eth_estimateGas - Pulsechain RPC Method
Estimate gas required for transactions on Pulsechain. Essential for optimizing transaction costs for low-cost DeFi, staking protocols, and Ethereum-compatible dApps with reduced fees.
Estimates the gas necessary to execute a transaction on Pulsechain.
Why Pulsechain? Build on the Ethereum fork L1 with lower gas fees and proof-of-stake consensus with full Ethereum state fork, proof-of-stake consensus, lower gas fees than Ethereum mainnet, and PulseX DEX ecosystem.
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 low-cost DeFi, staking protocols, and Ethereum-compatible dApps with reduced fees
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.
