what is mantlefi fr?

MantleFi is a research tool built to check whether the yields shown on Mantle DeFi dashboards are real or misleading. Instead of trusting the percentages that DeFi sites display, it reads data directly from the Mantle blockchain to verify where a yield actually comes from. It separates the interest or fees that make up a real return from the token rewards that inflate the number and can disappear at any time. The project works in two ways. There is a command line engine, written in plain Python with no extra installs needed, that scans every yield pool on Mantle and sorts them into categories such as real yield, reward dependent, price illusion, or wash trading. There is also a chat agent that answers plain language questions like "what is the real yield on Mantle right now" by deciding which checks to run and showing each step. The chat agent uses a free language model from Groq or NVIDIA NIM, but the numbers it reports always come from the on-chain engine rather than the model itself. Any number in a response that cannot be traced back to a source is flagged, and the raw data behind the answer is always shown alongside the summary. The tool also includes a token finder that searches for a given ticker symbol across multiple sources, keeps only matches on the Mantle chain, and prints the contract address so a user can confirm it is the real token rather than an imitation with a similar name. MantleFi does not give buy or sell advice. It only shows what the on-chain data says, leaving the decision to the user. It is free to run, reads only public data, and works only with the Mantle network. A hosted demo is available online, and the project can also be run locally with a short setup process described in its documentation. It was built as an entry for a Mantle research challenge.
