OpenCover has launched Covered Vaults, a vault-native insurance layer designed to sit directly inside DeFi vault flows on Base. In a post on X, Base described the product as onchain vault insurance that can be toggled on or off by staking vault shares, with up to $50 million in coverage per vault.

According to OpenCover's launch statement, the system is now live in production and lets users activate protection without leaving the underlying protocol or buying a separate policy through a different interface. The company says the product was built to fit how vaults already work, using premium streaming and rolling renewals instead of forcing fixed-duration cover purchases.

That matters because DeFi users still carry residual smart contract, oracle, and governance risk even after audits and monitoring. Covered Vaults are meant to turn some of that uncertainty into a defined operating cost, which could make yield vaults easier for protocols, apps, and larger allocators to use.

Base's demo video shows the insurance layer embedded directly in the vault workflow, rather than added as an external step after deposit. OpenCover says coverage capacity is available immediately at up to $50 million per vault. The company has not yet published broader network-wide capacity figures, so the launch is best understood as new infrastructure for vault-level risk transfer rather than a blanket insurance backstop for DeFi as a whole.
