Moonriver RPC Endpoint and API

Moonbeam

Moonriver is a companion network to Moonbeam and serves as an incentivized canary network on Kusama. It provides a full Ethereum-like environment, supporting Solidity smart contracts and EVM-compatible tools. New code ships to Moonriver first, where it can be tested under real economic conditions before being deployed to Moonbeam on Polkadot.

Additional Info

Build faster with Moonriver RPC endpoints

Use OnFinality's Moonriver RPC APIs to connect wallets, dApps, dashboards, bots, and backend services without operating your own node from day one.

Public endpoint testing

Start with the Moonriver public RPC endpoint for lightweight checks, prototypes, and quick integration tests.

Authenticated API access

Move production traffic to authenticated endpoints when you need clearer limits, analytics, and operational visibility.

Standard RPC methods

Query Moonriver blocks, transactions, balances, events, and chain state through HTTP and WebSocket workflows.

Operate Moonriver infrastructure with more control

Production teams need more than an endpoint URL. They need observability, predictable capacity, and a path from shared RPC access to isolated infrastructure.

Request visibility

Track usage patterns and response activity so your team can understand traffic growth before it becomes an incident.

Dedicated node path

Use dedicated Moonriver nodes when your workload needs isolated resources, custom operations, or stronger capacity planning.

Archive and historical data

Plan for archive access when analytics, audits, indexers, or advanced app features need older Moonriver state.

Choose the right Moonriver RPC setup

Different Moonriver products need different infrastructure. OnFinality gives teams a practical path from public RPC testing to production-grade API and node operations.
