eth_estimateGas - TRON RPC Method

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

curl -X POST https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/jsonrpc \
  -H "Content-Type: application/json" \

Error Handling

Tip: If estimation fails, the transaction would likely revert if sent.
