Returns an estimate of how much gas will be needed for the transaction to complete. When estimating gas, the transaction will not be automatically added to the network. This cannot be used as a hard indicator, as fluctuations on gas prices can occur very quickly, making estimates inaccurate after just a few seconds.

Request PayloadTransaction Call Object{from} - Address from which the transaction is sent.

* Optional

{to} - Address to which the transaction will be directed. {gas} - Integer of gas provided for transaction.

* Optional

{gas_price} - Integer of the gas price used for each paid gas.

* Optional

{value} - Integer of the value sent with this transaction.

*Optional

{data} - Hash of the method signature and encoded parameters.

* Optional

Result Fields{gas_used} - The amount of gas estimated to be necessary for the transaction to complete.

{gasLimit} - Maximum gas allowed in this block.

{timestamp} - The unix timestamp for when the block was collated. {txns} - Array of transaction objetcs.

{uncles} - Array of uncle hashes.

Submits a pre-signed transaction for broadcast to the network.

Result Fields{txnHash} - Transaction hash, or zero if the the hash isn't available yet.

Returns the transaction receipt of a specific transaction hash. Note that this isn't available for any transactions that hasn't been confirmed yet.

Request Payload{txnHash} - Transaction hash.

Result Fields{txnReceipt} - Transaction receipt object, or null when no receipt was found.

{txnHash} - Hash of the transaction.

{txnIndex} - Integer of the transactions index position in the block. {blockHash} - Hash of the block where the transaction was placed. {blockNumber} - Number of the block where the transaction was placed.

{from} - Address of the sender.

{to} - Address of the receiver.

{cumulativeGasUsed} - Total amount of gas used by the block.

{gasUsed} - Amount of gas used by the specific transaction.
