Why I built EternVault: crypto inheritance without key custody

Crypto inheritance still feels broken. Most options are either manual and fragile, or they require giving custody of keys to a third party.\n\nI built EternVault to make the inheritance workflow verifiable without taking custody of assets or private keys. The live version supports Polygon, Base, and Arbitrum, uses heartbeat-based monitoring, adds a 14-day confirmation window before final signal emission, and only lets beneficiaries recover the key package after the on-chain status reaches SignalEmitted.\n\nI also shipped offline decrypt tools for Windows and macOS so beneficiaries can decrypt locally instead of trusting a hosted flow.\n\nIf you've thought about estate planning for crypto, I'd like feedback on two things:\n1. Which part of the flow feels hardest to trust?\n2. What would make the beneficiary recovery path clearer for non-technical family members?
