Sonic RPC Endpoints on OnFinality
OnFinality provides managed Sonic RPC endpoints for developers building on Sonic, a high-performance EVM Layer-1 blockchain. With sub-second finality and over 10,000 transactions per second, Sonic is designed for the next generation of decentralized applications. OnFinality's Sonic RPC API gives you reliable access to the network without the overhead of running your own node.
What is Sonic?
Sonic is an EVM-compatible Layer-1 blockchain that combines a novel consensus design with strong incentives and production-grade infrastructure. It offers:
- High throughput: Over 10,000 TPS
- Sub-second finality: Fast transaction confirmation
- EVM compatibility: Deploy existing Solidity contracts with minimal changes
- Secure Ethereum gateway: Access to Ethereum liquidity and assets
Why Use OnFinality for Sonic RPC?
Running a Sonic node requires significant hardware and maintenance effort. OnFinality's managed RPC endpoints let you focus on building your dApp while we handle infrastructure. Benefits include:
- Reliable uptime: Production-grade infrastructure with monitoring
- Scalability: Endpoints that grow with your traffic
- Observability: Request analytics and usage metrics
- Archive and trace support: Access historical state and transaction traces
Sonic RPC Endpoint Details
- Network: Sonic Mainnet
- Chain ID: 146 (0x92)
- Protocol: EVM JSON-RPC
- Transports: HTTP and WebSocket
- Advanced access: Archive and trace methods available
How to Connect
- Create or sign in to your OnFinality account.
- Select Sonic from the supported networks list.
- Create an API endpoint.
- Test with
eth_blockNumber.
- Monitor usage and move to production.
Use Cases
Sonic RPC endpoints from OnFinality are suitable for:
- DeFi applications: High-frequency trading, lending, and yield farming
- Wallets: Transaction submission and balance queries
- Analytics tools: Historical data retrieval via archive nodes
- Games and NFTs: Real-time state updates
- Backend services: Reliable blockchain connectivity
Comparison with Public RPC
Public Sonic RPC endpoints are often rate-limited and shared among many users, making them unsuitable for production workloads. OnFinality provides authenticated endpoints with clearer limits, request analytics, and a path to higher capacity.
Sonic RPC and developer resources
A useful Sonic RPC page should make the connection path, supported capabilities, and production planning trade-offs clear before a developer opens the dashboard.
Best fit: mainnet production workflows for wallet flows, contract apps, and live backends.
What builders usually check first:
- Read current chain state for apps, dashboards, wallets, and backend services.
- Submit transactions and monitor confirmations from Ethereum-compatible tools.
- Query logs, receipts, and historical state when indexers or analytics pipelines need more than the latest block.
- Debug contract behaviour with trace data where the network supports it.
Supported capability notes:
- Authenticated Sonic RPC/API access for wallet flows, contract apps, and live backends.
- Flexible HTTP and WebSocket access for app, backend, and integration workflows.
- Archive-capable workflows when the product needs older chain state.
- Trace-ready workflows for teams that need to inspect execution paths.
Decision notes:
- Environment: mainnet. Protocol family: EVM JSON-RPC.
- Flexible HTTP and WebSocket access is listed for supported app and backend workflows.
- Archive support is available for historical state or older chain-data queries.
- Trace support is available for transaction debugging and execution analysis.
A quick connection check usually starts with eth_blockNumber, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.
Planning the next step:
- Shared RPC is a practical starting point for integration, prototypes, dashboards, and many app backends.
- If your product becomes traffic-heavy or operationally sensitive, review the available upgrade path before relying on a single access pattern.
