Memory Paper Wallet

Customizable Paper Wallet for Bitcoin Segwit, Ethereum, Monero, Litecoin, Ardor/Ignis

Live Site: https://goo.gl/dgDnhb

Source: https://github.com/xcubicle/memorypaperwallet

We've all run into the issue of gifting bitcoin to friends or family at one time or another. A lot of the times, newcomers have a hard time grasping the concept of "digital" money. They think if you can't feel it physically, it isn't "real". Paper wallets are the best way for beginners to get their feet wet into cryptocurrency. Since they can hold it and see it, its a much easier segway into this new concept of "digital money".
 
Originally we were giving out bitcoins on paper wallets to friends, family, and businesses, but the online tools were lacking in aesthetics in terms of being able to customize your own paper wallet. Also a lot of the times, we ran into the issue of just "throwing" away money as these people didn't take it seriously and just lost their private keys. They eventually realize their 20 cents worth of bitcoins was worth a significant amount, they ended up asking if we still had the coins we gave them.
 
This was the motivation to create a paper wallet generator to solve this problem. The ability to have a "master passphrase" to regenerate their keys if they lose it in the future and the ability to use your own custom artwork for birthday, wedding, or Christmas gifts.
 
Basing our work on Warp Wallet and Memwallet. We managed to retro fit these brain wallet generators with new enhancements for everyday use. Keep in mind these paper wallets are meant to store small insignificant amount of coins which are meant to be given away as gifts or for short term storage. Even with a simple 8 character passphrase, the scrypt address generation is meant to be memory and time-intensive so others can't easily guess your secret. This is why paper wallets should only be meant to store insignificant amounts to be used as gifts.
 
Main Features:

- Custom printable artwork.
- Passphrase recovery
- Bitcoin segwit paper wallet support.
- Litecoin, Etherem, Monero, and Ardor/Ignis Support.
- Identicon implementation. Visually identify your address.

From my first tests it looks good. I may test it further one of the days, since I like the idea.
I would have preferred to not have the e-mail calculated into the private keys generation, but that's me (I have too many e-mail addresses).
All in all, well done!

thanks. you don't need to put your email if you don't want to. you can literally put anything and don't even need a passphrase. i just chose email as its something everyone remembers.

i was thinking maybe to run a contest just for fun on who can make the coolest paper wallet artwork.

I will look into the code, at least to the level of what input is used, hopefully someday even deeper.

Well, it could be a nice advertising, but that's not really my field.
I checked it, I liked it, I packed and copied it to keep it safe, since I may used it someday - for its real life use or to learn more.

Nice software. I think it's more simple and attractive compared to similar software/service and open source code/can be used offline are good value.
However, there's UI problem when i try make paper wallet whether on your website or run it locally on Mozilla Firefox 59.0.2 64-bit

Oh totally forgot.. firefox can't render webp images... only google chrome can. webp image format is highly compressed images. This is how i can get this application be be less than 1.4mb in size.

It can fit on a FLOPPY disk!

That's lovely project Smiley

However, I would discourage the usage of brain wallets unless you force users to pick 12+ random words.

Shamir Secret Sharing is now working with the paper wallets. You can split a private key into 2-9 parts and recombine them with 2-4 if you want. Good use case if you want to secure your coins among different parties.
