Creating smart contracts is an exciting topic, especially for developers. Etherscan might be very useful in this regard — it shows you everything you want to know, even transaction code , so you can check what happens there at any time. When you add the transaction to the block, the required code will be executed if we are talking about a smart contract.

The amount of gas used for the contract is then converted to ETH and charged to your account as miner reward. In a way, the gas limit serves as a transaction fee limit. If you set your limit at 1,, gas and the smart contract needs only 50, gas, then you will pay only 50, The purpose of the gas limit is to secure users from spending more than they can afford a smart contract may cause an infinite loop, which would get a user in trouble. Unfortunately, if the contract needs 1,, gas to execute the transaction, then you would spend gas, but the program would not finish its work.

As a rule, developers specify how much gas is needed to execute their smart contract. Why pay more? Just like Bitcoin, Ethereum has a transaction pool. Below you see the picture from MyEtherWallet that shows how the transaction is executed. You choose the gas price based on how fast you want the transaction executed. At the price of 12 Gwei or more — 2 blocks. Remember that the current block finding time in Ethereum is 15 seconds, which means that even if you choose to pay the lowest fee 0.

In fact, it is hard to understand why so many users would pay 50 Gwei for gas check out the transaction pool. By the way, ETH Gas Station has a table in the lower right corner that shows various stats for the last 2, blocks.

The transaction used 92, gas. Here it is on Etherscan. The Ether transaction pool is not very big yet, but it is likely to grow in future. Look at the latest blocks :. Instead, they use gas. But in reality the blocks are often not filled to the fullest:. The transaction line is short. If the gas price equals 1 wei, then regardless of the amount of gas needed for your transaction for the simple transaction you need 21, gas , the fee will be extremely low!

You can go to the Send Offline section and set the gas price in wei, not in Gwei:. Special thanks to Erik Van Daal, the lead developer of 2Masternodes.
