TL;DR
MetaMask has integrated Across. Swap and bridge tokens between major chains directly inside MetaMask, which automatically chooses the best route amongst 18 swap and bridge providers; Across powers selected routes when most optimal. As a developer, you can add the same native crosschain functionality in your own wallet or app using the Across Swap API.
Introduction
Let’s be honest. You probably open MetaMask more often than your email.
It is where you check your balances, sign transactions, and jump into whatever is happening onchain. You can even swap tokens between chains quickly, affordably, and safely, without ever leaving homebase.
Across is now one of the providers powering swap and bridge in MetaMask.
