🕑 ~1.5 hours 📖 5 Sections 📈 Market Infrastructure

5.1 Centralized Exchanges (CEX)

Centralized exchanges remain the primary gateway for most crypto users. They offer familiar trading interfaces, fiat on-ramps, and high liquidity - but require users to trust the exchange with custody of their assets.

Centralized Exchange (CEX)
A trading platform operated by a company that matches buy and sell orders, holds user funds in custody, and typically requires KYC verification. Examples: Binance, Coinbase, Kraken.

CEX Architecture

  1. Order book: Central limit order book (CLOB) matching engine
  2. Hot wallets: Online wallets for immediate withdrawals (~5-10% of assets)
  3. Cold storage: Offline wallets for the majority of assets (~90-95%)
  4. Trading engine: High-performance matching system (millions of orders/second)
  5. KYC/AML: Identity verification and compliance systems

Major Centralized Exchanges

Exchange Headquarters Daily Volume Key Features
Binance Multiple jurisdictions ~$15-25B Largest by volume, BNB ecosystem
Coinbase USA (NASDAQ listed) ~$2-5B Regulated, institutional focus
Kraken USA ~$1-2B Security reputation, proof of reserves
OKX Seychelles ~$3-5B Derivatives, Web3 wallet
Bybit Dubai ~$5-10B Derivatives focus

Indian Exchange Landscape

  • WazirX: Largest Indian exchange, Binance-affiliated (ownership dispute)
  • CoinDCX: SEBI-compliant aspirations, institutional services
  • ZebPay: One of the oldest Indian exchanges
  • CoinSwitch: Retail-focused, large user base
⚠ Indian Regulatory Uncertainty

Indian exchanges operate without specific licensing framework. The 2022 tax regime legitimized trading but didn't establish exchange regulation. Users face counterparty risk and should limit exchange exposure to active trading needs only.

CEX Risks

Custodial Risk

  • Exchange holds your private keys
  • "Not your keys, not your coins"
  • Bankruptcy = potential loss (FTX)
  • Commingling of funds possible

Security Risk

  • Large honeypot for hackers
  • Mt. Gox: $470M stolen (2014)
  • Insider threats
  • Hot wallet compromises

Regulatory Risk

  • Account freezes
  • Withdrawal restrictions
  • Sudden jurisdiction exits
  • Asset delistings

5.2 Decentralized Exchanges (DEX)

Decentralized exchanges eliminate the trusted intermediary by executing trades through smart contracts. Users retain custody of their assets throughout the trading process - connecting directly from their wallets.

Decentralized Exchange (DEX)
A non-custodial trading platform built on smart contracts. Users trade directly from their wallets without depositing funds with a third party. No KYC required in most cases.

DEX vs CEX Comparison

Feature CEX DEX
Custody Exchange holds funds User retains custody
KYC Required Not required
Fiat support Yes No (crypto only)
Liquidity Higher Lower (varies)
Speed Instant Block confirmation time
Fees 0.1-0.5% 0.3% + gas fees
Privacy KYC data collected Wallet address only

Major DEX Platforms

DEX Chain(s) TVL Model
Uniswap Ethereum, Arbitrum, Polygon ~$5B AMM (Constant Product)
Curve Multi-chain ~$2B AMM (Stable Swap)
PancakeSwap BNB Chain, Ethereum ~$2B AMM (Uniswap fork)
dYdX Own chain (Cosmos) ~$500M Order book (derivatives)
Raydium Solana ~$200M AMM + Order book
⚡ DEX Aggregators

Aggregators like 1inch and Paraswap route trades across multiple DEXes to find the best price. They split large orders across pools to minimize slippage. Always compare aggregator quotes before large trades.

5.3 Automated Market Makers (AMMs)

AMMs replaced traditional order books with algorithmic pricing. Instead of matching buyers and sellers, traders swap against liquidity pools governed by mathematical formulas. This innovation enabled permissionless market making.

Automated Market Maker (AMM)
A smart contract that holds reserves of two or more tokens and allows trading against those reserves at algorithmically determined prices. Liquidity providers deposit tokens and earn fees from trades.

Constant Product Formula (x * y = k)

Uniswap pioneered the constant product formula, where the product of reserves must remain constant:

// Uniswap V2 Constant Product Formula

Reserve ETH (x) = 100 ETH
Reserve USDC (y) = 200,000 USDC
Constant (k) = x * y = 20,000,000

// User wants to buy 10 ETH
New ETH reserve = 90 ETH
New USDC reserve = k / 90 = 222,222 USDC
USDC paid = 222,222 - 200,000 = 22,222 USDC

// Effective price: 2,222 USDC/ETH (vs 2,000 spot)
// Slippage: ~11% for this large trade

Liquidity Provider (LP) Economics

  1. Deposit: LP deposits equal value of both tokens (e.g., $1000 ETH + $1000 USDC)
  2. Receive LP tokens: Represents share of pool
  3. Earn fees: 0.3% of each trade distributed pro-rata
  4. Impermanent loss: Portfolio divergence vs holding
  5. Withdraw: Burn LP tokens to receive underlying assets
⚠ Impermanent Loss

If token prices diverge significantly, LPs may have less value than simply holding. Called "impermanent" because loss only realizes on withdrawal. For volatile pairs, impermanent loss can exceed fee income.

AMM Variants

Uniswap V3

  • Concentrated liquidity
  • LPs choose price ranges
  • Higher capital efficiency
  • More complex management

Curve (StableSwap)

  • Optimized for similar assets
  • Much lower slippage
  • Ideal for stablecoin swaps
  • USDC/USDT/DAI pools

Balancer

  • Multi-token pools (up to 8)
  • Custom weightings (80/20)
  • Self-rebalancing portfolios
  • Smart order routing

5.4 Trading Mechanics

Understanding order types, market structure, and execution is essential for effective trading and advising clients. Crypto markets operate 24/7 with unique characteristics compared to traditional finance.

Order Types

Order Type Execution Use Case
Market Order Immediate at best available price Urgent execution, small orders
Limit Order Only at specified price or better Price-sensitive execution
Stop-Loss Market order when price reaches trigger Risk management
Stop-Limit Limit order when price reaches trigger Controlled exit
OCO (One-Cancels-Other) Paired orders - one executes, other cancels Take-profit + stop-loss combo

Market Microstructure

  • Spread: Difference between best bid and ask prices
  • Depth: Volume available at various price levels
  • Slippage: Price movement during order execution
  • Maker/Taker: Makers add liquidity (limit orders), takers remove it (market orders)

Derivatives Trading

Perpetual Futures (Perps)
Futures contracts with no expiry date. Price tracked to spot via funding rate mechanism - longs pay shorts (or vice versa) every 8 hours based on premium/discount to spot price.
  • Leverage: Up to 100x on some platforms (extremely risky)
  • Funding rate: Keeps perp price aligned with spot
  • Liquidation: Position closed if margin insufficient
  • Insurance fund: Covers liquidation shortfalls
⚠ Leverage Warning

High leverage amplifies both gains and losses. At 100x, a 1% price move against your position results in 100% loss. Most retail traders lose money on leveraged trading. Never risk more than you can afford to lose.

5.5 Exchange Security & Hacks

Exchange hacks have resulted in billions of dollars in losses. Understanding common attack vectors and security practices is essential for advising clients and conducting due diligence on exchange selection.

Major Exchange Hacks

Exchange Year Loss Attack Vector
Mt. Gox 2014 $470M Hot wallet theft (ongoing over years)
Bitfinex 2016 $72M Multi-sig compromise
Coincheck 2018 $530M Hot wallet (NEM tokens)
Binance 2019 $40M API keys, 2FA codes phished
FTX 2022 $8B+ Internal fraud, misappropriation
WazirX 2024 $235M Multi-sig wallet compromise

Security Best Practices

For Users

  • Hardware 2FA (YubiKey), not SMS
  • Unique, strong passwords
  • Withdrawal address whitelist
  • Minimize exchange balances
  • Enable all security features

Exchange Evaluation

  • Proof of Reserves audits
  • Insurance fund size
  • Cold storage percentage
  • Security incident history
  • Regulatory compliance

Proof of Reserves

After FTX collapse, proof of reserves became an industry standard:

  • Merkle tree: Cryptographic proof user balances are included
  • On-chain verification: Public addresses showing reserve holdings
  • Third-party attestation: Accounting firm verification
  • Limitations: Doesn't show liabilities or encumbrances
✔ Due Diligence Checklist

Before recommending or using an exchange: (1) Check proof of reserves, (2) Review security history, (3) Verify regulatory status, (4) Check insurance fund, (5) Review withdrawal policies. Prefer regulated exchanges for large holdings.

Key Takeaways

  • CEXs offer convenience but custody risk - "not your keys, not your coins"
  • DEXs provide non-custodial trading via smart contracts but have lower liquidity
  • AMMs use mathematical formulas (x*y=k) instead of order books
  • Impermanent loss affects liquidity providers when token prices diverge
  • Perpetual futures use funding rates to track spot prices without expiry
  • Exchange hacks have stolen billions - Mt. Gox, FTX, WazirX examples
  • Proof of reserves emerged post-FTX but doesn't show liabilities
  • Indian exchanges lack regulatory framework - use caution and minimize exposure
