);About Moonriver
Connect your dApp, bot, or protocol to Moonriver Mainnet with BoltRPC. Teams deploying cross-chain protocols through the Polkadot ecosystem need reliable RPC on both Moonriver and Moonbeam, and BoltRPC supports both from a single provider.

Moonriver is Moonbeam’s canary network, running on Kusama (Polkadot’s canary network). Unlike a testnet, Moonriver is a live production network with real MOVR tokens and real economic value. New protocol features and upgrades are deployed to Moonriver before being promoted to Moonbeam. DeFi protocols that want to operate in the Moonbeam ecosystem typically launch on Moonriver first to validate their implementation in a real-value environment before the higher-stakes Moonbeam deployment. Moonriver provides Ethereum tooling compatibility within the Kusama ecosystem for protocols willing to operate at the experimental frontier of the Polkadot ecosystem.
Why BoltRPC
Teams deploying on Moonriver before promoting to Moonbeam need consistent RPC across both environments. BoltRPC supports Moonbeam and Moonriver from one provider with one API key. Switching from Moonriver to Moonbeam for production requires changing one environment variable. The endpoint format is identical.
Moonriver is Moonbeam's canary network on Kusama. Features and upgrades land on Moonriver before Moonbeam. Unlike testnets, Moonriver runs with real MOVR tokens and real economic value. DeFi protocols deployed here need reliable RPC just like mainnet deployments.
Moonriver gives Ethereum developers access to the Kusama parachain ecosystem via XCM. For protocols building cross-chain applications across Kusama and Ethereum, Moonriver is a key infrastructure layer that needs stable RPC.
Any Ethereum code works on Moonriver with a single endpoint change. The EVM interface is identical to Moonbeam.
Running a canary deployment alongside a production deployment typically means running two parallel RPC integrations. Predictable request-unit pricing means your Moonriver usage does not add meaningfully to your total costs relative to your Moonbeam usage.
