Westend RPC Endpoints & Dedicated Nodes

Westend is Polkadot's official testnet, providing a sandbox environment for developers to test parachains, validators, and dApps before deploying on Polkadot or Kusama. Unlike mainnets, Westend uses free test tokens (WND), eliminating financial risk during development.

Why Use Westend RPC?

Developers rely on Westend RPC endpoints to:

Test smart contracts and runtime upgrades
Validate parachain onboarding flows
Simulate staking and governance scenarios
Integrate wallets and backend services
Perform QA and staging releases

Westend RPC on OnFinality

OnFinality provides managed Westend RPC endpoints with HTTP and WebSocket transport. Our infrastructure supports:

Archive nodes for full historical data access
Trace APIs for debugging and analysis
Dedicated nodes for isolated, high-throughput workloads

Endpoints are available in Hong Kong region. Create an API key in your OnFinality dashboard to get started.

Public vs. Private Westend RPC

Public endpoints are suitable for lightweight testing. For team projects and production staging, authenticated OnFinality endpoints offer clearer rate limits, request analytics, and a scaling path to dedicated infrastructure.
