Passing on Bitcoin as generational wealth demands strategies beyond simple storage. With trillions transferring from older to crypto-friendly generations, self-custody inheritance protocols provide the secure path forward. These tools ensure assets reach heirs privately and reliably, avoiding the traps of collaborative models. Collaborative custody solutions have marketed themselves as an easy fix, promising distributed keys and assisted recoveries. Yet they require trusting providers to generate private keys securely, hold keys long-term on servers, expose balances and history eroding privacy, and face KYC or jurisdictional shifts. Will heirs be able to rely on the company and their servers to be up and running decades later? Superior approaches rely on offline encryption and easy-to-use sharding solutions, integrated into wills for legal enforcement. No ongoing service dependencies mean resilience against company failures or regulations. Heirs gain straightforward access via verified proofs, preserving Bitcoin’s sovereignty while securing family legacies. This offline solution aligns perfectly with Bitcoin’s ethos of “not your keys, not your coins,” empowering individuals to maintain full control without intermediaries.
