Audits

Continuously audited

Origin has a continuous auditing agreement with OpenZeppelin to review 100% of the OETH and OUSD smart contract changes. OpenZeppelin has audited Coinbase, Ethereum, Aave, Compound, and other leading projects. They are one of the most trusted auditing firms in the industry and we are thrilled to count them as part of our extended team.

At launch, OETH utilized 95% of the same code as OUSD and has since been simplified with the removal of LST collateral and farming strategies. Changes were audited by OpenZeppelin and Narya prior to launch. OUSD has also been thoroughly audited by multiple other top security firms, including Trail of Bits and Solidified.
