Decentralized Finance (DeFi) is one of the biggest revolutions in crypto. It removes banks and middlemen, allowing you to trade, lend, borrow, and earn directly on the blockchain. Here’s everything beginners need to know.

πŸ”Ή 1. What is DeFi?

DeFi stands for Decentralized Finance. It’s a new financial system built on blockchains (like Ethereum, BNB Chain, Solana) where people interact with smart contracts instead of banks.

Simple words: DeFi = financial services without banks. You control your money using wallets + smart contracts.

πŸ”Ή 2. How DeFi Works

  • Smart contracts replace banks & intermediaries.
  • Users connect wallets like MetaMask or Trust Wallet. → Wallet Safety Tips
