# Viewing Keys & Selective Disclosure

Privacy by default doesn't mean you can never prove anything. Lacuna gives you **viewing keys** — read-only keys that reveal your activity to a chosen party, without giving them any ability to spend.

## What A Viewing Key Does

A viewing key lets someone *see* your shielded transactions — an auditor, an accountant, a regulator — while your spending keys stay private and on-device.

## You Stay In Control

* Sharing is **opt-in** — nothing is disclosed unless you choose to share it.
* It's **read-only** — a viewing key can never move your funds.
* It's **scoped** — you decide who gets it.

```ts
// Generate a read-only viewing key to share with an auditor
const viewingKey = await wallet.exportViewingKey();

// The holder can view — but never spend
const history = await LacunaViewer.getHistory({ viewingKey });
```

This is the foundation for [Compliance Integrations](/security-and-compliance/compliance-integrations.md) and the planned [Proof Of Innocence](/security-and-compliance/proof-of-innocence.md).
