Hi, I can help you develop a compact, production-ready API for trade execution on your DEX perpetual-futures platform. With experience in both Python and Go, I’m comfortable working with either language to implement the trade execution functionality, which includes opening, closing, and adjusting trades along with leverage and side, while ensuring secure user-specific API key signing for every request. I’ll ensure the code is clean, well-structured, and thoroughly tested, with unit tests for the order-routing logic. The API will include rate-limiting and error handling, ensuring that failed or malformed calls are responded to gracefully. Once we finalize the implementation, I’ll provide a concise README with setup instructions and a working sample trade against the testnet. This will be validated with a full cycle of open-modify-close trades on the testnet. Thanks, Hercules

Hello, I understand you need a compact, production-ready Python or Go API for a DEX perpetual futures platform on Ethereum, focused specifically on secure trade execution (open, close, leverage adjustments, and confirmations) with signed requests and testnet validation. I will design a clean service layer that interfaces directly with the provided exchange smart contract/API spec, implementing secure request signing using user-specific API keys as defined in the documentation. The core module will handle order routing for opening, modifying, and closing positions, with strict error handling, retry logic, and rate-limit protection to ensure stable execution under real trading conditions. The codebase will be structured for production use, including modular architecture, clear separation of concerns, and unit tests covering order lifecycle logic. I will also include a concise README with setup instructions and a working example that demonstrates a full open–modify–close trade cycle on the testnet, validating end-to-end execution without manual intervention. Thanks, Asif

@asimaarbi

Hi, I have hands-on experience building trading integrations in both Go and Python, including working with Ethereum-based systems and API signing workflows, and I can share my open-source repositories to demonstrate similar work. I’ll implement a clean, production-ready trade execution API with secure request signing, structured order routing (open/modify/close), proper rate limiting, and resilient error handling. The code will be modular and testable, with unit tests covering execution logic and a clear README showing setup and a sample testnet trade cycle. I’m comfortable structuring this in milestones (prototype → testnet validation → final delivery) and can ensure the full trade lifecycle runs reliably without manual intervention.

@codefusion53

Hi, I understand you need a compact production ready API for an Ethereum perpetuals platform focused on secure trade execution for this phase. The key requirement is to open, close, and modify leveraged positions through correctly signed user requests, return immediate confirmations, and handle rate limits and failures cleanly. I would implement this in Python or Go based on the exchange documentation, with a clear service layer for request signing, order routing, payload validation, response parsing, and graceful error handling. The code would be structured so future features like market data or account endpoints can be added without reworking the execution core. I am comfortable with trading API integrations where signing accuracy, reliability, and clean testnet validation are essential. Before delivery, I would test the full open, modify, and close trade cycle on testnet, verify invalid signature and malformed request handling, confirm rate limiting behavior, and include unit tests for the order routing and request construction logic so the API is stable, maintainable, and ready for extension. Best, Justin

@MancicSoftDev

Hi, I can build your compact DEX perpetual trading API in Python or Go with a clean, production-ready structure focused on reliable trade execution (open, modify leverage, close) exactly as required. I’ve worked on similar trading and blockchain integrations where I handled API signing, smart contract interactions, and safe order execution with proper error handling and rate limiting. My approach is to first implement the core trade flow, then ensure full testnet validation for open → modify → close cycles without manual steps. I’ll also provide clean code, unit tests, and a simple README so you can deploy and extend it easily later. Thanks Nenad

@ivank69

Hi there, Does the DEX use direct smart contract calls for trade execution, or does it require signed REST/WebSocket requests to its own relayer API? For API keys, should the service sign trades with user wallets locally, or only forward already-signed payloads from users? This is a focused first phase because trade execution is the only required scope: open, close, adjust leverage and side, then return clear confirmations. I can build it in Python or Go with clean order routing, request signing, rate limits, error handling, unit tests, and a README with a testnet sample trade. Worked on similar Web3 and DeFi integrations where API logic had to interact safely with Ethereum contracts, signed requests, and trading workflows. The key challenge was avoiding bad nonce handling, malformed signatures, failed transactions, and unclear execution states. Solved it with strict validation, retry-safe transaction handling, clear error mapping, and testnet open-modify-close verification. As a senior software engineer and senior Immunefi security auditor for around 3 years, DeFi protocol safety and API reliability are very familiar to me. Ready to start immediately and deliver the first testnet trading cycle. Best, Ivan

@albertc1996

Hi there, Your biggest risk here is unreliable trade execution — perpetual DEX APIs often reject or mis-sign requests if the signature pipeline or rate‑limits aren’t wired correctly. I’ve built multiple trading modules on Ethereum, so I can deliver a compact client that signs requests exactly as required and confirms every open/modify/close cycle ⚡ I have two quick questions to make sure we’re on the same page: Should the client expose synchronous trade calls only, or do you also need async variants? Does the testnet require gas‑sponsored relays, or will you provide keys with ETH for execution? Let’s discuss your project now! ?
