Cryptography & Keys

What is a Public Key?

A Public Key is used in Public-key cryptography (or asymmetric cryptography) which forms the base of all blockchain transactions. This key is 'public' so you can share it with anyone who might be a (potential) Beneficiary. Simply speaking, a public key is a key that can only close locks.

What is a Private Key?

A Private Key is used in Public-key cryptography (or asymmetric cryptography) which forms the base of all blockchain transactions. This key is 'private' so you should NEVER share it with anyone. Simply speaking, a private key is a key that can unlock locks which have been closed by a Public key.

What Encryption does Inheritor use? Can I safely pass on all my secrets (private keys, passwords, business documents) to my loved ones using Inheritor?

Yes, as long as you keep your Private key private. Please refer to the for technical details.

Beneficiaries

What is a Beneficiary?

A Beneficiary is any person named in your Digital Will. You can add potential Beneficiaries by scanning their Beneficiary code. Whenever you are ready to designate an Inheritance to a person, you can select any of the potential Beneficiaries.

What is a Beneficiary code?

In Inheritor, the Beneficiary code consists of the (uncompressed) public key + the name (moniker) of the beneficiary in hex-encoded format. As this code is very long, you can add new Beneficiaries easily by just scanning a QR code. The Beneficiary code is used by Inheritor to create a unique link between Testator and Beneficiary as together they form a public/private key pair.

Inheritance attributes

What is a Network?

In Inheritor, "network" refers to either the Ethereum (mainnet) blockchain or the Arbitrum (One) blockchain.

What is an Anonymous Inheritance?

You can designate an Inheritance to a Beneficiary anonymously. This means that the Beneficiary will not know or see from whom they have been designated an Inheritance.

What is a Grace Period?

The Grace Period determines the time between the last Check-in of the Testator and the moment the Inheritance becomes 'Claimable' by the Beneficiary.

What is a Check-in?

Check-ins are an implementation of a 'dead man switch' in Inheritor. By checking in regularly, the smart contract knows that you are OK. When you miss a check-in, the smart contract will assume something is wrong with you, and then will make the Inheritances available to the designated Beneficiaries in accordance with the Legacy Settings.

What are Legacy Settings?

Inheritor offers several settings that help determine if and when your Digital Will is executed.

An Inheritance has become 'Claimable'. What should I do?

Carefully read and follow the instructions in the Inheritor app. It is very important that you save the Digital Asset you Inherited before you set the status of your Inheritance to Claimed.

Verifiers

What is a Verifier?

A Verifier is any person who can 'verify' your wellbeing. You can assign any Beneficiary to become a Verifier. Normally these are close relatives.

Why should I add a Verifier?

Assigning a Verifier provides an extra level of protection to ensure your Digital Will is only executed when you have become irrevocably incapacitated. On top of the normal Check-in, a human being has to verify your wellbeing before the Digital Will is executed. Note also that Verifiers will not receive any Inheritances until they confirm the incapacitation of the Testator.

I am a Verifier. Inheritor asks me to verify the wellbeing of a family member. However, they are doing ok. What should I do?

Ask your family member (the Testator) to Check-in. Then all will be reset to normal.

I am a Verifier of a family member who passed away. What should I do?

You will see that your Inheritance has been marked with a checkmark to indicate that you are indeed a verifier. Just click 'verify claimability'. When the Testator has missed their check-in due to passing away, you will see a message. Next, click the 'Verification Required' button to confirm the death (or irrevocable incapacitation) of the Testator. After the Transaction succeeds, you and all other Beneficiaries will receive their Inheritance after its Grace Period has expired.

Technical Identifiers

What is an (Inheritance) ID?

The ID is a unique number that identifies each Inheritance.

What is 'Contract Address'?

The Contract Address is the 'address' where the smart contract containing your Digital Will lives on the blockchain.

What is 'Transaction Hash'?

This is a unique identifier of the Transaction that created a particular Inheritance in your Digital Will.

What is (Inheritance) 'State'?

In the lifecycle of an Inheritance, it can have different states. [Note: The original text didn't list the states]

What is EOA (Testator / Beneficiary)?

This means the Ethereum Original Address (of Testator). This is a unique number that identifies the Testator on the network. With Inheritor, you (as user) can adopt two roles: one as Testator, and one as Beneficiary of Inheritances. To create maximum security, the two roles are separated; hence, you (as user) will have been assigned an EOA for your role as Testator and for your role as Beneficiary.

What is 'Smart Account' (Testator / Beneficiary)?

A Smart Account is a smart contract wallet that follows the ERC-4337 specification. This protocol allows Inheritor to pay for Transactions on your behalf. Smart accounts are just smart contracts with specific tasks. These contracts are created when you first open Inheritor (on Arbitrum One), or when you upgrade to the Premium tier (on Ethereum) during 'Premium Activation'. With Inheritor, you (as user) can adopt two roles: one as Testator, and one as Beneficiary of Inheritances. To create maximum security, the two roles are separated; hence, you (as user) will have been assigned a Smart Account for your role as Testator and for your role as Beneficiary.

What is 'Arweave ID'?

This is a unique ID under which your Digital Asset is stored (encrypted) on the Arweave Blockchain (BlockWeave). You can verify the presence of your Digital Asset when you click the Arweave ID. Note that the Digital Asset is encrypted such that it can only be decrypted by the Beneficiary. Though the Digital Asset is on the 'public' blockchain (all blockchains and the data they store are publicly accessible), nobody except the Beneficiary can view its contents (see our White Paper).

Error Handling

Inheritor Shows "Initialization Error" during startup. What should I do?

This can happen in cases of very high traffic on the blockchain network. It indicates too many requests are being received by the network. You can simply quit the app and try again later.

Inheritor Shows an other error. What should I do?

Please just try whatever you were doing again. Blockchains are complex technologies, and unpredictable situations can occur. Make sure you have a good working Internet connection or restart the app. Contact support@inheritor.app when all options fail.
