Hi, I have suggestions for improving the currency switcher API and application. I can implement multiple currency options in the app history, charts, and other sections by creating a currency conversion model. This model will select the correct exchange rate from an API based on the user's selected currency and convert any monetary values from the default currency to the selected one. I can separate the /token/xrp endpoint into its own page by creating a new route and component to display XRP metrics only. I have some questions to help me complete this work: 1. Which currencies should be supported initially beyond USD? 2. Where is the currency currently selected and stored - in the frontend or backend? 3. What database does the app currently use to store historical data? 4. Are there any rate limiting or caching strategies in place for external APIs? To connect, please provide me with the GitHub repository or deployment URL so I can review the existing codebase. We could then schedule a call to discuss requirements and next steps in more detail. Thanks.

Hi , How are you ? Mission - I understand this project involves enhancing an existing Express API to implement a currency switcher feature and make some modifications to the API endpoints. I recognize 2 tasks mainly - 1) Implement Multiple Currencies: This involves extending the functionality of the existing API to support multiple currencies (USD, CNY, JPY, EUR) in various parts of the application. This would involve changes to how currency data is fetched, stored, and displayed in the app's history, charts, and other sections. 2) Separate /token/xrp into its Own Page: This requirement suggests that the '/token/xrp' endpoint, which presumably displays metrics related to XRP, needs to be segregated or moved to its dedicated page. This would involve modifying the API structure so that the XRP-related metrics are no longer displayed on the main landing page but are accessible through a separate endpoint or page. Looking forward to catch up :) Thanks, Gaurav
