Coretime Polkadot RPC Endpoint and API

Parity

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.

Additional Info

Build faster with Coretime Polkadot RPC endpoints

Use OnFinality's Coretime Polkadot RPC APIs to connect wallets, dApps, dashboards, bots, and backend services without operating your own node from day one.

Public endpoint testing

Start with the Coretime Polkadot public RPC endpoint for lightweight checks, prototypes, and quick integration tests.

Authenticated API access

Move production traffic to authenticated endpoints when you need clearer limits, analytics, and operational visibility.

Standard RPC methods

Query Coretime Polkadot blocks, transactions, balances, events, and chain state through HTTP and WebSocket workflows.

Operate Coretime Polkadot infrastructure with more control

Production teams need more than an endpoint URL. They need observability, predictable capacity, and a path from shared RPC access to isolated infrastructure.

Request visibility

Track usage patterns and response activity so your team can understand traffic growth before it becomes an incident.

Dedicated node path

Use dedicated Coretime Polkadot nodes when your workload needs isolated resources, custom operations, or stronger capacity planning.

Archive and historical data

Plan for archive access when analytics, audits, indexers, or advanced app features need older Coretime Polkadot state.

Choose the right Coretime Polkadot RPC setup

Different Coretime Polkadot products need different infrastructure. OnFinality gives teams a practical path from public RPC testing to production-grade API and node operations.
