As a non-custodial wallet, MetaMask ensures that users retain full control of their private keys and digital assets, while seamlessly connecting to an expanding ecosystem of decentralized applications.

MetaMask Wallet Architecture
MetaMask encrypts user keys locally and requires seed phrases for wallet recovery. With smart contract-based smart accounts, additional modular functionality is introduced while maintaining the original externally owned account (EOA) and address.
Getting Started with MetaMask Wallet
- Download the MetaMask extension on your preferred crypto-compatible browser or the mobile app from official app stores.
- Create a new wallet or restore an existing one using your Secret Recovery Phrase or social login options.
- Set a strong password, enable two-factor authentication where applicable, and securely store your recovery phrase offline.
- Explore your wallet dashboard to send, receive, or swap tokens and interact with decentralized applications.
- For enhanced security, connect hardware wallets like Ledger or Trezor through MetaMask for offline key storage.
- Customize your wallet by adding multiple accounts and switching between supported blockchain networks effortlessly.
Understanding Fees and Transactions
MetaMask users pay Ethereum network gas fees, which have been optimized recently to average around $3.78 per transaction, down from historical highs. The wallet’s swap feature charges a transparent 0.875% fee in addition to gas costs. Future features aim to abstract gas fees, enabling payment in tokens other than ETH.
Security Best Practices
- Never share your Secret Recovery Phrase or private keys.
- Use hardware wallets for highest levels of security.
- Be cautious with dApp permissions; only approve interactions from trusted sources.
- Use social login cautiously, and always backup recovery keys offline.
- Regularly update MetaMask software to benefit from security patches and new features.
