community also has an active governance process for determining feature upgrades. These proposals have recently funded efforts like deploying Chainlink price feeds and integrating The Graph for easier dApp data indexing.

In the future, Moonriver’s functionality will mirror Moonbeam’s roadmap. This includes integrated bridges to major blockchains, oraclizing, integration with institutional grade KYC partners, and more.

Investment Potential and Risks

As Moonriver expands in functionality and adoption, MOVR has significant speculative investment upside. However, investors should be aware of risks like technical issues from unproven code to the fundamental volatility and complexity of the crypto market.

Additionally, some speculative value of MOVR relies on Moonbeam successfully launching and integrating into Polkadot. Any delays with Moonbeam could negatively impact perceptions and pricing of MOVR as well.

While risky, early adopting investors into leading Polkadot parachains like Moonriver could see substantial returns if adoption continues growing at its current pace. However, there are many variables that could positive or negatively impact holding the MOVR token.


In summary, Moonriver serves as the canary network before Moonbeam integrates into Polkadot. Its technology stack enables Ethereum-compatible smart contracts, dApps, NFTs, DeFi platforms, and more to be built on Kusama.

The project has seen tremendous ecosystem growth in a short period while providing valuable testing for Moonbeam’s upcoming Polkadot launch. MOVR has speculative investment value aligned with further adoption of Moonriver and Moonbeam. While risks exist, the project shows promise for expanding Polkadot’s functionality.


Moonriver is an Ethereum-compatible smart contract platform that aims to provide interoperability between Ethereum and Kusama. It allows developers to deploy Ethereum-based applications and assets to Kusama with minimal code changes. Moonriver leverages Kusama’s robust infrastructure to provide a scalable environment for projects.

Moonriver was created by PureStake, a blockchain infrastructure company, in collaboration with Moonbeam. PureStake saw the need for an Ethereum-compatible parachain on Kusama and developed Moonriver to meet that need.

Moonriver works by leveraging Moonbeam’s technology to connect the Ethereum and Kusama ecosystems. Projects can deploy Solidity smart contracts and DApps to Moonriver, allowing them to tap into Kusama’s speed and low transaction costs. Moonriver uses bridge infrastructure to enable asset transfers between the two chains.

Moonriver provides a sandbox environment for testing Ethereum-based applications before deploying them on Polkadot. Developers can experiment with Solidity contracts, optimizations, and integrations. It also offers a portal for projects to access Kusama’s community and expand their reach.

MOVR, Moonriver’s native token, can be purchased on centralized exchanges such as, MEXC, and KuCoin. It’s also available on decentralized exchanges like Uniswap. Make sure to do thorough research before choosing an exchange or platform.

Non-custodial wallets like IronWallet allow direct control of assets while avoiding third-party risks. IronWallet supports MOVR and provides an easy way to store Moonriver tokens securely. Always exercise caution when choosing a cryptocurrency wallet.

Moonriver differentiates itself by providing an on-ramp for Ethereum projects to enter the Polkadot ecosystem quickly. Instead of rebuilding from scratch, existing Ethereum dApps can deploy easily to Moonriver via established tooling. This saves development time and resources.

While MOVR cannot be mined, users can participate in Moonriver’s consensus process as collators. Collators run nodes and add new blocks to the chain. It requires staking MOVR and meeting minimum hardware requirements. More details can be found in the Moonriver documentation.
