MetaMask
MetaMask is a popular cryptocurrency wallet that supports a wide range of Ethereum-based tokens and non-fungible tokens (NFTs) on supported blockchains
The wallet can be downloaded as software or added as a browser extension, providing users with security, anonymity, and decentralization. MetaMask does not require users to disclose personal identifying data such as name, email, social security number, and address, and users can store their private keys. The wallet supports tokens on the ERC-20 protocol and NFTs that can be connected with marketplaces. The wallet also supports multiple blockchains including BNB chain, Polygon, and Avalanche. However, the wallet does not support Bitcoin.
MetaMask's approach to security is through anonymity and entrusting private keys to users. The wallet can be recovered via a 12-word mnemonic phrase, which users need to keep safe. The wallet is susceptible to hacks and malware, including phishing scams and other crypto scams.
MetaMask prioritizes anonymity, and users are not required to submit personal information. Transactions are classified as pseudonymous since transactions are recorded on the public blockchain, and the wallet ID acts as a pseudonym for the user.
MetaMask functions as an in-browser application for desktop or laptop computers and as a smartphone app available on the Google Play Store and Apple App Store. The wallet can be seamlessly integrated with various NFT marketplaces and dapps. Users can send or receive coins with any other wallet or smart contract provided a supported blockchain is used.
Transaction fees on MetaMask depend on users. They can customize their gas fees depending on the speed of transaction they prefer, and when buying crypto, users may be expected to pay a processing fee, a base fee, and a gas limit. Users will also pay a service fee of 0.875% for any swaps.
Even though MetaMask is one of the most popular cryptocurrency wallets in the Ethereum ecosystem, customer support is only available for technical problems when using the wallet on a personal device. Users can get help through the self-help center, the community message board, email, or the ticket system, even though support is not live.
