Custodial vs Non-Custodial Wallet
Custodial wallets are held by a third party (like an exchange) while non-custodial wallets give the user direct control of their private keys.
Also known as: self-custody, exchange wallet, CEX wallet

In a custodial wallet, a company holds the private key on your behalf, similar to a bank holding your money. You log in with a username and password and trust the company to keep your funds safe. Centralised exchanges like Coinbase operate this way. The risk is counterparty exposure: if the exchange is hacked, mismanaged, or collapses, your funds may be inaccessible or lost.
A non-custodial wallet means you hold the private key or seed phrase yourself. No company can freeze or seize your funds without access to that key. The risk shifts entirely to you: losing the seed phrase or getting it stolen means irreversible loss with no customer service to call.
The scam landscape differs between the two: custodial wallets are vulnerable to exchange hacks, platform insolvency, and account takeover via SIM-swapping; non-custodial wallets are targeted by seed-phrase theft, malicious approvals, and drainer contracts. Neither model is inherently safer; the relevant question is which risks the user is better positioned to manage.
