Somewhere tonight, a widow is sitting at a kitchen table with her late husband's laptop. She knows the money is real. She watched him check it every morning with his coffee. She knows roughly how much it was worth, because he told her once, half proud and half nervous. What she does not have is twelve to twenty-four ordinary words, written down somewhere in a particular order. Without them, the money is not hidden or frozen or tied up in court. It is just gone, and there's no customer service line to call.
The hard part is that he did everything right. He used a hardware wallet. He never kept his keys on an exchange. He turned down every phishing email and every stranger in his DMs. He built a fortress, and it worked. It kept everyone out, including the person he loved most.
The idea most crypto holders miss: thieves and heirs look the same to a wallet
All the security advice in crypto is aimed at one enemy: the attacker. Don't share your seed phrase. Don't store it digitally. Don't tell anyone how much you hold. Every rule makes it harder for a stranger to take your money.
But from the blockchain's point of view, a stranger and your daughter are the same thing. Both are someone who isn't you and wants to move the funds. Any barrier you put in front of a thief also sits in front of your heirs. Most people never think about the second case, because the second case requires them to imagine being dead.
With a bank account, the law fills the gap. An executor shows a death certificate and letters of administration, and the bank hands over control. Most U.S. states have also passed a version of the Revised Uniform Fiduciary Access to Digital Assets Act, which gives executors some legal authority over a person's digital accounts. But no court order can make a self-custody wallet give up its private key. The law can say your heir is entitled to the bitcoin. Only the key can actually move it.
This has already happened at a large scale. When Gerald Cotten, founder of the Canadian exchange QuadrigaCX, died suddenly in 2018, the exchange said it could not reach the cold wallets holding customer funds. Customers were reported to be owed around C$190 million. Later investigations found the story was messier than a lost password, but the first headline was the one that stuck: one man held the keys, and when he died, access died with him. Blockchain analysts have estimated for years that a meaningful share of all bitcoin ever mined is permanently unreachable. Some of it was lost to forgotten passwords and some to discarded hard drives. Some of it was simply outlived by its owner.
Why smart people build this trap
The people most likely to lock out their heirs are often the most competent holders, and psychology helps explain why.
The first factor is what researchers call the curse of knowledge. Economists Colin Camerer, George Loewenstein, and Martin Weber described it in 1989: once you know something, it becomes very hard to imagine not knowing it. You know which drawer holds the metal backup plate. You know the PIN is your childhood street plus a number only you would pick. You know the passphrase, the "25th word", sits in a password manager whose master password you never wrote down. Because it's obvious to you, you assume it would be obvious to anyone. It wouldn't be, and least of all to someone who is grieving.
The second is optimism bias, the well-documented tendency to underestimate how likely bad things are to happen to us personally. You'll set up inheritance access later, once your holdings settle down or the market calms or you pick the right tool. Later feels like a real date, but it isn't one.
The third is quieter: secrecy feels like virtue. In crypto culture, telling no one is treated as a sign of competence. So the thought of writing instructions for your spouse can feel like you're breaking your own security, even though what you're really doing is finishing it.
Under all three is something people rarely say out loud. Many crypto holders haven't told their partner how much they own. Sometimes that's because it's volatile and embarrassing. Sometimes it's because the partner thinks it's gambling. Sometimes it's just never come up. An inheritance plan forces that conversation, so the plan never gets made.
Design for a confused, grieving person, not just a hacker
The fix isn't weaker security. It's a second threat model sitting next to the first. Ask two questions about your setup:
- What would a stranger need to steal this?
- What would someone I love, on the worst week of their life and not technical, need to recover it?
A good plan makes the first answer very hard and the second answer possible. You get there with one principle: separate the map from the keys.
The map is everything that isn't secret enough to steal money with. It says what you own, which wallets and exchanges you use, what kind of hardware device you have, where the backups physically live, which people or professionals to call, and a plain-language explanation of what a seed phrase is. The map can be shared fairly widely. Your executor should have it, and a copy can sit with your other estate documents.
The keys are the seed phrases, passphrases, and PINs. They should never sit in the same place as the map, and never in a document that will become public.
That last point matters. Do not write your seed phrase into your will. A will that goes through probate generally becomes a public court record, and even before that, several people may handle it. Your will can name your crypto as an asset and point to a separate letter of instruction, but it shouldn't contain anything that could move funds.
After that, there are a few honest ways to handle the keys, depending on how much you hold and how technical your family is:
- A sealed backup in secure storage. A metal seed backup kept in a home safe or a safe deposit box, with the map explaining where it is and how to get to it. This is simple, and simple is easy to recover.
- Splitting trust. Some people keep the seed phrase in one place and the optional passphrase in another, held by a different trusted person, so no single document or person can drain the wallet.
- Multisignature wallets. A multisig setup, for example 2-of-3, needs several keys to move funds. You might hold two keys and a trusted person or a collaborative-custody service hold the third. It's more robust, but also more complex, and complexity is exactly what a grieving family struggles with. Only use it if your instructions really explain it.
No method is perfect. What matters is that you chose one on purpose, instead of letting the default, which is total loss, choose for you.
The test that tells you if it works
There's one test that matters, and almost nobody runs it. Ask the person most likely to inherit, or your executor, to read your map and explain back to you how they would get to the money. Don't hand over keys and don't move anything. Just walk through the steps.
You'll find gaps right away. They won't know what a "hardware wallet" looks like. They'll assume the Ledger app on your phone is the wallet itself. They won't know that typing a seed phrase into a website that asks for it is how you lose everything to a scam. Every confused question is a line your map needs to answer.
This is the curse of knowledge in practice. You can't see your own blind spots, but the person you're writing for can.
Your next moves
- Make a one-page crypto map tonight, with no secrets on it. List every exchange, wallet type, and device, plus roughly where each backup is physically stored. Write it so a smart non-technical person could follow it.
- Check whether your recovery depends on things only you know. If your seed backup requires a passphrase, a PIN, or a password manager login that is written down nowhere, fix that gap first. It's the most common way plans fail.
- Add one sentence to your estate documents. Ask your attorney to name digital assets in your will or trust and point to a separate letter of instruction, without putting any keys in it.
- Pick the one person and tell them it exists. You don't have to share amounts or keys yet. Just say: "If something happens to me, there's crypto, and here's where the instructions are." That one conversation does more for your heirs than any wallet setup.
- Run the walk-through within 30 days. Have that person explain the recovery back to you, and rewrite every step that confused them.
A map they can actually follow
This is the problem Heirloom was built for: keeping the map separate from the keys. It gives you one organized place to record what you own, where it lives, and who to call, so the people you leave behind get a clear trail instead of a locked laptop and a guess. Your seed phrases stay where they belong. Your family gets the directions. If you've been meaning to write it down "later," you can start the map at Heirloom this evening and finish the hard conversation while you're still here to have it.
