I need a full-featured crypto exchange, visually and functionally inspired by Fxadvisor.in, but built from scratch so I retain complete ownership of the code. Core trading must cover Bitcoin (BTC), Ethereum (ETH), Ripple (XRP) and fiat pairs against USD, with the flexibility to add more assets later. Key workflows I want ready on day one: • Secure, on-chain wallet management for each user, with hot-cold wallet logic and automated deposit / withdrawal processing. • Integrated video-based KYC that performs real-time liveness detection before an account is approved. The verification should plug into the onboarding flow seamlessly, store audit logs, and give me an admin panel to override or re-verify if needed. I’m comfortable with any modern stack—popular choices like Node.js, React, Laravel, Go, or even a battle-tested white-label platform—as long as the final product is modular, well-documented and easy for another developer to maintain. Security best practices (encryption at rest, rate limiting, 2FA hooks) are mandatory. Deliverables (acceptance criteria): 1. Responsive web app whose UI borrows the clean look of Fxadvisor.in yet carries my logo and color palette. 3. KYC micro-service with liveness detection API successfully approving or rejecting sample users. 4. Post-deployment hand-off: source code in a private repo, basic architecture docs, and a one-hour knowledge-transfer session. If you’ve shipped an exchange or similar fintech product before, please share a live link or screen-cap demo so I can gauge UX and performance.
