Crypto wallet MetaMask now lets you swap tokens on your phone

MetaMask, one of the most popular web wallets for cryptocurrency platform Ethereum, went mobile on iOS and Android in September 2020. However, the mobile version wasn't updated at the same pace as the web version — in particular, the ability to exchange one crypto token for another, which went live on the web in October 2020, never made it to mobiles.

This changes today. The new version of MetaMask Mobile allows users to swap one token for another. To do this, open MetaMask on your phone and tap the new 'Swap' button, where you can choose the tokens you want to exchange, select a quote, and then swipe to perform a swap. Estimated fees for the swap are shown above the "Swipe to swap" button.

For this feature, MetaMask is using multiple DEXs (decentralized exchanges) and AMMs (automated market makers) to find the best price for a particular token. The company also says its calculations of gas prices (gas fees are fees for transactions on the Ethereum network, which dynamically change as a result of multiple factors, including network congestion) will result in reduced gas costs. Finally, MetaMask employs slippage protection, by spreading orders across multiple exchanges to reduce slippage costs.
