Prepare for the future - Don't lose your crypto when you die...

...unless you set up Crypto Inheritance today.

It's simple — if you don't worry about crypto inheritance, nobody else will — not your software or hardware wallet vendors, not your exchanges, and not your wealth managers. So it's up to you to think about how to protect the generational wealth you have created, and reduce the risks around passing that crypto wealth on to your family and heirs. What are the challenges with crypto inheritance?

  • Crypto Wallets are difficult to use and do not offer crypto inheritance management. In fact, most of them tell you to write down your seed phrase on a piece of paper, which is practically useless.
  • Some people back up their wallet seed phrases or private keys on paper, local devices like hardware wallets or USBs, or in the cloud. All of these options have severe drawbacks that range from hacking to accidental loss to disrupted cloud services.
  • Software wallets operate on specific blockchains, yet your crypto assets span multiple blockchains. For inheritance to work, you must be able to manage inheritance across every blockchain — now and forever.
