# TitleChain: The Decentralized Property Ledger
TitleChain is a decentralized application (Dapp) built on the Sepolia blockchain Testnet that enables secure and transparent recording of property titles. Using OpenZeppelin ERC721 Standard, this Dapp allows users to tokenize property titles into NFTs (Non-Fungible Tokens) along with associated metadata. Furthermore, it leverages IPFS for immutable and decentralized storage of essential documents. The Dapp includes a feature to filter titles based on the instrument number. It also implements a role-based access control system, allowing authorized users to approve property titles after verifying associated documents and information.
