Nexus Mutual

Nexus Mutual is a decentralized insurance protocol built on Ethereum that lets users purchase cover against financial losses caused by bugs or exploits in smart contract code. It targets participants in decentralized finance who want protection if a protocol they use is drained through an unintended use of its smart contracts. It also offers custody cover for centralized custodians and lenders, though losses from private key theft or centralized exchange hacks fall outside what the protocol covers.

Nexus Mutual operates on Ethereum and uses a mutual model in which NXM token holders collectively backstop claims rather than a traditional insurer doing so. Members stake NXM to assess risk on specific protocols, and claims are evaluated and voted on by other members who hold the token. There is no separate consensus algorithm — the protocol inherits Ethereum's underlying settlement layer and uses on-chain governance and staking mechanics to price, issue, and adjudicate cover.

Fees are generated by premiums that cover buyers pay to the protocol, with annualized fees of approximately 1,858,020 dollars projected from the trailing 30-day figure of 152,714 dollars. The protocol operates with a take rate of roughly 50 percent over the trailing 30 days, meaning it retains about half of gross premiums as protocol revenue, which annualizes to approximately 929,033 dollars from the same 30-day window. Over the trailing 12 months, total fees reached about 3,285,166 dollars and protocol revenue reached about 1,642,588 dollars. Holders and supply-side participants each received approximately 76,358 dollars in revenue over the trailing 30 days, reflecting how retained fees are distributed within the mutual.
