Conexus Crypto, a leading cryptocurrency exchange platform, required a specialized web page to facilitate cryptocurrency transactions in Vietnamese Dong (VND). The objective was to create a mobile-optimized calculator that would enable users to convert VND into various cryptocurrencies, display wallet information for transfers, and forward transaction details via Telegram and Google Sheets.
Users enter the amount they need in VND (e.g., 5,000,000 VND).
Users choose from five available cryptocurrencies. Each option displays the equivalent amount in cryptocurrency and the respective exchange rate fetched from Yahoo Finance. A variable markup is added to the final cryptocurrency total, based on the purchase amount.
Users are presented with a QR code, wallet number, and the amount in the chosen cryptocurrency for the transfer.
Users upload a screenshot of the transfer, which is sent to the operator via Telegram and recorded in Google Sheets for further processing. Alternatively, they upload a URL to the completed transaction.
Users are redirected to a thank-you page with additional information and contact details for future transactions. Transfers need to be manually confirmed for security reasons, and users are informed of the ETA.
A complex input form was created using WP Forms 7 and custom HTML/JS/CSS (support 3 languages) to capture the amount in VND. Input checks were placed (forced numbers, no text, reg exp to exclude some characters). Input data was sanitized thoroughly. A minimum-amount info message was added (allowable transactions needed to exceed 10 USD.).
Example: User inputs 5,000,000 VND.
JS scripts fetch exchange rates from Yahoo Finance. Display cryptocurrencies table with respective rates.
Example Rates:
Ensured exchange rates were updated automatically in real-time, with minimal calls.
Generated equivalent total to be transferred in the chosen cryptocurrency, after markup and conversion. Displayed wallet numbers and QR code for the chosen amount dynamically.
Example: Final total: 200 USDT. Transfer to Wallet QR or number: 123456.
Integrated a file upload feature for users to submit transfer screenshots. Utilized PHP to handle file uploads and store references in a database. Sent transaction details, including partner UTM tags (fetched form the URL), to the operator via Telegram and Google Sheets API.
Implemented language support in English, Russian, and Vietnamese. Texts provided by the client were integrated into the platform. Users could switch languages seamlessly.
The project was successfully launched and met all client expectations. Key achievements include:
Conexus Crypto Exchange appreciated the timely delivery and the robust functionality of the crypto calculator. They particularly valued the seamless integration with Telegram and Google Sheets, which streamlined their transaction confirmation process.
The client has requested multiple enhancements, which will be implemented in the future:
This case study highlights the successful development and deployment of a cryptocurrency calculator for Conexus Crypto Exchange by a lone developer. Also, it showcases how everyday WordPress and PHP can create specialized financial tools affordably.
