Tokenized Cows Secure Nearly $20K Credit on Brazil's B3 Exchange
Ten dairy cows in Paraná, Brazil, were tokenized via Cowmed collars and used as collateral for credit on the B3 exchange.

Ten dairy cows in Paraná, Brazil, have been tokenized on the B3 exchange using Cowmed collars that encrypt health, behavior, and location data. The tokenized identities allowed the cows to serve as collateral for nearly $20,000 in credit.
The initiative aims to reduce the 'haircut' lenders apply and prevent lenders from pledging the same asset multiple times. This is part of a broader effort to bridge an estimated $8 trillion global finance gap for underserved assets.
How the tokenization works
Each cow wears a Cowmed collar that collects and encrypts data points such as health metrics, movement patterns, and location. This data is then recorded on a blockchain, creating a unique digital identity for each animal. These identities are then used on the B3 exchange to secure loans.
- Cowmed collars gather real-time data
- Data is encrypted and stored on blockchain
- Tokenized identities are accepted as collateral on B3
The project demonstrates the potential of tokenizing real-world assets to unlock liquidity in traditional finance sectors, such as agriculture, where collateral verification is often challenging.
