ranium.io (XU3O8) is the world's first tokenized uranium, each representing fair ownership of physical uranium, which is stored and verified by Cameco. XU3O8 is an ERC-20 token built on Etherlink (high-speed L2 powered by Tezos technology), combining deep on-chain composability with institutional-level infrastructure. The project opens up the global 24/7 uranium trading channel, which has always been a poorly liquid and limited commodity, while providing a compliant, secure and scalable access to DeFi and traditional finance. Its legal structure also means that xU3O8 is not a securities. The fundamentals of the asset (low correlation with other assets, supply imbalance, demand growth) and its fit with the interests of technology-oriented investors make it an attractive option not only for Web3 users, but also for Web2 traders who previously failed to obtain physical uranium efficiently and conveniently.
