# LabelsForEvent

> Container for sandwich and washtrade detection labels attributed to a single Event.

### TypeScript shape

```ts theme={null}
interface LabelsForEvent {
  sandwich: SandwichLabelForEvent | null;
  washtrade: WashtradeLabelForEvent | null;
}

Currently emitted as `null` on every event. Use the dedicated [`onEventLabelCreated`](/api-reference/graphql/subscriptions/onEventLabelCreated) subscription for live MEV labels.
