eth_estimateGas - Scroll RPC Method
Estimate gas required for transactions on Scroll. Essential for optimizing transaction costs for zero-migration DeFi protocols, zkEVM-native dApps, and 100+ ecosystem projects with native Ethereum tooling.
Estimates the gas necessary to execute a transaction on Scroll.
Why Scroll? Build on the largest zkEVM by market share with $750M+ TVL and bytecode-level Ethereum equivalence with bytecode-level EVM equivalence, native Hardhat/Remix/MetaMask support, decentralized proof validation, and Scroll SDK for L2/L3 deployment.
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 zero-migration DeFi protocols, zkEVM-native dApps, and 100+ ecosystem projects with native Ethereum tooling
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.
