I don't have any specific information on creating a wallet or RazorPay aesthetic with a minimalist background using PNG and vector graphics. However, I can suggest some general design principles that might help you achieve the look you're going for.

To create an aesthetically pleasing design, consider the following:

* Use high-quality images: Utilize high-resolution PNG images that are optimized for web use.
* Choose a limited color palette: Select a minimal number of colors that complement each other and fit your brand identity.
* Optimize vector graphics: Ensure that your vector graphics are scalable and look crisp at different resolutions.

If you're looking for specific design inspiration or code snippets, I recommend searching for "RazorPay wallet design" or "Minimalist wallet UI" on design-focused platforms like Dribbble or Behance.
