Which of the following is NOT a credit risk mitigation strategy available through Stripe?

Transaction limits based on credit score are not a credit risk mitigation strategy available through Stripe. Stripe primarily focuses on payment processing and fraud prevention, where it utilizes various risk assessment tools and machine learning algorithms to evaluate transactions and merchant accounts. While businesses may implement their own credit score assessments for internal risk management, Stripe does not provide a built-in feature specifically for enforcing transaction limits based on the credit scores of merchants.

On the other hand, flagging merchants by risk level, holding funds temporarily, and conducting regular risk assessments of accounts are practices implemented by Stripe to manage and mitigate credit risk effectively. These strategies help in monitoring transactions, ensuring compliance, and safeguarding against potential fraud or default, making them part of Stripe's approach to maintaining a secure payment environment.
