Astar RPC Endpoints, API & Dedicated Nodes

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

• dApps: Reliable RPC for user interactions.
• Wallets: Fast transaction submission and balance queries.
• DeFi: Low-latency access for trading and liquidity.
• Analytics: Archive nodes for historical data.
• Bots and backends: Consistent uptime for automated services.

Astar RPC and developer resources

Astar RPC access is useful when a product needs dependable chain reads, transaction submission, and a clear path from a first request to production infrastructure.

Best fit: mainnet production workflows for parachain apps, collators, and Substrate backends.

What builders usually check first:

• Read blocks, storage, events, and governance or staking data from Substrate-based chains.
• Support wallets, indexers, parachain apps, collators, validators, and analytics services.
• Plan node infrastructure when the workload needs isolated resources or chain-specific operations.

Supported capability notes:

• Authenticated Astar RPC/API access for parachain apps, collators, and Substrate backends.
• HTTP and WebSocket support for app, backend, and integration workflows.
• Archive access for historical state, analytics, or compliance-style queries.
• Dedicated node options when shared RPC no longer fits traffic or isolation needs.

Decision notes:

• Environment: mainnet. Protocol family: Substrate JSON-RPC.
• HTTP and WebSocket support is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Dedicated node options are available when the workload needs isolated resources or more operational control.
• Available regions listed by the network spec include N.Virginia, Hong Kong.

A quick connection check usually starts with chain_getBlock, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Shared RPC is usually enough for early integration, prototypes, and moderate app traffic.
• Consider dedicated nodes when traffic becomes sustained, workloads are latency-sensitive, or isolation and monitoring become operational requirements.

• Create or manage RPC endpoints
• Review RPC pricing
• Explore dedicated nodes
