# Risk Code Description

A single `risk_code` may represent: blacklist hit, indirect risk transaction, unknown, not found, etc.

Other composite `risk_code` values are constructed by concatenating the following elements in order:

> **Risk Type + Transaction Direction + Transaction Exposure Type + Risk Level**

These correspond to the configuration displayed on the KYT system rule engine page.
