Crumbs is a decentralized application (dApp) designed to enhance web interaction by allowing users to leave and view permanent comments on any website. By utilizing blockchain technology, Crumbs ensures that all comments are permanently stored on-chain, making them accessible to anyone. This innovative tool is reminiscent of the messaging system in games like Elden Ring, where player interactions add depth to the experience.

The functionality of Crumbs revolves around unique hashes generated from website URLs, enabling users to create and submit comments securely. Users sign the hash of both the website and their comment, which is then stored on-chain through a specific contract function. While comments can be substantial, there is a limit of approximately 280 characters for off-chain indexing. Overall, Crumbs provides a novel way to engage with the web community through permanent, traceable commentary.
