The Vibe: An app that runs on blockchain instead of a company’s servers—no single person or company controls it.
The Details: A dApp is like a normal app (website or mobile), but its backend code (smart contracts) lives on a blockchain, making it open, transparent, and resistant to shutdown or censorship. Anyone can use it by connecting a wallet—no sign-up or permission needed. Popular examples: Uniswap for swapping tokens, Aave for lending, or OpenSea for NFTs. You interact directly with the blockchain, so you keep full control of your money.
Pro Tip: Start with simple dApps on cheap Layer 2 networks (like Arbitrum or Base) to keep gas fees low. Always connect your wallet to official sites—fake dApp sites are common phishing scams.
