What Is MyEtherWallet?
MyEtherWallet (MEW) is a widely popular Ethereum wallet launched in 2015. As a web-based service, MEW empowers users to securely store, send, and receive Ether (ETH) and ERC-20 tokens, as well as interact with smart contracts.
Unlike traditional wallets, MEW does not store your data. Instead, it generates a public address for receiving funds and a private key (a secret password) for authorizing transactions, putting you in full control of your assets.
Key Features:
- Self-custody: No third-party controls your private keys.
- ERC-20 support: Manage thousands of Ethereum-based tokens.
- Smart contract interaction: Ideal for ICOs and dApp users.
- User-friendly interface: Simple GUI for seamless navigation.
