Blockchain AML tools help assess risk information about address and transaction relationships. An on-chain observation and a real person's identity are not the same information.

## Data and labels

Labelling an address rests on a specific source or analysis. Do not draw definitive conclusions without knowing the label's meaning, freshness and confidence level.

## Direct and indirect relationships

A direct match differs from a relationship seen through other addresses. Analysis depth, transaction direction and time scope affect how a result is read.

## Decision context

Assess wallet risk together with customer and transaction information. A graph on its own does not establish source of funds or legal responsibility. Verify supported networks and analysis scope per product.
