MonDoc

What I've built: MonDoc is a wallet security diagnostic application for the Monad ecosystem that scans active token approvals, classifies their risk levels, enables users to revoke unsafe allowances, and records cleanup activities on-chain with a self-attested wallet health score. The platform integrates wallet connectivity, approval scanning, risk analysis, one-click and batch revocation, and a dashboard that visualizes cleanup history and score progression. Problem solved: MonDoc addresses the common issue of forgotten or unlimited token approvals that remain active after interacting with decentralized applications. These lingering approvals can expose users to security risks, while existing revoke tools often lack Monad-native support and do not provide verifiable on-chain records of cleanup actions. MonDoc improves wallet transparency, simplifies approval management, and creates a permanent on-chain history of security maintenance. What I learned: From this project, I learned how token approvals work in blockchain applications, how to evaluate wallet security using risk-based heuristics, and how to design a non-custodial system where users retain full control of their assets. I also gained insight into integrating blockchain event indexing, smart contract interactions, client-side health score computation, and on-chain logging to build a practical security-focused decentralized application.
