eth_estimateGas - TRON RPC Method
Estimate gas required for transactions on TRON. Essential for optimizing transaction costs for TRC-20 transfers, wallet operations, and EVM-compatible smart contract integrations.
Estimates the gas necessary to execute a transaction on TRON.
Why TRON? Build on the TVM-compatible Layer 1 for TRC-20 payments, wallet APIs, and low-cost smart contract execution with TVM compatibility paired with native TRON wallet APIs, DPoS block production, and low-cost transaction flows.
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 TRC-20 transfers, wallet operations, and EVM-compatible smart contract integrations
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.
