let userNonce = await tx.getUserNonce(userAddress);

###Send ETH to other person

gasPrice : gas price for transaction

from : address of sender

to : address of receiver

valueSend : amount of Ethereum in transaction (wei format)

privateKey : private key of sender

let hash = await tx.sendEth(gasPrice, from, to, valueSend, privateKey )

###Send Transaction in order to create contract address from an address

gasLimit : gas limit of this transaction

from : address of sender

newContractData : data of deploy new contract

valueSend : set 0 because we don't need to send ETH to any addresses

privateKey : private key of sender

let txHash = await tx.sendTransactionWithoutTo(gasPrice, gasLimit, from, newContractData, valueSend, privateKey);

###Check status of transaction hash
