Premium Version

Before you can make use of the premium version, Inheritor will activate it by deploying a specialized smart-contract on the Ethereum blockchain. Just keep the app open until this process is completed. The Ethereum logo in the toolbar will blink softly to indicate premium activation is in progress.

When the activation is completed, Inheritor shows a message. You are now ready to use all premium features described in this document.

One Subscription for Your Entire Family

Your Inheritor Premium subscription can be shared with up to five family members through Apple's Family Sharing feature. This means that a single subscription provides everyone in your family with access to all premium features, allowing them to create their own secure Digital Wills.

This makes securing your entire family's digital legacy both simple and highly cost-effective. While premium features on the Ethereum network (like using a Verifier) require Credits for each user's transactions, the base subscription cost is covered for everyone. This helps offset the overall cost of ensuring each family member can access the highest level of security for their most important inheritances.

Credits are used to maintain your Digital Will on the Ethereum blockchain. Where transactions on Arbitrum are fast and included in the subscription fee, Ethereum transactions are much slower while the transaction fee is higher and much more fluctuating.

This is the price to pay for the benefits the Ethereum network offers (see next section). Some Inheritor features (like verifiers) are only possible on Ethereum.

Purchasing Credits

You can purchase credits as an in-app purchase when you click the Ethereum symbol in the toolbar. Just follow the in-app instructions.

Spending Credits

Each time you interact with the smart-contract on Ethereum, Inheritor will inform you how many credits the operation takes. Normally this should be not more than 1 credit per operation. However, when the network is busy the amount of credits required can be considerably higher.

You always have the option to perform the operation another time when the amount of credits required is lower.

The Analogy: A City's Bedrock (Ethereum) vs. its Efficient Suburbs (Arbitrum)

Ethereum Mainnet is like Manhattan's bedrock foundation. It is the original, time-tested, and globally recognized digital territory. The laws are written here, the deepest vaults are located here, and it's protected by a global, decentralized consensus. Building here is resource-intensive (requiring Credits), but what you build is meant to last for generations.

Arbitrum is like a vibrant, modern suburb built for today's needs. It's incredibly fast, convenient, and cost-effective—so much so that all operations are covered by your subscription. It relies on the city's bedrock for its ultimate security but prioritizes everyday efficiency.

You choose where to build based on the purpose and permanence of your inheritance.

Why Choose Arbitrum (The Suburb)

All transactions on Arbitrum are fast, efficient, and their costs are covered by your flat-rate subscription fee. This makes it the perfect choice for standard inheritances where speed and a predictable, worry-free cost model are your priorities. The user experience is seamless and instant.

Why Spend Credits on Ethereum (The Bedrock)

When you are dealing with a legacy intended to last for decades, the considerations change from "what's easy now" to "what will endure." This is why you spend Credits to anchor an inheritance to Ethereum.

Ultimate Security & Decentralization

Ethereum is not just secure; it's the global gold standard of decentralization. It is validated by thousands of independent operators across the globe. This means no single company, group, or entity controls it. Your inheritance on Ethereum exists on a network designed for maximum resilience against any single point of failure.

Censorship Resistance

This is a critical factor for a legacy. Because of its vast decentralization, no single government, corporation, or individual can easily block, alter, or reverse your inheritance. It exists independently of any one party's influence. While Arbitrum is highly secure, its architecture has fewer (though still decentralized) operators, making Ethereum the superior choice for absolute censorship resistance.

Future Resilience & Longevity

Ethereum has the longest track record, the largest developer community, and a publicly committed roadmap focused on ensuring it lasts for centuries. More importantly, the long-term vision for Ethereum is to integrate technologies that will eventually give it the speed and low costs of today's L2s. By placing your most important inheritances on Ethereum now, you are not just choosing security for today; you are planting your flag in the most future-proof digital territory that exists. It is the definitive choice for anyone taking the passing of their legacy seriously.

Overview

The Inheritor app's verification system provides an additional layer of security and confirmation before digital inheritances become claimable. This system involves three types of users working together to ensure inheritances are only claimed when appropriate.

The Three User Types

1. Testator: The person creating digital inheritances and potentially setting up verifiers.
2. Verifier: A beneficiary who can confirm whether a testator is incapacitated.
3. Beneficiary: Persons who have 0, 1 or more designated inheritances.

How the System Works

When a testator misses their regular check-ins:

• Without a verifier: Inheritances become claimable automatically after the grace period.
• With a verifier: The verifier must first verify the testator's condition before inheritances become claimable.

This system prevents premature claiming while ensuring legitimate inheritances can still be accessed when needed.

For Testators: Setting Up Verifiers

What is a Verifier?

A verifier is a trusted person (and one of your beneficiaries) who acts as an additional safeguard in the execution of your digital will. If you miss your regular check-ins, the verifier can confirm whether you are truly incapacitated before your inheritances become claimable by beneficiaries.

Why Use a Verifier?

• Benefits: Prevents accidental or premature inheritance claims, adds human judgment to the automated system, provides peace of mind, and protects against technical failures.
• Considerations: Requires a premium subscription, only works with Ethereum inheritances, verifier must be someone you trust, and can delay legitimate claims if the verifier is unavailable.

Requirements to Set Up a Verifier

1. Premium Subscription: Verifier functionality requires an active premium subscription.
2. Ethereum Inheritance: The person you want to make a verifier must have at least one designated Ethereum inheritance from you.
3. Trusted Relationship: Choose someone who is reliable and understands their responsibility.

How to Set Up a Verifier

1. Step 1: Ensure Prerequisites - Verify you have a premium subscription and your chosen verifier has an Ethereum inheritance from you.
2. Step 2: Navigate to Beneficiaries - Open the app, go to the "Beneficiaries" tab, and find the beneficiary.
3. Step 3: Make Them a Verifier - Long-press on the beneficiary card, select "Make Verifier," confirm, and wait for the transaction to complete.
4. Step 4: Verify Setup - Look for a checkmark (✓) next to the beneficiary's name.

Managing Your Verifier

To remove a verifier, long-press their card and select "Remove Verifier."

• You can only have one verifier at a time.
• Removing a verifier means inheritances will become claimable automatically after grace periods.

For Verifiers: Understanding Your Role

What Does Being a Verifier Mean?

As a verifier, you have been entrusted with an important responsibility. When a testator misses their check-ins, you may be asked to verify whether they are incapacitated. You will see a checkmark (✓) in the claim tab for any testator who has assigned you this role.

Your Responsibilities

1. Monitor for verification requests.
2. Respond promptly.
3. Verify truthfully.
4. Maintain confidentiality.

How to Identify When Verification is Needed

In the "Claim" tab, press "Verify Claimability" for any card with a checkmark (✓). If the message "Your Verification is required. Please verify the wellbeing of Testator!" appears, you must check on the testator. If they are fine, ask them to check-in. If not, you can proceed with verification.

How to Submit Verification

1. Tap the "Submit Verification" button.
2. Read the confirmation message carefully: "By submitting your verification, you confirm the Testator is irrevocably incapacitated."
3. Only proceed if you have confirmed this is the case.
4. Tap "Confirm" to submit your verification to the blockchain.

Once you submit verification, the action is recorded on the blockchain and cannot be reversed. The inheritance then becomes claimable for all beneficiaries.

Understanding Verification Period

Verification Period: This is the time after a testator misses a check-in before a verifier is asked to confirm their condition. The verification period ensures that beneficiaries aren't alarmed unnecessarily after a single missed check-in and is independent of the 'grace period' for each inheritance.

The Inheritor app's verification system provides a balanced approach to digital inheritance, combining automated convenience with human oversight. By understanding your role and responsibilities, you can help ensure that digital inheritances are handled appropriately and in accordance with the testator's wishes.

Remember that this system is designed to supplement, not replace, traditional estate planning. For significant assets or complex situations, always consult with qualified legal professionals.
