Altair RPC Endpoint, API Service & Dedicated Nodes | OnFinality

Altair is the experimental, boundary-pushing little brother to Centrifuge. It is a Substrate-based parachain on Polkadot that enables users to tokenize and finance assets ranging from art NFTs to undiscovered assets. Developers building on Altair need reliable RPC endpoints and node infrastructure to interact with the chain, read state, submit transactions, and run production services.

Altair RPC Endpoints

OnFinality provides managed Altair RPC endpoints over HTTP and WebSocket. These endpoints are suitable for dApps, wallets, DeFi products, analytics tools, games, bots, and backend services. The public endpoint is rate-limited and intended for testing; for production use, sign up for an API key to get higher rate limits, request analytics, and dedicated support.

Example endpoint:

• HTTPS: https://altair.api.onfinality.io/public
• WebSocket: wss://altair.api.onfinality.io/public-ws

Key features:

• Archive and trace support for historical queries and deep analysis.
• Regions: N.Virginia.
• Compatible with Substrate JSON-RPC.

Dedicated Nodes

For teams that need full control, OnFinality offers one-click deployment of dedicated Altair nodes. Choose from full, archive, or collator node types. Deploy in a globally distributed, multi-cloud environment with metrics and monitoring. Use Lightning Restore to sync nodes in seconds instead of days.
