# Wallet Overview

The Lacuna wallet is the heart of the protocol — everything else (swaps, bridging, agent payments) runs through it. It's a non-custodial mobile wallet: you hold the keys, the app holds nothing.

## What The Wallet Does

* Holds both **public** balances (normal on-chain) and **shielded** balances (private).
* Lets you **shield, unshield, and transfer** privately.
* Powers **private swaps, bridging, and x402 payments** from inside the shielded pool.
* Manages your **viewing keys** for optional, selective disclosure.

## Non-Custodial, Always

Your private keys and shielded note secrets are generated and stored only on your device. There is no Lacuna server that can access, freeze, or move your funds. If you lose your device, your [recovery phrase](/the-lacuna-wallet/backup-recovery.md) restores everything.

## The Privacy Model In One Picture

```
Public Address  --Shield-->    Shielded Pool   --Transfer / Swap / Pay-->   Private
Shielded Pool   --Unshield-->  Public Address
```
