eth_estimateGas - zkSync RPC Method
Estimate gas required for transactions on zkSync Era. Essential for optimizing transaction costs for RWA tokenization ($1.9B, 25% market share), hyperchain deployment via ZK Stack, and cross-chain DeFi.
Estimates the gas necessary to execute a transaction on zkSync Era.
Why zkSync? Build on Matter Labs' flagship zkEVM powering the Elastic Network of interoperable hyperchains with ZK Stack modular framework, hyperchain interoperability, native account abstraction, and $1.9B in tokenized real-world assets.
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 RWA tokenization ($1.9B, 25% market share), hyperchain deployment via ZK Stack, and cross-chain DeFi
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.
