Hidden wallet discovered — Trezor (2023)

Blocked

Case description

A UK executor in 2023 found a Trezor hardware wallet and a hand-written list of 24 words among the belongings of a deceased relative. Three months into attempting recovery, the executor discovered that the 24 words were not a BIP39 seed phrase—they appeared to be a mnemonic the deceased had created himself as a memory aid for a separately stored seed phrase that had never been found. The custom word list meant professional recovery tools could not be applied. The Bitcoin remained inaccessible.
