OUSD is built on top of other DeFi platforms like Aave, Compound, and Curve that add additional smart contract risk. We are choosing to work with platforms that have literally billions of dollars of assets under management and have made a reasonable efforts to ensure the security of their protocols. However, there are no guarantees that the underlying third-party platforms will continue to work as intended, and any failure in an underlying strategy would potentially lead to a loss of funds for OUSD holders.
