I found the safest way to get your 24 word seed phase.

[MisFoxie]

I have been researching about how i can genarate a 24 word of seed phase without a ledger wallet and i found an interesting way to do that. Let me share the detailsso you don't have to waste your time like I did.

First you need a clean device then go to  https://github.com/iancoleman/bip39/releases
And download bip39-standalone.html (if you have clean windows/mac system you can download sparrow wallet it can do the same thing)


Then turn on airplane mode so you can genarate a 24 word seed phase safely.

Open > bip39-standalone.html with chrome or any other browser.

On the genarate section you see 15 make it 24. And click genarate it will genarate random 24 word seed phase. If you scroll down a little you can see coin section it automatically set as Bitcoin you can change it to Ethereum (though It doesn't matter to me I only need seed phase

After you get your seed phase write it down on a paperor a metal. Clear Data of your browser which you used.

Turn on your internet and download any Bitcoin supported wallet (eg: Sparrow wallet, Electrum wallet, blue wallet )

Again turn on the airplane mode (so that all your internet connection get cut off again)

 Write seed phase in any of these wallet and you can see the reciver address (You could see this address in bip39-standalone.html after you genarated the seed phase also)

After you see the address you can copy that address for Receiving you fund leter.

Clear data of that wallet also. ( So that when you go online no one can have any access to them)

If you want to check your fund check it on a block explorar. (Don't use your seed phase online)

I will not try to do anything manually by myself if I am not an IT guy.

There are many open source and non custodial wallets which are good and trusted with ability to make my wallet creation process more easily and safely. I would like to choose wallet softwares for this task, and avoid exploring manual configuration steps by myself like you recommended.

I want to have a wallet that can store and keep my bitcoin safely, and I don't want any cool thing but less safely.
Recommended wallets.
What are best Bitcoin wallets?

In fact, the method you found was discussed in a previous thread, and in that discussions, you can also find some safe suggestions for obtaining a seedphrase, or private key. Here, are the reference I am referring to : bitcointalk.org - info about Ian Colman mnemonic ( You need to pay attention to these suggestions, so that you can avoid risks, keep dyor )

In another thread, you can also find it, but regarding a detailed discussion regarding several explanations of the tool, here it is : bitcointalk.org - Need help with iancoleman

There is also a discussion about the official website related to the tool, I hope you read it too, maybe the discussion is quite old, but you need to know, because there may be fake sites in the future : bitcointalk.org - Is Iancoleman BIP39 Site Changed Domain from .io to .ch?

I wouldn't consider this thread as a topic for "beginners and help" because as tbct said above "I would never try a manual setup configuration if I am not an IT guy". I would rather prefer to discuss the major potential risks of relying on this manual setup for a beginner far away from technical expertise. Maybe somebody wants to try it out of curiosity or to learn something new, but this is not the right board to get information from. There is already a great board dedicated only for technical discussions: Development and Technical Discussion

While the iancoleman script, after properly verifying the downloaded version (check it matches the hash), is a well known one and it's code is tested, you still rely on the correct Javascript implementation of crypto-safe random generator function therein.

It shouldn't be bad, but hardware wallets usually implement better entropy and most of the times also a hardware random number generator.

Then turn on airplane mode so you can genarate a 24 word seed phase safely.

You don't make an online device suddenly safer when you turn off network connectivity. If your device already had malware on it, the malware can still do its evil things and just wait until you turn off airplane mode. That's not a new trick for malware.

Open > bip39-standalone.html with chrome or any other browser.

How about browser extensions? Did you think about those, if you have some? Many browser extension ask for the right to read anything of your web pages. Guess what this means if your iancoleman script generates something that shouldn't be disclosed to "foreign" parties.

Can you trust the code of your browser extensions?


You need to start a safe and best an agnostic (doesn't persistantly store or remember something) environment to create your mnemonic recovery words. Boot a live Linux which only runs in RAM: if properly verified (check hash of the ISO file), it should be safe and when you shut it down, usually nothing remains on your computer (don't forget to write down your mnemonic recovery words on analog paper, no screenshots, no digital files, no upload anywhere).

Proper computer safety isn't convenient and easy, sorry!

thanks for your genuine reply, I agree with you that even if im offline malware can steal my information but I already said that you need a clean device. and by clean I mean a device that doesn't have any malware or have been compromised.

well browser extension can cause problems, a clean device should not have a extension though.

This method is quite interesting. I also tried this one by making my usb pendrive a bootable pendrive. it works quite well. this could be hard for some users, so I didn't give the instructions
