Your debit limit is the amount of USDC you can spend using your Exa Card as a debit card.
When you configure your Exa Card as a debit card, each purchase directly reduces your available debit limit. Initially, your purchases will be deducted from your USDC balance. Soon, you’ll have the flexibility to choose which assets to spend and in what order.
If you notice that you can't spend the entire amount of USDC in your wallet, it could be due to how your collateral is managed. If you’ve taken out a loan using your Exa Card's credit feature and you have USDC as collateral, your spending is limited by your Account Health. This means you’ll only be able to spend your USDC until your Account Health reaches 1 to ensure your loan remains secure and your collateralized assets are protected.
To calculate your debit limit there are two main variables to take into account.
USDC deposited
Taken loans: If you have already made purchases using your exa card as a credit card and you have a debt to be paid, your USDC will be used as collateral, so you may not be able to spend the whole amount of USDC deposited. This will vary depending on whether you have other assets in your exam wallet. For example, if you have ETH besides USDC, you will be in a better position to spend more USDC since you also have ETH as collateral.
