Estimates the gas required to execute a transaction on the Ethereum network.

Example

import { getRpcClient, eth_estimateGas } from "thirdweb/rpc";
const rpcRequest = getRpcClient({ client, chain });
const gas = await eth_estimateGas(rpcRequest, {
 to: "0x...",
 ...
});
function eth_estimateGas(
  request: EIP1193RequestFn<
    [
      {
        Method: "web3_clientVersion";
        Parameters?: undefined;
        ReturnType: string;
      },
      {
        Method: "web3_sha3";
        Parameters: [data: `0x${string}`];
        ReturnType: string;
      },
