What is DeFi? A Comprehensive Guide to Decentralized Finance

·

Key Takeaways


Understanding DeFi

Decentralized Finance (DeFi) refers to blockchain-based financial tools like lending platforms and decentralized exchanges. It merges finance with blockchain technology, enabling automated transactions through software.


Why DeFi Matters

Traditional banking relies on centralized control, leading to:

  1. Censorship risks: Governments can restrict financial access.
  2. Systemic failures: Banks may mismanage funds, preventing withdrawals.
  3. High fees: Disproportionate costs for underserved users.

DeFi solves these issues via smart contracts — self-executing code that enforces agreements transparently, enabling "programmable money" without intermediaries.


How DeFi Works: Smart Contracts in Action

Example: Securing a loan via DeFi:

  1. Deposit collateral into a protocol’s smart contract.
  2. Funds are automatically released upon meeting terms.
  3. Repayments can be automated via scheduled deductions from your 👉 crypto wallet.

Exploring DeFi Applications

1. Self-Custody Wallets (Phantom)

2. Decentralized Exchanges (DEXs)

Swap crypto peer-to-peer:

3. Borrowing & Lending (AAVE)

  1. Lend crypto: Earn APY by supplying assets (e.g., on Polygon).
  2. Borrow crypto: Use supplied funds as collateral.
  3. Automated safeguards: Loans auto-repay if collateral dips.
