To open a Wirex Credit line, you need to have an existing, active USDT, USDC, NXUSD, or DAI account to allow credit to be funded. Also, you will need a positive balance on one of the crypto accounts for collateral to be added. 

To open Wirex Credit, follow these steps: 
  

• Go to “Wirex Credit” tab and then press on “Borrow: button; 

• Choose a credit account from the list of available accounts; 

• Choose a preferable ratio, collateral account and borrowed amount and then press “Continue”; 

• Accept the Wirex Credit T&C, confirm the credit details and press on “Confirm”; 

• You will see the list of the credits you’ve made. 

Congratulations! Now you’ve successfully borrowed funds from your crypto holding without spending them!
