eth_estimateGas - Arbitrum RPC Method
Estimate gas required for transactions on Arbitrum. Essential for optimizing transaction costs for high-volume DeFi (GMX, Uniswap, Aave), gaming, and cross-chain applications.
Estimates the gas necessary to execute a transaction on Arbitrum.
Why Arbitrum? Build on Ethereum's leading Layer 2 with 46% L2 market share and $12B+ TVL with full EVM compatibility, 1.5M daily transactions, and $3B+ DAO treasury for ecosystem growth.
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-volume DeFi (GMX, Uniswap, Aave), gaming, and cross-chain 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.
