eth_call - IoTeX RPC Method
Execute smart contract calls without creating transactions on IoTeX. Essential for reading contract state for decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data.
Executes a new message call immediately without creating a transaction on IoTeX. Used for reading smart contract state.
Why IoTeX? Build on the leading DePIN infrastructure blockchain powering 130+ applications in the $27B+ DePIN ecosystem with W3bstream offchain compute, Quicksilver AI data verification, Vodafone partnership for 5M+ cell tower integration, and ioID device identity.
Use Cases
The eth_call method is essential for:
- Reading contract state - Query view/pure functions
- Simulating transactions - Test execution without gas costs
- DeFi integrations - Check prices, balances, allowances for decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data
- Complex queries - Execute multi-step contract logic
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32000 | Execution reverted | Contract function reverted |
| -32602 | Invalid parameters | Invalid data encoding |
| -32015 | VM execution error | Contract logic error |
