eth_estimateGas - Polygon RPC Method
Estimate gas required for transactions on Polygon. Essential for optimizing transaction costs for enterprise solutions (Starbucks, Disney, Reddit), gaming, DeFi, and stablecoin payments.
Estimates the gas necessary to execute a transaction on Polygon.
Why Polygon? Build on the most adopted Ethereum scaling solution with 45,000+ dApps and enterprise partnerships with $4B+ TVL, sub-$0.01 transactions, 8M+ daily transactions, and zkEVM for enhanced security.
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 enterprise solutions (Starbucks, Disney, Reddit), gaming, DeFi, and stablecoin payments
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.
