Self-Custody Tiers in Plain Words (2026)

"Not your keys, not your coins" is true. It's also not much help. It doesn't tell you what to do with a few hundred dollars on an app, or a larger amount you'd hate to lose.

A better question is simpler: who can lose this? Every way of holding crypto answers it differently. Some setups mean a company can lose it. Some mean only you can. Some need two people to make the same mistake. This article sorts the common setups into four tiers by that test.

No coin picks and no product names. The tiers work for any coin.

The quick win: write one line per holding

Before reading further, list every place you hold crypto. Next to each, write one line: "If this goes wrong, it's because ___ lost it." Fill the blank with a name: the exchange, the app, me, or me and one more person.

Most people find two surprises. First, they have more places than they remembered. Second, a large share of their value sits where someone else fills the blank.

Tier 1: on an exchange

Who can lose it: the exchange, or anyone who gets into your account.

You see a balance. The exchange holds the keys. That's convenient for buying and selling. It also means your coins depend on the company staying solvent, honest and open for withdrawals.

One point people get wrong: FDIC deposit insurance does not cover crypto assets. It also doesn't protect you if a crypto exchange, custodian or wallet provider goes bankrupt.^[1] If an app suggests otherwise, read the fine print twice.

Where it fits: money you're about to trade, and small amounts. Turn on the strongest login protection the exchange offers.

Tier 2: a hosted wallet

Who can lose it: the provider, partly, and you, partly.

This covers apps that hold your coins for you but feel like a wallet. Some keep the keys. Some split control with you. The test is the same: if the company vanished tomorrow, could you still move your coins? If the honest answer is "I don't know," treat it like Tier 1.

Where it fits: spending money, and a step up in convenience. Read the provider's recovery terms before you rely on it.

Tier 3: a single-key wallet you control

Who can lose it: you.

A software or hardware wallet where you hold the only key, usually backed up as a seed phrase. No company can freeze it. No company can recover it, either. Lose the phrase and the device, and the coins are gone. Let someone see the phrase, and they can take everything.

The basics are dull and they matter:

• Write the seed phrase on paper or metal. Keep it offline, out of photos, email and cloud notes.
• Do one test restore on a clean device with a small amount before you trust the wallet with more.
• Send a small test amount before any large send. Check the first and last characters of the address each time.

Where it fits: long-term holdings you won't touch often, once you've practiced a restore.

Tier 4: multisig

Who can lose it: it takes more than one failure.

A multisig wallet needs more than one key to move coins, for example two out of three. One lost key isn't fatal. One stolen key isn't enough. The trade is complexity. More keys means more places to store them, and a recovery that only works if you documented it well.

Where it fits: larger amounts, held for years, by someone willing to run a yearly recovery drill. Multisig set up badly can be riskier than a well-kept single key.

Moving up a tier has records consequences

Moving coins from an exchange to your own wallet is generally not a taxable event. But if you pay the network fee in crypto, the IRS counts that fee as a digital asset transaction.^[2] Log both ends of the move, with the fee.

There's a second reason to log it. Brokers now report digital asset sales to you and the IRS on Form 1099-DA, but the rules don't cover non-custodial wallets that never hold your coins.^[2] Once coins sit in your own wallet, nobody sends you a form about them. You still have to report sales, and you must work out basis yourself.^[3] The more self-custody you use, the more your own records matter.

The one thing almost everyone skips

Every tier above Tier 1 needs a plan for the day you can't act. A short note for someone you trust that says where things are and who to call. Never what the keys or phrases are. Keep the note somewhere they'll find it, and update it when your setup changes.

What the free checklist covers, and what it doesn't

The free Crypto Records Checklist starts where this article ends. It lists every wallet and account, logs each lot with its fees, flags the events people forget, and includes the self-custody basics above. It's the records half of custody.

What it leaves out is the full system. Choosing a tier for each holding by who can lose it, a yearly recovery drill, a step-by-step plan for moving to cash, and a family note template. A deeper custody guide is coming that covers those.
