**Superchain Upgrade 16a** is pending governance approval for rollout on **Sep 22** (Sepolia) and **Oct 2** (Mainnet). This maintenance upgrade replaces U16 with a more cautious approach: - **Removes withdrawal-proving logic** from production based on partner feedback - **Introduces system-level feature toggles** via SystemConfig for per-chain flexibility - **Adds development feature flags** for testing interop features safely **Key improvements:** - ETHLockbox becomes first toggle-controlled feature - Chains on U15 can upgrade directly to U16a - U16 chains can transition seamlessly Interop code remains in the repository for future upgrades. The update focuses on enhanced safety and flexibility rather than new features. [Read full proposal](https://gov.optimism.io/t/maintenance-upgrade-proposal-u16a/10288)
