How DeFi Works (Explained Simply)

1. Blockchain

The decentralized network that records all transactions securely and transparently.

2. Smart Contracts

Automated digital contracts that execute rules without human intervention.

Example:

“If a user deposits 1 ETH, pay 5% APY automatically.”

3. Decentralized Applications (DApps)

These are platforms that act like “decentralized banks,” offering financial services directly to users.

Popular DApps include:

Aave (borrowing & lending)

Uniswap (trading)

Curve (stablecoin swaps)

MakerDAO (stablecoin system)

Why DeFi Is Booming in 2025 (Especially in the US)
