Buy/Sell is powered by Zero Hash, a regulated crypto infrastructure provider. Your Zero Hash account is separate from your Casa account and requires its own identity verification (KYC).

What you can do with Buy/Sell
- Buy bitcoin (BTC), ethereum (ETH), USDC, or USDT using your linked bank account
- Sell crypto and withdraw cash back to your bank
- Set up recurring automatic purchases on a daily, weekly, or monthly schedule
- Send purchased crypto directly to your Casa vault or Pay Key
What you'll need to get started
- A paid Casa membership (Standard or above)
- A Zero Hash account — open one here
- A linked US bank account — learn how
⚠️ Important: Crypto purchased through Buy/Sell stays in your Zero Hash custodial account until you transfer it to your Casa vault. We strongly recommend moving it to self-custody after each purchase for maximum security. See How to transfer crypto to your Casa vault.
