- Launch: V1 launched in September 2023; V2/MonoCooler is documented as launched in January 2025. Exact deployment timestamps: Not verifiable as of October 11, 2026.
- Chains: Ethereum mainnet only, according to Olympus documentation.
- Native token: No Cooler-specific native token identified. Core assets are OHM/gOHM collateral and USDS debt. Main contracts — Ethereum

A required second independent on-chain cross-check including Dune is unavailable in this run: Not verifiable as of October 11, 2026. Verification status for the other listed contracts: Not verifiable as of October 11, 2026. Fork lineage No evidence found that Cooler is a direct code fork of Ruler Loans or another deployed lending protocol; it is described as an Olympus-designed system inspired by fixed-term lending concepts. V2 is a material redesign of V1: per-user Cooler clones and lender-funded, fixed-term loans were replaced by one shared MonoCooler, Treasury-originated lending, perpetual debt, dynamic/governance-controlled LTV, delegation, composites, and a migration contract. V1 was audited by Sherlock; V2 received Electisec and Nethermind reviews. Similar-fork malicious-modification history: Not verifiable as of October 11, 2026. V1 audit materials did identify a malicious-callback denial-of-service risk in the generic design, illustrating fork/extension risk, not a confirmed exploit of deployed Cooler V2.
