The DeFi Checking Account

Your funds on Quartz are always kept on-chain and in your custody, meaning no matter what happens to Quartz, your funds stay secure. Through our DeFi integrations you can earn yield on your deposits and off-ramp without incurring any capital gains tax - without any of the complexity usually associated with DeFi.

With Quartz, you can interact with the traditional finance world while staying crypto-native.

Before tapping your phone to pay, you open the Quartz app and select the amount of funds you want to pre-authorize for spending. This gives Quartz access to withdraw those funds should you use your crypto card. If you don’t use your card, or you cancel the authorization, Quartz loses access again. No one else can ever access your funds.

By requiring pre-authorization, Quartz is unable to touch your crypto until you specifically authorize a transaction. This gives Quartz the ability to withdraw that amount and that amount only, so you can be sure your funds stay secure and in your custody no matter what happens.

Pre-authorization also provides stronger protection from fraud, as your virtual crypto card cannot be debited without your permission, even if your card details are stolen.

Pre-authorization is the default, but if you don’t want to authorize each card transaction, you can give Quartz permission to withdraw from your balance whenever a card transaction comes in, without needing your in-app approval. No matter which option you choose, your funds always stay on-chain and you can withdraw at any time.

Your Quartz virtual debit card can be used for both in-person and online transactions. For online card transactions that support 3D Secure, no pre-authorization is needed as confirming the transaction sends the funds to Quartz. For other online card transactions, spending requires the same authorization as
in-person transactions.

Your Quartz account is an on-chain program, controlled by your on-device biometrics and your recovery wallet. This recovery wallet can be an external wallet (such as Phantom or MetaMask), your email, social media account, or a newly generated seed phrase. With the Quartz app you can send and accept crypto, send and accept fiat, convert cryptocurrencies, and spend with a crypto card.

You can buy cryptocurrency with Apple Pay / Google Pay, or by simply sending a bank transfer to your Quartz account. The fiat (euros, dollars, etc.) will automatically be converted into your desired crypto token. You can also sell crypto by spending with your crypto card, or by sending a bank transfer to a fiat bank.
