Holding your own private keys so no company can move, freeze or lose your crypto.

✦ Key Insight

Every major exchange collapse has demonstrated the counterparty risk of custodial accounts. Self-custody removes it and hands you the responsibility instead.

✕ Common Misconceptions

Moving to self-custody without a tested backup. Practise a full restore on a spare device with a small amount before transferring anything significant.

Detailed Explanation

In self-custody, you alone can authorise transactions. That removes counterparty risk — no exchange failure can touch your funds — and removes every safety net. There is no password reset and no support line that can restore access.

In Practice

“After an exchange halts withdrawals, holders in self-custody are unaffected because their assets were never on the platform.”
