How to Securely Bequeath Crypto Assets Using Seed and Passphrases in a Will & Trust

As cryptocurrency becomes a more significant part of personal wealth, ensuring that these digital assets are properly and securely passed down to future generations has become increasingly important. Traditional inheritance methods may not fully account for the decentralized and secure nature of crypto. By dividing seed phrases and using unique passphrases for each beneficiary, you can create a more secure and reliable system that keeps both the Executor and beneficiaries accountable.

In this blog, we will walk through the process of securely distributing crypto assets through a will and trust using seed phrases and passphrases. This method ensures that access to your crypto is not centralized in one person’s hands, protecting both the Executor and your benefactors.

Why This Method Works

The main goal of using both seed phrases and passphrases is to add layers of security and trust to your crypto inheritance process. Here’s how:

The seed phrase: The seed phrase is the master key to all wallets. Anyone with the seed phrase can access your crypto.

The passphrase: A unique passphrase can be added to create distinct wallets tied to the same seed phrase. You can create an infinite number of passphrases tied back to a single seed phrase.  Each passphrase corresponds to a different wallet, protecting beneficiaries from accessing each other’s assets.

In this setup, you (the benefactor) have access to both the seed and passphrases during your lifetime. After your passing, a trusted Executor provides the seed phrase to your beneficiaries, while each beneficiary uses their unique passphrase to unlock only their portion of the inheritance.

This approach not only ensures privacy and security for each beneficiary but also holds the Executor accountable, as they cannot act alone without each individual’s passphrase.

How to Execute This Plan in 5 Steps

Here is a step-by-step guide to implementing this method in your will and trust:

1. Create a Cold Wallet with a Seed Phrase
Start by buying an open source hardware wallet (or multiple wallets) where your crypto assets will be stored (i.e. Trezor, GRID, BitBox02). This wallet will generate a seed phrase, typically a 12 or 24-word recovery phrase, that acts as the master key to access all funds.

- Store this seed phrase securely—ideally in a safe or using a secure, offline method. Use a solution like Black Seed Ink to protect the seed phrase from fire, water and corrosion damage. 
- Make sure the seed phrase is not shared with anyone during your lifetime.

2. Generate Unique Passphrases for Each Beneficiary
Once you have your wallet, create separate wallets using the same seed phrase but different passphrases for each beneficiary. These unique passphrases act as keys that unlock only their designated portion of the crypto inheritance.

- Document each passphrase carefully, as it will be needed by each beneficiary to access their share.

- Use Black Seed Ink's passphrase wallets to protect against fire, corrosion and water damage.  Store these passphrases securely and SEPARATELY from the seed phrase.

Note: There maybe other manufactures, however to date, Black Seed Ink is the only cold storage crypto solution that offers both seed phrase and passphrase wallets.

3. Appoint a Trusted Executor
Choose an Executor whom you trust to oversee your will and distribute your assets after your passing. The Executor will be responsible for distributing the seed phrase to your beneficiaries but will not have access to the individual passphrases.

- The Executor should be informed about the process and understand their role in distributing the seed phrase after your passing.

4. Detail the Plan in Your Will & Trust
Include specific instructions in your will that explain the distribution of your crypto assets using the seed and passphrases method. This should clearly outline:

- The role of the Executor in distributing the seed phrase to each beneficiary.
- Instructions for each beneficiary to use their unique passphrase in combination with the seed phrase to access their portion of the inheritance.
- A secure method for the Executor to provide the seed phrase to all beneficiaries after your passing.

Consult a legal professional who is familiar with crypto inheritance to ensure that your will is properly structured.

5. After Death: The Executor Provides the Seed Phrase
After your passing, the Executor's role is to deliver the seed phrase to each of the beneficiaries. However, since the seed phrase alone is insufficient to access the funds (due to the unique passphrases), each beneficiary must also use their passphrase to unlock their share.

- This ensures the Executor cannot access the assets independently, and each beneficiary can only access their designated portion of the crypto.

By splitting the access between the Executor and the beneficiaries, you create a system of checks and balances that protects the integrity of your crypto assets.

Benefits of This Method

Increased Security: By separating access between a seed phrase and unique passphrases, no single party holds the keys to your entire estate. The system is designed to prevent fraud or mismanagement.

Privacy for Beneficiaries: Each beneficiary has access only to their portion of the assets, ensuring their privacy and preventing others from seeing the entire estate.

Trust and Accountability: The Executor must collaborate with the beneficiaries to access the funds, creating a layer of accountability that traditional inheritance methods lack.

Final Thoughts

The seed phrase and passphrase approach offers a secure, trust-based solution for crypto inheritance. It ensures that both your Executor and your beneficiaries work together to unlock and distribute the assets fairly, without the risk of a single individual mismanaging your estate. By following these five steps and consulting with a legal professional familiar with cryptocurrency, you can create a secure and reliable way to pass down your digital wealth.
