I have between three and five NFTs that sit on Ethereum under a single owner address. Time is tight—I need a complete technical breakdown within 48 hours. Here is what I expect: • Contract review: read every ERC-721 function the collection relies on (custom extensions, hidden mint logic, royalty splits, upgrade hooks, etc.). • Data extraction: surface all on-chain storage, tokenURI targets, and any off-chain JSON they reference. • Historical view: map transfers, approvals, and any unusual calls so I see the full ownership and transaction trail. • Plain-English report: spell out exactly what each token does, what data lives where, and any risks or surprises you uncover. Feel free to use Etherscan, Hardhat, Foundry, [login to view URL]—whatever tools get you there fast, so long as the end result is clear, accurate, and delivered inside the two-day window.

I can deliver a full technical breakdown of your NFTs within the 48-hour window. I’ll review the ERC-721 contract in detail, including any custom extensions, royalty logic, hidden mint mechanics, or upgrade hooks. I’ll extract all on-chain data such as storage variables, tokenURI endpoints, and associated off-chain metadata. I’ll also map the full transaction history—transfers, approvals, and unusual calls—to give you a clear ownership and activity trail. Using tools like Etherscan, Hardhat, and Foundry, I’ll produce a plain-English report explaining what each token does, where its data lives, and any risks or anomalies discovered. The final report will be structured, easy to understand, and delivered within 48 hours.

Hello, How are you? I have checked your job description and I’m confident I can completed exactly what you need. I have extensive experience with Ethereum smart contract auditing, NFT ERC‑721 analysis, and fast on‑chain/off‑chain data extraction. Your request for a complete audit of three to five NFTs, including contract review, storage mapping, tokenURI inspection, historical tracking, and a plain‑English technical report within 48 hours aligns perfectly with my skills. I can quickly break down custom logic, hidden mint mechanics, royalty implementations, and upgrade hooks while reconstructing full transaction histories using Etherscan, Foundry, Hardhat, and custom scripting. So I think this job is an ideal match with my skills and experience. Please send me a message so that we can discuss more. Thanks Taras

Hi there, I’ve reviewed your requirement for a detailed technical audit of 3–5 NFTs on Ethereum under a single owner address, including contract analysis, on-chain/off-chain data extraction, and transaction history mapping within a 48-hour window. I can perform a comprehensive breakdown covering ERC-721 contract functions, including any custom extensions such as hidden mint logic, royalty configurations, and upgradeable patterns. I will extract and analyze on-chain storage variables, tokenURI mappings, and any linked off-chain metadata (JSON) to ensure full visibility into how each NFT is structured and behaves. Additionally, I will map the complete historical activity for each token, including transfers, approvals, and any unusual or internal contract interactions, to provide a clear ownership trail and highlight any anomalies or risks. Deliverables: • Contract-level analysis of all relevant functions and extensions • Extraction of on-chain data and off-chain metadata references • Full transaction and ownership history mapping • Clear, plain-English report explaining each token’s structure, data location, and behavior • Identification of potential risks, dependencies, or unexpected contract logic I will use appropriate tools such as Etherscan, web3 libraries, and local blockchain simulation frameworks to ensure accuracy and completeness. Best Regards, JP

Hi, I can deliver a complete ERC-721 breakdown within 48 hours—covering contract logic, tokenURI/data sources, full transaction history, and any hidden behaviors or risks. I use Etherscan + Hardhat/Foundry + scripts to verify both code and on-chain data, then provide a clear, plain-English report per NFT. Ready to start as soon as you share the contract address and token IDs. Liudmyla
