What Is DeFi

Rebuilding Financial Services Without Banks

What Is DeFi (Decentralized Finance)?

Decentralized Finance, commonly known as DeFi, refers to financial services built on blockchain technology without traditional banks or intermediaries.

Instead of relying on banks, brokers, or financial institutions, DeFi uses smart contracts to provide services such as:

  • Lending
  • Borrowing
  • Trading
  • Earning interest

All of this happens directly on blockchain networks.


How DeFi Works

DeFi applications operate through smart contracts on blockchains like Ethereum.

Here’s how it typically works:

1️⃣ A user connects a crypto wallet.
2️⃣ The user interacts with a decentralized application (DApp).
3️⃣ Smart contracts automatically execute transactions.
4️⃣ No bank or central authority is involved.

Everything is automated and transparent.
