# Welcome

Lacuna is a mobile-native, non-custodial privacy wallet. Shield your assets, then swap, bridge, transfer, and pay without exposing your activity on-chain. Your keys and your data stay on your device; nobody else can see or move your funds.

## Where To Start

* **New Here?** Read [What Is Lacuna?](/introduction/what-is-lacuna.md) for the big picture.
* **Want To Try It?** Jump to the [Quickstart](/getting-started/quickstart.md) and make your first private transfer.
* **Building On Lacuna?** Head to the [Wallet & Developer SDK](/for-developers/sdk.md).

## In Three Lines

1. **Shield** — move funds into a private shielded pool.
2. **Use** — transfer, swap, bridge, and pay privately from inside the pool.
3. **Unshield** — withdraw back to a public address whenever you want.
