Where your seed begins
Randomness is the root of security.
Your Seed Phrase is the backup used to recover your Wallet. If its randomness can be predicted, every Wallet derived from it may be at risk. ELLIPAL Joy draws yours from real hardware noise in the ST chip, so it stays unpredictable and known only to you.
Open source
Don't trust. Verify.
ELLIPAL Joy's code is fully open source. Anyone can inspect how each phrase is made and verify it on GitHub. Do not take our word for it, check it yourself.

We appreciate your feedback! We make the program public so that anyone can check the generated rules. Offline generation of JOY could prevent network attacks and provide absolute security.
Love this device, even though seed phrases are usually given to you at the time when accounts are open. What would be awesome if Ellipal added a password generator as well.
The joy nmemonic generator works real well. I think it is an excellently engineered product.
I am not convinced that true random really matters, but what matters is that you will know your words were not pre-programmed.
Also be careful that mnemonic words on one wallet do not always transfer to a wallet by a different maker. Do a little testing first with various wallets and a little funds.
I bought this for extra security, being able to make my own pass-phrases offline. It’s open source and what an easy product to use. It’s well worth the money to be even more secure. It’s an addition I’m glad I added to my order!
The Ellipal Joy is a fun little gadget, albeit mostly useless :)
+ Beautiful design
+ Very intuitive to use
+ Software is open-source
- No guarantee that it runs original software (no tamper seal, no trusted boot, ...)
- No guarantee that it generates truly random keys. There could be a backdoored RNG for all I know.
Store owner replied:
Thank you for reviews, Since the Joy is open source, You can check the source of generates truly random keys. or you can also import your own BIP39 Standard code.
Good product to generate offline your 12, 15, 18, 21 , 24 seedphrases. Looks cute and is easy to use :D
Amazing product. I did not even know that a great product is available in the market. I always doubted preset mnemonic phrases. This is a very good solution for that. It does not matter whatever the hardware or software wallet you use, it is always better to generate the mnemonic phrase from this device. So you are 100% risk-free & this is an open-source product. Thank you Ellipal
A simple yet super important little safety cube.
Now i know why it's name Joy as it solved all my problem.
Btw, hope the price can be reduced to $29.90 as i will buy 10 for my next Christmas gift~

It's actually very easy to use. The problem with most wallets is that the mnemonic generation isn't secure, offline, or open-source. This device simply solves all of that security issues. A pretty simple yet very smart and creative solution!
Store owner replied:
