What happens to crypto when someone dies without the keys?

If the crypto sat in self-custody, a hardware or software wallet, and nobody has the seed phrase, it is gone. Not locked, gone: no company, court, or recovery service can recreate a missing private key. If it sat on an exchange like Coinbase, the executor can recover it with a death certificate and probate papers. The first job is finding out which of the two you are dealing with.

• Roughly 20% of all Bitcoin appears lost or stranded in inaccessible wallets, per a Chainalysis estimate (The New York Times, 2021)
• Exchange-held crypto: recoverable by the estate with a death certificate and probate documents
• Self-custody crypto without the seed phrase: unrecoverable, by design

Why is self-custody crypto without the keys truly gone?

Because there is no company behind it. A self-custody wallet is controlled by a private key, usually backed up as a seed phrase of 12 or 24 words, and the math that makes crypto secure against thieves makes it exactly as secure against heirs. Nobody can reset it. There is no support line, no deceased-customer form, and no judge with jurisdiction over a mathematical function. A court can rule that the coins belong to the estate, and the coins will sit at their address, visible on the blockchain, untouchable forever.

The scale of this is not a rounding error. Chainalysis, a blockchain-analytics firm, estimated that roughly 20 percent of all Bitcoin sits in wallets that appear lost or stranded, a figure The New York Times put at about 140 billion dollars when it reported the estimate in January 2021. A meaningful share of that is inheritance that never happened.

How do you tell self-custody from an exchange account?

This is the executor's first real task, and it is detective work, not paperwork. Look for these:

1. Hardware wallets: small USB-like devices from Ledger, Trezor, or similar, often in a desk drawer or safe. Finding one means self-custody; now the search is for its seed phrase.
2. Seed phrase backups: a numbered list of 12 or 24 plain English words, handwritten on paper or stamped into a metal plate. This is the key itself. Secure it like cash and share it with no one.
3. Exchange traces: emails from Coinbase, Kraken, or Binance, an app on the phone, or statement entries showing transfers to an exchange. These mean recoverable funds.
4. Wallet apps on the phone or computer, which may hold funds locally or just watch an exchange account; the app's name plus the email trail usually settles which.

Money often lives in both places at once. Treat every trace as its own lead until you have either a seed phrase or an exchange name in hand.

What can the executor actually recover?

Everything on an exchange, with patience. Exchanges are companies with compliance teams, and each runs a deceased-customer process: the executor submits the death certificate, government ID, and the probate papers naming them, and the exchange transfers or liquidates the funds to the estate. Our Coinbase page walks that exact packet. Expect 30 to 90 days, not miracles, and expect a court document to be required in every case.

For self-custody, recovery means finding the seed phrase the person left, so search before you mourn the money: safes, safe-deposit boxes, filing cabinets, book margins, password managers, and anywhere someone hides a thing they must never lose. If a wallet file exists but the password is lost, a professional recovery firm has a real shot at a weak password. If nothing survives, it is over, and the kindest thing this page can do is say so plainly.

The whole gap between the two outcomes was one sheet of paper. Where the rest of the estate is concerned, our digital executor's checklist keeps the remaining accounts from going the same way.
