Bru Finance: Democratizing Agricultural Credit via RWA Tokenization on Polygon
Bridging decentralized finance with real-world assets to provide instant, low-interest liquidity for global farmers.
THWORKS developed Bru Finance, a decentralized lending platform on the Polygon network that allows farmers to tokenize agricultural commodities as collateral. By utilizing smart contracts and multi-sig custody, the platform provides farmers with immediate access to crypto-backed loans at significantly lower rates than traditional micro-lenders, creating a transparent link between global DeFi liquidity and real-world agricultural assets (RWA).
The Challenge
Small-scale farmers in emerging markets often face interest rates as high as 30-40% from local lenders due to the lack of formal credit history. While they possess valuable physical commodities (grains, spices, etc.), these assets are 'frozen' and cannot be easily used as collateral in the traditional banking system without heavy paperwork and long wait times.
In 2026, the movement of 'Real World Assets' (RWA) onto the blockchain is the key to financial inclusion. Bru Finance needed a secure, low-fee infrastructure that could handle the high volume of small-scale agricultural transactions while ensuring that the physical goods in warehouses were accurately represented and protected on-chain.
Our Solution
We built a specialized DeFi protocol on Polygon that mints tokenized representations of warehouse receipts. When a farmer deposits commodities into a partner warehouse, a 'Commodity Token' is minted, which can then be used as collateral to borrow stablecoins from decentralized liquidity pools.
To ensure maximum trust and scalability, we integrated Chainlink Oracles for real-time commodity price feeds and utilized Multi-Sig custody protocols for the management of the underlying smart contracts. Polygon was chosen as the primary network to ensure that transaction fees remain negligible—a critical factor for loans as small as $100.
Key Technical Decisions
Dynamic LTV Ratios: Implemented smart contract logic that adjusts the Loan-to-Value (LTV) ratio based on the shelf-life and market volatility of the specific agricultural commodity.
Gnosis Safe Multi-Sig Integration: Ensured that all treasury and collateral management functions require multiple authorized signatures, protecting the protocol against internal and external security breaches.
On-Chain Provenance: Every commodity token includes metadata regarding the origin, quality, and storage duration of the physical asset, verified by authorized warehouse auditors.
Results
Before
Farmers waiting weeks for predatory high-interest loans; total lack of transparency in commodity pricing and warehouse receipts.
After
Instant access to global DeFi liquidity; automated lending based on real-time asset value; transaction costs reduced to fractions of a cent.
Technology Stack
"Bru Finance is a game-changer for the agricultural sector. By bringing physical commodities to Polygon, THWORKS has created a pathway for millions of farmers to escape the cycle of debt and join the global digital economy."
Frequently Asked Questions
Common questions about this project and our approach.
The physical commodities are stored in certified, insured warehouses. These warehouses issue electronic receipts that are tokenized by Bru Finance. The physical goods cannot be released unless the corresponding tokenized debt is cleared on-chain.
