eth_estimateGas - Moonbeam RPC Method
Estimate gas required for transactions on Moonbeam. Essential for optimizing transaction costs for cross-chain DeFi, multi-chain dApps, and Ethereum-to-Polkadot bridging via XCM, Axelar, LayerZero, and Wormhole.
Estimates the gas necessary to execute a transaction on Moonbeam.
Why Moonbeam? Build on the cross-chain connected EVM platform on Polkadot with $65M+ TVL and 100+ projects with full EVM compatibility on Polkadot, native XCM cross-chain messaging, 10K+ TPS, 24% staking APR, and $0.015 transaction costs.
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 cross-chain DeFi, multi-chain dApps, and Ethereum-to-Polkadot bridging via XCM, Axelar, LayerZero, and Wormhole
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.
