# Contract addresses and deployments

*Open, verifiable, and live on testnet today.*

Lacuna's contracts are open and verifiable. The full protocol is deployed and running on Ethereum's Sepolia testnet today; mainnet addresses are published here at launch.

## Testnet Sepolia Deployment

The complete protocol pool, verifier, recovery, and governance has been live on the Sepolia testnet (chain ID `11155111`) since November 2025, where it has been audited and exercised. Every address below can be inspected on a block explorer and matched against the audited source.

| Contract          | Address (Sepolia)                            |
| ----------------- | -------------------------------------------- |
| Privacy Pool      | `0x33a5f045eECb8C17b0CBeaE29ed08e6D0E2ec5f5` |
| Verifier (router) | `0xbd66fF3f6a6a11429e9e2687B21e62a43685E3F1` |
| EmergencyExit     | `0xCAC45A7De1cb6bD98431fcF4d1406570B1ACE6Af` |
| Governance        | `0x7C0Ba50Cb24cE441e8679c2Cee31179353d06bb9` |

**Circuit verifiers** — Shield `0xDF41CaDa2eeadB79A48ddCD37EDe78A387544c0F` · Unshield `0x71475050bA47B37aa30cf5B3D4b8510eF3c9F386` · Transfer `0x50cD4EB467d15503bE7a3AAA32b068fF5C038c5F`.

**Test tokens** — USDC `0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238` · USDT `0xaA8E23Fb1079EA71e0a56F48a2aA51851D8433D0`.

## Mainnet deployment

Mainnet contracts will be deployed on Arbitrum and Ethereum at launch, with addresses published here and mirrored on the website. The decentralised relayer registry follows in a later phase.

| Contract         | Network  | Address               |
| ---------------- | -------- | --------------------- |
| Privacy Pool     | Arbitrum | *Published at launch* |
| Verifier         | Arbitrum | *Published at launch* |
| EmergencyExit    | Arbitrum | *Published at launch* |
| Relayer Registry | Phase 2  | *Published at launch* |
| Privacy Pool     | Ethereum | *Published at launch* |
| Verifier         | Ethereum | *Published at launch* |

## How to verify

Each address can be checked on the relevant block explorer and matched against the audited, published source. The contracts are immutable on their deployment chain and reject any operation that does not originate there.
