Topic: How to choose the correct Gas limit for Ethereum. (Read 150 times)

Thank you for your excellent work. This information helped me to save my money. You help people and it is very important today. Now I know all the information about the gas limit. I hope that these calculations will not change, but now I see the gas limit on the site ethgasstation.info

Thank you very much for your answer.
It's great that I could help someone.
We all gathered here for this.
You can take my text, I do not mind)

This is excellent information for me. Why did not I think about this before? I want to take your article and translate it. This information can help many people. I hope you do not mind.
Unfortunately, I don't have a merit. But your work deserves a reward.

You must understand the main thing. You can use the most minimal gas limit. Your transaction will not take much longer. All gas limits for your transactions you can find on the site ethgasstation.info

Is there also indicator that when I'm sending other Altcoin to a exchanger aside from ETH  the gas limit will indicate the minimum gas need to pay for the transfer?

So if you want to save gas you can choose to put small gas fee instead of the minimum one and the only thing that will happen is that the transaction will be slower and it will take time for the receiver account to receive it?  That's what I understand on the last line of your's.

I really do not understand. Are you interested in finding out information only by bounty? I took the time to give you useful content. Let's react please. Give me feedback

You know that Bitcoin’s transactions are easy to – you just set the commission and wait for the transfer, but the Ethereum network everything works on a different way. Although the basic transaction method remains unchanged, the more commission money you are willing to pay means the passing the transaction sooner. But if Bitcoin was created as an alternative to traditional currency, then Ethereum's tasks are more global, and this platform was developed for the providing of various operations or executing smart contracts.

 There are three basic operations that can be performed on the Ethereum blockchain:
1. Transferring the ETH to other addresses.
2. Executing smart contracts.
3. Creating smart contracts.

Now we got to the main one. To perform these operations on the Ethereum platform, you will need to pay a commission, and the measurement of payment for any commission is gas. If you are performing a “heavy” operation, you need more gas. If your operation is simple, you need less gas. Everything is clear and not so difficult. This method confirms that network no perform useless actions and not use inefficient code.

This service – https://etherscan.io – contains all information about most transactions of the Ethereum network. Here example of such transaction with Gas value 22 251 (see Gas Used By Txn):
https://etherscan.io/tx/0x9b896be007157ca7c7a19880811c1add43c8f05323ecb08ec1befdb168dd4b09


Gas Limit determines maximum amount of Gas that can will spend for each transaction. This limit has its own specific value. When you transfer consists many transaction cycles, you will not lose a large commission. When you setting the Gas limit, it is important to understand a few moments:

1. For example, you set a limit of Gas 50,000, and you need for the operation 25,000. In this case, required amount of Gas (25,000) does not exceed the limit (50,000). This means that transfer will successful – the transaction will add to a block and will be executed, and the remaining 25 000 Gas will return to you in ETH.
2. Usually, when you select tokens for translation, the limit of Gas is setting automatically. However, if it value remains static, you should ask for smart contracts developers about the Gas limit, if you participate in ICO and other operations.
3. Remember that standard commission limit for transferring ETH to another address is 21,000 Gas. So if you plan just transfer ETH to different addresses without contacting smart contracts, it is important for you to remember that Gas Limit = 21,000.


The Ethereum divided for different parts:
1 ETH = 1 000 finne = 1 000 000 szabo = 1 000 000 000 gwei = 1 000 000 000 000 000 000 wei.
By the way, the names of little parts are real names of people who help to develop the cryptocurrencies.

Therefore, Gas Price is the price you are want to pay for one unit of Gas. Everyone determines for himself what price for a unit of Gas he wants to pay. Now 1 Gas = 20 Gwei, for standard transaction 21 000 * 0.00000002 = 0.00042 ETH ($ 0.219); here we mean ETH = $522.
This commission is not so big, but the question is – whether it is possible to pay less? For answer this question, we will use the next service: ethgasstation.info

In the table on the page, you can see a lot of numbers and letters, but we need only two:
Gas Price. We can adjust it with a slider. The measurement unit of this value – Gwei.
Gas Used. Amount of Gas needed to perform the operation.

If we set Gas Price for 20 Gwei and Gas Used at 21,000, the transfer time will be less than a minute (see Avg Time (min)), and the commission will be $0.219.

NB: What change if we set the price of Gas for 2 Gwei (in 10 times less than the standard value)? In this case, the translation time will be provide for 6 minutes (real time will be about 3 minutes).


This means that paying a commission of 10 times less you will wait for transaction confirmation just about 4+ minutes!
Of course, this is not ideal data. Time by time, data can be changed. This depends on high loading of the Ethereum network. However, why you should pay for Gas about 20-60 Gwei, if you can pay only 2-5 Gwei – and transaction will be not so slowly?

Now we have learned what is the Gas is and why it needs. In addition, you know how to send your transaction with little commission.

I hope the information was useful to you. I'm humble, but I'll be very grateful for the merit
