Blockchain Analytics/Next.js
Crypto Token Analysis & Portfolio Management Platform
Full-Stack Developer · Client project
A full-stack blockchain analytics platform enabling crypto investors and traders to analyze newly deployed tokens, evaluate project legitimacy, and monitor portfolio performance in real time, combining on-chain data analysis, automated security checks, and market intelligence to help avoid scams like honeypots and rug pulls.
Honeypot & rug-pull detection
On-chain analysis
Telegram bot
Redis-cached search
The Challenge
New tokens launch constantly, and traders have seconds to judge whether one is legitimate or a honeypot / rug pull — but the on-chain signals are scattered across sources and slow to gather manually.
The Approach
Built a Next.js + Python platform that aggregates Etherscan and on-chain data on a single contract-address lookup, runs automated security checks (ownership, liquidity locks, honeypot detection), stores results in PostgreSQL, and caches with Redis for fast repeat lookups — also exposed through a Telegram bot for instant verification.

- Rug pull risk assessment using multiple security parameters
- Holder distribution and whale concentration analysis
- Live market metrics: price, liquidity, market cap, trading volume
- Portfolio tracking with real-time token valuation
- Telegram bot for instant token analysis using contract addresses
- Fast search with optimized response times through intelligent caching
Technical Highlights
- Modern web application built with Next.js for a fast, SEO-friendly experience
- Backend and blockchain processing modules built with Python
- Integrated the Etherscan API for verified contract data, transactions, and blockchain events
- PostgreSQL for reliable storage of accounts, portfolio data, and analytics
