๐Ÿ’ฐ DeFi Lending: Borrow & Earn Interest

Learn how Aave and Compound enable permissionless lending

๐Ÿฆ DeFi Lending & Borrowing

Decentralized lending and borrowing protocols allow you to earn interest on crypto assets or access liquidity without selling your holdingsโ€”all without traditional banks or credit checks.

What is DeFi Lending?

DeFi lending platforms connect lenders (who supply assets) with borrowers (who need liquidity) through smart contracts. Unlike traditional finance, everything is automated, permissionless, and transparent on the blockchain.

Key Innovation

No credit checks, no paperwork, no approval process. Smart contracts automatically execute loans based on collateral value. Anyone with a crypto wallet can participate globally.

  • โ€ข Withdraw anytime (instant liquidity)
  • โ€ข No lockup periods required
  • โ€ข Lower risk compared to other DeFi strategies
โš  Risks

How Does It Work?

๐Ÿ’Ž

For Lenders

  1. 1.Deposit assets into a lending pool (e.g., ETH, USDC)
  2. 2.Receive interest-bearing tokens (aTokens, cTokens)
  3. 3.Interest accrues automatically in real-time
  4. 4.Withdraw anytime (assets + earned interest)
๐ŸŽฏ

For Borrowers

  1. 1.Deposit collateral (must be >100% of loan value)
  2. 2.Borrow up to allowed limit (typically 50-75% of collateral)
  3. 3.Interest accrues continuously on borrowed amount
  4. 4.Repay loan + interest to unlock collateral
