Questions

Frequently asked

• What is the best crypto inheritance solution?

  The best solution depends on your needs. HeirVault offers the most comprehensive feature set with dead man's switch, multisig heir claims, guardian oversight, and multi-chain support. For Bitcoin-only users, Casa provides key management. Safe (Gnosis) is good for teams already using multisig but lacks a built-in dead man's switch for inheritance claims.

• How does HeirVault compare to Sarcophagus?

  Both offer dead man's switch functionality, but HeirVault adds multisig heir claims, guardian oversight, Bitcoin support, and 9 live vault networks including Solana and Tron. Hyperliquid metadata is tracked separately until a deployment factory is configured. Sarcophagus requires sharing encrypted secrets, while HeirVault keeps funds in user-controlled vault contracts with no seed phrase sharing.

• Can I use a regular multisig wallet for crypto inheritance?

  A multisig wallet like Safe (Gnosis) can be used for inheritance by adding heirs as signers, but it lacks a built-in dead man's switch. Heirs must coordinate manually. HeirVault enforces the claim flow on-chain: if you miss a check-in, heirs can begin the inheritance claim process.
