NFT Collection Analyzer

WHAT IT DOES

NFT Collection Analyzer is a read-only tool that performs deep on-chain analysis of NFT collections. It scans the entire transfer history of any ERC-721 collection to build a complete ownership distribution map. The tool aggregates token IDs, transfer history, ownership distribution, total supply, token holder counts, floor price (from ETH sales), top holder addresses, average holdings, token distribution statistics, contract deployment block, and royalty information. All data is consolidated into a clear dashboard showing exactly how the collection is distributed across holders.

HOW TO USE

Enter any NFT collection contract address and click Analyze Collection. The tool scans the blockchain for all Transfer events, processes them chronologically to build an accurate ownership map, and generates comprehensive statistics. Results include collection name and symbol, total supply, unique tokens detected, total holders, average tokens per holder, maximum holding, estimated floor price from detected ETH sales, and a ranked list of the top 10 holders with their token counts and percentage of the total supply. Each holder address can be clicked to view on a block explorer.

ADAPTIVE LOG-CHUNKING WITH BACKOFF

Public RPC providers enforce wildly different eth_getLogs block range limits — some allow 10,000 blocks, others cap at 1,000, and many reject requests that exceed their internal buffer. Instead of guessing a safe range and failing on the first rejection, this analyzer walks backwards from the latest block in dynamically sized chunks. When a request is rejected, the chunk size is halved and retried immediately. This guarantees that the scan completes on any provider without overwhelming the endpoint, and without giving up after a single refusal. The tool processes transfers chronologically to accurately track ownership changes, automatically adjusting chunk sizes to work within each provider's limits.

WHAT IT CANNOT SEE

This tool cannot detect off-chain metadata or token URIs that are not accessible on-chain. It cannot analyze IPFS content or external web resources. It cannot detect hidden supply or pre-minted tokens that have not yet been transferred. It cannot verify token authenticity beyond basic ERC-721 standard compliance. It cannot predict future collection value or market trends. The tool does not analyze token metadata content, images, or attributes. It does not detect fraudulent or counterfeit tokens that may have been deployed with the same contract interface.

PLEASE NOTE

EVM ONLY. Supports all Ethereum-compatible networks (Ethereum, Goerli, Sepolia, Optimism, Arbitrum, Polygon, and others). This tool works best with ERC-721 collections that follow the standard Transfer event signature. For ERC-1155 collections, analysis may be limited. No Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. Always cross-check findings with marketplaces and official collection sources.
