Denominator
An AI-assisted onchain claim checker that returns inspectable evidence from The Graph.
Demo
About
Denominator checks numerical claims about selected Ethereum Uniswap v3 pools. Gemini converts a natural-language claim into a structured comparison, which the user reviews. The Graph supplies daily observations pinned to a block hash, and deterministic decimal arithmetic calculates the verdict. Results include the baseline, target value, chart, corrected claim, source query and downloadable evidence receipt.
How it's made
Built with Next.js, React, TypeScript, Gemini, Zod and Decimal.js, and hosted on Vercel. The Graph provides live pool metadata and daily observations from an existing public Uniswap v3 subgraph. The app validates the interpretation, dates and source metadata before calculating a verdict. Project-specific application code was built during the hackathon; frameworks and the public subgraph are existing dependencies.
