The Digital Succession Plan
The Digital Succession Plan — Full-stack developer
The Digital Succession Plan is an online web tool designed to securely store the crypto assets in a custodial wallet, with the opportunity to stake and swap the crypto assets. In the unfortunate event of a client’s demise, the tool ensures a smooth and legally compliant inheritance process. Assets stored in the custodial wallet will be transferred to the designated heirs of the Fund through a secure and lawful mechanism, eliminating the risks associated with traditional methods of passing on crypto assets. Inheritance of crypto assets is realized by having the client set up a private fund in Panama through the web tool.
