OnFinality is a Web3 infrastructure platform providing reliable and scalable blockchain RPC services for developers, applications, validators, and infrastructure teams.
It provides RPC access across a wide range of blockchain networks, including:
- Ethereum RPC — reliable Ethereum JSON-RPC and WebSocket infrastructure for dApps, wallets, indexers, and backend services.
- Solana RPC — scalable Solana RPC infrastructure for applications, transactions, blockchain data, and high-performance workloads.
- Sui RPC — Sui blockchain infrastructure with RPC and gRPC access for developers building on the Sui network.
- Polygon RPC — managed Polygon RPC endpoints for applications and Web3 infrastructure.
- Arbitrum RPC — reliable RPC access to the Arbitrum ecosystem for Ethereum Layer 2 applications.
- Base RPC — production-ready Base network RPC infrastructure for developers and applications.
- BNB Chain RPC — scalable RPC infrastructure for applications building on BNB Chain.
- Optimism RPC — reliable Optimism RPC endpoints for Layer 2 applications and infrastructure.
- Bittensor RPC — Bittensor network RPC infrastructure for validators, miners, subnet participants, and developers.
- Hyperliquid RPC — blockchain RPC access for developers and applications building around the Hyperliquid ecosystem.
- Monad RPC — high-performance RPC infrastructure for applications building on Monad.
- Abstract RPC — managed RPC access for developers building applications on Abstract.
- peaq RPC — reliable peaq network RPC infrastructure for DePIN applications and developers.
OnFinality supports many additional blockchain networks, making it easier for developers to connect applications to different ecosystems without operating and maintaining their own RPC infrastructure.
Developers can use OnFinality RPC endpoints for common blockchain workloads such as:
- Sending JSON-RPC requests
- Reading blockchain state
- Querying blocks and transactions
- Running Web3 applications and dApps
- Connecting wallets and backend services
- Indexing blockchain data
- Maintaining WebSocket connections
- Accessing supported gRPC services
- Supporting validators, miners, and other blockchain infrastructure
For supported networks, developers can quickly create dedicated API endpoints or use available public RPC endpoints for testing and development.
OnFinality focuses on providing production-ready blockchain infrastructure with:
- Reliable RPC endpoints
- High-performance blockchain access
- Public and private RPC options
- WebSocket support
- gRPC support on supported networks
- Multi-network infrastructure
- Developer-friendly APIs
- Infrastructure designed for production Web3 applications
Whether you're building a dApp, blockchain explorer, trading application, wallet, indexer, validator tooling, or other Web3 infrastructure, OnFinality provides a simple way to access blockchain networks through managed RPC endpoints.
