DeFi Protocol Landscape

Decentralized Finance (DeFi) has evolved from experimental smart contracts to a $150B+ ecosystem offering every traditional financial service in a permissionless, transparent way. This guide covers the major protocol categories and how to use them.

How DEX (AMM) Works

Lending Protocols Explained

How Lending Works

  1. 1. Supply assets to earn interest
  2. 2. Borrow against your collateral
  3. 3. Maintain health factor above liquidation threshold
  4. 4. Repay loan anytime to unlock collateral

Key Metrics

  • LTV (Loan-to-Value): Max borrow % of collateral value
  • Liquidation Threshold: LTV where position gets liquidated
  • Utilization Rate: % of supplied assets being borrowed
  • Health Factor: Position safety ratio (must stay >1)

Liquid Staking

Liquid staking lets you stake ETH or SOL while receiving a liquid derivative token (stETH, jitoSOL) that can be used in DeFi. You earn staking rewards while maintaining capital efficiency.

Lido (stETH)
33.5M ETH staked
~3.2% APY
Rocket Pool (rETH)
1.1M ETH staked
~2.9% APY
Jito (jitoSOL)
14.2M SOL staked
~7.5% APY

Yield Optimization

Yield protocols help maximize returns through auto-compounding, boosting, or yield tokenization.

Pendle - Yield Trading

Splits yield-bearing tokens into Principal (PT) and Yield (YT) tokens. Lock in fixed yields or speculate on variable rates.

Yearn - Yield Vaults

Automated strategies that rotate capital across DeFi protocols to maximize yield while auto-compounding returns.

Convex - Curve Boosting

Maximizes Curve LP yields by aggregating veCRV voting power. Earn boosted CRV rewards without locking CRV yourself.

Understanding DeFi Risks

DeFi offers high yields but comes with significant risks. Understanding these is crucial before deploying capital.

DeFi Risk Assessment

Smart Contract RiskHigh

Bugs or vulnerabilities in protocol code can lead to loss of funds. Even audited protocols have been hacked.

Mitigation: Use battle-tested protocols, check audit reports, diversify across protocols

Impermanent LossMedium

LPs can lose value compared to holding when prices diverge. Worse in volatile pairs.

Mitigation: Use stable pairs, monitor IL, consider concentrated liquidity positions

Oracle ManipulationHigh

Attackers can manipulate price feeds to exploit lending and perpetual protocols.

Mitigation: Use protocols with decentralized oracles (Chainlink), avoid protocols with DEX-only price feeds

Governance RiskMedium

Token holders can vote to change protocol parameters, potentially harming users.

Mitigation: Monitor governance proposals, understand timelock periods

Liquidity RiskMedium

Low liquidity can cause slippage or prevent withdrawals during market stress.

Mitigation: Check TVL trends, avoid protocols with declining liquidity

Regulatory RiskLow

Regulations could restrict access to protocols or affect token values.

Mitigation: Understand jurisdiction, use decentralized frontends
