eth_estimateGas - Cronos RPC Method

Estimates the gas necessary to execute a transaction on Cronos.

Why Cronos? Build on the EVM-compatible Crypto.com blockchain with fast finality and deep Crypto.com ecosystem integration.

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 DeFi protocols, NFT marketplaces, and Crypto.com ecosystem integrations

Code Examples

curl -X POST https://api-cronos-mainnet-archive.n.dwellir.com/YOUR_API_KEY \

    "jsonrpc": "2.0",
    "method": "eth_estimateGas",
    "params": [{
      "from": "0x5C7F8A570d578ED84E63fdFA7b1eE72dEae1AE23",

    }],

  }'

Error Handling

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