WHY SELF-CUSTODY, WHY NOW
"Exchanges" aren’t always safe
Crypto left on an exchange or online wallet isn't, legally or practically, under your own control. Handing over your keys means handing over access to your assets themselves.
Sudden account freezes
Deposits and withdrawals can be halted without warning, often citing regulatory compliance or internal review — sometimes with no explanation or timeline for resolution.
Withdrawal and service suspensions
Changes in an exchange's financial condition or the regulatory environment can suspend withdrawals altogether, sometimes for a long time.
Exchange insolvency
Major exchanges have collapsed in the past, leaving many users unable to withdraw the assets they had deposited. As long as your crypto sits on an exchange, this structural risk never goes away.
EXCHANGE VS SELF-CUSTODY
Exchanges vs. Tangem: what's actually different
Here's how leaving your crypto on an exchange or online wallet compares to managing it yourself with Tangem, point by point.
| Comparison | Exchange / online wallet | Tangem (self-custody) |
|---|---|---|
| Who holds the private key? | The exchange's servers (not you) | You — in the chip inside your card or ring |
| If the exchange goes bankrupt | You may be unable to withdraw your assets | Unaffected — has nothing to do with any exchange |
| Risk of freezes / withdrawal halts | Can happen due to compliance or internal review | No third party has the power to freeze it |
| If the servers get hacked | Entire exchanges have had funds stolen in the past | Keys stay offline — unreachable over the internet |
| Seed phrase handling | Managed by the exchange (not disclosed to you) | Can be skipped entirely (keys generated in-chip) |
| Everyday use | Log in with an ID and password | Just tap your phone |

FAQ
Frequently Asked Questions
Tangem is built on an open, decentralized design, so your access to your crypto doesn't depend on the company's continued existence or its servers. Transaction signing happens entirely inside the chip on your card or ring, and transactions go straight through public blockchain APIs. Even if the app were removed from app stores, an already-installed copy keeps working, and the open-source code is publicly available on GitHub if you ever need to reinstall it. That's the fundamental difference from keeping assets on an exchange.
