eth_estimateGas - IoTeX RPC Method
Estimate gas required for transactions on IoTeX. Essential for optimizing transaction costs for decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data.
Estimates the gas necessary to execute a transaction on IoTeX.
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_estimateGas method is essential for:
- Transaction preparation - Set appropriate gas limits
- Cost estimation - Calculate transaction costs before sending
- Error detection - Identify reverts before spending gas
- DeFi operations - Estimate costs for decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32000 | Execution reverted | Transaction would fail |
| -32602 | Invalid params | Invalid transaction parameters |
Tip: If estimation fails, the transaction would likely revert if sent.
