What Happens to Your Cryptocurrency When You Die?
Last verified: 16 August 2026.
Of everything in your digital legacy, cryptocurrency is the only category that can genuinely cease to exist the moment you do.
A locked photo library can eventually be prised open. A frozen social account can be memorialised. An email archive can, with enough documentation and patience, sometimes be released. But a self-custodied crypto wallet with no recoverable key is not locked — it's gone, in the same way a sunk ship is gone. Nobody is withholding it. There is simply no longer a route to it, and there never will be again.
Estimates of how much Bitcoin has been permanently lost this way run into the millions of coins. A meaningful share of that is inheritance: people who died holding keys nobody else could find.
Two completely different situations
Everything about crypto inheritance depends on which of these you're in, and many people are in both without having thought about it.
Held on an exchange (custodial). Coinbase, Kraken, Binance and the rest hold the keys on your behalf. There's a company to contact, a process to follow, and — crucially — a real prospect of recovery.
Held in your own wallet (self-custody). A hardware wallet, a software wallet, a seed phrase written on paper. There is no company, no support line, no password reset, no appeal. The key is the asset. If your family can't reach the key, they can't reach anything.
The exchange problem: no beneficiary designation
Here's what surprises people who assume crypto exchanges work like banks or brokerages: they generally don't let you name a beneficiary.
Kraken states plainly that it doesn't currently offer the option to add a beneficiary to an account, and instead runs a documentary claims process — a death certificate (not one issued by a funeral home) plus documentation confirming your appointment as legal representative of the estate, such as probate or letters of administration. Coinbase likewise doesn't support naming a beneficiary on individual accounts, and routes inheritance through estate documents and the probate process.
Some exchanges have begun introducing nominee-style arrangements for certain cases, but these don't replace succession law, require documentary verification and identity checks, and take weeks to months.
The practical translation: your family will need legal authority over your estate before an exchange will speak to them substantively. That process takes months in a straightforward case and considerably longer in a complicated one — during which the assets sit untouched and unmanaged.
The trap inside the exchange problem
Even where an account is recoverable in principle, one detail sinks families more often than the paperwork does: two-factor authentication.
Most people set up 2FA on an authenticator app on their phone and never save the backup codes. When the person dies, that phone — wiped, locked or long since replaced — was the only thing standing between the account and the outside world. Knowing the password achieves nothing.
If you hold crypto anywhere, saving your 2FA recovery codes somewhere your executor can reach is one of the highest-value ten-minute tasks available to you.
Self-custody: the part no process can fix
If you hold your own keys, no amount of legal documentation helps. A court order cannot compel a blockchain. Your executor cannot subpoena mathematics.
Write your will. A guided will adapted to the rules where you live, with clear signing instructions.
What your family needs is the seed phrase or private key, and they need to be able to find it and understand what to do with it. That creates the central tension of crypto inheritance, and it's worth stating honestly:
Anything that makes your keys easy for your family to find also makes them easier for someone else to find.
That's the whole problem. Security and inheritability pull in opposite directions, and there's no arrangement that maximises both. What responsible planning looks like is choosing a deliberate point on that spectrum rather than defaulting to "my keys are extremely safe and completely unfindable."
Do not put a seed phrase in your will
This deserves its own heading because the instinct is so natural and the consequence so severe.
In many jurisdictions a will becomes part of the public probate record. A seed phrase written into a will can therefore become a public document — and a seed phrase that has been seen by anyone at all is no longer a seed phrase, it's a withdrawal instruction available to whoever read it. There have been cases of exactly this.
What a will can safely do is point: state that crypto assets exist, name where the instructions are kept and who should be involved, without reproducing the keys themselves. Getting that separation right in your own jurisdiction is worth proper advice — this is one of the places where a qualified professional earns their fee.
What actually works, in general terms
Without prescribing a specific setup — the right answer depends on how much is at stake, who your heirs are and how technical they are — the planning principles are consistent:
Make an inventory. Which exchanges, which wallets, roughly what's held where. Not the keys — the existence. Your family can't recover what they don't know exists, and crypto leaves no monthly statement in the post.
Save your 2FA recovery codes somewhere your executor can reach.
Separate the knowledge from the keys. Someone should know that crypto exists and where the instructions live, without that person necessarily holding the keys themselves.
Consider who's on the receiving end. An executor who has never used a wallet cannot be handed a seed phrase and expected to manage it. Either write instructions detailed enough for a complete beginner, or name someone technically capable alongside them.
Stress-test it. The only question that matters: if I died tomorrow, could my family actually reach this — and would they know it existed at all? If you can't answer yes to both, the plan isn't finished.
Revisit it. Holdings move, exchanges close, hardware wallets get replaced. A plan written three years ago may point at nothing.
The wider point
Crypto is the extreme case, but the underlying failure is the same one that runs through everything in your digital legacy: assets your family cannot reach are, in practice, assets they don't have.
It is the same gap that decides who can actually reach your photographs — ownership on paper is not the same as access in practice.
The difference is that with photographs there's usually a slow, painful route back. With self-custodied crypto there isn't one at all — which is why it's the one part of this worth doing properly this month rather than eventually.
