# FAQ

**Is Lacuna Custodial?** No. Your keys and funds stay on your device. Lacuna cannot access, freeze, or move them.

**Is It Live On Mainnet?** Not yet — the protocol is currently on the Ethereum Sepolia testnet. Mainnet follows the on-device-proving re-audit. See the [Roadmap](/resources/roadmap.md).

**Do I Need Gas Tokens To Use It?** No — [relayers](/how-lacuna-works/relayer-network.md) can broadcast transactions and take the fee from your shielded balance.

**Can I Prove My Activity If I Need To?** Yes — [viewing keys](/the-lacuna-wallet/viewing-keys.md) let you share read-only visibility on your own terms. [Proof Of Innocence](/security-and-compliance/proof-of-innocence.md) (Phase 2) will extend this.

**What Happens If I Lose My Phone?** Restore your wallet on a new device with your recovery phrase. Without it, funds can't be recovered — that's the nature of self-custody.

**Is Proof Of Innocence Available Now?** No — it's planned for Phase 2. The design is documented; the on-chain components are not yet live.
