eth_estimateGas - Zetachain RPC Method

Estimates the gas necessary to execute a transaction on Zetachain.

Why Zetachain? Build on the universal omnichain blockchain enabling cross-chain smart contracts across 50+ chains including Bitcoin with native Bitcoin support, 50+ chain interoperability via UNISON, no bridging required, and partnerships with Curve and SushiSwap.

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 omnichain DeFi, native Bitcoin smart contracts, cross-chain asset management, and unified liquidity aggregation

Code Examples

curl -X POST https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_estimateGas",
    "params": [{
      "from": "0x5F0b1a82749cb4E2278EC87F8BF6B618dC71a8bf",

    }],

  }'

Error Handling

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