Created for Garrett G., who had the top-voted idea this week. This tutorial assumes you have some working knowledge of wallets, hardware (cold) wallets, and vaults. These are things worth look into—consult professionals before you make any big changes.
There are only two ways to lose your crypto.
Theft. And loss.
Every storage decision you make is a trade-off between them. Lock the keys down hard enough to stop a thief—you risk locking yourself out. Make recovery easy enough for your spouse—you've made it easy for someone else, too.
Most people pick one threat and pretend the other doesn't exist.
That's how fortunes vanish.
Quadriga. CEO died in India. Took the cold wallet keys with him. 115,000 customers. $215M gone.
Stefan Thomas. Former Ripple CTO. Forgot the password to an IronKey holding 7,002 BTC. Two guesses left before it self-destructs. Worth north of $700M today.
James Howells. Threw away a hard drive in 2013. Spent a decade trying to dig up a Welsh landfill. Courts said no.
The protocol does exactly what you tell it to. Nothing more.
So here's the framework.
Tier one—the daily driver. Five to 25 percent of your stack. A centralized exchange. A hot wallet for DeFi, Bittensor staking, the occasional NFT.
Tier two—working cold. Hardware wallet plus a 25th-word passphrase. Metal backup—stainless steel, stamped or punched, never paper. Coldcard if you're Bitcoin-only. Trezor if you have BTC and select altcoins. Ledger if you hold TAO, ETH, SOL—it's the only mainstream device with support baked in.
Where to put the metal? Not your house. Not the bank. A house gets burgled, burned, or flooded. A safety deposit box gets frozen, drilled by the bank during "renovations," or buried in probate when you die.
The options are wider than people think. A private vault. A sealed envelope with your estate attorney. A trusted relative two states away. A welded capsule buried somewhere. Storage you control, off your property, outside the banking system. Pick what fits your life—just don't pick the two places everyone picks first.
Now, passphrases.
A passphrase is the "25th word." Your hardware wallet generates a 12 or 24 word seed phrase, and the passphrase is an extra word, sentence, or string of characters you make up yourself and add on top.
It lives only in your head or written down somewhere separate from the seed. Same seed, different passphrase, different wallet—the math creates a brand new wallet for every passphrase you try.
So the idea: the seed alone opens Wallet A with a few hundred bucks. Seed plus passphrase opens Wallet B, where the real stack lives.
The passphrase isn't optional here. A stolen seed without the passphrase shows a decoy wallet. With the passphrase, it shows everything.
Tier three—the vault. This is where the real money lives. Multisig. Two-of-three or three-of-five. Keys distributed across geography—home, remote state, attorney, collaborative partner.
Casa runs $250 a year for the standard plan. Built-in inheritance. Unchained does the same—Bitcoin only, regulated, comes with a tamper-evident inheritance kit you can hand your executor.
For the eight-figure crowd: AnchorWatch. Lloyd's of London insurance up to $100M. Miniscript vaults. Named beneficiaries on-chain.
These are not recommendations. Just options worth looking into.
Now—inheritance.
The hard part: crypto is a true bearer asset. No support line. No password reset.
Two problems, both must be solved:
Title—who legally owns it. Solved by a will or trust.
Access—who can actually move it. Solved by a key plan.
Pamela Morgan wrote the book on this.
(Literally: It's called, "Cryptoasset Inheritance Planning: a simple guide for owners.")
Her rule—never put seed phrases or PINs in a will. Wills become public record. Use the will to point at the access plan. Keep the access plan somewhere else.
Write a one-page letter to your spouse. Plain English. What you own. Who to call. What not to do—like, don't paste the seed into a "support" website. Don't post it on Reddit asking for help.
*The letter is not the secret. The letter points to the secret. * Multisig solves inheritance better than anything else, because the same architecture that stops a thief stops your heir from accessing the funds prematurely. Casa pings you every six months. Miss enough pings, your designated recipient gets access. Unchained does the same with sealed envelopes and a concierge who walks your widow through recovery.
One more thing—the step-up basis.
Crypto inherited at death gets revalued to fair market on the date of death. Bought at $1,000, die at $150,000, your heir's basis is $150,000. They pay capital gains only on what comes after.
This usually argues against gifting appreciated coins during your lifetime. Talk to a crypto-aware estate attorney before you do anything clever.
The cheapest thing you can do this week is write the letter.
You can refine the architecture later.
Again, these are not recommendations. They are things worth looking into based on our research. Consult professionals before you do anything.
