How to Plan a Crypto Inheritance: Wills, Metal Backups and the Gear Your Heirs Will Need

Self-custody solves one problem and creates another. When you hold your own keys, no exchange can freeze your funds, but no exchange can hand them to your family if something happens to you either. Crypto with no recovery plan can be lost for good. This guide walks through a practical inheritance setup and the physical gear that makes it work.

A note before we start: this is general education, not legal advice. Inheritance law varies by country and state, so have an estate attorney review your final plan.

The Core Rule: Don’t Put Your Seed Phrase in Your Will

A will often becomes a public record during probate, and it’s read by people who may not need your keys. Most crypto estate planning advice suggests splitting the plan into two parts:

• The legal layer: your will or trust says who inherits your crypto and names someone to manage the process.
• The access layer: a separate, secured “letter of instruction” plus physical backups explain how to reach the funds, stored where only the right people can get to them at the right time.

The best single resource on this split is Cryptoasset Inheritance Planning: A Simple Guide for Owners by attorney Pamela Morgan. It’s short, non-technical, and includes checklists and worksheets you can fill in. If you buy only one thing from this list, make it this book.

Step 1: Make an Inventory

Your heirs can’t recover what they don’t know exists. Write down every place you hold crypto: exchange accounts, hardware wallets, software wallets, staking positions and any DeFi protocols. For each one, note what it is and where its backup lives, but not the secret itself. Update it at least once a year.

Step 2: Use a Hardware Wallet Your Heirs Can Actually Operate

Inheritance plans fail when the person inheriting can’t figure out the device. Pick a mainstream hardware wallet with good documentation and a large user base, so your executor can find help. Two common choices:

• Ledger Nano X: Bluetooth plus USB, a companion mobile app, and broad coin support.
• Trezor Safe 3: open-source firmware and a simple interface for heirs who aren’t technical.

We compare these in more depth in our Ledger vs. Trezor guide. Write the device’s PIN-recovery steps into your letter of instruction. The seed phrase, not the device, is what actually holds the funds.

Step 3: Back Up the Seed Phrase on Metal

Paper burns, floods and fades. A stainless steel backup survives house fires that would destroy paper and most electronics. Popular options include:

• Cryptosteel Capsule: a sealed tube of letter tiles that’s compact and easy to hide.
• Billfodl: a stainless steel plate with sliding letter tiles that holds a full 24-word phrase.

Our metal seed phrase backup guide covers how to stamp or assemble these correctly.

Step 4: Avoid a Single Point of Failure

One seed phrase in one drawer is a single point of failure: anyone who finds it can take everything. For larger holdings, a multisignature setup lets you spread keys across locations and people, so no single lost or stolen backup is fatal. A common pattern is 2-of-3: you hold two keys, and a trusted person or professional holds the third. We walk through it in our 2-of-3 Bitcoin multisig guide. Multisig adds complexity, so it’s only worth it if your instructions explain clearly how heirs reassemble the quorum.

Step 5: Store Everything Securely and Make It Tamper-Evident

Physical storage needs to stop both disasters and snooping:

• SentrySafe fire- and water-resistant safe: a home safe for your hardware wallet, letter of instruction and one backup. See our fireproof safe roundup for ratings to look for.
• Tamper-evident security bags: seal backups inside numbered bags and log the serial numbers. If a bag has been opened, you’ll know.
• Fireproof document bag: a cheap extra layer for the paper letter of instruction.

Keep backups in separate locations, for example one at home and one in a safe deposit box or with your attorney, so a single fire or burglary can’t wipe out every copy.

Step 6: Write the Letter of Instruction

This document is for a stressed, grieving, possibly non-technical person. Write it in plain language and include:

• Your inventory and where each backup is stored
• Step-by-step recovery instructions for each wallet type
• Who to contact for technical help, and a warning that legitimate helpers never need the seed phrase sent to them
• A reminder to watch for scams, since people who just inherited something are frequent targets

Step 7: Do a Dry Run

Test the plan with a small amount. Have your executor, or a trusted person acting as a stand-in, follow your instructions on a spare device and recover a test wallet. Any step that confuses them is a step to rewrite. Review the plan whenever you add a wallet, change devices or have a major life event.

The Bottom Line

A solid crypto inheritance plan comes down to a will that names heirs, a separate letter that explains access, durable metal backups stored in more than one place, and a dry run to prove it works. The gear costs far less than the value it protects, and an afternoon of planning can save your family a lot of trouble later.
