"Not your keys, not your coins." You've heard it. It used to sound like crypto-Twitter slogan. Then FTX collapsed with $8 billion of customer funds frozen, Celsius locked up a million retail accounts, and Voyager went bankrupt overnight. Suddenly the slogan was a eulogy.
Custody — the question of who actually controls an asset — is the most important security concept in investing, and it's the one most apps try hardest to hide from you. Let's unhide it.
The three roles
Every app that touches your money plays one of three roles:
- Custodian — actually holds the asset. Exchanges, brokers, banks. If they fail, your asset is caught up in the failure.
- Wallet — holds the keys to your asset. Self-custody wallets like Ledger, Trezor, MetaMask. If you lose the keys, the asset is gone. But no third party can touch it.
- Tracker — shows you what you own, but touches nothing. It's a mirror. If the tracker disappears tomorrow, your assets don't move.
Most investors don't know which bucket each app is in. That's by design — apps that blur the line between "tracker" and "wallet" look richer to VCs and give them more reasons to charge you fees.
Where finqt sits
finqt is a tracker. Full stop. We don't custody anything, we don't hold keys, we don't have a "finqt wallet." What we do:
- Read your balances via read-only API keys you create on your exchange
- Show you prices, positions, and performance across every venue
- Give you tools (finqtAI, intelligence, journal) to make better decisions
What we can't do, even if we wanted to:
- Move funds out of your accounts
- Place trades
- See your seed phrases or private keys (we never ask and never store)
- Get compromised in a way that loses you any money
The worst a finqt breach could do is show an attacker what you own. Not pleasant, but nothing moves. That's the contract we sign when we stay out of the custody business.
What this means for you
When you're picking any tool that touches your portfolio, ask one question: what's the worst thing that happens if this company goes away tomorrow?
- For a custodian: your assets are caught up in bankruptcy. You might get them back in 18 months, at 30% of their prior value, after waiving most of your legal rights.
- For a wallet: if you have your seed phrase, nothing happens. You restore into a different wallet and continue.
- For a tracker: you delete the app. You still own everything. You pick a different tracker.
If the answer isn't one of those three clean stories, something is wrong.
A simple rule
Use custodians you trust for the assets you need custody for. Use self-custody wallets for the assets you want to own directly. Use trackers to see everything in one place without adding a new point of failure.
That's how you build a portfolio that survives the next FTX.
