On‑chain vault insurance on Base
OpenCover launched an on‑chain vault insurance product on Base that can insure any DeFi vault and offers up to $50 million of coverage via staking vault shares. That design creates a protocol-native safety net for vault strategies while shifting underwriting and capital dynamics on Base. (x.com)
OpenCover launched a vault-native insurance product called Covered Vaults on Base. (opencover.com) The product attaches insurance directly to yield-bearing vault shares. (opencover.com) OpenCover says coverage capacity starts at up to $50 million per vault. (opencover.com) You deposit into the original vault exactly as before. (opencover.com) Then you stake the vault shares into an OpenCover Covered Vault to enable protection. (opencover.com) Staking those shares activates cover without changing the vault’s deposit flow. (github.com) Premiums are charged as a fixed yearly rate. (opencover.com) Those premiums are streamed from the vault’s yield while protection is active. (opencover.com) That removes the need for upfront payments or manual renewals. (opencover.com) Underwriting and capital live onchain. (opencover.com) Nexus Mutual supplies the underwriting framework and capital support. (opencover.com) Underwriting capital is locked onchain to back the staked vault value. (opencover.com) OpenCover built the primitive around an extended ERC-7540 vault standard. (opencover.com) That design keeps composability with ERC-4626-style vaults. (opencover.com) It aims to support many vaults without protocol-level changes. (github.com) OpenCover launched the product with design partners such as Morpho and Kiln. (opencover.com) Base is listed among the launch partners and supported chains. (einnews.com) OpenCover says covered vaults are live protecting eight-figure TVL in initial deployments. (opencover.com) OpenCover ran a Sherlock audit contest for the Insured Vault code. (audits.sherlock.xyz) The contest posted roughly $18,500 in rewards for auditors. (opencover.substack.com) OpenCover later reported zero valid findings from the audit process. (outposts.io) Covered Vaults can scale capacity by restaking underwriting capital. (opencover.com) OpenCover says restaking will push capacity beyond the initial $50 million. (opencover.com) That mechanism changes how underwriting capital is allocated on Base. (opencover.com) A few live offerings are already listed, including an stETH ARM covered vault. (outposts.io) The product’s UI and integration guide live at OpenCover’s vaults page. (opencover.com) Developers can inspect the audited code and contest repo on OpenCover’s GitHub. (github.com)
