MetaMask Launches Smart Transactions to Combat Maximal Extractable Value

MetaMask, the leading Ethereum crypto wallet, is introducing a new feature called Smart Transactions to help users avoid the negative effects of maximal extractable value (MEV). This optional feature will allow users to submit transactions to a virtual mempool before they are officially cemented on-chain. The virtual mempool will protect against certain kinds of MEV strategies and will run simulations of transactions to help users get lower fees. MetaMask's virtual mempool is different from private mempools and is the first step in a more ambitious roadmap to shift how MetaMask routes transactions to Ethereum.
