+# Audits
+
+Audits of the formerly shared OP Stack components can be found in [Optimism’s repository](https://github.com/ethereum-optimism/optimism/tree/develop/docs/security-reviews). The audits of the OP Stack components through Upgrade 18 are relevant for Base. Going forward, audits of the Base Stack smart contracts and protocol can be found here.
