Coretime Kusama RPC & Node Infrastructure

Coretime Kusama is a parachain on the Kusama network that implements the Agile Coretime protocol. It manages the sale, ownership (as NFTs), and scheduling of coretime—the processing power allocated to parachains. This replaces the previous parachain auction system with a more flexible, on-demand blockspace market.

Why Use Coretime Kusama RPC?

Developers building on Coretime Kusama need reliable RPC access to:

Query coretime availability and pricing
Submit transactions to purchase or schedule coretime
Monitor coretime usage and ownership
Integrate with wallets, DeFi products, and analytics tools

OnFinality provides managed RPC endpoints and dedicated nodes for Coretime Kusama, so you can focus on your application without managing blockchain infrastructure.

Coretime Kusama RPC Endpoints

OnFinality offers both public and authenticated RPC endpoints for Coretime Kusama:

Public endpoint: Suitable for lightweight testing and simple experiments. Rate-limited and shared.
Authenticated endpoint: Provides clearer usage limits, request analytics, and a path to higher-capacity plans. Ideal for production workloads.

Both endpoints support HTTP and WebSocket transports using the Substrate JSON-RPC protocol.

Dedicated Nodes for Coretime Kusama

For teams that need full control and dedicated resources, OnFinality offers dedicated nodes:

Node types: Full, Archive, and Collator nodes
Lightning Restore: Sync a node from scratch in seconds using our proprietary technology
Global deployment: Nodes are available in Hong Kong (additional regions on request)
Full access: JSON-RPC, WebSockets, and metrics

Dedicated nodes are ideal for high-throughput applications, indexers, and services requiring consistent performance.

Archive & Trace Support

Coretime Kusama supports archive node access, allowing historical queries back to genesis. Trace capabilities are also available depending on the plan. Archive nodes are included at no extra cost with API service plans.
