Nexus Mutual provides onchain insurance against smart contract bugs.

Being able to take out insurance helps to reduce the risk for 3rd parties to adopt new projects. For example:

Nexus token holders choose which projects they want to provide insurance for. In return they receive a share of the fees paid for the insurance cover. …
