Crypto Key Inheritance (Paid Features)
Your Time Capsule for Yourself or Your Trusted Circle
PurrVault is a cloud-based, end-to-end encrypted (E2EE), decentralized storage system designed as a secure group chat for long-term key storage. Vault owners can create secret notes and set custom unlock conditions like multi-signature approval or time delays.
Use it with trusted members or your own multiple accounts to create a personal, self- recoverable vault—ensuring secure access to your private keys when needed.
Your Time Capsule for Your Heir or Designated Recipient
Ensure your crypto keys are delivered — even if you're not around. PurrMail is a fully E2EE, decentralized mail system for crypto inheritance. Send seed phrases or instructions with timed or trigger-based delivery. Messages stay encrypted and inaccessible until all conditions are met.
"For the final message that matters most."
