What is Model Drift in Crypto Onramps and Exchanges?
Model drift occurs when fraud or risk models lose accuracy over time because transaction behavior evolves faster than the model adapts.
In crypto onramps, this happens as fraud tactics mutate rapidly.
How Drift Forms
Drift forms when:
- New wallet behaviors emerge
- Attackers adapt to detection rules
- Legitimate user behavior changes
- Training data becomes stale
Why Crypto Amplifies Drift
Crypto systems drift faster because:
- Transactions are irreversible
- Identity signals are weak
- Cross-border volume is high
- Fraud patterns mutate quickly
System Consequences
Drift causes:
- Rising false positives
- Missed fraud detection
- Regulatory exposure
- Liquidity instability
