Question 1

Does the manufacturer pinky promise not to remember the private keys after manufacturing these?

Accepted Answer

Ballet’s innovative two-factor key generation process (2FKG) was designed to eliminate the risk that a rogue employee or a criminal who gains access to our secure manufacturing facilities could steal encrypted private keys or passphrases. There are multiple layers of protection built into the process.
Ballet’s two-factor key generation process requires the encrypted private key and passphrase to be generated separately on offline, air-gapped computers in different locations on different continents by different employees. These two components of the private key are never exposed to the internet or commingled on the same computer or hard drive. Therefore insider theft would require multiple employees to collude, and outsider theft would require both locations to be compromised secretly and simultaneously.
Encrypted private keys and passphrases are deleted and overwritten immediately after the manufacturing process. The only copy that exists is contained in non-electronic form on the physical Ballet wallet itself, concealed under the tamper-evident sticker and scratch-off. Therefore even if criminals break into the manufacturing facility, there will be no encrypted private keys or passphrases for them to steal.
Only a very small number of Ballet’s most experienced and trusted employees are involved in any part of the private key generation and manufacturing process. They have strong incentives to ensure that every wallet produced is secure. If an insider theft ever occurred, it would soon be discovered which employees were responsible, and they would face severe criminal penalties. It would be impossible to commit the crime and get away with it.
Every Ballet employee has a financial and reputational stake in the success of the company, and the success of the company depends on trust. If Ballet customers ever lose funds due to theft or product defect, all trust in the company would be lost and employees’ financial stake would be worthless. Our interests are completely aligned with our customers. Therefore everyone at Ballet has a strong incentive to ensure that standard operating procedures and quality control standards are strictly adhered to at all times.

Question 2

If I’m buying this for a friend, can I load the wallet up with a coin without having to download the app? Is the public wallet address visible?

Accepted Answer

Hello,

Yes, you certainly can! Tear off the flap on the front of the package to reveal the wallet’s cryptocurrency address QR code. Then you can deposit cryptocurrencies to the wallet and give it as a gift with the external package still intact.

I hope this info helps.

Kind regards,

Question 3

How much bitcoin can you store on each card/wallet you buy? Will one card store all of your bitcoin?

Accepted Answer

You can store as much bitcoin on one card as you want,You're not actually storing any bitcoin on the card the card has your private keys which if someone steals or you lose  your card you lose all your bitcoin.In my opinion this cards is not safe to keep a large amount of bitcoin only a small amount.You should use a hardware wallet like ledger To store larger amounts of bitcoin Safely Follow all the security procedures ledger recommends. Never reveal your private keys or seed words to anyone or you will lose all your coins.

Question 4

Is it a must to use with ballet app?  can you use other apps like exodus to withdrawn from the private key?

Accepted Answer

Hello and thanks for your question. No Exodus does not support BIP38, so it is not possible with this particular one. Coinomi and Mycelium however support this, so with these wallets, it is possible.
