On-Chain Digital Inheritance

On-Chain Digital Inheritance represents a transformative application of blockchain technology that moves beyond conventional asset distribution.

Rather than merely mimicking traditional wills in a digital form, this approach reconceptualizes inheritance through tokenization —creating digital representations of any asset with cryptographically enforced conditional transfer.

Through smart contracts and architectural time-locks, beneficiaries receive provable, conditional access to tokenized assets without requiring custody arrangements or ongoing institutional dependencies.

This system is not limited to cryptocurrencies or digital files. By leveraging tokenization, it securely manages and transfers rights to any asset—real estate deeds, intellectual property, tangible property, or access credentials—through universal blockchain infrastructure.

By fusing legal intent with programmable enforcement, on-chain inheritance represents a fundamental advancement in estate planning. It elevates ownership from institutional documentation to cryptographic certainty, creating a future where rights and responsibilities seamlessly pass across generations through verifiable, immutable, and autonomously executing systems.

Inheritor makes it simple, the blockchain makes it bulletproof.

Download the app

Connect your beneficiaries

Add a beneficiary by scanning a QR code or accepting an invitation.

Connections are secured with end-to-end encryption. Only your designated beneficiary holds the keys to access the inheritance.

Add your inheritance

Select files (documents, videos, crypto wallet info, codes etc.) and add personal notes. Updating your digital will is refreshingly simple. Adding new inheritances, or revoking existing ones, takes just a few clicks.

Your documents including any secrets are encrypted and stored on the Arweave blockchain, ensuring they can’t be viewed, lost, altered, or deleted.

Don't trust, verify!

Inheritor provides all information you need to verify your inheritance on the blockchain.

We provide every detail, from the smart contract address to the transaction hash. With direct links to block explorers to view the immutable record of your inheritance for yourself. We don't just promise security - we provide the proof.

Check-in or pass-on

The app will notify you to confirm your wellbeing. Only under the conditions you have set, the inheritance becomes accessible to your beneficiaries.

Inheritor uses a smart contract on Arbitrum or Ethereum for maximum security, that executes your digital will only when prudent.

Claim when prudent

Verify if an Inheritance is claimable. If so, the smart contract releases the inheritance, the asset is decrypted and will be accessible only for the beneficiary.

Your inheritance is sealed with AES-256-GCM encryption, the gold standard for protecting classified data. This provides two essential guarantees: confidentiality (it's unreadable to anyone else) and integrity (it cannot be secretly altered).

FREQUENTLY ASKED QUESTIONS

We have answers for you:

On-Chain Digital Inheritance is the blockchain-based evolution of traditional estate execution through asset tokenization.

Traditionally, asset transfer after death is overseen by human intermediaries: notaries in civil law countries, executors or personal representatives in common law systems. Their job is to ensure your will or estate plan is carried out.

With Inheritor, this executor role is replaced by a smart contract. Assets are tokenized—represented digitally on blockchain infrastructure—enabling the blockchain to act as an incorruptible executor, enforcing your instructions automatically, transparently, and without delay.

Importantly, lawyers can still draft wills or deeds. Inheritor doesn't replace the creation of legally valid documents: it tokenizes and autonomously transfers them, replacing the costly, slow, and fallible human administration that follows.

Your Digital Will in Inheritor can include both digital assets (cryptocurrency wallets, access keys, encrypted files, online accounts) and physical assets (via pre-signed deeds). By tokenizing these assets and entrusting execution to blockchain automation, you ensure loved ones receive what you intend—safely, verifiably, and at the right time.

It's estate planning that matches the realities of our connected lives.

Accidents, by their very nature, strike when we least expect them—yet most people postpone inheritance planning because it feels daunting, expensive, or tied to lawyers and notaries.

The burden on your loved ones goes beyond grief. They face your digital life—computers, phones, bank logins, crypto wallets, PIN codes—plus physical affairs: property, valuables, business responsibilities.

Traditionally, intermediaries handle this: notaries in civil law countries, executors in common law systems. But this process is slow, costly, and vulnerable to human error. Worse, it often fails entirely for digital assets: cryptocurrency wallets get lost forever, online accounts become inaccessible, encrypted files remain locked.

Inheritor changes the equation. A smart contract replaces the human executor—automated, incorruptible, and transparent. For assets requiring formal deeds (real estate, titled property), lawyers can still draft legal documents that Inheritor releases automatically.

For digital assets like cryptocurrency, encrypted files, and online accounts, you create inheritances directly from your phone—no lawyers, no notaries, no institutional dependencies.

This isn't just planning for yourself—it's a profound act of care for those you leave behind. You give them clarity in confusion, and the ability to move forward with stability and dignity when they need it most.

Anyone who wants to ensure their intentions are carried out—for digital assets, physical property, or personal belongings—should use Inheritor.

What you can include:

Digital assets where access = ownership: Cryptocurrency wallets, encrypted files, online accounts, domain names
Physical property: Cars, jewelry, collectibles, family heirlooms—Inheritor releases your instructions and any supporting documents to beneficiaries
Registry-bound assets: Real estate, titled vehicles—Inheritor can release pre-signed deeds or transfer documents to beneficiaries, who then complete the legal registration process
Personal instructions: Who gets what, where things are located, access credentials, final wishes

Why Inheritor specifically?

Traditional inheritance works reasonably well for property with clear paper trails. But it fails catastrophically for digital assets (crypto keys, encrypted files) and struggles with personal instructions that need secure delivery.

Inheritor ensures your expressed intentions reach the right people at the right time—automatically, transparently, through blockchain enforcement. For assets requiring legal paperwork (like transferring a car title), beneficiaries receive your documented instructions when conditions are met, then handle the necessary registration outside Inheritor.

The real value isn't replacing lawyers or DMV processes—it's guaranteeing your wishes are known and accessible when you're not there to explain them. Whether that's crypto wallet keys, the location of your car title, or which family member should inherit grandmother's ring.

A traditional will is a legal document stating your intentions—but it still requires human execution. In civil law countries, a notary administers the estate; in common law systems, an executor or probate court handles distribution. This process is slow, costly, and dependent on institutions remaining operational.

Inheritor replaces the human executor layer with a smart contract. Your intentions are still documented (and for certain assets, still drafted by lawyers), but execution becomes automated, transparent, and guaranteed by blockchain—no human intermediary required.

Key differences:

Traditional Will:

Requires probate court or notary oversight
Executor/attorney holds responsibility
Process takes months or years
Depends on institutions staying operational
Recurring (high) legal/administrative fees

On-Chain Digital Inheritance (Inheritor):

Smart contract automatically enforces conditions
No human intermediary controls execution
Releases immediately when conditions are met
Operates through public blockchain (no company dependency)
Much cheaper via easy in-app subscription

This matters especially for digital assets where access equals ownership—cryptocurrency, encrypted files, online accounts. Traditional wills struggle with these because lawyers/executors can't safely hold crypto keys, and password services require trust and subscriptions.

But Inheritor handles all asset types: digital assets (complete autonomous transfer), physical property instructions (releases documentation to beneficiaries), and registry-bound assets (releases pre-signed deeds for legal registration).

The fundamental shift: you're not trusting people or institutions to carry out your will—you're trusting math and public blockchain infrastructure.

Inheritor is the first iOS app that implements On-Chain Digital Inheritance—using blockchain smart contracts to replace the traditional executor/notary layer in estate administration.

Here's what that means practically:

From your iPhone, you create inheritances for beneficiaries—whether that's cryptocurrency wallet keys, encrypted files, online account credentials, personal photos, or instructions for physical assets like vehicles or property. Each inheritance specifies conditions for release (e.g., "30 days after I stop checking in").

What makes this fundamentally different from password managers or traditional estate planning?

The architectural time-lock* ensures beneficiaries receive all encrypted materials from day one, yet iOS platform security makes decryption impossible until blockchain-verified conditions are met. No company holds your keys. No institution needs to stay in business.

Smart contracts on Ethereum or Arbitrum automatically verify conditions (through your check-ins or optional human verifiers) and authorize access when appropriate. Everything operates through public blockchain infrastructure—transparent, verifiable, and permanent.

In practice:

Create inheritances directly from your phone (no lawyers needed for digital assets)
Update or revoke inheritances anytime with a few taps
Confirm your wellbeing via simple check-ins (<10 seconds)
Optional: designate human verifiers for additional protection

Once set up, your inheritances operate autonomously through public blockchain—no company dependency, no subscription required for execution.

This is inheritance reimagined: programmable, transparent, and cryptographically enforced—without trusting intermediaries.

*Patent Pending

Yes, fundamentally different. Here's why:

vs. Traditional Will:

A will states your intentions but requires human execution (notary, executor, probate court). Inheritor replaces this layer with a smart contract—your instructions execute automatically through blockchain when conditions are verified. No human intermediary controls the process.

vs. Password Manager:

Services like LastPass store passwords for your active use and may offer "emergency access" features.

But they're centralized services requiring:

Company to stay in business for decades
Trust that they won't get breached or shut down

Inheritor operates through public blockchain infrastructure that no single company controls. Once set up, your inheritance executes automatically regardless of whether any specific company survives.

vs. Multi-sig Wallet:

Multi-sig requires human coordination—multiple living keyholders must cooperate to authorize actions. This creates risk: disputes, coercion, unavailability of signatories. It's "human-trust-bound."

Inheritor requires no human coordination. Smart contracts verify conditions automatically (via your check-ins or optional verifiers). Beneficiaries don't coordinate with anyone—blockchain state determines access.

vs. Online Vaults/Storage:

Services like safety deposit boxes or cloud storage depend on:
Beneficiaries knowing where things are stored
Ability to prove authorization (often requires death certificates, probate)

Inheritor's architectural difference:

Beneficiaries receive all encrypted materials from day one—stored permanently on blockchain infrastructure (can't be lost, destroyed, or depend on a company surviving). Yet premature access is architecturally impossible: iOS platform security prevents key extraction until smart contract conditions are verified.

The breakthrough isn't just "secure storage"—it's conditional access without trusted intermediaries.

Your inheritance operates through public blockchain that anyone can verify and no one can shut down.

*Patent Pending

Inheritor implements On-Chain Digital Inheritance through a combination of blockchain smart contracts, decentralized storage, and iOS platform security.

Here's the architecture:

1. Storage Layer (Arweave):

Your encrypted inheritances—whether cryptocurrency keys, files, or documents—are stored permanently on Arweave, a decentralized storage network. Everything is encrypted using quantum-safe cryptography (X-Wing on iOS 26+). These encrypted materials are publicly accessible but useless without the decryption keys.

2. Smart Contract Layer (Ethereum/Arbitrum):

A smart contract on your chosen blockchain manages the state of each inheritance:

Designated: Inheritance exists, not yet claimable
Claimable: Conditions met, beneficiary can claim
Claimed: Beneficiary has accessed the inheritance

The smart contract doesn't hold your encrypted data—it just tracks and enforces conditions.

3. Condition Verification:

You confirm your wellbeing through periodic check-ins (takes <10 seconds). If check-ins stop:

Grace period begins
Optional verifiers (if designated) assess your status
When grace period expires, smart contract updates state to "Claimable"

4. The Architectural Time-Lock (Patent Pending):*

Here's the breakthrough: beneficiaries receive all cryptographic materials from day one—both blockchain keys and quantum-safe decryption keys—yet premature access is architecturally impossible.

How? The Inheritor app acts as gatekeeper, verifying smart contract state before authorizing any decryption operation. On iOS, platform security prevents extracting raw key material—keys exist on-device and sync via iCloud Keychain, but no API permits exporting them.

5. Access and Resilience:

iOS path: Full architectural time-lock using iOS 26+ platform security
Portable path: Exportable keys with conditional release service (ensures access even if iOS becomes unavailable)

The result: Your inheritance executes automatically when conditions are met, operates through public infrastructure (no company dependency), and provides cryptographic certainty that only authorized beneficiaries access materials at the right time.

For more details, see the white-paper on this site.

Inheritor uses a dead man's switch mechanism combined with smart contract verification to determine when conditions are met.

How it works:

1. Regular Check-Ins:

At intervals you choose (weekly, monthly, etc.), you confirm your wellbeing through the app—a simple button press taking less than 10 seconds. This check-in updates the smart contract on the blockchain.

2. Grace Period:

If you miss check-ins, a grace period begins (configurable by you—30 days, 60 days, etc.). This protects against false alarms: you might be traveling, sick, or simply busy. Multiple missed check-ins during this period don't immediately trigger release.

3. Automatic State Transition:

When the grace period expires without check-ins, the smart contract automatically updates your inheritance state from "Designated" to "Claimable," authorizing beneficiary access.

Optional: Human Verification Layer (premium version only)

For additional protection against accidental expiration, you can designate verifiers—trusted individuals who assess your condition if check-ins stop.

How verifiers work:

When your grace period expires, verifiers are prompted to confirm your status
They assess: Are you truly incapacitated, or just traveling/ill/unavailable?
If they confirm incapacitation, the smart contract updates state to claimable
Important: Verifiers never hold keys or control your assets—they only attest to conditions. The smart contract enforces all state transitions.

This dual-layer approach (automated check-ins + optional human oversight) prevents both premature claiming (if you're just unavailable) and indefinite delay (no human gatekeeper required).

The result: Your beneficiaries receive access automatically when appropriate, without depending on any institution to verify death certificates or navigate probate.

Yes, with important distinctions based on asset type.

The Legal Framework:

Inheritor aligns with established digital signature and blockchain recognition frameworks including eIDAS (EU) and ESIGN/UETA (US), which recognize:

Digital signatures as legally binding
Blockchain records as tamper-proof evidence
Cryptographic proof of authorship and acceptance

How Inheritor Establishes Legal Validity:

Each inheritance creates verifiable proof that:

The testator (cryptographically authenticated) created the inheritance
The designated beneficiary (uniquely identified) accepted the conditional right
The transfer instructions remain unaltered (blockchain immutability)
Conditions were met before access was authorized (smart contract verification)

This combines cryptographic certainty with legal enforceability.

Three Asset Categories:

Digital Assets (Access = Ownership)

For cryptocurrency, encrypted files, NFTs, domains, and online accounts, possession of credentials IS ownership.

Legal validity: Transfer is immediate and cryptographically provable. No legal intermediary needed—the blockchain record IS the proof of transfer.

Registry-Bound Assets (Legal Documentation Required)

For real estate, titled vehicles, and regulated securities, law requires formal transfer procedures.

Inheritor's role: Securely releases pre-signed deeds, notarized documents, or transfer instructions to beneficiaries when conditions are met. Beneficiaries then complete legal registration with appropriate authorities.

Legal validity: The documents themselves must comply with local law (lawyer drafts), Inheritor ensures secure, conditional delivery.

Institution-Mediated Assets (Without Formal Deed Requirements)

For online bank accounts, social media profiles, content channels, digital subscriptions, and family keepsakes—assets where institutional intermediaries exist but formal legal deeds are not required.

Inheritor's role: Releases documented intentions and access credentials. Beneficiaries use these to claim assets through existing institutional channels.

Legal validity: Demonstrates clear testamentary intent with cryptographic proof of authenticity. Institutions may accept these as sufficient evidence of inheritance rights without requiring formal probate.

What Makes This Different:

Traditional wills state intentions but require human execution (probate, executors, notaries). Inheritor uses smart contracts to automate the executor role where possible, while integrating with legal processes where required.

The architectural time-lock* mechanism ensures:

Beneficiaries can't access materials prematurely (even with possession)
No trusted intermediary controls the inheritance
Transfer executes automatically when blockchain-verified conditions are met

Legal Recognition:

Digital inheritance through blockchain is increasingly recognized globally, just as cryptocurrency evolved from experimental to legally acknowledged asset class. As with any testamentary instrument, specific inheritances may be challenged—but the cryptographic proof Inheritor provides (authorship, authenticity, unaltered content) strengthens rather than weakens legal standing.

Importantly, Inheritor doesn't replace legal counsel—it complements it where required. Lawyers draft documents ensuring local compliance; Inheritor ensures incorruptible delivery.
