It would be insightful to understand the nature of this partnership and how it contributes to the security, efficiency, and scalability of Synapse's services. Additionally, I'm wondering if this banking relationship has any implications for the customers of Synapse, particularly in terms of accessibility, fees, and compliance with regulatory requirements.
