As the cryptocurrency industry matures, regulatory scrutiny increases rapidly. Virtual Asset Service Providers (VASPs) are mandated to adhere to global Anti-Money Laundering (AML) and Counter-Terrorist Financing (CTF) regulations. Two critical, yet distinct, components of this necessary compliance framework are Know Your Customer (KYC) and Know Your Transaction (KYT).
Know Your Customer (KYC): Verifying Identity
KYC is the fundamental process of verifying the identity of a platform’s users. It focuses on collecting and validating personal information to ensure the customer is who they claim to be, mitigating the risk of anonymous fraudulent accounts, and establishing a baseline for user accountability.
Key elements gathered during the KYC process typically include:
- Government-issued identification (ID, passport, driver’s license)
- Proof of address (utility bills, bank statements)
- Facial recognition or liveness checks
- Screening against global sanctions lists and Politically Exposed Persons (PEPs) databases
KYC is typically a one-time or periodic event performed during account creation or when users reach specific transaction volume thresholds.
Know Your Transaction (KYT): Monitoring the Flow of Funds
Unlike KYC, which focuses on the person, KYT focuses intently on the digital assets themselves. KYT involves continuous, real-time analysis of blockchain activity to identify suspicious patterns, links to illicit wallets, or attempts to circumvent regulatory limits.
KYT utilizes sophisticated analytical tools to score transaction risk based on various factors:
- Source and destination of funds (Are they linked to darknet markets or sanctioned entities?)
- Transaction size and frequency compared to the user's profile
- Typology analysis (e.g., detecting chain hopping or mixing service usage)
- Tracing the transaction history through multiple hops on the blockchain
Core Differences: KYT vs KYC in Cryptocurrency
While both protocols are essential for AML compliance, their functions, timing, and primary focus are distinctly different:
Focus: KYC verifies the user’s identity (The Who). KYT monitors the flow and source of assets (The What).
Timing: KYC is generally performed during account onboarding. KYT is continuous and real-time throughout the entire account lifecycle.
Objective: KYC prevents illicit accounts from being created. KYT detects and flags illicit activity already in progress, often leading to fund freezing or reporting.
Data Used: KYC relies on personal documents and biographical data. KYT relies on blockchain addresses, hashes, cluster analysis, and network flow analysis.
Why VASPs Need Both Protocols for Robust Compliance
In modern regulatory environments, relying solely on identity verification is insufficient. KYC provides the necessary identity anchor, but without KYT, a legitimate, verified user could still unknowingly or knowingly transact with illicit sources without detection. The combination creates a robust compliance framework demanded by regulators like the Financial Action Task Force (FATF).
Holistic Risk Management: KYC establishes the baseline risk of the customer, while KYT dynamically adjusts that risk score based on real-time transactional behavior. If a low-risk customer suddenly engages in high-risk transaction patterns, KYT immediately flags the anomaly.
Mandatory Operational Requirement: Implementing effective, automated KYT solutions is now an essential operational requirement for any compliant cryptocurrency exchange, custodial wallet, or decentralized finance (DeFi) service acting as a VASP.
Conclusion
KYC and KYT are the twin pillars of regulatory adherence in the cryptocurrency world. KYC ensures accountability by tying real-world identities to digital wallets, while KYT ensures safety by continuously analyzing the transactional flow. Mastering both protocols is essential for VASPs aiming to maintain security, earn regulatory trust, and facilitate legitimate global financial market access.
