A crypto risk score is a 0–100 number summarizing a wallet's exposure to sanctions, mixers, scams and stolen funds, mapped to a Low-to-Critical verdict; Plastron computes this score free across seven EVM chains.

Blockchain analytics firms developed wallet risk scoring as a practical solution to a specific problem: how do you quickly convey to a compliance officer or exchange system whether a particular wallet address presents a meaningful AML concern? A raw transaction graph is too complex to review manually at scale — exchanges process hundreds of thousands of deposits per day, and no human team can examine each one in depth. The risk score compresses that analysis into a number from 0 to 100 that a system can act on automatically. At Plastron, the risk score is calculated across six weighted categories. Sanctions exposure carries the most weight at 30%, reflecting that OFAC violations carry the most severe regulatory consequences. Mixer exposure follows at 25%, as mixer use is the clearest behavioural signal of intent to obscure fund flows. Stolen fund exposure contributes 20%, reflecting the direct link to criminal activity. Darknet market exposure carries 10%, fraud exposure 10%, and phishing-related exposure 5%. These weights reflect how compliance teams prioritize risk signals in practice. The composite score also applies override rules: a direct OFAC designation match forces the score to 100 regardless of other factors; any critical-severity flag pushes the score to at least 70; two or more high-severity flags push it to at least 50. Understanding your score means understanding which categories are driving it — because that determines what an exchange will flag and what documentation you will need to explain.
