Platform Features:
-Merchant onboarding (via email + KYC placeholder form)
-Crypto-to-crypto payment gateway (checkout link or API)
-Generate address per transaction (BTC, ETH, TRX, etc.)
-Monitor incoming payment
-Display tx status in merchant dashboard
-Conversion logic
-Incoming token auto-converts (e.g. BTC → USDT, SOL → USDC)
-Use real-time price feed (CoinGecko or Chainlink)
-integrate with aggregator like 1inch, Jupiter, etc.
-Admin panel
-Manage users, wallets, fees, and limits
-Merchant dashboard
-View transactions, balances, logs
-Generate new payment requests
-API & Webhook support
-Allow merchants to integrate payments via REST API
-Security-first architecture
-Cold-wallet compatibility (multi-sig preferred)
-Basic transaction approval logic (admin/manual mode)

Features(Until now):
-Basic analytics / reporting (volumes, pairs, conversions)
-Language toggle (EN / AR later)
-Auto-routing to best stablecoin network (TRC-20 preferred for fees)

Tech Requirements / Stack (suggested, not mandatory):
-Backend: Node.js, FastAPI, or Laravel
-Frontend: React, Vue, or clean HTML/CSS
-Blockchain integrations: Web3.js, Ethers.js, TronWeb, Solana Web3, BlockCypher, Bitcore, Moralis, or NowNodes
-DB: PostgreSQL or MongoDB
-Hosting: Dockerized preferred, otherwise VPS (e.g. DigitalOcean)

Deliverables:
Full source code (with comments)

Admin + merchant frontend
API documentation (Swagger or Postman collection)

Timeline:
Preferably delivered in 3–5 weeks max (MVP). Agile delivery welcome (phased milestones).

Budget:
-We are early stage and need a lean MVP — please bid accordingly. Preference for:
-Teams or individuals with proven crypto PSP experience
-Demos of similar projects (Match2Pay-style) are a big plus
-Open to staged development if needed

Apply If:
-You’ve built or integrated blockchain payments before
-You’re familiar with multi-chain architecture
-You can build secure, scalable APIs
-You want to partner with a long-term crypto project
