Over $140 billion in Bitcoin is gone forever. Not stolen. Not hacked. Lost—because the people who owned it died without leaving their keys behind. Here's how to make sure that doesn't happen to your crypto.
Estimated value of Bitcoin permanently inaccessible due to lost keys and deceased holders with no succession plan. That number grows every year.
Chainalysis estimates that roughly 20% of all Bitcoin in existence is permanently lost. Death accounts for a significant slice. The mechanics are brutally simple: you die, nobody knows your seed phrase, and your holdings become unreachable digital rubble—no matter how much they're worth.
This isn't a niche edge case. It's happening right now, to real families, who discover too late that their loved one's crypto fortune is protected by one very effective security mechanism: death.
Traditional assets have a safety net. A bank can verify your identity, accept a death certificate, and release funds to an estate. A brokerage can do the same. The system—however slow—eventually works.
Crypto has no safety net. That's the point. And it's exactly why inheritance is so difficult.
Here's what your heir actually needs to access your crypto—and why each step is a potential dead end:
Stack these layers together and you have a system that's genuinely excellent at preventing unauthorized access—including authorized heirs. The crypto community built Fort Knox and forgot to leave a key with a lawyer.
When people think about this problem, they usually reach for one of these approaches. All of them are flawed.
| Approach | The Problem |
|---|---|
| Put it in your will | Wills are public records. Your seed phrase becomes a public document. Also, probate can take months—and lawyers can't manage private keys. |
| Safety deposit box | Static. What if you rotate keys, move wallets, or open new exchange accounts? You'd need to update the box constantly—and hope it's not sealed after you die. |
| Share the seed phrase now | Premature disclosure. Your heir now has full access while you're alive. One bad relationship, one moment of weakness, and your holdings are gone before you die. |
| Shamir's Secret Sharing | Technically elegant, practically catastrophic. You need to coordinate multiple keyholders, all of whom need to survive and cooperate. One death, one disappearance, and it fails. |
| Tell a lawyer | Lawyers don't understand private keys. Estate attorneys are not equipped to manage cryptographic material. They'll write it down wrong, lose it, or expose it. |
The real danger with static solutions: Crypto holdings change. Wallets get rotated. New exchanges get added. New assets accumulate. Any solution that requires manual updates will eventually fall out of sync—which means your heir gets outdated credentials for assets that no longer exist the way you documented them.
The fundamental problem isn't storage. It's timing. You need your heir to get access after you die, but not a moment before. No existing system handles this correctly—except a dead man's switch.
A dead man's switch is a time-based trigger. You check in regularly to prove you're alive. If you stop checking in, the system assumes something has happened—and automatically releases your vault contents to your designated heir.
This solves the timing problem cleanly:
The key insight: your heir doesn't need access now, they need access when you're gone. A dead man's switch provides exactly that—automated release, triggered by your absence.
PulseVault is built on this exact principle. Here's the full sequence:
The 30-day buffer after the initial miss is intentional. It catches false alarms: extended hospitalization, phone loss, extended travel without internet access. You get multiple escalating reminders across the escalation window. Only sustained, unexplained non-response triggers release.
Everything stored in PulseVault is AES-256 encrypted at rest. Your heir can't access anything until the trigger fires. Even PulseVault can't read your vault contents. The keys to decrypt are only released when the dead man's switch activates.
Pricing: $2.99/month. That's it. No tiers, no annual contracts, no per-asset fees.
Setting up takes about 10 minutes. Here's the exact process:
Sign up at pulsevault.polsia.app. Your vault is encrypted client-side before it reaches our servers. We never see the raw content.
For each wallet or exchange, create a vault entry. Include: the exchange name, account email, seed phrase or private key, hardware wallet PIN if applicable, and any additional passphrase (25th word). Use the Notes field for context your heir will need—e.g., "This is the Ledger in the fireproof box on the third shelf."
Don't just hand them credentials. Write instructions. Which wallet holds what. Which exchange is for trading vs. cold storage. What to do first when they receive the vault. A 200-word letter now prevents months of confusion later.
Enter their email address. When the dead man's switch triggers, they receive an encrypted package with your vault contents and your instructions. They don't need a PulseVault account in advance.
The default is 90 days. You'll receive an email prompt to check in. One click confirms you're alive and resets the clock. That's the entire maintenance burden: one click, four times a year.
Whenever you add a new wallet, rotate keys, or open a new exchange account—update your vault. The latest version is what your heir receives. This is the part static solutions get catastrophically wrong; PulseVault handles it naturally.
The largest recorded loss from a single individual's death was Gerald Cotten, the founder of QuadrigaCX, who died in 2018 holding the sole private keys to approximately $190 million CAD in customer funds. The money was never recovered.
That's an extreme case. But the mechanics are identical for ordinary holders. A person dies holding $40,000 in Bitcoin on a hardware wallet, with the seed phrase memorized and nowhere written down. The family hires a blockchain forensics firm. They spend $5,000. They find the wallet. They confirm the balance. They still can't access it.
The blockchain doesn't negotiate. There are no appeals. The coins sit there, fully visible, permanently unreachable, forever.
That outcome is avoidable. It costs $2.99 a month to avoid it.
10 minutes of setup. Four check-ins per year. Your heirs get everything when it matters.
