Why trust DieFi SeedShuffler?

DieFi and SeedShuffler is built by cybersecurity experts and has been audited by 3rd party security researchers and specialists. FortKnoxster, nor any of its staff, has no access to the information contained in the platform, as it is based on zero-knowledge principles. Basically, all data within the platform is one big “black hole”, as the data is end-to-end encrypted and protected by the latest encryption and security measures. Even if, i.e. a hacker should get access to the platform, no information can be seen, compromised, or downloaded. Nobody but you has the exact private keys to decrypt any information. Furthermore, the code is public to be read and audited by anyone.

How does it work?

Shuffle your original seeds into an unique number matrix, this is done offline.  Save your shuffled numbers (not your seed words)  in DieFi. Add yourself or other beneficiaries to your wallets, ledgers, NFTs etc. Now you have an automated crypto testament. You can edit ledgers, wallets, beneficiaries, Dead Man’s Switch timer, whenever you wish. Should you have an accident or die, we contact your beneficiaries after x months of no activity. And don’t worry; we will alert you many times before we initiate contact with your chosen beneficiaries.

I already have my self-custody own solution?

Great – But how? Wrote down your seed phrase and saved it in your house? Saved it your bank vault? Instructed your lawyer? Sent an email to a friend? Gave half the words to one friend and the other half to another friend? No matter what you did saving the raw word seed phrase is a considerable risk. There are humans involved. Humans make mistakes. Humans forget. Humans change. Humans turn dishonest. Humans die. And the list goes on. Covering your original seed phrase and eliminating the human element is the only secure way to future-proof your crypto assets.

What are the benefits?

Millions of dollars are lost daily as people forget their seed phrases, they get compromised – or people simply can’t find them. We make it easy and secure to store and update all your credentials in one secure platform.

How do you verify my beneficiaries?

The beneficiary verification is done online by a 3rd party security company, a market pioneer and leader in ID verification technology. Their technology is used in most airports worldwide to detect humans and detect ID fraud. Once your beneficiary has received notification from FortKnoxster (i.e., if you are dead) – your beneficiary must present their ID (passport, driver’s license, or alike). The ID gets analyzed and verified by over 100 checks using AI and other sophisticated techniques. Afterward, a real-time face scan is performed. Lastly, the beneficiary must answer a question to which only your beneficiary knows the precise answer. If the verification process pass, your beneficiary can access your DieFi account and all your stored crypto information.
