Tuga went missing for three days once. Not a dramatic disappearance — she was two gardens away, stuck behind someone's shed, and entirely fine. But those three days taught me something useful: the time to work out what you'd do is not while it is happening. I spent the first evening being useless because I had no procedure, only feelings.

Self-custody has the same structure. Everything written about it describes the setup. Almost nothing describes the morning you pick up your phone and the wallet app is gone, or the hardware wallet doesn't turn on, or you've locked yourself out.

So here is the triage, scenario by scenario. Read it now, while nothing is wrong.

1. First: The Rule That Covers Everything

Your coins are not in the device. They are on the blockchain. The device holds a key.

That single sentence resolves most of the panic, because it means almost every hardware failure is an inconvenience rather than a loss. A broken phone, a dead hardware wallet, a wiped laptop — none of these destroy bitcoin. They destroy one copy of the access, and if you did the backup properly, another copy exists on a piece of metal in a drawer.

The genuinely fatal scenarios are only two: you lose the backup as well, or someone else gets the backup. Everything else is a bad afternoon.

2. Lost or Stolen Phone (Mobile Wallet)

If the amount was small and the wallet was properly set up: buy a new phone, install the same wallet, restore from your recovery phrase. Done. Your coins reappear because they were never in the phone.

If it was stolen and the wallet had no PIN or biometric lock, treat it as compromised and move fast: restore the wallet on a new device and immediately send everything to a fresh wallet with a new seed. The thief may have the old one.

For Lightning wallets, check your specific wallet's rules. Channel state matters, and some self-custodial Lightning wallets need more than the twelve words. This is one of the few places where "just restore the seed" isn't automatically enough — which is why you read the backup instructions when you installed it, not today.

3. Hardware Wallet Won't Turn On

Genuinely fine, and this is the scenario the whole design anticipates.

Buy a replacement — direct from the manufacturer, as always — and restore from your recovery phrase. It does not need to be the same brand: recovery phrases follow a common standard, so a seed from one major wallet generally restores into another. (If you used a passphrase, you need that too. If you used multisig, you need the descriptor.)

The dead device is now a paperweight holding a key that also exists on your metal backup. There is nothing on it to protect and nothing to recover from it.

4. Forgotten PIN

Most hardware wallets wipe themselves after a number of wrong attempts. That is the intended behaviour, not a disaster — it's there to stop someone brute-forcing a stolen device.

After it wipes: set it up again and restore from your recovery phrase. The PIN protected the device; the phrase owns the coins.

Do not spend three days guessing. Each attempt brings you closer to the wipe, and the wipe is the recovery path, not the failure.

5. Damaged or Partial Backup

This is where it gets real.

• A few words unreadable? Recovery phrases contain a checksum, and the words come from a fixed list of 2048. Missing one or two words is often recoverable with open-source tools, offline, on a machine with no network connection. Missing four or five usually is not.
• Water, fire, fading ink? This is exactly why the advice is metal and two locations. If one copy is damaged, use the other immediately, move everything to a newly generated wallet, and rebuild both backups from scratch.
• You think a copy may have been seen? Treat it as compromised. Generate a new wallet, move everything, and don't reuse the old seed for anything, ever.

6. "I Sent It to the Wrong Address"

The hardest paragraph in this article, and I won't soften it: bitcoin transactions cannot be reversed. There is no support line, no chargeback, no authority. If funds went to an address nobody controls, they are gone permanently. If they went to a person or a company, recovery depends entirely on their willingness.

If it's unconfirmed and your wallet used RBF, you may be able to replace the transaction with a higher-fee one back to yourself. Check immediately — that window is minutes, not hours.

And then: anyone who contacts you offering to recover it is a thief. Without exception. That is a rule with no edge cases.

7. The Procedure, Written Down

Everything above assumes you know where things are. So the actual preparation is one page, written while calm:

• Which wallets exist, and what's roughly in each.
• Where each backup lives, physically. Both copies.
• Whether a passphrase exists, and where it's recorded — separately.
• Which app opens which device.
• The name of one person you'd call before doing anything irreversible.

Keep it with your will, never with the seeds. Its purpose is to turn a panic into a checklist — for you at 2am, and for your family if you're not there.

The Point

The three days were only bad because I had no procedure. When she came back the second time, years later, I knew exactly what to do: the neighbours, the sheds, the shed behind the sheds, in that order, with a torch. It took forty minutes and I never had to feel useless.

Nothing in self-custody has to be a catastrophe. Devices fail and phones get stolen and people forget PINs — the system was designed knowing that, and the metal in your drawer is the answer to almost all of it.

The coins aren't in the device. Write down the procedure while the sun is up. 🐾⚡

Not financial advice — I feed a cat and write about Bitcoin, which qualifies me for neither profession. Follow your specific wallet's official recovery documentation, never a stranger's.
