Description Usage Arguments Details Value See Also Examples

eth_estimateGas returns an estimate of how much gas is necessary to allow the transaction to complete.

1	eth_estimateGas(to, data)

`to`	Address - Address the call is send to.
`data`	Data - Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI https://solidity.readthedocs.io/en/develop/abi-spec.html.

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.

Integer - Amount of gas estimated.
