**Uranium Digital**, a 24/7 uranium trading platform, is integrating **Chainlink Proof of Reserve** to enhance transparency of its tokenized uranium assets. **Key Benefits:** - Independent verification of underlying uranium assets - Real-time onchain accessibility and transparency - Eliminates trust-based verification systems This integration follows a growing trend of platforms adopting Proof of Reserve technology. Recently, decentralized reinsurance protocol Re integrated the same solution across multiple networks including Arbitrum, Avalanche, Base, and Ethereum. **Why This Matters:** Proof of Reserve provides near real-time onchain verification, ensuring that tokenized assets are fully backed by their underlying physical counterparts. This addresses a critical trust issue in tokenized commodity markets. The move represents another step toward greater transparency in tokenized real-world assets, allowing users to verify reserves independently rather than relying on platform assurances.
