Hi, I can complete your crypto Payment Integration module with secure, testable implementation aligned to your milestone goals. Scope I’ll cover: • Integrate a reputable crypto gateway or direct wallet API (BTC, ETH, or similar) • Implement transaction creation, confirmation callbacks, and robust error handling • Ensure secure key storage (env isolation, encrypted secrets) • Add basic fraud checks and validation safeguards • Deliver clean testnet/mainnet configs + concise setup documentation I understand your acceptance criteria: users must initiate, confirm, and see payment status reflected reliably in the order screen. I’ll build against functional tests to ensure this flow is verifiable end-to-end. Clear communication, milestone delivery, and revisions included to reduce risk. Ready to start immediately. Best Regards, Shabahat Habib

You’re looking to finalize the payment feature of your app by completing the cryptocurrency payment integration, including connecting to a reputable crypto gateway or wallet API and handling transaction callbacks and error states. I understand you also need secure key storage, fraud prevention, and environment-specific configurations for testnet and mainnet, along with setup documentation. With over 15 years of experience and more than 200 projects completed, I specialize in PHP and API integration, which are crucial for this task. My background includes building secure payment modules and integrating blockchain APIs to support Bitcoin and Ethereum transactions within web and mobile applications. I will implement the payment integration using reliable crypto SDKs and APIs, ensuring secure key management and proper handling of transaction confirmations and errors. The setup will include testnet and mainnet configurations, with concise documentation to simplify deployment. I anticipate delivering a fully functional module ready for your functional tests within a few days. Feel free to reach out so we can discuss your milestone requirements in more detail.
