Overview

What it is

HoofLedger is a decentralized platform for tokenizing and auctioning cattle in Brazil via NFTs. Rural producers turn their livestock into digital assets and trade them on a blockchain marketplace, bringing transparency, traceability, and new market opportunities to agribusiness.

Built during ModularHack, organized by Modular Crypto, the project won 1st place in the general track and the Scroll track. It was my first hackathon.
