What is MetaMask?
MetaMask is a digital wallet and gateway facilitating seamless interaction with blockchain applications. Trusted by over 100 million users globally, it is available as a browser extension and a mobile app. MetaMask provides users with essential features like a key vault, secure login, and token exchange, offering an all-in-one solution for managing digital assets.
Uniquely focused on user-centric privacy and control, MetaMask generates cryptographic keys on-device, safeguarding access to your accounts and assets. It is compatible with various blockchain networks, including Ethereum, Polygon, zkSync and Arbitrum, among others.

What Chains Does MetaMask Support?
MetaMask is designed to support any blockchain compatible with the Ethereum Virtual Machine (EVM), whether a Layer 1 or Layer 2 solution. This compatibility ensures users can interact with various decentralized applications and protocols without switching between multiple wallets.
In addition to EVM compatibility, MetaMask has rolled out MetaMask Snaps, an extension framework.

Has MetaMask Been Exploited?
MetaMask itself has not been directly exploited due to vulnerabilities in its code. However, it's important to note that users of MetaMask have been targeted through phishing attacks and scams that aim to compromise private keys or trick users into authorizing malicious transactions. These incidents are generally due to user error or external malicious actors, rather than inherent vulnerabilities within MetaMask's software.
MetaMask users must practice vigilant security measures, such as keeping their seed phrases secure and double-checking website URLs to ensure they are not phishing sites. Security is a shared responsibility, and while MetaMask employs robust measures to protect your assets, users must also take steps to safeguard their information.
Fees and Costs
MetaMask doesn't charge fees for basic transactions, but you will incur network "gas fees" payable to Ethereum miners when sending tokens or using smart contracts. These fees fluctuate based on network congestion and are separate from MetaMask.
The MetaMask Swaps feature does include a 0.875% service fee for each token trade you execute within the wallet. This fee helps support the service's maintenance and development. The Swaps feature aims to find the best prices across multiple decentralized exchanges and liquidity providers while considering gas fees and slippage. Always be aware of all fees when using MetaMask.

MetaMask Token
MetaMask does not have its native token. While the wallet supports a variety of ERC-20 tokens and other blockchain assets, it has not issued a specific MetaMask token. Users should be cautious of any claims of a MetaMask airdrop or otherwise to avoid scams. Always rely on official sources for the most accurate and up-to-date information.
Bottom Line
In summary, MetaMask is a trusted digital wallet with a user-focused design, offering both basic and advanced features for asset management. Its compatibility with any EVM-compatible blockchain and extension to non-EVM networks through Snaps make it versatile and future-ready. Operated by ConsenSys, it caters to both individual and institutional needs, bridging the gap between traditional and decentralized finance.
