This update activates the Gas Station feature when users turn on Smart Transactions via MetaMask Swaps. It streamlines and speeds up transactions by incorporating network fees right into the quotes provided to users. Moreover, users are not limited to a singular liquidity source for their swaps; rather, the platform continues to aggregate information from a plethora of providers, which includes decentralized exchange aggregators, market makers, and various decentralized exchanges (DEXs), thus ensuring competitive rates and low network charges.
Currently, the Gas Station feature is accessible through the MetaMask Extension on the Ethereum mainnet, with future plans to roll it out on mobile devices as well. To utilize this function, the swap amount must not only cover gas costs but also include accepted assets such as USDT, USDC, DAI, ETH, wETH, wBTC, wstETH, and wSOL.

Another significant enhancement allows users to authorize transactions across any permitted network without the need to authorize network changes manually. This upgrade is made possible thanks to Chain Permission controls, which offer a finer level of control over account and network settings.
Permissions are assigned to each decentralized application (dApp) whenever a user connects, ensuring flexibility and oversight. When linking to a dApp, the current account and any default-enabled networks automatically receive permissions for that particular dApp. Users have the option to adjust these permissions at the time of initializing the connection or later via the 'All Permissions' segment. For those who operate their own systems, such as home stakers, this update also accommodates the reviewing and modifying of preferred RPC URLs.
