Custody, self-custody, and what it means for you

“Not your keys, not your coins.” It’s one of crypto’s oldest sayings, and it hides a genuinely important question: when you hold digital money, who actually controls it? Understanding custody is the difference between feeling in control of your money and only appearing to be.

Custodial: someone holds the keys for you

In a custodial setup, a company holds the private keys that control your funds — much like a bank holds your cash. You log in with a password, and they move money on your behalf. It’s familiar, convenient, and recoverable: forget your password and you can reset it.

The trade-off is trust. You’re relying on that company to stay solvent, secure, and honest. For most people making everyday transfers, a well-regulated custodian is a perfectly reasonable choice — the same way you trust a licensed bank.

Self-custody: you hold the keys

With self-custody, the private keys live only with you — in a hardware wallet or a seed phrase you control. No company can freeze your funds, and no company can lose them for you. But there’s no reset button either. Lose the keys and the money is gone for good.

Custody is a spectrum of convenience versus control. The right point on it depends on what the money is for.

Which should you choose?

• Everyday spending and transfers: a regulated custodian is convenient and recoverable.
• Long-term savings you rarely touch: self-custody removes third-party risk entirely.
• Best of both: many people keep a spending balance with a custodian and move larger reserves to self-custody.

There’s no single right answer — only the one that fits how you actually use your money. What matters is that you know which model you’re in, so the choice is yours to make rather than one made for you by default.
