Crypto Exchange

What Is a Crypto Exchange?

Buying, selling, and trading cryptocurrency requires a marketplace. That marketplace is a crypto exchange.

A crypto exchange is a platform that enables users to buy, sell, and trade digital assets. It connects buyers and sellers, provides pricing based on market activity, and facilitates the settlement of transactions. For most people, a crypto exchange is the first and primary point of contact with the crypto ecosystem.

Types of Crypto Exchanges

Centralized Exchanges (CEX)

Centralized exchanges are operated by a company that acts as an intermediary between buyers and sellers. Users create accounts, complete KYC verification, and trust the platform to hold and manage their funds. Popular examples include Binance, Coinbase, Kraken, and OKX.

Key characteristics:

• High liquidity and trading volume
• User-friendly interfaces
• Custodial wallets where the exchange holds private keys
• Subject to regulatory oversight and licensing requirements

Decentralized Exchanges (DEX)

Decentralized exchanges operate without a central authority. Trades happen directly between users through smart contracts on the blockchain. No account registration or KYC is required in most cases. Popular examples include Uniswap, PancakeSwap, and dYdX.

Key characteristics:

• Non-custodial, users retain control of their private keys
• Greater privacy but lower liquidity compared to CEXs
• Governed by smart contracts and community governance
• Growing regulatory scrutiny globally

Hybrid Exchanges

Hybrid exchanges combine elements of both CEX and DEX, offering centralized liquidity with decentralized custody and settlement. They aim to deliver the best of both models.

How a Crypto Exchange Works

The core function of any exchange is matching buyers with sellers at an agreed price. This happens through an order book or an automated market maker (AMM) model.

• Order book model used by most CEXs, where buy and sell orders are listed and matched when prices align
• AMM model used by DEXs, where liquidity pools replace traditional order books and prices are determined algorithmically

Once a trade is matched, settlement occurs either internally within the exchange's system or directly on-chain depending on the platform type.

Crypto Exchanges and Regulatory Obligations

Crypto exchanges sit at the center of regulatory attention globally. As primary gateways for fiat-to-crypto and crypto-to-crypto activity, they carry significant compliance responsibilities:

• KYC (Know Your Customer) verification for all users before trading
• AML (Anti-Money Laundering) transaction monitoring to detect suspicious activity
• Sanctions screening of user accounts and wallet addresses against global watchlists
• Travel Rule compliance for transferring sender and receiver information on qualifying transactions
• SAR filing when suspicious activity is identified
• Licensing and registration in every jurisdiction where they operate

Regulatory frameworks such as FATF guidelines, MiCA in Europe, FinCEN requirements in the United States, and FCA rules in the United Kingdom all place direct obligations on crypto exchanges to operate as responsible financial gatekeepers.

Key Compliance Risks for Crypto Exchanges

Exchanges face a range of financial crime risks that require constant vigilance:

• Onboarding users linked to sanctioned entities or high-risk jurisdictions
• Processing deposits or withdrawals from wallets connected to darknet markets, ransomware, or fraud schemes
• Being used as layering vehicles in money laundering schemes
• Facilitating transfers that breach Travel Rule thresholds without proper information sharing
