Your Crypto Outlives You
Billions in crypto are lost every year — not to hacks, not to rugs, but to death. Private keys die with their owners. This is different: you don’t share your keys, you don’t hire a lawyer, you install a time-locked policy.
Pitch of the Core Idea
The crypto inheritance market is projected to reach $26B by 2025, part of the broader $29.5B digital legacy industry by 2030 (18.6% CAGR). $6T in digital assets will transfer between generations. Yet every solution has the same flaw: they require you to trust someone with your keys while alive, or demand legal infrastructure that defeats the purpose of decentralized finance.
This is different. You authorize a designated heir — family member, friend, charity — to empty your wallet after a countdown expires. The countdown is long: 5-10 years. As long as you’re alive and active, you push the deadline forward with a single signature. Any on-chain activity counts as proof of life: swap, transfer, DeFi interaction, even micro-payment. The heir never has access until the clock runs out. You never surrender custody. The smart contract is the executor.
Core Mechanics
- Set the heir: Specify wallet address that can claim after deadline
- Set the countdown: 10 years from now, heir’s claim window opens
- Stay alive, push the deadline: Any on-chain activity resets/extends timer
- Go dark, they inherit: If deadline passes without reset, heir submits claim. Entire wallet balance transfers automatically
Configuration options:
- Multiple heirs with different percentages
- Cascading deadlines (primary claims within 5 years, backup after)
- Conditional inheritance (heir gets funds only if their wallet has activity — proving they’re alive)
- Alerts: 90 days, 30 days before deadline expiry via Telegram
Psychological Hook and Addictiveness
“Your crypto outlives you, and YOU decide where it goes.” Hits something primal. People don’t just want to protect wealth — they want to control what happens after they’re gone. This offers a third path: program your intent into the chain and let the code execute when you can’t.
Annual “push the deadline” ritual: A moment of reflection — “I’m still here, my assets are still mine, my plan is still in place.” Like renewing a promise to yourself and heirs simultaneously. Heir engagement: Heirs monitor the countdown, creating unique relationship with the protocol. Refinement loop: Users tweak allocations, add heirs, adjust deadlines — becomes a living document evolving with life changes.
Brief Market Research
| Metric | Data |
|---|---|
| Crypto Inheritance (2025) | $26B |
| Digital Legacy Market (2030) | $29.5B |
| CAGR | 18.6% |
| Digital Assets Transferring | $6T |
| Crypto Ownership (US adults) | 18% (up from 12% in 2022) |
Key Competitors:
- Cipherwill: Digital will platform, web-only, encrypted vault, but not crypto-native
- Inheriti: Blockchain-based inheritance using Shamir’s Secret Sharing, VeChain/Ethereum/Polygon, but complex
- DGLegacy: Password manager + inheritance, heartbeat monitoring, $5.99/mo
- AbsentKey: Dead man’s switch without check-ins, recipient-initiated requests
- Safe (Gnosis): Multisig with social recovery, but requires trusted signers while alive
None provide non-custodial, time-locked inheritance without trusted intermediaries.
Business Model
- Setup fee: $50-200 one-time for policy creation
- Annual maintenance: $10-50/yr for monitoring and alert services
- Premium features: Multiple heirs, cascading deadlines, conditional inheritance ($100-500)
- Estate planning integration: $200-500 for lawyer-reviewed policy templates
- Heir verification: $20-50 per heir identity verification
Summary of Technical Specifications
Architecture
- Time-locked policy engine (ComposablePolicy with countdown + reset mechanism)
- Activity monitor (detects on-chain activity from owner’s wallet)
- Alert system (Telegram notifications at 90/30/7 days before deadline)
- Claim submission interface (heir submits claim after deadline)
- Multi-heir support (percentage-based distribution)
- Emergency controls (owner can pause/revoke at any time)
How This Hooks Into Tributary
- Milestone: Time-based release condition (deadline expiry)
- PayAsYouGo: Activity monitoring for “proof of life” detection
- ComposablePolicy: Defines heir addresses, percentages, deadlines, conditions
Recommended Tech Stack
- Solana + Anchor
- Tributary SDK (Milestone + PayAsYouGo)
- Activity monitoring service (watches owner’s wallet)
- Telegram bot for alerts
- React interface for policy management
- On-chain clock/timestamp verification
MVP Scope
- Single heir, single countdown (10 years)
- Activity-based deadline reset
- Basic alert system (email/Telegram)
- Claim submission interface
- Buildable in 2-3 days with Tributary SDK
Non-Technological Requirements
- Legal review: On-chain wills have no established legal precedent. Family members could challenge in court regardless of smart contract
- Estate planning integration: Need to work with existing estate planning frameworks
- User education: Users must understand key management — if keys are lost before death conditions trigger, protocol is worthless
- Heir communication: Heirs need to know about the policy and how to claim
- Regulatory awareness: Inheritance law is jurisdictional and heavily regulated
Potential Risks
- Premature claim exploit: If reset mechanism has bug, heir could claim while owner is alive. Multiple confirmation layers essential
- Lost access while alive: Owner loses key but is alive. Countdown runs out, heir inherits. Needs “pause” mechanism via alternative verification
- Heir wallet compromise: Designated heir’s wallet gets drained before claiming. Needs claim-window time limits and revocation options
- Legal ambiguity: On-chain wills have no established legal precedent. Family members could challenge regardless of smart contract
- Regulatory collision: Inheritance law is jurisdictional and heavily regulated. Trustless protocol bypassing probate will attract legal attention
- Countdown anxiety: Some users find ticking clock psychologically distressing. UX must emphasize user control, not mortality
