eth_estimateGas - Linea RPC Method
Estimate gas required for transactions on Linea. Essential for optimizing transaction costs for enterprise DeFi (Aave, Renzo), institutional cross-border payments via SWIFT pilots, and zkEVM-native applications.
Estimates the gas necessary to execute a transaction on Linea.
Why Linea? Build on Consensys-backed zkEVM L2 with $1B+ TVL and 807% growth in 2025 with 15-30x lower fees than Ethereum mainnet, 6,200 TPS throughput, SWIFT integration with 12+ institutions, and $725M Consensys backing.
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 DeFi (Aave, Renzo), institutional cross-border payments via SWIFT pilots, and zkEVM-native applications
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.
