## What changed

FinCEN issued an Iran-related whistleblower bulletin identifying digital-asset patterns that may indicate sanctions evasion or terrorist financing. Examples include payments involving Iranian exchanges or fronts, unusual corporate digital-asset payments, nested exchanges, and aggregation of small payments from many wallets. The bulletin solicits tips through the existing whistleblower program; it does not create a new sanctions designation or reporting obligation.

## Who it affects

- Digital-asset exchanges, custodians, and intermediaries reviewing Iran-related exposure
- Advisers reviewing client digital-asset transfers and service-provider controls
- Individuals with information about potential covered violations

## What is still open

- Whether a particular transaction pattern reflects prohibited activity rather than legitimate conduct
- Whether an individual tip satisfies statutory and regulatory award requirements

## What it means for an advisor

- Compare relevant exchange, counterparty, and wallet-monitoring controls with the bulletin's digital-asset examples.
- Escalate contextual indicators for review without treating an indicator alone as proof of a violation.
- Preserve transaction and counterparty records and distinguish whistleblower tips from separately applicable reporting duties.
