eth_estimateGas - Zetachain RPC Method
Estimate gas required for transactions on Zetachain. Essential for optimizing transaction costs for omnichain DeFi, native Bitcoin smart contracts, cross-chain asset management, and unified liquidity aggregation.
Estimates the gas necessary to execute a transaction on Zetachain.
Why Zetachain? Build on the universal omnichain blockchain enabling cross-chain smart contracts across 50+ chains including Bitcoin with native Bitcoin support, 50+ chain interoperability via UNISON, no bridging required, and partnerships with Curve and SushiSwap.
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 omnichain DeFi, native Bitcoin smart contracts, cross-chain asset management, and unified liquidity aggregation
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.
