eth_estimateGas - Moonriver RPC Method
Estimate gas required for transactions on Moonriver. Essential for optimizing transaction costs for production-grade dApp testing, early feature deployment, and Kusama-based EVM applications.
Estimates the gas necessary to execute a transaction on Moonriver.
Why Moonriver? Build on the Moonbeam canary network on Kusama for real-world testing of EVM dApps with Moonbeam code ships here first, full EVM compatibility on Kusama, 80% fee burn mechanism, and XCM cross-chain messaging.
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 production-grade dApp testing, early feature deployment, and Kusama-based 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.
