It is a grim question, but an important one that almost no one plans for: if something happened to you tomorrow, could your family actually access your crypto? For self-custodied coins, the uncomfortable answer is usually no — and an enormous amount of crypto is already lost this way forever.
Why crypto is uniquely easy to lose
With a bank account, your family can present a death certificate and the bank will release the funds. There is an institution with a record of your account and a legal process to follow.
Self-custodied crypto has no institution and no recovery process. Whoever holds the private keys controls the coins. If those keys — or the seed phrase that backs them up — die with you, the coins are not "frozen" awaiting a claim. They are simply unreachable, forever. No court order can recover them.
This is the flip side of "be your own bank": you also inherit the bank's responsibility for succession planning.
The core tension
Estate planning for crypto has one hard tension at its centre:
- If you make your keys too easy for heirs to find, you make them easy for a thief to find while you are alive.
- If you make them too hard to find, they may be lost when your heirs actually need them.
A good plan threads this needle: accessible to the right people at the right time, useless to anyone else before then.
A practical approach
You do not need to be wealthy to do this sensibly:
- Write down what exists, not the secrets. Leave a clear note listing that crypto exists, roughly where (which wallets or exchanges), and who to contact for help — without writing the actual seed phrase in the same place.
- Secure the seed phrase separately. Store the recovery phrase somewhere durable and private — a safe, a bank deposit box — and make sure a trusted person knows it exists and how to reach it, even if they cannot see it yet.
- Consider a multi-key setup for larger holdings. Multi-signature wallets can require, say, two of three keys, letting you distribute control so no single lost or stolen key is fatal.
- Use exchange tools where they exist. Some regulated exchanges offer beneficiary or inheritance processes — easier for heirs, at the cost of not being self-custody.
- Write instructions for non-technical heirs. Assume the person inheriting has never used a wallet. Step-by-step plain-language instructions matter as much as the keys themselves.
Keep it current
A plan made once and forgotten is nearly as risky as no plan. Wallets change, exchanges close, and seed phrases get moved. Revisit your arrangement when your holdings or your tools change, and confirm the trusted people involved still know their role.
What not to do
Two tempting shortcuts cause real losses. The first is putting your seed phrase directly in your will. Wills can become public documents during probate, and they are seen by more people than you think — anyone who reads it could drain the wallet. Reference that the crypto exists and where the instructions are kept, but never write the actual phrase there. The second is relying on a single person's memory or one fragile copy of the keys. People forget, notes get thrown out, drives fail. Redundancy — more than one durable copy, stored separately — is what turns a plan from hopeful into reliable.
Takeaway
Self-custodied crypto disappears permanently if no one can reach your keys — there is no institution to claim it from. Plan ahead: document that the crypto exists, store the seed phrase securely and separately, tell a trusted person it exists, consider multi-signature for larger sums, and leave instructions a non-technical heir can follow. The freedom of self-custody includes the duty to plan for handing it on.
Self-custody means you are fully responsible for your keys, in life and after. No one can recover lost keys for you or your family.
