Create Leverage
Use borrowed assets for further investments
Potential Liquidation
Forced selling if collateral value falls
Liquidity Creation Mechanisms
Overcollateralized Lending: Users deposit crypto, borrow stablecoins (net money creation)
Liquidity Mining: Protocols issue tokens to incentivize participation
Yield Farming: Complex strategies to maximize returns and create leverage
Liquidity Destruction Events
Liquidations: Forced selling when collateral values fall
Bank Runs: Mass withdrawals from lending protocols
Protocol Failures: Smart contract bugs or exploits
Comparison to Traditional Banking: Similar to fractional reserve banking but with different mechanics, more transparent but potentially more volatile, and no lender of last resort or deposit insurance.

Smart Contracts: The Building Blocks of DeFi
What are Smart Contracts
Self-executing contracts with terms directly written into code
Automatically enforce agreements without human intervention
Immutable once deployed (generally cannot be changed)
Transparent and auditable by anyone
Central Banking Analogy
Similar to how central bank policies are implemented through automated systems
Like having a payment system that operates according to pre-programmed rules
Difference: No central authority can override or modify the rules
Key Implications:
Financial services can operate without traditional intermediaries
Reduced operational risk but increased code risk
Transparency but also rigidity in operations

Single point of failure for many DeFi protocols
Price manipulation attacks through oracle exploitation
Centralization risk if few oracles dominate
Central Bank Relevance: Oracle failures can cause systemic DeFi disruptions, making them important for financial stability monitoring.
Token Standards and DeFi Economics
Key Token Standards
ERC-20: Fungible tokens (currencies, governance tokens)
ERC-721: Non-fungible tokens (NFTs, unique assets)
ERC-1155: Multi-token standard (gaming, complex assets)
Token Economics in DeFi
Governance Tokens: Voting rights in protocol decisions
Utility Tokens: Access to protocol features and services
Reward Tokens: Incentives for providing liquidity or using protocols
Economic Implications:
Tokens create new forms of ownership and governance
Token incentives drive user behavior and protocol adoption
Token values can be highly volatile and speculative
Central Bank Perspective: Token economics create new asset classes and investment behaviors that may affect broader financial markets.
Gas Fees and the Economics of Block Space
Gas Fee Mechanism
Users pay fees to execute transactions on blockchain
Fees vary based on network congestion and transaction complexity
Higher fees = faster transaction processing
Impact on DeFi Usage
High fees can make small transactions uneconomical
Fee volatility affects DeFi accessibility and adoption
Layer 2 solutions developed to reduce costs
Economic Implications:
Gas fees create natural usage limits and prioritization
Fee markets allocate scarce block space efficiently
High fees can exclude retail users from DeFi
Central Bank Consideration: Transaction costs affect DeFi's competitiveness with traditional payment systems and may influence adoption patterns.
Composability: The "Money Legos" of DeFi
Composability Concept
DeFi protocols can be combined like building blocks, one protocol's output becomes another's input, creating complex financial strategies and products.
Examples of Composability
Deposit in lending protocol → Use receipt token as collateral → Borrow stablecoins → Provide liquidity to DEX. Flash loans enable complex arbitrage and liquidation strategies. Yield aggregators automatically optimize across multiple protocols.
Benefits and Risks
Benefits: Innovation, efficiency, user choice. Risks: Complexity, interdependence, contagion potential.
Systemic Implications: Composability creates network effects but also systemic risks as protocols become interconnected.
What Could Go Wrong in Automated Finance?
Discussion Questions
What happens if a smart contract has a bug?
How do you handle disputes in automated systems?
What if the price data feeding the system is wrong?
Who is responsible when decentralized systems fail?
Risk Categories to Explore
Technical risks (code bugs, hacks)
Economic risks (market manipulation, liquidity crises)
Governance risks (protocol capture, bad decisions)
Systemic risks (contagion, cascading failures)
Decentralized Exchanges (DEXs): Automated Market Making
How DEXs Work
Automated Market Makers (AMMs): Mathematical formulas set prices
Liquidity Pools: Users provide tokens to enable trading
No Order Books: Prices determined by pool ratios and algorithms
Major DEX Protocols
Uniswap: Simple constant product formula (x*y=k)
Curve: Optimized for stablecoin and similar asset trading
Balancer: Multi-asset pools with customizable weights
Risks and Implications:
Impermanent Loss
Liquidity providers lose value during price volatility
Slippage
Large trades can significantly move prices
MEV (Maximal Extractable Value)
Sophisticated actors can extract value from transaction ordering
Uniswap
Decentralized Exchange Protocol
Uniswap is a fully decentralized on-chain protocol for token exchange on Ethereum that uses liquidity pools (AMM) instead of order books.
Liquidity Provision
Anyone can quickly swap between ETH and any ERC20 token or earn fees by supplying any amount of liquidity. And anyone can create a market (i.e., liquidity pool) by supplying an equal value of ETH and an ERC20 token.
Market Mechanism
Uniswap allows only one market per ERC20 token. The market creator sets the exchange rate, which shifts through trading due to Uniswap's "constant product market maker" mechanism. When trading reduces one side of the pair's liquidity relative to the other, the price changes. This creates arbitrage opportunities, encouraging more trading.
Lending and Borrowing Protocols: Banking Without Banks
Overcollateralization
Borrowers must deposit more value than they borrow

Pendle
Pendle lets you split future yield from your tokens into tradable components:
Your DeFi token (e.g., stETH, aUSDC) is split into:
Principal Token (PT) – the base value.
Yield Token (YT) – the future yield stream.
You can sell future yield now, buy discounted principal, or speculate on rate changes.
Cork Protocol
Flash Loans and MEV: Advanced DeFi Mechanics
Flash Loans
Uncollateralized loans that must be repaid within single transaction
Enable complex arbitrage and liquidation strategies
Can be used for both legitimate purposes and attacks
MEV (Maximal Extractable Value)
