Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

0.fromThe address the transaction is sent from.
0.toThe address the transaction is directed to.

0.gasPriceInteger of the gasPrice used for each paid gas.
0.valueInteger of the value sent with this transaction.
0.dataHash of the method signature and encoded parameters. For details see Ethereum Contract ABI.
