eth_estimateGas - opBNB RPC Method
Estimate gas required for transactions on opBNB. Essential for optimizing transaction costs for fully on-chain games, high-frequency DeFi, and cost-sensitive applications on BNB Chain.
Estimates the gas necessary to execute a transaction on opBNB.
Why opBNB? Build on Binance's high-performance L2 processing 100M+ daily transactions with the lowest L2 gas fees with sub-$0.0001 gas fees, 5-10K TPS, sub-second block times via Volta/Maxwell upgrades, and OP Stack architecture.
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 fully on-chain games, high-frequency DeFi, and cost-sensitive applications on BNB Chain
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32000 | Execution reverted | Transaction would fail |
| -32602 | Invalid params | Invalid transaction parameters |
