Web3 Token Analyzer — On-Chain Data for DeFi Research

Analyze ERC-20 and ERC-721 tokens across multiple EVM chains. Get structured data on holder distribution, transfer activity, price, and contract status.

Supported Chains

Chain	Explorer	Status
Ethereum	Etherscan	Full support
Polygon	Polygonscan	Full support

Features

• Token metadata: Name, symbol, decimals, total supply
• Holder analysis: Top holders with balance and percentage, holder count
• Transfer activity: Recent transfers with timestamps and amounts
• Price data: Current price, market cap, 24h volume via CoinGecko (no API key needed)
• Contract verification: Check if source code is verified on block explorer
• Multi-chain: Analyze the same token across different chains in one run

Use Cases

• Token due diligence: Check holder concentration before investing
• Portfolio tracking: Monitor multiple tokens across chains
• Research reports: Generate structured data for DeFi analysis
• Alert systems: Integrate with monitoring pipelines

API Keys

• Etherscan API key (optional but recommended): Free tier gives 5 calls/sec. Required for holder data on some chains. Get one at etherscan.io/apis
• CoinGecko: Uses the free public API (no key needed, 10-30 req/min rate limit)
• RPC: Uses public RPCs by default. Provide your own for better reliability.

Cost

Minimal compute. Each token requires 3-6 API calls. Typical run under $0.05 for 10 tokens.
