Be careful using MEW to create Ethereum wallet and also opening them

[danherbias07]

I haven't opened my MEW account for months and my method was using the private keys.
I still have some valuable tokens there but some of it I already sent to another account.

Thanks for the warning but I got some questions.
Is this just for now, (the glitch part) or will this be a forever like problem?
Are we safe if we don't access it for a while and let it calm down for a bit?

I wonder what is the meaning of the error 'unexpected token b in JSON' could be.
Your keystore file format must be in JSON format, did you check whether the JSON format change or not ?
Does the coin balance still exist in your wallet ? If we want to using MEW, i think we need to save the keystore and private key separately in some safe place.

I'm still using MEW with private key. Luckily my wallet is safe until now. After reading your post i think i will find another wallet to use.

This problem just occurred only while using JSON?

I am now using Metamask taking out the risk of copy pasting my private keys since it is just a one time input.
Then, you will be using just a password for logging in the second time.

Before, I have the same method which is logging in with private keys at MEW which is risky. (MEW had a warning in their website)
Maybe you should try alternatives from now on.

If you are still safe, there is no need to look for another wallet, I also still use MEW until now using private key and I don't think to move to another wallet. The most important thing is you really keep your private key in a safe place, so I think it will be fine.

Is it possible to get all json file, private key and mnemonic phrase at once? Just in case we forgot one part of our wallet access code we can still use the others. But since I created myetherwallet before, I only granted one and just going to pick only from one choice. But they dont recommend private key anymore and using mnemonic phrase as advised.

But some wallet cannot be imported once you save Private key cause they only have mnemonic phrase as choice.

To answer this question, I think yes, I tried accessing my wallet created last 2018 using my Keystore file or the JSON file, I also got the same error prompt and wasn't able to open it. Luckily I also saved my private key and still able to open it using that method. I think the old JSON file is not supported now but I am not quite sure.

I think this should clarify some of the concerns of members although I would suggest reaching out to their support team for further information regarding that error for those who would prefer to access their wallet through JSON file,
However, I have been using my mew through private key, I believe it is still as secure as it use to be, it is a matter of being careful and visit the right website if you are accessing through the web or better yet use mew app, it is very convenient and handy as well.

OP already reached out to the support team about this issue, it is said that the file might be corrupted, but as per OP, he never edited those files, the same as mine.

From the last couple of years mew team has made some improvements in their wallet but it's still looks insecure with lot of bugs and it has higher chances to be hacked so it will be wise decision to not make this wallet as a permanent wallet these days we have much suitable options in crypto wallets which is much secure and user friendly than mew and recommended by mostly crypto community.

[Zeke_23]

I don't know why you save only the keystore file, maybe it is really corrupted or what,
'kay, it is given that you had previous experience of losing your funds because your private key was compromised but haven't you think that it is better to have another option to open your wallet and your private key will not be compromised if you put it to safety. Also, using keystore file is not recommended to use when you access your wallet.

[siddartha1492]

Did you try importing the file into other wallets like Enjin wallet? But it is certainly quite scary if json files are not working. What did their support say?

Yes, just keep the private key safe. I believe we will always be okay with MEW. I have been using MEW for many years and have never had any problems with it, recently I moved to the TRust wallet because it is so much more convenient.

Ever since I found out about Trustwallet, I've given up on them. Trustwallet has everything I need, simple and fast. Also they are managed by Binance so I always trust this wallet absolutely

This is my favourite. Apart from the fact that Trust wallet can be trusted and it can store ethereum and its associated tokens, it has the ability to stores coins from other chains. In fact, it is user friendly and has an inbuilt DEX for whoever wants to trade on it.
I do not know why people still use mEW, knowing the challenges and the insecurity problem it has been having. The OP's post is just a reminder to those who already know and a warning to those who are yet to know.

Oh, it is my nightmare to see messages like this. Personally i haven't use MEW for one year or even more, but now if i will need it i am warned.

[yazher]

I'm an old user of this site and I find it difficult to open my wallet back then till now. thankfully with some enough knowledge and extra careful when opening it, I didn't face a problem till now. but they really need to change their site's appearance to more user friendly because only those who had enough experience can use their site well. This will lead to confusion and some evildoers will take advantage of those who are not familiar with their site. from time to time they need to update their user if any new scamming attempts made to warn their users and prevent them to fall to such thing.

Actually it is not a nightmare for you, because with a warning like that you have been more careful in using it later, so it is not a nightmare because you have not had time to use it, hopefully you are not trapped into a fake MEW when using it.

You should try to download mycrypto desktop wallet and just try to open your keystore use mycrypto desktop wallet and i have been using it since MEW has made me feel inconvenience.

I hope that will be working perfectly.

Good idea! I have been moved to Mycrypto long ago, I really hate myetherwallet for many reasons. Though I love MEW connect and Mew wallet android app but their web version still looks vulnerable to me. Mycrypto gives better services than Myetherwallet. I think OP will get a good result in Mycrypto browser or the web version of it.  

[Santri]

I was surprised to see this because I have been using myetherwallet and I also don't have any problems, everything looks fine. the difference between me and you is, you use the keystore file and I only use the private key. I think the problem is not myetherwallet but the keystore file you have, maybe someone is editing it

I think the site is already user friendly enough for even those even with less knowledge to understand it, there are different option to open your mew wallet already given on the website, it is up to the user to choose which option they will use in opening their wallet, i have been using the private key option to open my wallet and never encounter any problem,
but as you said, they need to update users about any danger to prevent users from falling in the hands of scammers.
