Core Devs | Gift Card With Blockchain

About This Product

The Gift Card Shop is a secure and innovative online marketplace that allows customers to purchase gift cards using USDT on Binance Smart Chain (BSC) and TRON (TRC). This platform offers seamless payment methods, including wallet-based checkout and QR code payment via NowPayments.io. Customers can browse a wide selection of gift cards, make purchases with cryptocurrency, and enjoy automated email delivery of their gift codes instantly after payment confirmation.

The system also integrates blockchain verification in real time, ensuring the security and authenticity of transactions. The admin dashboard provides complete control over inventory management, transaction monitoring, and earnings reports, while real-time customer support is available through Tawk.to integration. The platform was built with scalability and security in mind to accommodate growing demands and evolving technologies.

Our Contribution

We were responsible for architecting, developing, and deploying the entire Gift Card Shop platform. Here’s a breakdown of our contribution to the project:

End-to-End Development – We handled both the frontend and backend development, ensuring the integration of blockchain functionality and the implementation of secure crypto payment solutions. The frontend was designed to provide a smooth, user-friendly experience, while the backend was optimized for real-time payment tracking and automated email delivery.
Blockchain Integration – We implemented wallet-based checkout systems using Web3.js for BSC and TronWeb for TRC. This enabled secure and seamless payments via MetaMask (BSC) and TronLink (TRC), accommodating crypto-native users.
QR Code Payment Integration – Using NowPayments.io, we integrated a dynamic QR code system for users who may not be familiar with Web3 wallets, offering an easy and secure alternative.
Real-Time Blockchain Verification – Blockchain transactions are verified instantly using Web3.js and TronWeb, ensuring complete security and transparency for each purchase.
Automated Gift Card Delivery – After payment confirmation, the gift card code is automatically revealed to the user on the frontend, and a confirmation email is sent to the provided address.
Admin Dashboard – We built an intuitive and secure admin dashboard that allows the client to track transactions, monitor earnings, and manage the inventory effortlessly.
Customer Support Integration – We integrated Tawk.to to provide real-time live chat support, ensuring a seamless customer service experience throughout the transaction process.
