What Makes C2C Compliance Uniquely Challenging
C2C (consumer-to-consumer) peer-to-peer crypto trading is the most fragmented and difficult-to-regulate segment of the OTC market. In this model, buyers and sellers transact directly, with the platform acting only as a facilitator — holding no funds and playing a limited role in the transaction itself. This creates inherent information asymmetry and makes regulatory oversight difficult to enforce.
Compared to traditional OTC desks, C2C participants are far more dispersed, with lower individual transaction amounts but extremely high transaction frequency. Criminal networks exploit these characteristics to layer illicit funds through large numbers of small C2C transactions, deliberately staying below the thresholds that would trigger automated risk controls. This "ant-moving" money laundering approach presents significant detection challenges for platforms and regulators alike.
Four Core Risk Categories in C2C Trading
Layering and structuring risk: Large sums of illicit funds are broken into dozens or hundreds of small C2C transactions, each of which appears individually unremarkable.
Fraudulent buyer risk: Scam operations use C2C channels to purchase crypto with funds that originated from fraud victims, making the platform an unwitting link in the laundering chain.
Address reuse risk: High-risk users frequently transact from the same addresses, creating identifiable behavioral patterns that go undetected without proper tooling.
Cross-platform fund movement risk: Users shift funds across multiple C2C platforms, exploiting the lack of information sharing between platforms to evade scrutiny.
How KYT Is Deployed in C2C Environments
The value of KYT in C2C contexts lies in its ability to combine on-chain behavior analysis with off-chain transaction records. Practical deployment occurs across three levels.
At the user level, KYT continuously profiles every wallet address participating in C2C transactions, assessing whether historical fund flows involve high-risk entities such as mixers, darknet markets, or known fraud addresses. At the transaction level, the system applies behavioral analysis to identify structuring patterns — flagging cases where transaction splitting behavior triggers manual review. At the platform level, KYT generates periodic user risk reports, helping compliance teams proactively identify high-risk user clusters before issues escalate.
C2C Platforms Cannot Escape AML Responsibility
Many C2C platforms assume that, as facilitators rather than direct participants, their compliance obligations are limited. However, regulators across multiple jurisdictions have made clear that any platform enabling conversion between fiat currency and crypto — regardless of the transaction model — is subject to AML requirements.
Deploying KYT is an effective way for C2C platforms to meet these obligations and reduce enforcement risk. More fundamentally, robust risk control capabilities build user trust and long-term platform credibility.
