Onchain Reinsurance

Reinsurance contracts executed via blockchain smart contracts, with collateral held in stablecoin pools and payouts automated by oracle data.

Onchain reinsurance applies blockchain infrastructure to the mechanics of risk transfer. Smart contracts replace legal agreements and manual claims processes — collateral is held in tokenised stablecoin pools, triggers are fed by oracle data, and payouts execute automatically when trigger conditions are met.

The key advantage is automation and settlement speed. A parametric onchain cover triggered by earthquake magnitude data can settle in minutes, compared to months for traditional indemnity reinsurance. The key constraint is that most onchain structures are parametric, limiting their applicability to risks with clean, verifiable triggers.

Key onchain reinsurance protocols include re.xyz (fully collateralised institutional-grade contracts), Ensuro (parametric covers backed by USDC pools), onRe (onchain reinsurance marketplace connecting traditional risk to DeFi capital), Nexus Mutual (discretionary mutual for smart contract and DeFi risks), and Nayms (an onchain marketplace for ILS transactions).

Example usage

“Re.xyz completed its first fully onchain reinsurance contract for a Lloyd's syndicate, with USDC collateral held in a Ethereum smart contract.”
