Nexus Mutual vs InsurAce: DeFi Insurance Comparison 2026
DeFi insurance has become essential for protecting against smart contract failures, hacks, and protocol exploits. Nexus Mutual and InsurAce are the two leading decentralized insurance protocols, each offering different approaches to coverage. This comparison helps you understand which platform better protects your DeFi investments.
Protocol Overview
Nexus Mutual launched in 2019 as the first decentralized insurance alternative. Operating as a discretionary mutual, it pioneered DeFi coverage with a member-owned structure. NXM token holders govern the protocol and stake to underwrite coverage, sharing in premiums and bearing claim risk. InsurAce launched in 2021 with a multi-chain approach and broader coverage options. The protocol aims to offer lower premiums through portfolio diversification and efficient capital utilization. INSUR token governance and staking drive the system.Coverage Types
