Securing Crypto for Future Generations
HeirVault is a programmable inheritance platform that uses smart contracts to solve one of crypto's most overlooked problems: what happens to your digital assets when you're no longer around.
Our Mission
Over $400 billion in Bitcoin alone is estimated to be permanently lost in inaccessible wallets. As the crypto ecosystem matures and early adopters age, the inheritance problem grows more urgent every year.
Traditional estate planning tools — wills, trusts, lawyers — were designed for a world of banks and brokerages. They fail when applied to self-custodied digital assets where there is no institution to call, no password to reset, and no court order that can unlock a private key.
HeirVault provides a blockchain-native layer for programmable vaults with built-in dead man's switch, configurable multisig claims, and guardian oversight. No seed phrases to share with heirs. The on-chain flow follows your vault configuration, while legal and operational planning still need real-world review.

Core Principles
Non-Custodial
Your keys, your crypto. HeirVault never holds your funds or private keys. Assets live in smart contracts that only you control.
Open Source
All smart contracts are open source, built on battle-tested OpenZeppelin libraries, and verifiable on-chain. Trust the code, not the company.
Security First
Reentrancy protection, access control, and comprehensive test coverage. Every state-changing function is guarded against known attack vectors.
Multi-Chain
Open Beta vault deployment supports Ethereum, Bitcoin, Base, Arbitrum, Polygon, BSC, and Avalanche. Tron and Solana are available in beta.
