eth_estimateGas - Moonbase RPC Method
Estimate gas required for transactions on Moonbase Alpha. Essential for optimizing transaction costs for EVM dApp testing, XCM integration validation, and pre-mainnet deployment verification.
Estimates the gas necessary to execute a transaction on Moonbase Alpha.
Why Moonbase? Build on the Moonbeam testnet for risk-free EVM dApp development and deployment testing with free testnet tokens, full EVM compatibility, XCM testing capabilities, and identical feature set to Moonbeam mainnet.
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 EVM dApp testing, XCM integration validation, and pre-mainnet deployment verification
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.
