Send ethereum with zero fee

[ch_mubarak]

Some of you may notice some guys sending ETH and tokens with 0 gas(zero fee).

Here is some tx id check it.

Another one with 1 wei (0.000000001 Gwei)

Do you wonder how they do it??

If you are using MyEthereWallet you can lowest set to 1 Gwei, but with MetaMask you can set to 0.1 Gwei

For lowered Gas Price you need to use the web3 APIs directly. For my transactions I have used web3j API (https://github.com/web3j/web3j) which is the API for Java. Below is the code snippet of web3j program that I used to send the transaction with 1 wei.

Here is the code for send eth with low fee

Nb:I specifically send with Gas Price = 1 wei only and this got mined within 10 mins of waiting time on the network, this was possible since Ethereum network was not having congestion during that time.

Heпoнятнo для этoгo нyжнo cкaчaть кaкoe-тo пpилoжeниe?

Well apparently can send ethereum with zero fee.
Have a video tutorial?
and also whether the way is really safe? I still doubt.

[bitcoinner786]

I am looking forward to ETH will not charge transaction fees. But there will be no such thing, because the transaction fee will help the developers to develop

[Coingram]

Yeap thats possible as we can see at the transactiions info, but you need to install metamask if you dont have it, and upgrade some apis, wish that possible with eth platform tokens too

[anggriani]

very interesting to use in bulk, but how about the speed of transactions, whether fast or slow?
some days I have a problem in MEW, I can not send the token and always fail, even though the gas is set up high, does anyone have a problem like me?

[melamiras]

Not with zero fee that´s for sure, you are going to use at least 25000 gas and that means that you will always spend some eth, even if it is just a little bit due to low congestion.

Thanks for interesting topic. I'll try to understand at leisure. Always wondered how some can send tokens with a practically zero commission. Now, it seems, I'm beginning to understand how this is possible!

[tysavbde]

In recent days, the cost of gas is very high. If the efficiency of API is very high, it can overcome the problem of ETH's high transfer cost recently.

[ka4ok1331]

I don't think it would be possible to do this for a long period of time. First of all because Ethereum has big problems with speed and your 0.1 fee will make your transaction go forever

[macit800]

On that way is the fee zero, but look at the timestamp. It can take up to 5/6 days before the transaction succeed. It is always better to put the gas higher and that the transaction succeed fast. If you have days to wait, then you can do it on this way.
