Web3 Wallet is a digital wallet used to interact with decentralized applications (dApps) and blockchain networks. Unlike traditional cryptocurrency wallets, Web3 Wallets are not only used for storing cryptocurrencies but also provide functionality to interact with decentralized finance (DeFi), non-fungible tokens (NFTs), decentralized exchanges (DEX), and other blockchain applications.
Wallet Features#
1. Non-custodial: Users have complete control over the assets in the wallet as they own the private keys. Wallet providers cannot access user funds.
2. Access to decentralized applications: Web3 Wallets typically integrate a dApp browser, allowing direct access and usage of various decentralized applications such as DeFi platforms, NFT markets, etc.
3. Support for multiple blockchain networks: Many Web3 Wallets support multiple blockchain networks like Ethereum, Binance Smart Chain, Polygon, enabling users to freely switch between and manage assets on different networks.
4. Smart contract interactions: Users can interact directly with smart contracts through the wallet, such as token swaps, providing liquidity, participating in lending, etc.
5. Identity verification and security: Web3 Wallets usually use methods like mnemonic phrases, passwords, hardware wallets for identity verification to ensure the security of user assets.
