Interest Rate Module Audit for Morpho Blue

Fixed Rate Configuration Review of Morpho Blue

Morpho is a peer-to-peer lending optimizer that enhances capital efficiency by matching borrowers and suppliers directly within existing lending markets. The protocol recently introduced a fixed-rate Interest Rate Module (IRM) for its permissionless Morpho Blue system, enabling custom rate configuration per market.

To assess the security of this mechanism, Morpho engaged Cantina for a security audits review focused on the new fixed-rate IRM. The audit examined rate-setting controls, overflow protections, and edge cases where user funds could be locked due to invalid configurations.

In addition to formal reviews, Cantina supports safe protocol launches with offerings like bug bounty programs, crowdsourced security competitions, and multisig security, which help maintain reliability across permissionless infrastructure.
