USO is a tokenized version of the ETF, backed 1:1 by actual shares and issued on the blockchain. It enables users to gain exposure to equity through a digital asset, combining the familiarity of traditional securities with the accessibility and efficiency of blockchain technology.

The United States Oil Fund provides exposure to crude oil through futures contracts, not direct ownership of physical oil. USO is commonly used by investors to speculate on short-term oil price movements or hedge commodity-related risk. It tracks daily changes in WTI crude oil prices and reflects shifts in global energy supply and demand.
