dApp (Decentralized Application)
An application that runs on a blockchain instead of a company’s private servers.
A dApp — short for Decentralized Application — is an app built on a blockchain like Ethereum or Solana.
Unlike normal apps (run by companies on their servers), dApps are powered by smart contracts,
which means no single person or company controls them.
Popular examples include Uniswap, Aave, and OpenSea.
Why it matters
- Censorship-resistant — no one can shut it down.
- Transparent — all transactions and logic are visible on-chain.
- User-owned — you connect your own wallet, not an email or password.
How it works
- The dApp connects to your crypto wallet (like MetaMask).
- You approve actions via smart contracts.
- Results are recorded on the blockchain, not on company servers.
💡 Lanzo Tip
If you can connect your wallet instead of logging in with an email,
you’re likely using a dApp — part of the new, open Web3 world.
