Web2 Apps vs Web3 Apps
Web2 apps authenticate with accounts and store state on private servers; Web3 apps authenticate with a wallet signature and keep state on a public chain.
/ quick answer
The user-visible difference is login and ownership: a signature instead of a password, assets that stay with you when the frontend disappears.

Related concepts
The vocabulary this page depends on.
- →Web3 Wallet
A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.
- →Private Key
A private key is the secret number that authorises transactions from an address; the public address is derived from it, never the reverse.
- →Self-Custody
Self-custody means you control the private keys to your assets, so no company can freeze, lend out or lose them on your behalf.
- →Seed Phrase
A seed phrase is the 12–24 word backup from which every private key in a wallet is derived — whoever holds it holds the wallet.
