Transaction Fee
Gas refers to the transaction fee that will be charged to any transaction or execution on the Smart Contract in KardiaChain network. Gas is measured in HYDRO.
1KAI = 10^18 HYDRO
1 OXY = 10^9 HYDRO = 0.000000001 KAI
A transaction fee will be calculated by the following formula:
gasFee = gasPrice * gasLimit
The minimum gasPrice is 1 OXY (or 1000000000 HYDRO)
The minimum gasLimit is 29000 and the maximum gasLimit is 20000000
A typical transaction gas limit for sending KAI on the network is 29000
1000000000 * 29000 = 29000000000000 HYDRO = 0,000029 KAI
A smart contract operation or any transaction on KardiaChain network will cost gas for computing the logic in KVM.
    It costs zero fee to read data from a smart contract.
    Gas will return to users if a smart contract execution does not spend all the gas fee.
    If the transaction is processed but not enough gas to pay, it will be dropped (failed) and gas won't be returned.
