eth_estimateGas - Monad RPC Method
Estimate gas required for transactions on Monad. Essential for optimizing transaction costs for high-throughput DeFi, latency-sensitive trading, and scalable EVM applications.
Estimates the gas necessary to execute a transaction on Monad.
Why Monad? Build on the parallel EVM L1 delivering 10,000 TPS with 400ms blocks and sub-cent gas fees with optimistic parallel execution, MonadBFT consensus, $244M Paradigm-led funding, and consumer-grade validator hardware requirements.
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 high-throughput DeFi, latency-sensitive trading, and scalable EVM 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.
