MetaMask has taken time to create a first-class EIP-1559 gas estimation that we expect to allow our users to have a great experience under any network conditions. EIP-1559 provides a way for users to avoid overpaying under normal conditions, and MetaMask's advanced mempool monitoring will help our users get transactions mined the fastest under volatile conditions, too.
