Security

Nexus Mutual works to ensure our smart contract system is safe and secure. Regular audits are an important part of maintaining the security of our smart contract system, but there are several other approaches the mutual takes to keep the protocol secure.

Immunefi Bug Bounty

On Immunefi, hackers secure DeFi contracts, save funds from theft, and get paid doing it. Nexus is able to secure our protocol through this partnership with Immunefi.
Immunefi runs a bug bounty programme for Nexus Mutual to incentivise hackers to disclose vulnerabilities in the mutual's smart contract system in exchange for payouts equal to the level of severity.
