List of Onchain Insurance companies in Web3 (2026)

OpenCover is an onchain insurance platform that lets users purchase and manage cover policies against DeFi risks such as smart contract exploits, oracle manipulation, governance attacks and stablecoin depegs. Policies are issued as ERC-721 NFTs to a user's wallet and are sourced from vetted third-party underwriters across multiple EVM-compatible chains. Individuals and institutions can compare cover options and buy protection for their portfolios without KYC.

Covered Vaults is a vault-native risk transfer product that lets DeFi vault depositors activate cover by staking their vault shares, with premiums streaming directly from yield and coverage renewing automatically. It extends the ERC-4626 tokenized vault standard through an extended ERC-7540 interface, allowing any compatible vault to become coverable without changing its deposit flow or underlying protocol. Underwriting is provided by a third-party mutual with onchain proof of solvency, and the product is accessible through its own reference interface across multiple chains and vault strategies.

Velocity Protocol is a decentralized perpetual futures exchange on Solana with an integrated money market. Each subaccount holds one pool of collateral that backs open perpetual positions while the same deposits are lent to borrowers, with fills priced through short market-maker auctions and an automated market maker. Depositors can lend idle collateral for yield or stake into insurance funds that cover liquidation shortfalls and earn a share of exchange fees. The exchange is in open beta following a rebuild after a security incident.

Lulo Protected is a decentralized stablecoin yield product that allocates deposits across leading lending and yield protocols using a systematic, TVL- and rate-weighted methodology rather than discretionary management. Deposits are non-custodial and routed directly into whitelisted integrated protocols, with a built-in coverage layer that automatically compensates depositors at the smart-contract level if an integrated protocol suffers a loss, with no manual claims process. A separate first-loss tier called Boost earns higher yield with a lockup period in exchange for underwriting that coverage, and the platform charges a performance fee on generated yield.

Nami Insurance is an onchain insurance contracts that allow users to hedge price fluctuations of supported assets.

Nexus Mutual is a decentralized discretionary mutual deployed on Ethereum where members pool capital to provide and share risk coverage. Members purchase cover against smart contract exploits, oracle failures, governance attacks, liquidation failures, custody failure, and validator slashing across EVM-compatible networks. Available cover types include Single Protocol Cover, Multi Protocol Cover, DeFi Pass Cover, Native Protocol Cover, Fund Portfolio Cover, ETH Slashing Cover, Quota Share Cover, and Crypto Kidnap & Ransom Cover for physical security risks. Members stake NXM to underwrite cover capacity, earn a share of premiums, and participate in decentralized claims assessment. Capital pool assets, claims history, and cover purchases are transparent onchain.

Lunos Coverage Platform implements on-chain insurance contracts through EigenLayer's AVS operator network, enabling automated claim verification for smart contract exploits, stablecoin depegs, validator slashing, and real-world asset risks. The system deploys AI agent pipelines to assess claims off-chain and records validated outcomes on-chain via cryptographic proof aggregation across independent operators.

Ensuro Protocol implements decentralized reinsurance through smart contracts and liquidity pools, enabling parametric insurance underwriting with automated claims settlement. The system manages eTokens for capital provision while maintaining regulatory compliance through licensed operations.

Alton Risk is a commercial insurance brokerage serving technology companies including AI, crypto, and venture-backed startups. It places specialty coverage across multiple lines, including D&O, cyber, tech E&O, AI liability, EPL, crime/fidelity, and property, through E&S, Lloyd's of London, and Bermuda markets. The firm also designs captive insurance programs and offers risk hedging through prediction markets for exposures not covered by traditional policies.

Sentora DeFi Cover provides integrated protection mechanisms for institutional DeFi capital, offering coverage solutions that defend against protocol exploits, smart contract failures, and other onchain risks within Sentora's yield strategies.
