ContractReader is a browser tool for reading and understanding smart contracts. You enter a contract address or an Etherscan URL, and the site shows the code with syntax highlighting, live onchain values, and in-browser code comparison. The homepage lists support for Ethereum Mainnet, Sepolia, OP Mainnet, Polygon, Arbitrum One, BNB Smart Chain, and Base. It also links to example contracts such as Checks, Terraforms, NounsToken, WETH9, and DelegationRegistry. The site is built by two co-founders and links to GitHub, Twitter, and Discord. The homepage does not state a price, an account requirement, an API, or an open source license, so those details are unknown. No pricing page was found. The homepage does not describe GPT-4 security reviews, so that claim is not supported here.
