🚨As someone who has worked at an exchange for 6 years, let me explain the risk control measures in exchanges for beginners
01/ KYC: Know Your Customer
✅The platform collects detailed information about customers for analysis.
✅First, determine if the customer is a sensitive individual, such as those under international sanctions, terrorist organizations, political figures, etc. (Usually verified using third-party platform data, such as #Dowjones, #LexisNexis, and other list databases)
✅Classify customers based on risk levels (Risk Assessment) according to parameters such as country, occupation, sensitive individuals, etc.
✅Each risk level has different tolerances for using the exchange.
02/ KYT & KYA: Know Your Transactions and Wallet Assets
✅KYT & KYA are on-chain analysis tools that monitor transactions when the exchange interacts with on-chain addresses.
✅On-chain addresses are mixed, and can be categorized into black market, dark web, sanctioned addresses, hacker addresses, etc.
✅Generally, third-party databases are accessed to make judgments, such as @elliptic, @chainalysis, @SlowMist_Team, etc.
✅People engaging in over-the-counter trading should be very cautious about the source of the other party's wallet address, as they might be directly flagged by the exchange's risk control.
03/ Transaction Behavior Monitoring
✅Abnormal transaction monitoring: high-frequency small transactions, unusually large withdrawals, high-frequency cross-currency transactions.
✅Money laundering behavior monitoring: inflows and outflows in a short period, fund transfers between multiple accounts.
Each exchange operates dozens to hundreds of risk control rules.
✅Suspicious transaction reports: After hitting a risk control rule, an analysis is conducted, and if the transaction is deemed suspicious, it is reported to regulatory authorities.
04/ Market Manipulation
✅Account behavior monitoring: frequent two-way transactions, transaction times extremely close together, profit and loss deviating from normal logic.
✅Account correlation monitoring: multiple accounts using the same IP address/device fingerprint for trading, frequent interactions with on-chain addresses.
✅Order book monitoring: order book being deepened and then instantly withdrawn, unusual concentration of transaction volume.
05/ Market Maker Risk Control
✅Access and qualification review, such as background checks and agreement constraints, signing clear service agreements.
✅Transaction behavior monitoring: quoting standards, abnormal transaction monitoring, cancellation rate limits, trading volume requirements.
✅Funds and risk management: margin requirements, fund isolation, leverage limits, clearing mechanisms.
✅Market volatility response: circuit breaker mechanisms, dynamic adjustment of price spreads, liquidity guarantees, etc.
