Polkadot RPC Endpoints & Dedicated Nodes

Polkadot is a Layer 0 protocol that connects and secures a network of specialized blockchains called parachains. Developers build on Polkadot to create interoperable dApps, DeFi protocols, wallets, and analytics tools that can communicate across chains via Cross-Consensus Messaging (XCM).

To interact with Polkadot, applications need reliable access to the network through RPC endpoints or dedicated nodes. OnFinality provides managed Polkadot RPC APIs and dedicated node infrastructure for production workloads.

Why Use OnFinality for Polkadot RPC?

Managed API Endpoints – Get started quickly with authenticated HTTP and WebSocket endpoints. No need to run your own node.
Archive & Trace Support – Access full historical state and trace data for deep analytics and debugging.
Dedicated Nodes – Deploy a private Polkadot node for maximum performance, control, and custom configuration.
Global Regions – Endpoints available in Hong Kong and N. Virginia to reduce latency.
Observability – Monitor request usage, errors, and limits through the OnFinality dashboard.

Key Features

Protocol: Substrate JSON-RPC
Transport: HTTP and WebSocket
Advanced Access: Archive, trace, and dedicated nodes
Common Use Cases: Production dApps, wallets, DeFi products, analytics tools, games, bots, and backend services

How to Connect

Create or sign in to your OnFinality account.
Select Polkadot from the supported networks list.
Create an API endpoint or deploy a dedicated node.
Test the endpoint using chain_getBlock.
Monitor usage and move critical traffic to production.

When to Choose Dedicated Nodes

If your application requires consistent performance, custom runtime configurations, or high throughput, a dedicated Polkadot node gives you full control without sharing resources.

OnFinality makes it easy to scale from a shared API endpoint to a dedicated node as your project grows.
