MetaMask customer support plays a critical role in assisting users with navigating issues related to its cryptocurrency wallet and decentralized application (dApp) browser. As a non-custodial wallet, MetaMask emphasizes user responsibility and security, which is reflected in its support structure. Instead of offering traditional phone or live chat services, MetaMask provides a comprehensive self-help portal at support.metamask.io, where users can find detailed guides, troubleshooting steps, and FAQs covering everything from wallet setup to transaction failures.
