Next.js Developer for Crypto Payment Integration

Freelance [login to view URL] & Crypto Payment Gateway Specialist Needed About EchoLive EchoLive is a dynamic livestreaming application built on a modern tech stack ([login to view URL], Firebase, Tailwind CSS). We're creating a vibrant community for streamers and their audiences. We are currently in a prototype phase and are looking for a skilled developer to help us implement a critical production feature. The Project: Production-Ready Payouts The core of this project is to replace our current simulated payout system with a secure, real-world cryptocurrency payment gateway. The goal is to allow our administrators to approve and process withdrawal requests from users, paying them out in USDT. Current State (Simulation) The current payout logic is a client-side simulation inside src/app/admin/withdrawals/page.tsx. It does not perform real transactions. // This is the function that needs to be replaced. async function processPayout( walletAddress: string, amount: number ): Promise<{ success: boolean; transactionId?: string; error?: string }> { [login to view URL](`CLIENT-SIDE: Initiating payout for ${amount} points to ${walletAddress}...`); const usdtAmount = amount / 10000; // 10,000 points = 1 USDT return new Promise((resolve) => { setTimeout(() => { // Simulate a 90% success rate if ([login to view URL]() < 0.9) { const mockTxId = `sim_tx_${[login to view URL]()}_...`; resolve({ success: true, transactionId: mockTxId }); } else { resolve({ success: false, error: "Simulated payment provider failure." }); } }, 2000); }); } Your Mission: Key Deliverables Your mission is to build a secure, server-side payment integration. The deliverables are: Secure Server-Side Payouts: Create a [login to view URL] Server Action to handle the entire payout logic. All API communication with the payment provider must happen on the server. Payment Provider Integration: Integrate a cryptocurrency payment provider. Our preference is Binance, but we are open to other reputable gateways like Stripe or Coinbase Commerce. Environment Variable Security: All API keys and secrets must be stored securely as environment variables and never exposed to the client. You must provide clear documentation for which variables are required. Client-Side Integration: Update the handleAction function in src/app/admin/withdrawals/[login to view URL] to call your new Server Action. The UI must be updated to reflect the real transaction ID on success or display a specific error on failure. Required Expertise Expert Level: [login to view URL] (App Router), React, TypeScript Expert Level: API Integration & Security Best Practices Strong Experience: Firebase (Firestore & Server-Side Actions) Proven Experience: Integrating at least one cryptocurrency payment gateway (e.g., Binance API, Stripe, Coinbase Commerce). Project Details Engagement Model: This is a fixed-price project. Timeline: The project has a firm deadline and is expected to be completed within 1-2 weeks. Budget: The fixed budget for this project is $2,000 USD, paid in USDT. Top Priority: Security. The final implementation will be strictly reviewed to ensure no sensitive keys are exposed and all transactions are handled securely on the server.
