Coretime Polkadot RPC Endpoints & Dedicated Nodes | OnFinality

Coretime Polkadot is a system parachain on the Polkadot network that manages the allocation and scheduling of coretime — the computational resources that enable parachains to produce blocks. Launched as part of Polkadot's Agile Coretime framework, the Coretime Chain replaces the previous parachain auction model with a more flexible system where coretime can be purchased in bulk (28-day reserved blockspace) or on-demand (pay-per-block). Coretime is represented as NFTs, enabling secondary markets, splitting, and interlacing.

Developers building on Coretime Polkadot need reliable RPC endpoints to interact with the chain — querying coretime availability, submitting purchase transactions, or monitoring assignments. OnFinality provides managed RPC endpoints and dedicated node infrastructure for Coretime Polkadot, allowing teams to focus on their applications without operating their own nodes.

What is Coretime Polkadot?

Coretime Polkadot is the chain responsible for the sale, ownership, and scheduling of coretime on Polkadot. It enables parachains to secure blockspace through two mechanisms:

• Bulk Coretime: Purchase a core or portion of a core for a fixed 28-day period, represented as an NFT that can be split, shared, or resold.
• On-Demand Coretime: Pay per block for sporadic block production, ideal for variable workloads.

The Coretime Chain interacts with the relay chain and parachains via XCM, making it a critical component of the Polkadot ecosystem.

Why Use OnFinality for Coretime Polkadot RPC?

OnFinality offers authenticated RPC endpoints for Coretime Polkadot, providing:

• Advanced Features: Archive and trace support for historical data and debugging.
• Scalability: A path from shared API endpoints to dedicated nodes for higher throughput.
• Global Infrastructure: Nodes deployed in multiple regions for low-latency connections.

Whether you're building a wallet, DeFi product, analytics tool, or backend service, OnFinality's Coretime Polkadot RPC endpoints give you the reliability you need.

How to Connect to Coretime Polkadot

1. Create or sign in to your OnFinality account.
2. Select Coretime Polkadot from the supported networks list.
3. Create an API endpoint or deploy a dedicated node.
4. Test your connection using the example method chain_getBlock.
5. Monitor request usage, errors, and limits before moving critical traffic.

Coretime Polkadot uses the Substrate JSON-RPC protocol and supports both HTTP and WebSocket transports.

Public vs Private RPC

Public RPC endpoints are suitable for lightweight testing but often lack reliability for production workloads. OnFinality's private endpoints offer authenticated access, request analytics, and a clear scaling path — essential for team projects and high-volume applications.
