Inspiration sample

With the rise of cryptocurrency adoption, scams and shady crypto projects have become a growing concern, especially for beginners. We wanted to build something that could act as a trustworthy watchdog for the blockchain, helping users detect potentially risky or fraudulent crypto wallets and contracts in real time. Our goal was to create a tool that promotes transparency, awareness, and safety in the crypto world

What it does

Verifypto is an AI-powered crypto verification tool that lets users check the credibility of Ethereum wallets and smart contracts.

it: Detects whether a wallet is an individual or a contract Analyzes transaction activity, token transfers, and contract source code Flags red flags like blacklist functions, onlyOwner privileges, and unverified contracts Rates the risk level (Safe, Medium Risk, or Likely Scam) using Google Gemini AI Stores verification history and lets users view their past lookups

In short, Verifypto helps users avoid scams and make informed decisions in Web3.

How we built it

Backend: Python + Flask Smart Contract Analysis: Etherscan APIs (for transactions, contract source, token supply) AI Analysis: Google Gemini API to summarize risks and generate verdicts Database: MongoDB Atlas to store verification history Deployment: Ngrok for quick public API tunneling We wrote custom logic to calculate on-chain risk scores, and Gemini helped us translate raw data into human-friendly insights.

Challenges we ran into

Making sure the app could reliably distinguish wallets from contracts

Interpreting raw blockchain data into meaningful risk indicators

Crafting prompts that Gemini could understand consistently

Handling edge cases like trusted tokens (e.g., USDT, USDC) being flagged unfairly

Learning how to use multiple APIs and services together smoothly

Accomplishments that we're proud of

Our app successfully catches red flags in known scam contracts! It gives easy-to-understand summaries of technical blockchain data. Built a working product from scratch with a team of beginner developers in < 24 hours! Learned a lot about smart contract analysis, AI prompt engineering, and real-world security concerns in Web3.

What we learned

How to use Etherscan and Gemini APIs effectively Prompt engineering for structured AI outputs How smart contracts can be manipulated or hidden to scam people The importance of user-focused tools in crypto Building a project collaboratively in a tight timeframe

What's next for Verifypto

Build a Chrome extension version for quick wallet lookups on Etherscan or OpenSea Expand support to other chains like Polygon, BSC, and Solana Add reputation scores from community votes Let users report scams or flag addresses Integrate with wallet apps for real-time scam detection while transacting
