Compare hot wallets, cold wallets, and exchange custody so you can ask better questions before storing keys.

Custody is the first decision

A wallet is software or hardware that stores the keys controlling your crypto. "Not your keys, not your coins" is shorthand for custody risk: if someone else holds your keys, they control access.

Exchange accounts feel like wallets but often mean the platform custodies assets on your behalf. That can be convenient for beginners but adds counterparty risk.

Hot wallets vs. cold wallets

Hot wallets stay connected to the internet — mobile apps, browser extensions, desktop software. They are convenient for frequent use but exposed to malware, phishing, and device theft.

Cold wallets keep keys offline — typically hardware devices or paper backups. They add steps for every transaction but reduce remote attack surface.

Questions before you choose

How often will you move funds? What asset and network do you need? Do you require multi-signature or shared access? Can you securely store a seed phrase offline?

Review the wallet provider's reputation, update history, and open-source status. Never share seed phrases with support chats, forms, or "verification" links.
