Tokenized uranium holders can now use xU3O8 as collateral to borrow stablecoins through a new integration with the Morpho lending protocol, accessible via the Oku DeFi aggregator. The announcement was made by Metals.io on March 30, 2026, enabling investors to access liquidity in USDC without selling their underlying physical uranium positions.
How Tokenized Uranium Works
Each xU3O8 token represents digital ownership of physical uranium securely stored in a regulated depository operated by Cameco, one of the world's largest uranium providers. When a user deposits xU3O8 into a Morpho lending pool, the protocol automatically calculates the loan-to-value ratio based on real-time uranium pricing. Currently only USDC is available as the borrowable stablecoin, with plans to expand to other assets in the future.
Demand Drivers: AI Data Centers and Low-Carbon Energy
The launch comes amid surging global demand for nuclear energy, driven by AI data center electricity consumption and low-carbon initiatives. Uranium, a strategic commodity, exhibits significantly lower volatility compared to traditional crypto assets, making it an attractive collateral type for DeFi. By bringing real-world assets (RWAs) into decentralized finance, Metals.io aims to improve capital efficiency—idle uranium can now generate borrowing power.
Technical Architecture and Security
The lending functionality is powered by the Morpho decentralized protocol, which provides open-source smart contracts for lending pools, interest rate models, and liquidation logic. Oku serves as the user interface aggregator where global investors can connect their wallets and access the market. The underlying physical uranium is audited periodically by third parties to ensure a 1:1 backing of xU3O8 supply.
