About
**Heirloom (DeFi Legacy)** is a cross-chain inheritance protocol that automates digital asset transfers using **cryptographic proof-of-life** mechanisms. It solves the long-standing problem of lost private keys and ensures secure, fair, and market-safe inheritance of crypto assets. Built as decentralized infrastructure, Heirloom combines **identity, smart contract logic, decentralized storage, and automated execution** to preserve generational wealth. Over **$100B+ worth of crypto assets** are inaccessible due to lost keys or death. Traditional inheritance systems fail because: - Private keys die with owners - No native crypto inheritance frameworks - Legal wills don’t work on-chain - Sudden liquidation harms heirs and markets Heirloom introduces: - Proof-of-life heartbeats - Automated settlement after inactivity - Age-locked inheritance for minors - Social recovery via guardians - Market-safe liquidation mechanisms All enforced **trustlessly by smart contracts**.
