I'm looking for a C# library that allows both placing/cancelling limit and market orders on the Jupiter exchange ([login to view URL]). Key Requirements: - Order Management: The library should be able to send async limit and market orders to the exchange and also be able to cancel these orders when necessary. - Robust error handling to manage different types of failures, including network issues and invalid order parameters. All parameters that Jupiter accepts need to be available ie setting priority fee, slippage (dynamic/fixed) Response from Jupiter with success or failure along with actual amounts swapped and transaction hash Access to wallet/account should be via private key. Needs to work with .net 8.0 Ideal Skills and Experience: - Proficient in C# with experience in developing trading libraries. - Familiarity with Jupiter exchange ([login to view URL]) is necessary. Suggested skeleton code: Wallet w = new Wallet(privateKey, publicKey); string inputTokenAddress = "So11111111111111111111111111111111111111112"; string outputTokenAddress = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"; ulong qty = 1; // 1 SOL var swapResult = await [login to view URL](w, inputTokenAddress, outputTokenAddress, qty); string side= "sell"; decimal limitPrice = 300; var lmtResult = await [login to view URL](w, inputTokenAddress, outputTokenAddress, qty, side, limitPrice); EDIT : Needs to be done by 11th November, personal project with a max budget of £200/$250.

I have successfully completed similar projects in the past, specializing in developing trading libraries and integrating with exchanges. Here is a proposed technical approach for the C# Library for Jupiter Exchange Integration: 1. Develop a C# library utilizing .NET 8.0 to interface with the Jupiter exchange's API: - Implement functions for sending async limit and market orders. - Include order cancellation functionality when required. - Ensure availability of all parameters accepted by Jupiter, such as setting priority fee and slippage. - Implement robust error handling to manage various failure scenarios, including network issues and invalid parameters. - Capture response details from Jupiter, including success/failure status, swapped amounts, and transaction hash. 2. Utilize private key authentication for accessing the user's wallet/account on Jupiter exchange. 3. Leverage the suggested skeleton code as a basis for wallet initialization, token swapping, and order placement. 4. Testing and Integration Plan: - Perform unit testing to validate the core functionalities of order management and error handling. - Conduct integration testing with Jupiter exchange's sandbox environment to ensure seamless communication. - Collaborate with the client for real-world testing using test funds to validate the library's performance. 5. Performance and Scalability Optimization: - Implement efficient data processing techniques to enhance performance. - Design the library with scalability in mind to accommodate potential updates or increased user load. By following this structured approach, the C# library for Jupiter Exchange Integration will meet the client's requirements effectively and ensure a reliable and user-ready solution within the specified timeframe and budget.
