Inspiration

Many people, especially students and beginners, start trading crypto without really understanding basic financial concepts like risk, position size, and diversification. They see prices and charts, but not how a single trade can affect their overall financial health. I wanted to build a tool that uses simple visuals and clear language to teach risk awareness directly on top of a real wallet, so financial literacy is learned through real behavior, not just theory.

What it does

Blockchain Account Manager connects to an EVM wallet and shows a clean dashboard with assets, recent transactions, and a price chart. When a user enters a potential buy or sell order (price and amount), the app uses AI to generate an easy-to-read “risk coach” message and a simple risk level. It helps users see if they are putting too much of their portfolio into one trade and encourages safer, more informed choices, supporting basic financial literacy around risk and exposure.

How we built it

We built the frontend with HTML, CSS, and vanilla JavaScript for a lightweight and accessible experience. Using ethers.js, the app connects to EVM-compatible wallets to read balances and recent on-chain transactions. A small Node.js and Express backend acts as a proxy to an LLM API. It sends order and wallet context to the model and returns short, focused risk explanations to the UI. Lightweight Charts is used for the price chart, keeping the interface simple but informative for users learning about markets.

Challenges we ran into

One challenge was deciding what financial information is most important for beginners without overwhelming them. We had to choose a small set of signals—like position size relative to total assets and basic volatility hints—and express them in very simple language. Tuning the AI prompts so that responses stayed short, clear, and educational, instead of long or speculative, was also a key challenge.

Accomplishments that we're proud of

We are proud that the app turns a normal crypto wallet view into a small financial education tool. Users can see their real on-chain data and immediately get risk explanations connected to their own actions, not just generic tips. We also like that the design stays clean and beginner-friendly, while still integrating blockchain data, charts, and AI in the background.

What we learned

We learned how hard, but important, it is to translate financial and economic ideas—like risk, concentration, and exposure—into language normal users can actually understand. We saw that combining real wallet data with AI is a powerful way to teach financial literacy at the exact moment when users are about to make a decision. On the technical side, we learned more about safely connecting web3 tools with an AI backend while keeping the UX fast and simple.

What's next for Blockchain Account Manager

Next, we want to add more educational features, such as small tips about diversification, dollar-cost averaging, and emergency funds, tailored to the user’s behavior. We also plan to integrate more metrics, like portfolio concentration by asset and simple risk scores over time, so users can see if they are getting safer or riskier. In the long term, we want this to be a friendly first step into both crypto and financial literacy, helping students and beginners build better habits as they learn about economics and markets.
