MetaMask introduced Smart Transactions, a new opt-in feature designed to protect against MEV and enhance transaction success rates. The feature shares a similar framework as MetaMask Smart Swaps, which uses a virtual mempool and employs an auction-based system where a network of searchers and builders compete to fulfill user requests. Transactions sent through Smart Transactions are not visible in the public Ethereum mempool. Users can monitor the progress of their pending transactions via the MetaMask portfolio dashboard. Smart Transactions are only available on Ethereum Mainnet and cannot be manually canceled or expedited. Smart Transactions can enabled in MetaMask v11.15 or later.

Comprising of 12 independent members, the Arbitrum Security Council undergoes bi-annual elections to rotate out six members at a time. The council is tasked with executing prompt protocol upgrades in emergencies. Upgrades initiated by the council bypass approval from the Arbitrum DAO, but are still subject to a short delay period.
