Crypto Asset Inheritance Platform

A non-custodial, multi-chain inheritance and contingency transfer system that lets asset owners define beneficiaries and conditions while retaining self-custody until the event is triggered.

Executive Summary

The Problem

Estate planning for digital assets is broken. A significant portion of crypto wealth becomes irretrievable upon the owner's death or incapacitation. Private keys die with owners; exchanges/custodians add counterparty risk and jurisdictional limits; DIY solutions are error-prone.

The Solution

A programmable inheritance layer supporting Bitcoin, EVM chains, and Solana, integrating with hardware, app, desktop, and browser wallets. The platform provides a non-custodial, multi-chain inheritance and contingency transfer system that lets asset owners define beneficiaries and conditions (e.g., timelocks, liveness checks, legal proofs) while retaining self-custody until the event is triggered.

Competitive Moat

Chain-specific primitives (PSBT + Miniscript on Bitcoin, Account Abstraction & timelock escrow on EVM, PDA-based escrow on Solana), legal-tech integrations, and a robust off-chain liveness/oracle framework. Non-custodial design ensures no counterparty risk while providing enterprise-grade security and compliance.

Business Model

  • • Subscription + event fees
  • • B2B white-label offering
  • • Enterprise API licensing

Target Traction

  • • Pilot with 100 power users
  • • 5 crypto-native funds
  • • $10–20M AUA in first 12 months

Key Features

Non-Custodial Architecture

Platform never holds usable private keys. All signing happens on user devices/wallets or via guardians. Self-custody until event trigger.

Multi-Chain Support

Bitcoin (PSBT + Miniscript), Ethereum & EVM L2s (Base/Arbitrum/Optimism/Polygon), and Solana (PDA-based escrow).

Programmable Policies

Define beneficiaries, asset lists, distribution ratios, proof requirements, dispute periods, and jurisdictional rules.

Trigger Mechanisms

Liveness checks, legal proofs, guardian quorum, timelock & escrow contracts with chain-native time/height locks.

Multi-Wallet Integration

Hardware (Ledger, Trezor, Keystone), app wallets (Phantom, Solflare, Rainbow), desktop (Exodus, Electrum), browser (MetaMask, Rabby).

Compliance & Audit Trail

Tamper-evident logs, encrypted document vault, exportable reports for executors and legal teams.

Architecture Overview

A modular system of Web/Mobile clients, an API/Orchestrator, and on-chain components across Bitcoin, EVM, and Solana. Wallet adapters integrate hardware, app, desktop, and browser wallets. Liveness/oracle services coordinate heartbeats and legal attestations.

On-Chain Modules

  • • Bitcoin: PSBT + Miniscript descriptors
  • • EVM: Timelock escrow & Account Abstraction
  • • Solana: PDA-based escrow programs

Off-Chain Services

  • • Liveness heartbeat scheduler
  • • Legal proof oracle integration
  • • Encrypted policy storage
  • • Audit/compliance logging
