**Private money for public chains** — self-custodial, zero-knowledge, from your phone. Send, swap, and bridge without putting your finances on display.

***

Public blockchains made money programmable and verifiable  and, in the same stroke, made every balance, payment, and counterparty permanently visible to anyone. Traditional finance keeps individual activity private; on-chain, nothing is. As stablecoin payments scale into a mainstream rail and autonomous agents begin to transact on their own behalf, that exposure turns from an inconvenience into a liability.

**Lacuna** is a mobile-native, non-custodial privacy protocol. Users shield assets into a zero-knowledge pool, then transfer, swap, and bridge privately before withdrawing to any address, with proofs generated on the device and keys that never leave it. Around this core, Lacuna adds **EmergencyExit** for coercion- and compromise-resistant recovery, gasless withdrawals, and an open developer surface so others can build on the same privacy layer.

The protocol and mobile app run on a public testnet and are audited by SolidProof. Mainnet is the immediate next milestone.

| **Built for what's next** | A confidential settlement layer for people and the agent economy.            |
