HeirChain
A guided estate-planning tool that helps crypto holders set up multi-signature wallets and encrypted inheritance instructions without writing a line of code.
Crypto holders with $50k+ in self-custody who worry about what happens if they die or lose access
- Step-by-step wizard to set up a 2-of-3 multisig across hardware wallets, with printable recovery cards
- Encrypted 'dead-man-switch' vault: if you don't check in for X months, instructions unlock for named heirs
- Lawyer-reviewable PDF summary showing on-chain balances, wallet layout and beneficiary plan
- Annual rehearsal mode that walks you (and a trusted person) through a fake loss event so the real plan is tested
The trending BIP-39 toolkit reflects the growing number of people self-custodying crypto, but the dominant fear in the community isn't generation — it's losing access or dying without instructions; very few products address the inheritance side.
Multiple authoritative sources (Wealth Management 2025 estate guide, Spark, Walletpilot reviews) confirm a real and growing pain point around crypto inheritance planning for self-custody holders, but it remains a niche subset of crypto users.Bitcoin After Death: 2025 Estate Guide - Wealth Management ↗Family Multisig Setup: A Practical Guide to Shared Crypto Security and Inheritance ↗
Market is more crowded than the idea suggests: Casa (with dedicated inheritance plan), Unchained (Personal Signature $6k/yr), Nunchuk, Sparrow, Liana, Jinca, and InheritWallet all already serve this exact need with multisig + inheritance tooling.Bitcoin Inheritance | Secure BTC, ETH, and Crypto | Casa ↗Bitcoin Inheritance Solutions Compared | Spark ↗Casa vs Nunchuk - Bitcoin Inheritance Services Comparison ↗
Strong willingness-to-pay evidence: Unchained's Personal Signature plan is $6,000 first year / $4,500 renewal, vault storage $250/yr, and Casa bundles inheritance into paid membership tiers.Unchained Pricing | Bitcoin Vaults, IRA, Trading, and Loans ↗Bitcoin Inheritance Solutions Compared | Spark ↗
Self-custody is structurally permanent, death/loss-of-access is a forever-problem, and estate-planning regulation/legal-doc integration creates durable moats.
Building a true no-code multi-sig setup wizard with encrypted inheritance instructions, legal document integration, and heir recovery UX is non-trivial — multisig primitives exist (Nunchuk, Sparrow) but a polished guided flow plus trust/legal layer requires meaningful engineering.
