Credit Card Transactions
Credit Cards
Starting with version 1.4, Kima supports credit card transactions in the origin network (onramping)- off ramping to come in a future release. See Upgrading to v1.4.x for more information on how to upgrade your integration.
Credit card transactions require the use of the Kima Transaction Widget. This is a frontend React component which handles integreation with Kima and 3rd party components which handle KYC and payment processing.

Overview
The following steps outline the process of using the widget to buy stablecoins like USDC using a credit card.
From the "Source Network" dropdown, select "Credit Card"
From the "Target Network" dropdown, select the desired chain and token- i.e. USDT on Arbitrum
Fill in the wallet address (Target Address) and amount, then click "Next"
Choose where the service fees will be paid from and click "Next". There are 2 options. The difference is where the service will be paid from.
In the first option, the service fees are paid upfront on the credit card. Choose this option to receive the exact amount you specified in the "Amount" field.
In the second option, the service fees are deducted from the amount you will receive. So you will get slightly less stablecoins the amount you specified in the "Amount" field.
When you have confirmed all details, click Next. This will load the credit card provider screen.
From here there are couple differences between the Testnet and Mainnet versions of the widget.
Testnet Version
