What Is Web3?
Web3 signifies the shift toward a decentralized internet, empowering users with control over their data, identities, and assets via blockchain technology. Central to this ecosystem is the Web3 wallet—a secure, self-custodial tool for managing digital assets like cryptocurrencies, NFTs, and tokenized rewards without intermediaries.
Definition: Web3 Wallet
A Web3 wallet is a digital application (mobile, browser extension, desktop, or hardware device) enabling users to:
- Store and transfer assets (crypto, NFTs, tokens)
