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

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.

Store description: Analyze ERC-20 and ERC-721 tokens across Ethereum, Polygon, Arbitrum, Optimism, Base, and World Chain. Produces token metadata, supply, holder concentration, recent transfers, contract verification, and CoinGecko market data for DeFi research, portfolio monitoring, and token due diligence.

Recommended monetization: Pay per event (PPE). Keep the automatic apify-actor-start event at Apify's default $0.00005. Enable the automatic apify-default-dataset-item event at $0.025 per token analysis ($25 per 1,000 analyzed tokens). Do not pass platform usage costs to users after the first pricing validation run unless RPC/explorer failures require paid infrastructure.

Chargeable output mapping: One default dataset item is written for each token analysis. If a token fails after RPC/explorer work, one error item is written and is also chargeable through apify-default-dataset-item.

User-visible limits: Public RPC, CoinGecko, and explorer APIs are rate-limited. Users should provide their own RPC URL or Etherscan-compatible API key for reliable high-volume runs.
