Astar RPC Endpoints & Dedicated Nodes | OnFinality

Connect to Astar Network using OnFinality's managed RPC endpoints and dedicated node infrastructure. Astar is the leading smart contract hub on Polkadot, supporting both WASM and EVM environments. Whether you are building a dApp, wallet, DeFi protocol, or analytics tool, OnFinality provides reliable access to the Astar blockchain without the overhead of running your own node.

What is Astar Network?

Astar Network is the #1 smart contract platform for multichain on Polkadot. It supports multiple virtual machines (WASM and EVM) and connects the Polkadot ecosystem to Ethereum, Cosmos, and other major blockchains. With its Build2Earn program, Astar incentivizes developers to build and maintain dApps. Since winning its parachain auction in January 2022, Astar has become the top parachain by Total Value Locked (TVL).

Why Use OnFinality for Astar RPC?

OnFinality offers both public and private RPC endpoints for Astar. Public endpoints are suitable for testing and light usage, while authenticated endpoints provide higher rate limits, request analytics, and a clear path to dedicated infrastructure. For production dApps, dedicated nodes offer dedicated resources, archive access, and full control over node configuration.

Key Features

• Substrate JSON-RPC protocol with HTTP and WebSocket transport
• Archive node support for historical data queries
• Dedicated nodes for high-throughput workloads
• Global regions: Hong Kong and N. Virginia
• Request analytics to monitor usage and errors

Public vs Private Astar RPC

Public endpoints are free but shared among many users, leading to rate limits and variable performance. OnFinality's authenticated endpoints give you dedicated throughput, observability, and the ability to scale to a dedicated node when your project grows.

How to Connect to Astar with OnFinality

1. Create an OnFinality account.
2. Select Astar from the supported networks.
3. Create an API endpoint or deploy a dedicated node.
4. Test the endpoint using chain_getBlock.
5. Monitor usage and errors before moving to production.

Use Cases
