Crust RPC Endpoint and API

Crust

Crust Network is a decentralized storage blockchain protocol that incentivizes storage orders and utilization of IPFS storage nodes. It is one of the largest decentralized storage systems, enabling easy hosting of websites, dApps, NFTs, and personal files. Developers building on Crust need reliable RPC endpoints to interact with the network—reading blockchain data, submitting transactions, and integrating storage functionality into their applications.

Additional Info

Build faster with Crust RPC endpoints

Use OnFinality's Crust 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 Crust 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 Crust blocks, transactions, balances, events, and chain state through HTTP and WebSocket workflows.

Operate Crust 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 Crust 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 Crust state.

Choose the right Crust RPC setup

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