🔎 What Is KYT on Crypto Exchanges?
KYT (Know Your Transaction) is a compliance practice that involves real‑time monitoring and analysis of transactions on a blockchain to detect suspicious activity, assess risk, and ensure compliance with AML/CTF regulations. Unlike KYC (Know Your Customer), which focuses on who the customer is, KYT focuses on what the customer does with their funds — the source, destination, and patterns of their transactions.
KYT uses blockchain analytics to map the flow of funds across the blockchain, identify interactions with known illicit addresses (e.g., darknet markets, ransomware wallets, sanctioned entities), and assign risk scores to transactions and counterparties. This enables exchanges to comply with regulatory obligations such as the Travel Rule, filing Suspicious Activity Reports (SARs), and maintaining a robust transaction monitoring program.
KYT is the operational backbone of AML compliance for exchanges. It provides the visibility needed to detect money laundering, terrorist financing, and sanctions evasion in real time. Without KYT, exchanges are blind to the risk of the transactions they process.
⚖️ KYT vs. KYC: Understanding the Difference
While KYC and KYT are often mentioned together, they serve different but complementary purposes in an exchange's compliance framework.
| Feature | KYC (Know Your Customer) | KYT (Know Your Transaction) |
|---|---|---|
| Focus | Identity of the customer | Transaction flow and risk |
| When It Happens | Customer onboarding and periodic updates | Real‑time and ongoing |
| What It Checks | Name, address, ID, proof of address, source of funds | Origin and destination of funds, address risk, transaction patterns |
| Tools Used | ID verification, liveness checks, document OCR | Blockchain analytics, risk scoring, clustering algorithms |
| Primary Output | Customer risk profile, KYC status | Transaction risk alerts, SARs, Travel Rule data |
| Regulatory Driver | AML/CTF, customer identification requirements | Travel Rule, transaction monitoring, SAR filing |
KYC and KYT are two sides of the same coin. KYC tells you who your customer is; KYT tells you what they are doing with their funds. Both are required for a comprehensive AML program.
⚙️ How KYT Works: The Technology Behind It
KYT relies on sophisticated blockchain analytics and risk assessment technologies. Here's how it works in practice.
- Blockchain Data Ingestion: The KYT system continuously ingests blockchain data (transactions, addresses, blocks) from the networks the exchange supports.
- Address Clustering: Algorithms group addresses into clusters based on transaction patterns, identifying wallets controlled by the same entity.
- Risk Tagging: Addresses are tagged with risk categories based on their known activity (e.g., exchange, mixer, darknet market, ransomware, sanctioned entity).
- Transaction Scoring: Each transaction is assigned a risk score based on the risk of the source and destination addresses, the amount, and other factors.
- Rule‑Based Alerts: Automated rules trigger alerts for transactions that exceed risk thresholds or match specific patterns (e.g., large transfers to high‑risk jurisdictions).
- Case Management: Compliance analysts review alerts, investigate suspicious activity, and decide whether to file a SAR.
- Travel Rule Compliance: KYT systems help identify transactions that trigger the Travel Rule and facilitate the exchange of required information with counterparties.
Risk scoring is the core of KYT. Scores are typically on a scale of 0–100, with higher scores indicating higher risk. Factors include: address risk tags, transaction amount, speed of funds movement, geographic risk, and deviation from normal behavior.
🧩 Key Components of a KYT Program
A comprehensive KYT program on an exchange includes several interconnected components.
Real‑time analysis of blockchain data to identify transaction patterns, address clusters, and risk associations.
Quantitative assessment of transaction risk based on source, destination, amount, and other factors.
Automated alerts for transactions that exceed risk thresholds or match suspicious patterns.
Case management and investigation capabilities for compliance analysts to review alerts and take action.
Automated generation of reports for regulators, including SARs and Travel Rule data.
Advanced analytics that improve risk detection over time by learning from past patterns and investigations.
KYT works best when integrated with KYC data. Combining customer identity information with transaction risk data provides a complete picture of customer behavior and enables more effective risk management.
✈️ KYT and the Travel Rule
The Travel Rule (FATF Recommendation 16) requires exchanges to collect and share originator and beneficiary information for crypto transfers above a certain threshold. KYT plays a crucial role in Travel Rule compliance.
- Threshold Detection: KYT systems identify transactions that exceed the Travel Rule threshold (typically €1,000 or $3,000).
- Information Collection: The system collects the required originator and beneficiary information from the customer's KYC data.
- Information Transmission: The data is securely transmitted to the receiving exchange or wallet provider using protocols like TRISA or OpenVASP.
- Recordkeeping: Records of Travel Rule data transfers are retained for audit and regulatory review.
Implementing the Travel Rule is one of the most challenging aspects of KYT. Exchanges should use dedicated Travel Rule solutions that integrate with their KYT platform to automate the process and ensure compliance.
🚩 Identifying Suspicious Transactions with KYT
KYT helps exchanges detect a wide range of suspicious activities. Common red flags include:
- Structuring / Smurfing: Multiple small transactions that appear designed to avoid reporting thresholds.
- High‑Risk Counterparties: Transactions involving addresses tagged as mixers, darknet markets, or sanctioned entities.
- Rapid In‑and‑Out Transfers: Funds that are deposited and withdrawn quickly without any trading activity.
- Unusual Volume: Transactions that are significantly larger than the customer's normal activity.
- Geographic Risk: Transactions involving jurisdictions with known money laundering risks or sanctions.
- Circular Transfers: Funds that move through multiple wallets and return to the originator.
- No Economic Purpose: Transactions that appear to have no clear business or personal rationale.
🛠️ Implementing KYT on Your Exchange
A successful KYT implementation requires a combination of technology, processes, and people.
