# Smart Contract Risk Smart contracts are inherently a new form of financial settlement technology, which may be vulnerable to hacks and exploits. While these risks exist, the USDO smart contract is developed on the back of established code standards that have been battle-tested and widely adopted. In addition to maintaining sound smart contract development and security practices, the USDO smart contract has been formally audited by ChainSecurity for potential security flaws. While every effort has been made to ensure that the USDO smart contract abides by the highest security standards at the time of deployment, there is no guarantee that new attack vectors will not arise in the future, as smart contract technology continues to evolve. Therefore, the OpenEden team will endeavour to comply with the latest security practices and stay abreast of new security exploits. The following are the smart contract audit reports for the USDO token contract: * [USDO Token, Chain Security, September 2024](https://www.chainsecurity.com/security-audit/openeden-usdo) * [USDO Express, Chain Security, March 2025](https://www.chainsecurity.com/security-audit/openeden-usdoexpress) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
