# Open Cover

> Keeping you safe onchain

OpenCover is a DeFi cover platform that lets users purchase protection against smart contract hacks, stablecoin depegs, and other onchain risks.

OpenCover connects individuals and institutions protecting digital asset portfolios with vetted DeFi cover from established onchain underwriters. Users can purchase protocol cover, stablecoin depeg cover, yield token cover, and custody cover across multiple chains, with coverage represented by ERC-721 NFTs. The platform also operates an industry data dashboard tracking DeFi cover provider activity and offers Covered Vaults, a vault-native risk transfer primitive built on the ERC-7540 standard.

- [Covered Vaults](https://thegrid.id/profiles/Open_Cover): A vault-native risk transfer primitive enabling DeFi vault depositors to activate cover by depositing vault shares, with premiums streaming directly from yield and automatic renewals.
