Introduction
The decentralized finance (DeFi) ecosystem is powered by innovative protocols that enable:
- Permissionless lending and borrowing
- Efficient stablecoin trading
- Yield generation opportunities
- Trustless financial services
This guide explores three foundational DeFi protocols – Compound, Aave, and Curve – and their critical roles in the ecosystem.
1. Compound: Algorithmic Money Markets
Protocol Overview
- Launched: 2018
- TVL: ~$2B
- Native Token: COMP (governance)
Key Features
- Algorithmic interest rates
- cToken system (interest-bearing)
- Governance by COMP holders
- Permissionless asset listing
How It Works
- Users supply assets to pools
- Borrowers take loans against collateral
- Interest rates adjust automatically
- Lenders earn via cTokens
Use Cases
- Earning interest on idle crypto
- Borrowing against holdings
- COMP token governance
2. Aave: Advanced DeFi Lending
Protocol Overview
- Launched: 2020 (ETHLend rebrand)
- TVL: ~$6B
- Native Token: AAVE
Innovative Features
- Rate switching (stable/variable)
- aTokens (accrue interest)
- Flash loans
- Credit delegation
Unique Offerings
| Feature | Benefit |
|---|---|
| Flash Loans | No-collateral borrowing |
| Rate Switching | Optimize loan costs |
| Safety Module | Protocol insurance |
Aave V3 Upgrades

- Gas optimization
- Isolation mode
3. Curve Finance: Stablecoin Efficiency
Protocol Overview
- Launched: 2020
- TVL: ~$4B
- Native Token: CRV
Specialization
- Low-slippage stablecoin swaps
- Capital-efficient pools
- veCRV governance model
Technical Innovation
- Stableswap invariant algorithm
- Liquidity gauge system
- Metapools for asset composability
Major Pools
- 3pool (DAI/USDC/USDT)
- sUSD pool
- Ethereum staking derivatives
