Blockchain / Smart Contract Analysis Tool

✏️ What does this tool offer?

• Lets users read, inspect, and interact with Ethereum smart contracts via address or Etherscan URL.

• Syntax highlighting to make code more readable. 

• Dark mode, mobile support, handling large files.

• Shows live, on-chain values (state of contracts, balances, etc.) so you see real data, not just code. 

• Supports multiple networks (Ethereum Mainnet, testnets like Goerli, Sepolia; also other chains like Polygon, BNB Smart Chain, Arbitrum, Optimism, Base) for reading contracts.

• Security / audit features: in particular a GPT-4 powered security review option. 

• Private code pages, comment/rich annotation of code, ability to paste raw code, and permissions control (e.g. via ENS names) for shared or private contract code. 

⭐ What does the tool actually deliver based on user experience?

• Makes exploring and understanding smart contract code faster and clearer, even for large or complex contracts. (syntax highlighting, live values, etc.) Helps developers/auditors see contract behavior in real time (on-chain state) without leaving the tool.

• Enables feedback/collaboration: commenting, private pages, sharing. 

• Provides insights into possible security issues through GPT-4 review. 

🤖 Does it include automation?
Yes — there are several automated or AI-assisted features:
