5.6.1: What are DeFi Derivatives? – The Complete Picture
Definition and Core Concepts
Derivatives are financial contracts whose value depends on an underlying asset, index, or benchmark. DeFi derivatives bring these instruments on-chain, enabling permissionless trading, hedging, and speculation.
Traditional vs DeFi Derivatives: Traditional Derivatives (CeFi): ┌─────────────────────────────────────────────────────────────────────┐ │ Characteristics: │ │ • Centralized exchanges (CME, CBOE) │ │ • Regulated brokers │ │ • Fiat settlement │ │ • Limited access │ │ • High minimums │ └─────────────────────────────────────────────────────────────────────┘ DeFi Derivatives: ┌─────────────────────────────────────────────────────────────────────┐ │ Characteristics: │ │ • Decentralized exchanges (dYdX, GMX) │ │ • Smart contract execution │ │ • Crypto settlement │ │ • Permissionless access │ │ • Low minimums (0.1 ETH) │ └─────────────────────────────────────────────────────────────────────┘
Why Derivatives Matter in DeFi:
Derivatives Use Cases: 1. Hedging: ┌─────────────────────────────────────────────────────────────┐ │ • Protect against price drops │ │ • Lock in profits │ │ • Reduce portfolio risk │ └─────────────────────────────────────────────────────────────┘ 2. Speculation: ┌─────────────────────────────────────────────────────────────┐ │ • Leveraged directional bets │ │ • Profit from price movements │ │ • Access to new markets │ └─────────────────────────────────────────────────────────────┘ 3. Arbitrage: ┌─────────────────────────────────────────────────────────────┐ │ • Profit from price differences │ │ • Risk-free returns │ │ • Market efficiency │ └─────────────────────────────────────────────────────────────┘ 4. Price Discovery: ┌─────────────────────────────────────────────────────────────┐ │ • Efficient price formation │ │ • Market sentiment │ │ • Future price expectations │ └─────────────────────────────────────────────────────────────┘
5.6.2: Perpetual Contracts – The Most Popular Derivative
What are Perpetuals?
Perpetual contracts (perpetuals) are derivative instruments that track the price of an underlying asset without an expiry date. They are the most popular DeFi derivative.
Perpetual Contract Characteristics: ┌─────────────────────────────────────────────────────────────────────┐ │ Perpetual Contract │ │ │ │ No Expiry: │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Never expires │ │ │ │ • Can hold indefinitely │ │ │ │ • No settlement date │ │ │ └─────────────────────────────────────────────────────────────┘ │ │ │ │ Leverage: │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • 1x to 100x leverage │ │ │ │ • Amplified profits and losses │ │ │ │ • Margin requirement │ │ │ └─────────────────────────────────────────────────────────────┘ │ │ │ │ Funding Rate: │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Periodic payments between longs and shorts │ │ │ │ • Keeps price aligned with spot │ │ │ │ • 8-hour intervals │ │ │ └─────────────────────────────────────────────────────────────┘ │ │ │ │ Long/Short: │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Long: Bet on price increase │ │ │ │ • Short: Bet on price decrease │ │ │ │ • Can profit in both directions │ │ │ └─────────────────────────────────────────────────────────────┘ │ └─────────────────────────────────────────────────────────────────────┘
Funding Rate Mechanics:
The funding rate ensures the perpetual price stays close to the spot price.
Funding Rate Formula: Funding Rate = (Mark_Price - Index_Price) / Index_Price + Interest_Rate Components: 1. Premium: Difference between mark and index price 2. Interest: Base rate (usually 0.01%) If Mark_Price > Index_Price (Bullish): - Longs pay shorts - Incentivizes shorts to enter - Pushes price down If Mark_Price < Index_Price (Bearish): - Shorts pay longs - Incentivizes longs to enter - Pushes price up Example Calculation: Index Price: $3,000 Mark Price: $3,030 Premium: 1% (30/3000) Interest: 0.01% (0.0001) Funding Rate = 0.01 + 0.0001 = 0.0101 (1.01%) Payment (Long Position, 1 ETH): - 1.01% × 1 ETH = 0.0101 ETH paid to shorts - 8-hour payment cycle Funding Rate History: - Positive: Longs pay shorts (bullish) - Negative: Shorts pay longs (bearish) - Typically 0.01-0.10% per 8 hours
Leverage and Margin:
Leverage Mechanics: Position Size = Margin × Leverage Example: - Margin: 1 ETH ($3,000) - Leverage: 10x - Position Size: 10 ETH ($30,000) Price Change Impact: - 1% Price Increase: 10% Profit - 1% Price Decrease: 10% Loss - 10% Price Decrease: 100% Loss (Liquidation) Margin Requirements: - Initial Margin: 1/leverage - Maintenance Margin: 0.5-1% - Liquidation: When margin falls below maintenance Liquidation Price: Long Position: Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance/2) Short Position: Liquidation Price = Entry Price × (1 + 1/Leverage - Maintenance/2) Example (Long, 10x Leverage): Entry: $3,000 Liquidation: $3,000 × (1 - 0.10 + 0.005) = $2,715
5.6.3: Options – The Right, Not the Obligation
Option Basics:
Options give the holder the right, but not the obligation, to buy or sell an asset at a predetermined price before a specific date.
Option Types: ┌─────────────────────────────────────────────────────────────────────┐ │ Call Option │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ Right to BUY at strike price │ │ │ │ Profits if price goes UP │ │ │ │ Pay premium (cost) │ │ │ └─────────────────────────────────────────────────────────────┘ │ ┌─────────────────────────────────────────────────────────────────────┐ │ Put Option │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ Right to SELL at strike price │ │ │ │ Profits if price goes DOWN │ │ │ │ Pay premium (cost) │ │ │ └─────────────────────────────────────────────────────────────┘ │ ┌─────────────────────────────────────────────────────────────────────┐ │ Option Styles │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ European: Exercise only at expiry │ │ │ │ American: Exercise anytime before expiry │ │ │ │ Most DeFi options: European (simpler) │ │ │ └─────────────────────────────────────────────────────────────┘ │
Option Pricing – The Black-Scholes Model:
The Black-Scholes model is the standard for pricing European options.
Black-Scholes Formula: C = S × N(d₁) - K × e^(-rt) × N(d₂) Where: C = Call Option Price S = Current Asset Price K = Strike Price r = Risk-Free Rate t = Time to Expiry σ = Volatility d₁ = (ln(S/K) + (r + σ²/2) × t) / (σ × √t) d₂ = d₁ - σ × √t Put Option Price: P = K × e^(-rt) × N(-d₂) - S × N(-d₁) Example (ETH Option): S = $3,000 K = $3,200 t = 30 days (0.082 years) σ = 80% r = 5% d₁ = (ln(3000/3200) + (0.05 + 0.64/2) × 0.082) / (0.8 × √0.082) d₁ = (-0.0645 + 0.0305) / 0.229 d₁ = -0.148 d₂ = -0.148 - 0.229 = -0.377 N(d₁) = 0.441 N(d₂) = 0.353 Call Price = 3000 × 0.441 - 3200 × e^(-0.0041) × 0.353 Call Price = 1323 - 1126 = $197
Option Strategies:
| Strategy | Setup | Direction | Risk/Reward |
|---|---|---|---|
| Long Call | Buy Call | Bullish | Limited loss (premium) |
| Long Put | Buy Put | Bearish | Limited loss (premium) |
| Covered Call | Hold asset + Sell Call | Neutral | Limited upside |
| Protective Put | Hold asset + Buy Put | Bullish | Protects downside |
| Straddle | Buy Call + Buy Put | Volatile | High cost |
| Spread | Buy + Sell Options | Various | Limited risk/reward |
5.6.4: Synthetic Assets
What are Synthetics?
Synthetic assets are tokenized derivatives that track the price of real-world assets without holding the underlying.
Synthetic Asset Examples: ┌─────────────────────────────────────────────────────────────────────┐ │ Synthetic Assets │ │ │ │ sUSD: Synthetic USD │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Tracks USD price │ │ │ │ • Collateral: SNX tokens │ │ │ │ • No underlying USD needed │ │ │ └─────────────────────────────────────────────────────────────┘ │ │ │ │ sETH: Synthetic ETH │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Tracks ETH price │ │ │ │ • Collateral: SNX tokens │ │ │ │ • No underlying ETH needed │ │ │ └─────────────────────────────────────────────────────────────┘ │ │ │ │ sBTC: Synthetic Bitcoin │ │ ┌─────────────────────────────────────────────────────────────┐ │ │ │ • Tracks BTC price │ │ │ │ • Collateral: SNX tokens │ │ │ │ • No underlying BTC needed │ │ │ └─────────────────────────────────────────────────────────────┘ │ └─────────────────────────────────────────────────────────────────────┘

1. Perpetual Contract Math
Perpetual Contract Value: P = S × (1 + r × t) + f Where: P = Perpetual Price S = Spot Price r = Funding Rate t = Time to Next Funding f = Premium/Discount Mark Price Calculation: Mark Price = Index Price + (Premium × K) Where K = 0.01 (smoothing factor) Liquidation Calculation: Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance/2)
2. Option Greeks
Option Greeks: 1. Delta (Δ): Rate of change of option price with underlying Δ = N(d₁) for calls Δ = N(d₁) - 1 for puts 2. Gamma (Γ): Rate of change of delta Γ = N'(d₁) / (S × σ × √t) 3. Vega (V): Sensitivity to volatility V = S × N'(d₁) × √t 4. Theta (Θ): Time decay Θ = -(S × N'(d₁) × σ)/(2√t) - r × K × e^(-rt) × N(d₂) 5. Rho (ρ): Sensitivity to interest rate ρ = K × t × e^(-rt) × N(d₂)
