Inspiration

Online payment scams, phishing links, and fraudulent payment requests are growing challenges in digital finance. Many users struggle to identify suspicious transactions before sending money. We wanted to create an AI-powered solution that makes digital payments safer, smarter, and easier to understand.

What It Does

PayPal AI Guardian is an intelligent payment safety assistant that identifies potential fraud, analyses suspicious payment links, evaluates transaction patterns, and explains security risks in simple language. It provides risk levels and actionable warnings to help users make informed payment decisions.

How We Plan to Build It

We are developing the application using React for the frontend and Python with FastAPI for the backend. Machine learning models analyse transaction patterns, while AI provides understandable explanations of potential threats. PayPal Developer Sandbox will support secure test-payment demonstrations. A dashboard will display transaction information, risk scores, and security alerts.

Challenges

Key challenges include identifying suspicious patterns accurately, reducing false alerts, analysing different types of scam indicators, and presenting complex security information in a user-friendly way. We aim to address these challenges through model testing, sample datasets, and continuous improvements.

What We Learned

This project helps us explore the practical combination of artificial intelligence, machine learning, fintech, cybersecurity, and payment integration. Our vision is to make AI-driven payment protection accessible, understandable, and trustworthy for everyone.

Our Vision

Before every payment, let intelligence protect your money. PayPal AI Guardian aims to create a safer digital payment experience through explainable AI.

PayPal AI Hackathon

Created by

I contributed to the development of **PayPal AI Guardian** by designing the project concept, defining its key features, planning the application workflow, and developing the user interface. I used AI-assisted development tools to support implementation, debugging, and improvements.

My work focused on creating an intuitive fintech security platform with features such as AI-powered fraud detection, fake payment proof analysis, phishing URL scanning, transaction monitoring, and an AI security assistant.

I also worked on project documentation, testing, improving the user experience, and preparing the project for demonstration. My goal was to explore how AI can help improve digital payment security and provide users with better awareness of potential online payment threats.
