What is the Buy/Sell feature in Casa?

Casa's Buy/Sell feature lets you purchase and sell bitcoin and other crypto directly in the Casa app, then transfer it straight to your vault for self-custody.

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

⚠️ 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.
