IoTex RPC Endpoints & API Access | OnFinality

IoTex RPC Endpoints

IoTex is a purpose-built Layer 1 blockchain designed to connect smart devices to smart contracts, powering the DePIN (Decentralized Physical Infrastructure Networks) ecosystem. As an EVM-compatible chain, IoTex enables developers to build and deploy decentralized applications that interact with real-world IoT devices and data.

What Developers Use IoTex RPC For

IoTex RPC endpoints allow applications to read blockchain data, submit transactions, and interact with smart contracts on the IoTex network. Common use cases include:

• DePIN dApps: Manage device registries, verify off-chain data, and coordinate physical infrastructure.
• Wallets: Check balances, send IOTX tokens, and interact with DeFi protocols.
• Analytics & Indexing: Query historical data for dashboards, explorers, and data pipelines.
• Backend Services: Automate contract interactions, monitor events, and power bots.

IoTex RPC on OnFinality

OnFinality provides managed IoTex RPC API endpoints with the following capabilities:

• Protocol: EVM JSON-RPC (compatible with Ethereum tooling)
• Transport: HTTP and WebSocket
• Advanced Access: Archive node support for historical data queries
• Network: Mainnet (Chain ID: 4689)

Developers can use OnFinality's IoTex RPC endpoints for production workloads without running their own node infrastructure. The service includes request analytics, usage visibility, and a clear scaling path from shared APIs to higher-capacity plans.

Key Considerations for IoTex RPC

When choosing an IoTex RPC provider, consider:

• Archive vs Full Node: Archive nodes store the complete historical state, essential for applications that need past data (e.g., analytics, compliance). OnFinality supports archive access for IoTex.
• Rate Limits: Public endpoints may have restrictive rate limits. Authenticated endpoints provide clearer limits and higher throughput.
• Latency & Reliability: OnFinality's infrastructure is designed for consistent performance, though actual latency depends on geographic region and network conditions.

Getting Started with IoTex RPC on OnFinality

1. Create or sign in to your OnFinality account.
2. Select IoTex from the supported networks list.
3. Create an API endpoint (shared or dedicated, if supported).
4. Test the endpoint using eth_blockNumber or your preferred method.
5. Monitor usage, errors, and limits before moving critical traffic.
