Smart Crypto Tracker and AI Assistant
COINWETON is a web-based crypto intelligence platform built to tackle market volatility and information asymmetry in digital asset investing. Retail investors often face high market risks, misinformation, and emotional decision-making such as FOMO. COINWETON provides structured, real-time market data alongside automated security vetting, enabling users to make informed, data-driven decisions.
Beyond standard price monitoring, COINWETON integrates an automated smart contract security audit engine to detect honeypots and malicious contracts before users interact with them. It also features Cown AI, a contextual assistant designed to interpret real-time market metrics and contract safety data on demand.
The main dashboard delivers live global cryptocurrency metrics, including prices, 24-hour trading volumes, market capitalization, Bitcoin dominance, and market sentiment tracking through the Fear and Greed Index. The layout is optimized for desktop and mobile workflows with a dark interface.
Visual data inspection uses two dedicated charting implementations:
- Recharts: Custom sparkline visualizations on the dashboard for rapid trend assessment across coin lists.
- TradingView: Interactive technical analysis widgets on individual coin pages supporting multiple intervals (1H, 24H, 7D, 30D, and 1Y).
Automated token risk inspection is powered by GoPlus Security API. Every EVM-compatible token (Ethereum, BNB Chain, Polygon, and others) is screened for:
- Honeypot Verification: Validates whether token sell transactions are blocked or restricted.
- Mint Functions: Checks if the contract owner can arbitrarily inflate token supply.
- Buy and Sell Taxes: Detects hidden slippage fees or extortionate tax rates.
- Ownership Status: Evaluates ownership renunciation and administrative privilege controls.
Audit outputs are summarized with visual risk indicators: SAFE, CAUTION, or DANGER.
An integrated AI assistant built on a two-tier Retrieval-Augmented Generation (RAG) structure:
- Macro Context: Gathers overall market trends, market cap shifts, and global news sentiment.
- Micro Context: Pulls coin-specific telemetry, fundamental statistics, and smart contract audit outputs.
This context grounding keeps responses anchored in live data and prevents hallucinations during technical queries.
A persistent watchlist lets users track target assets across sessions. The authentication system uses Google OAuth integrated with Auth.js, storing watchlist references directly in a serverless PostgreSQL database.
