Self-custody vs custodial: what it means for your crypto
"Self-custody" means you — and only you — control the private keys to your crypto. "Custodial" means a company holds your funds for you. This distinction is the single most important thing to understand when choosing a crypto card or wallet.
Custodial: convenient, but not yours
With a custodial service (most exchanges and card apps), the company holds your coins. It is easy, but you are trusting a third party — and you can be frozen, hacked or locked out, the very risks crypto was built to avoid.
Self-custody: your keys, your funds
With self-custody, your crypto stays in a wallet you control, on-chain and auditable. A self-custody card spends against that balance without ever taking custody. If the provider disappeared, your funds would be unaffected.
Frequently asked questions
What is a private key?
A private key is the secret that controls a crypto wallet. Whoever holds it controls the funds. In self-custody, only you hold it.
Which is better for a card?
If you value control and security, a self-custody card is better — your funds stay in your own wallet while you spend anywhere Visa is accepted.
