Cryptocurrency payment system
603 USD Example: trustee plus
Need to create a similar payment system with integration of Mastercard crypto and with other not very important features, such as settings, withdrawals, card skins, etc. Only write if you have experience, preferably with a team of at least 5-20 people. Please provide examples right away.

Hello! Let me clarify: you are absolutely right — projects like payment systems with crypto integration are not quite correctly categorized as "desktop applications" or simply "blockchain." This is a full-stack fintech product with components:
🧩 What is included in a project like Trustee Plus:
Integration with Mastercard (crypto-friendly) through official partner schemes (for example, through Wirex, Moonpay, Mercuryo, Checkout.com, etc.)
Support for multi-currency wallets (BTC, ETH, USDT, etc.)
In-app exchange (via DEX or aggregators)
… KYC/AML (via SumSub, Veriff, Onfido)
Generation and issuance of virtual/physical cards
Top-ups, withdrawals to card, purchases
UI/UX at the level of Revolut/Trustee
Admin panel for managing users, applications, limits
Security: 2FA, encryption, logging, modular limits
⚙️ Technically, the project consists of:
Frontend: React Native or Flutter (mobile part), Web interface
Backend: Node.js / Go / Python (processing applications, wallets, payment logic)
Blockchain Layer: integrations with RPC, Web3, fireblocks / custodial / non-custodial
Payment gateways: Mastercard Crypto, Moonpay, Transak, Ramp, Binance Pay API
DevOps & Security: Docker, CI/CD, KMS, data encryption, backups
🧠 Team:
We have an experienced team of 12+ people who have worked on similar tasks:
crypto exchanges (web + mobile)
custom wallets with cards
marketplaces and escrow
gateways with Mastercard/Visa (through partners)
banking UI and Web3 fintech
📎 Examples (upon request in DM):
Crypto gateway with top-up and card issuance
Custom P2P exchange with tokens and external payments
NFT marketplace with internal wallet and Web3 integration
📩 Ready to discuss the task, show architecture/portfolio, and assemble the project "turnkey."
💰 Cost and timelines — after assessing the logic of operations and partnerships (Mastercard requires a separate procedure).
We can start with MVP — wallet, internal conversion, basic cards.

Good afternoon. I am ready to complete the task. I work with a team.
