# Insurance Depositors can buy optional cover against smart-contract failure on Chamber vaults through [**OpenCover**](https://opencover.com/app/?invite=DH100K\&cover=126\&filter=Protocol+Cover\¤cy=USDC\&amount=50000\&duration=90). Cover is underwritten by **Nexus Mutual** and is purchased and paid for by the depositor — Chamber doesn't buy cover on your behalf. ## What's covered **Protocol cover** is the relevant product. It pays out if a smart-contract failure in the Chamber protocol causes loss of depositor funds. Depeg cover and Custody cover also exist on OpenCover but are not the primary cover for Chamber vault positions. Cover is priced in USDC, runs for up to 90 days at a time, and can be renewed. Cover is available across the same chains OpenCover currently supports for Chamber (Ethereum, Arbitrum, Base, Optimism, Polygon). Chamber chains outside that set are not covered today. ## What's *not* covered Insurance does not protect against: * **Market losses.** If the manager's trades go against you, that's market risk — not a contract failure. No cover pays for this. * **Strategy losses.** Leverage liquidations, LP impermanent loss, oracle drift, stablecoin depegs inside a vault's positions. These are disclosed on the vault page and in [Risks](/deposit/risks.md). * **Manager abandonment or inactivity.** The Guard System limits what a manager can do with funds, but it doesn't pay out if a manager stops managing. Cover exists specifically for the case where the Chamber contracts themselves fail — the same case that audits, the [Guard System](/security/guard-system.md), and the [bug bounty](/security/bug-bounty.md) are designed to prevent. ## How to buy cover 1. Go to [**OpenCover**](https://opencover.com/app/?invite=DH100K\&cover=126\&filter=Protocol+Cover\¤cy=USDC\&amount=50000\&duration=90). 2. Select **Protocol cover**, with Chamber as the covered protocol. If the OpenCover UI still lists the protocol as dHEDGE during the rebrand window, use that entry. 3. Enter the amount you want covered and the duration (up to 90 days). 4. Connect your wallet and pay the cover premium in USDC. Toros vaults sit inside the same protocol, so cover purchased via the same OpenCover listing applies — Toros product pages link to the same cover flow. ## Should you buy cover? That's a personal decision. A few pointers: * Cover makes more sense at larger deposit sizes where the premium is small relative to what's at risk. * It's an **add-on** to Chamber's built-in protections, not a substitute for checking the vault's risk profile before depositing. * If you're relying on cover, read the OpenCover policy terms so you understand what triggers a payout and what the claim process looks like — Chamber is not the underwriter. ## See also * [Risks](/deposit/risks.md) — the full list of what can go wrong, with or without cover. * [Security overview](/security/overview.md) — audits, Guard System, and incident history. * [Incident history](/security/incident-history.md) — actual loss events since launch. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
