The Financial Reality

Costly Settlements

Families spend an average of $12,000+ settling a loved one's affairs without access to digital accounts and assets.

The EternaKeys Solution

Total Control

You decide who receives what, and when. EternaKeys executes your intentions with precision — no middlemen, no ambiguity.

Lost Assets

Billions Disappear

Billions in crypto and banking assets are lost annually because passwords and keys become inaccessible when their owners pass.
