Hardware Wallet Backup Complete — Bitcoin Never Left the Exchange
SurvivedBitcoin held by a deceased owner — heirs were able to recover access.
An estate executor discovered a Trezor Safe 3 hardware wallet in the deceased's bedside table alongside a 12-word seed phrase and PIN. Bank records showed a $1,000 purchase on Coinbase in April. Assuming the device held the purchased Bitcoin, the executor sought guidance on accessing and valuing the holdings for probate submission.
Initial advice correctly emphasized operational security: never share the seed phrase, never enter it via keyboard, use only the device's physical buttons through Trezor Suite and official documentation. This guidance addressed legitimate risks of seed compromise during the recovery process itself.
However, investigation revealed the critical custody gap: the Bitcoin purchased on Coinbase had never been transferred to the Trezor. The funds remained on the exchange under the deceased's account. The hardware wallet, despite being physically present and properly backed up, contained no Bitcoin and was unnecessary for recovery.
The executor subsequently gained access to the Coinbase account—aided by poor account security that required only possession of the deceased's phone—and retrieved the necessary information for the estate attorney. The Bitcoin was recoverable through Coinbase's account recovery procedures rather than through seed phrase restoration or hardware wallet access.
This case illustrates a common custody workflow failure: acquiring a hardware wallet and securing its backup without completing the transfer step. The deceased possessed both the device and credentials but failed to execute the critical movement of funds from the custodial exchange. From an estate administration standpoint, this made the Bitcoin technically accessible via the exchange's account recovery process, not the supposedly secured hardware setup.

The gap between legal ownership and operational access
Bitcoin custody was designed for use by its owner. The security model assumes that the person who set up the wallet is the same person who will use it. It does not assume that someone who has never interacted with the wallet will need to operate it months or years later, with no guidance and no one to ask.
The knowledge that dies with the owner includes more than credentials: it includes the understanding of why the setup was built a certain way, which addresses held the Bitcoin, whether a passphrase was set, where the backup was stored and why, and what the heir should do first. Without this knowledge, heirs typically face a search process before they face an access process.
Cases where heirs succeeded consistently share one feature: the owner had communicated the existence of the Bitcoin and left enough information for someone else to find and use the credentials. In most cases, this was informal — a note, a conversation, a letter in the files. Formal estate planning documents rarely contained the operational details needed for actual access.
The failure that causes heirs to lose Bitcoin is almost never the custody setup itself — it is the assumption that the setup is self-explanatory to someone who has never used it. Communicating the existence of the Bitcoin, its approximate location, and who knows how to access it adds almost no security risk while dramatically changing the inheritance outcome.
