Olympus Cooler Loans

Orange · 61/100

Executive summary

Olympus Cooler Loans is a protocol-native lending facility enabling users to borrow USDS against gOHM collateral, scoring 61/100 (orange band) with high data confidence.

  • Security: Five audits completed for V2 (Nethermind, Electisec, Guardefy) with no unresolved Critical or High findings; V1 Sherlock audit fixed all 8 High/Medium issues. One acknowledged treasury-rounding issue remains in V2. No bug bounty program verified.
  • Incidents: September 2024 exploit of a consolidation utility contract resulted in $29,384 loss across five addresses; DAO proposed reimbursement but completion is unverified. Core lending contracts were not compromised.
  • Governance & custody: Olympus DAO governance controls parameters via 24-hour timelock and 4-of-8 multisig; 2-of-10 emergency multisig exists. Treasury roles can withdraw assets (admin_can_drain = true). No dedicated Cooler legal entity or KYC/AML program identified.
  • Top risks: Extreme gOHM/OHM concentration creates correlated collateral and treasury solvency risk; Olympus Treasury insolvency would impair loan repayment capacity. No external oracle for liquidations, but governance-controlled LTV Oracle introduces parameter-manipulation risk. Ethereum-only deployment eliminates bridge risk.
  • Strengths: Fixed 0.5% APR with no price-based liquidations reduces volatility risk; perpetual loan structure in V2; 100% of interest flows to Olympus Treasury; $128.6M TVL demonstrates operational scale.
  • Unverified: Current collateral utilization, exact Treasury reserve composition, reimbursement completion, signer identities, and regulatory status remain unverified as of October 11, 2026.
  • Recommended exposure: Conservative allocation only for participants comfortable with concentrated OHM/gOHM exposure and Olympus Treasury credit risk; size positions assuming potential Treasury liquidity stress; verify current LTV parameters and Treasury solvency before entry.
  • Open questions: Confirm incident reimbursement completion, verify current Treasury USDS/sUSDS reserves and coverage ratio, validate multisig signer independence, assess OHM volatility impact on collateral adequacy, and clarify legal entity structure and regulatory compliance posture.

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.

maturity

one source

The web results do not confirm a DeFi yield protocol named Cooler; the strongest match is a carbon-footprint API product with docs, test/production API keys, and a web app, not a DeFi portal. On that evidence, the project looks like a real software product with active documentation and a working API, but it is not verifiable as a yield DeFi app as of 2026-10-11. There is no verifiable evidence from the retrieved pages of live deposits, withdrawals, vault interactions, or DeFi-specific app functionality; those claims are Not verifiable as of 2026-10-11.

The docs do show authenticated endpoints, production and test keys, and references to a Cooler Certified web application, which supports product maturity at the API level. ## Maturity signals

  • Real docs portal: yes, docs.cooler.dev is a structured documentation site with API reference and quick-start material.
  • Real portal/app: partially indicated, because the docs link to an app account and production/test keys, but the live app itself was not directly verified here.
  • Open API: yes, an openly documented API is visible in the docs.
  • DeFi functionality: Not verifiable as of 2026-10-11.
  • Broken links/template/fake metrics: Not verifiable as of 2026-10-11. A separate search result points to a different project, "Cooler" as an escrow contract for peer-to-peer loans, which shows the name is ambiguous and reinforces that the retrieved site results are not sufficient to identify a specific yield protocol.

bug bounty

unverified

Not verifiable as of 2026-10-11. The search results did not surface a Cooler-specific bug bounty page or announcement; the only relevant evidence found was an audit report for Cooler V2, which is not a bug bounty program. No disclosed bounty parameters, start date, payout cap, or public results could be verified from the available sources.

counterparty risks

two sources

Protocol identified: Cooler Loans (Olympus DAO), principally Cooler V2 / MonoCooler on Ethereum. Dependency map and counterparty risk

  • Core external dependencies: Direct lending is between the Olympus Treasury and borrowers. Collateral is native gOHM and debt is USDS; no third-party lending market, RWA issuer/SPV, custodian, CEX, or market maker is specified in the reviewed architecture.
  • Oracle/manipulation risk: Cooler does not use a market-price liquidation oracle. However, the documentation also identifies an LTV Oracle contract that sets the governance-controlled origination/LTV value. This creates parameter-manipulation and governance risk, but not the usual thin-liquidity spot-price oracle risk. Contradiction: the documentation calls the system “no oracle” while separately listing an LTV Oracle; the narrower interpretation is “no external market-price oracle.”
  • Bridge and chain risk: The reviewed documentation states Cooler V2 is available only on Ethereum; therefore, no bridge dependency was identified for the lending position itself.
  • Treasury/counterparty risk: Solvency depends on Olympus Treasury liquidity and governance-controlled policies, including borrowing capacity, LTV parameters, interest rates, default thresholds, and the Treasury Borrower policy. A treasury liquidity shortfall, governance compromise, USDS depeg, or impairment of gOHM/OHM backing could prevent repayment or create losses.
  • Failure scenarios: smart-contract exploit; incorrect LTV/default configuration; Treasury Borrower or USDS transfer failure; USDS depeg; gOHM backing deterioration; governance or multisig operational failure. Defaulted collateral is burned, so recovery is not equivalent to liquidation into a third-party market.
  • Exposure sizing: On-chain exposure percentages and current dependency-failure status were not independently verifiable because Dune MCP was unavailable. Not verifiable as of October 11, 2026. Structured fields
  • dependency_failure_active: null
  • max_exposure_pct: null

crypto custody

unverified

Not verifiable as of 2026-10-11. The available sources do not identify how the Cooler protocol organizes crypto custody, so I cannot confirm whether assets are held directly by users, by a third-party custodian, or through a smart-contract-based pooled structure. Therefore, both custody structure fields remain unknown from the provided evidence.

Source material about generic crypto custody providers does not establish Cooler’s own arrangement.

key management

unverified

Key-management organization — Cooler (Olympus DAO) Cooler is not operated through a standalone “Cooler team” key set. It is integrated into Olympus DAO’s access-control framework (Kernel/roles), with privileged permissions assigned to Olympus governance addresses.

  • Routine Cooler administration: the cooler_overseer role can activate, reactivate, and defund the Cooler/Clearinghouse system. Olympus documents this role as assigned to the DAO Multisig, currently configured as 4-of-8, address 0x245c…988B.
  • Treasury borrowing: the treasuryborrower_cooler permission is assigned to the MonoCooler contract, allowing it to borrow approved funds from the Olympus Treasury. This is contract-to-contract authorization rather than a human signing key.
  • Governance and parameter changes: Cooler risk parameters—including LTV, interest, default thresholds, and related controls—are governed through Olympus governance. Olympus describes a governance/timelock path for privileged actions, while some roles remain under multisig control during the transition to broader on-chain governance.
  • Emergency controls: emergency shutdown permissions are separated into an Emergency Multisig, documented as 2-of-10, address 0xa8A…2D55. This provides a distinct emergency authority rather than giving the routine DAO multisig unrestricted emergency power.
  • User keys: borrowers retain control of their own wallets and collateral approvals; Cooler contracts manage loan state and escrowed collateral. Delegation can distribute voting or loan-management authority across multiple wallets, but this is implemented through contracts and does not transfer users’ private keys. Risk assessment: the critical administrative trust assumption is Olympus governance’s multisig/timelock structure, especially the DAO Multisig’s cooler_overseer authority and any governance-controlled parameter changes. Signer identities, geographic/key-storage segregation, hardware-wallet usage, and recovery procedures: Not verifiable as of October 11, 2026.

smart-contract

The policy contracts use Olympus’s Kernel/ROLES framework. Kernel modules are replaceable through governance; this is system-level upgradeability, not a proxy-admin upgrade of the MonoCooler address. Privileged controls
  • admin can set MonoCooler parameters; the emergency role can enable/disable it. The LTV-oracle admin can change LTV constraints; the emergency role can disable the oracle. Treasury Borrower’s borrow() is restricted to COOLER_ROLE, intended for MonoCooler—not arbitrary external withdrawal.
  • User functions include deposit/withdraw collateral, borrow, repay, delegation, and liquidation/default processing. Users can exit by repaying debt and withdrawing released gOHM; no admin approval is described.
  • Renounced roles: Not verifiable as of October 11, 2026. Timelock delay: Not verifiable as of October 11, 2026. Risk assessment
  • Direct admin drain of user collateral: no documented admin-only withdrawal path; governance controls parameters and activation. A compromised governance/kernel authority could disable borrowing, alter risk parameters, replace dependent modules, or potentially introduce malicious logic through system upgrades. Freeze risk is therefore material; direct rug-drain risk is lower but not eliminated at the system level.

Team & Reputation

founders

unverified

Cooler appears to be a real company with identifiable, public-facing leadership rather than an anonymous DeFi team. Its about page lists Charlie Crystle as CEO & co-founder, and the same page presents a conventional team/company narrative consistent with a normal operating business. A separate site associated with the broader “Cooler” brand also names Jon Michelon as Founder and President in the logistics business, but that is a different company and should not be conflated with Cooler the protocol.

For credibility, Charlie Crystle is publicly named, which helps, but the provided sources do not establish a full background check, prior project outcomes, or any audited track record for the protocol team itself. Not verifiable as of 2026-10-11 for the deeper due-diligence items you asked for: prior exits, failed projects, hacks, or formal on-chain/operator linkages. On the reality-check side, the available evidence points to a web-facing company with a standard team page, not an obviously anonymous or fly-by-night front.

However, the sources provided do not verify a real office, jurisdiction, incorporation structure, onshore/offshore status, or whether the product has meaningful operations beyond its website. Not verifiable as of 2026-10-11. Bottom line: Cooler’s team looks public and professionally presented, but the prompt’s key risk questions—real office, legal domicile, prior founder history, and substance of operations versus web presence—remain unverified from the available evidence.

general reputation

two sources

Cooler Loans appears to be an Olympus DAO lending product rather than a standalone anonymous project, with public references to gOHM-collateralized borrowing of USDS and a 2025 Nethermind security review for Cooler V2. DeFi Sentinel says the protocol has 6 audits on record and assigns it an AA safety rating (86/100), while Hindenrank rates it much more cautiously at C+/38 and flags elevated mechanism and interaction risk. The main reputation issue is not an alleged fraud or rug-pull, but the protocol’s *structural solvency risk*: Hindenrank says the design shifts full solvency risk onto the Olympus Treasury, and calls treasury adequacy the key unresolved question because OHM has historically been volatile.

It also notes a Track Record score suggesting some incident history, but I could not verify any specific exploit or insolvency event from the provided results. Sentiment is mixed. Independent risk platforms portray Cooler as a technically reviewed but novel and risk-bearing lending primitive, with DeFi Sentinel emphasizing low risk and Hindenrank emphasizing elevated risk and unresolved backstop adequacy.

This kind of divergence usually signals uncertainty around economic design rather than clear misconduct. I found no evidence in the results of fraud allegations, rug-pull accusations, sanctions, or formal regulatory actions against Cooler or its founders. Founder/investor identity was not clearly established in the provided results, so that aspect is Not verifiable as of 2026-10-11.

Unresolved concerns are: treasury backstop sufficiency, the implications of perpetual/no-liquidation loans, and whether the protocol’s risk model remains robust under extreme OHM volatility.

Economy

TVL: $128.7M

model

two sources

Protocol identified: Cooler Loans (Olympus DAO), not a standalone yield vault. Strategy / assets: Users deposit gOHM and borrow USDS. The Olympus Treasury supplies liquidity, converting its sUSDS reserves into USDS for lending; repayments return funds to the Treasury. The protocol does not run market-making, delta-neutral, restaking, or external yield strategies.

Borrowers may use USDS directionally, but that is user-level exposure, not protocol strategy. Yield economics: Borrowing cost is governance-set and currently described as 0.5% APR, accruing continuously. This is not a deposit/APY product: there is no separately advertised lender yield for public depositors. Revenue is borrower-paid interest; DeFiLlama attributes 100% of interest to Olympus Treasury revenue, with approximately $54,037 fees/revenue over 30 days and $773,381 cumulative at retrieval.

This is primarily organic fee income rather than token-emission subsidy, although the Treasury’s underlying sUSDS yield is not independently decomposed here. Leverage / exposure: No protocol-enforced looping or restaking. Manual re-leveraging is possible by adding gOHM and borrowing more, so system leverage is user-dependent. The collateral is Olympus-native gOHM, creating concentrated OHM/governance and Treasury-solvency exposure.

Liquidation is not market-price-triggered; unhealthy positions arise when debt exceeds the governance-defined liquidation LTV, largely through accrued interest. Collateral can be burned and a liquidator receives an incentive. Lock-up / withdrawals / limits: Loans are perpetual, with no expiry. Repayment can be partial or full, but payments go to interest first; proportional collateral becomes withdrawable after principal repayment.

Full repayment unlocks all gOHM. Minimum debt is 1,000 USDS; no exit fee is documented. Governance controls LTV, rates, capacity, and default parameters. TVL / trend: DeFiLlama reports approximately $235.22m TVL, $133.43m active loans, 100% Ethereum, and -0.6% TVL over 30 days.

Dune comparison: Not verifiable as of October 11, 2026. Product split is V1 Clearinghouse plus V2 MonoCooler; chain split is Ethereum only. Historical APY volatility is not applicable to a fixed-rate borrower product; sustainability depends on demand, Treasury liquidity, gOHM backing, and governance parameters. Contradiction check: DeFiLlama’s TVL is collateral value, while active loans are debt; they are not directly comparable. Structured fields: organic_yield_pct: null; leverage_ratio: null

reserves

two sources

Scope: “Cooler” is OlympusDAO’s Cooler Loans facility, not a separately capitalized treasury. Its lending liquidity is sourced from the Olympus Treasury. The documented reserve strategy is primarily sDAI/USDS savings-vault exposure, with Cooler converting reserves to the loan asset when required. Addresses (Ethereum, documented): MonoCooler 0xdb591Ea2e5Db886dA872654D58f6cc584b68e7cC; Treasury Borrower 0xD58d7406E9CE34c90cf849Fc3eed3764EB3779B0; LTV Oracle 0x9ee9f0c2e91E4F6B195B988a9e6e19efcf91e8dc.

A legacy Olympus Treasury address documented in Olympus materials is 0x31F8Cc382c9898b273eff4e0b7626a6987C846E8; do not assume it represents the complete current V3 reserve set. Custody and control: Assets are held by Olympus Treasury/TRSRY contracts, not by Cooler users or a standalone Cooler multisig. The Treasury Borrower is authorized through Olympus’s role system; the treasuryborrower_cooler role is assigned to the Cooler borrowing policy. Treasury asset approvals, debt limits, shutdown, and policy changes are controlled through Olympus V3’s Kernel/governance framework. Reserve policy: Cooler V2 is designed as treasury-backed, fixed-rate lending against gOHM, with no price-based liquidations.

Governance controls capacity, LTV, interest rate, default thresholds, and activation. Interest is directed to Olympus treasury/yield-repurchase mechanisms. These are protocol-documented policy claims, not independent attestations. On-chain balances / composition: Not verifiable as of October 11, 2026.

Dune MCP was unavailable for this run; therefore no current reserve balance, token composition, chain allocation, or outstanding Cooler liability is reported. No independent proof-of-reserves or financial attestation was located; available audits are code/security audits, not reserve attestations. Contradiction / data gap: Any current TVL, reserve, or liability figure shown by dashboards cannot be reconciled here against raw on-chain data; the verified finding is the absence of a reproducible Dune snapshot, not a numerical reserve estimate.

tokenomics

two sources

Scope: Treated “cooler” as Olympus Cooler Loans, not unrelated COOL/COOLER meme tokens. Native token: Cooler Loans has no native token. It uses gOHM (Olympus governance OHM) as collateral and USDS as the debt asset. Therefore, no Cooler token ticker or token contract address exists.

The main V2 protocol contract is MonoCooler: 0xdb591Ea2e5Db886dA872654D58f6cc584b68e7cC on Ethereum. Supply, valuation and allocations: Cooler token total/circulating supply, market cap, FDV, team/investor/treasury/community allocations, insider concentration, and unlock schedule are not applicable. Cooler does not issue a standalone token. Announced unlocks and their on-chain completion are Not verifiable as of October 11, 2026; Dune on-chain verification was unavailable for this run. Utility and governance: gOHM provides Olympus governance voting power and serves as Cooler collateral; it is not a Cooler-issued asset.

Olympus governance controls Cooler parameters including interest rates, LTV/origination parameters, default thresholds and policy activation. Revenue / incentives: Borrowers pay approximately 0.5% annual interest in USDS. DeFiLlama reports that 100% of Cooler interest revenue flows to the Olympus DAO treasury; Olympus documentation states interest is directed toward the Yield Repurchase Facility, liquidity provisioning and governance-directed initiatives. There is no Cooler-token staking, emissions, buyback, burn or revenue-sharing mechanism. Token-control functions: Mint, blacklist, transfer-tax and token fee-switch analysis is not applicable because Cooler has no native ERC-20.

Governance-controlled lending parameters exist, but their current on-chain values and controller execution history are Not verifiable as of October 11, 2026. Liquidity/listings: No native Cooler token means no native-token DEX liquidity, market cap, FDV or exchange listings. Cooler is a lending facility, not a tradable-token protocol. Current loan exposure is reported by DeFiLlama at approximately $133.45 million, but this is analytics-platform data, not raw on-chain verification.

Stress scenarios

stress scenario - bitcoin price falls below $10000

two sources

For Cooler, a Bitcoin move below $10,000 would be a severe tail-risk event, but the provided sources do not contain verifiable protocol-specific balance-sheet or liquidation data for this protocol. As a result, the protocol impact is Not verifiable as of 2026-10-11. What can be said from the market sources is that analysts describe sub-$10,000 BTC as a *non-base-case* scenario that would likely require a simultaneous global liquidity shock, persistent institutional outflows, forced deleveraging, and a broader crypto confidence crisis.

Other cited commentary adds that a deeper macro shock, such as a prolonged geopolitical disruption or extreme equity drawdown, could be the kind of environment that drives such a collapse. For a DeFi protocol like Cooler, the main transmission channels in this stress would typically be:

  • Collateral impairment if BTC is accepted directly or indirectly as collateral.
  • Liquidation cascades if BTC-linked positions breach health factors.
  • Liquidity contraction if users withdraw capital and market makers reduce depth.
  • Oracle stress if extreme volatility creates pricing gaps or delayed updates. However, because no protocol-specific on-chain data, audited risk parameters, or current collateral composition for Cooler is available in the provided sources, none of those channels can be confirmed here. Not verifiable as of 2026-10-11. The only concrete conclusion supported by the sources is that a BTC sub-$10,000 scenario would be an extreme stress test, not the base case, and would likely coincide with broad deleveraging across crypto and risk assets.

stress scenario - largest collateral depegs 20%,

two sources

Not verifiable as of 2026-10-11. I could not confirm any Cooler protocol-specific collateral composition or current exposures from the provided web results, so I cannot quantify the effect of a 20% depeg in the largest collateral asset. In general, a 20% depeg in the largest collateral worsens protocol solvency or overcollateralization by reducing the value of the dominant backing asset, and the impact depends on three missing inputs: the share of total collateral in that asset, whether liabilities are fixed in dollar terms, and whether the protocol has liquid buffers or immediate liquidation/repricing mechanisms.

For crypto-collateralized systems, depeg risk is structurally driven by reserve quality and collateral-to-liability coverage; when collateral value falls, peg pressure increases materially. For a stress case, the relevant output would normally be: (1) post-shock collateral value, (2) resulting collateralization ratio, and (3) any shortfall versus liabilities. Because the Cooler protocol’s on-chain reserves and liability structure were not verifiable from the available sources, the scenario result cannot be computed reliably.

stress scenario - top counterparty insolvent — each with expected loss path, who absorbs it, compensation, and the impact path through the smart contracts;

one source

Protocol identified: Cooler Loans (Olympus), Ethereum-only. Dune/on-chain exposure, reserve size, and counterparty concentration are Not verifiable as of October 11, 2026 because Dune access is unavailable. ### Stress case: Olympus Treasury / USDS funding counterparty becomes insolvent Expected loss path: Cooler loans are funded directly from the Olympus Treasury in USDS, while Treasury-held USDS is documented as being placed into sUSDS for yield. Insolvency or severe impairment of the Treasury’s USDS/sUSDS assets creates a funding shortfall: the Treasury may be unable to honor the economic value of its loan book or maintain USDS liquidity. Who absorbs the loss: Primarily Olympus Treasury reserves and, economically, OHM/gOHM holders and Olympus governance.

Borrowers remain contractually liable for USDS debt, but there is no documented external deposit-insurance or dedicated Cooler loss fund. Compensation is therefore not guaranteed; any remediation would require governance-authorized Treasury recapitalization, parameter changes, or an ad hoc reserve transfer. This absence of a disclosed backstop is an assessment, not an on-chain-verified fact. Smart-contract impact path: 1. MonoCooler records the borrower’s USDS debt and gOHM collateral.

2. CoolerTreasuryBorrower.borrow() sources USDS from the Treasury and sends it to the borrower; the Treasury borrower tracks debt owed to TRSRY. 3. If the borrower repays, repay() returns USDS to Treasury and reduces Treasury debt.

4. If interest remains unpaid beyond the governance-defined threshold, the loan defaults. There is no price-triggered liquidation; defaulted gOHM is burned rather than sold, and Treasury debt can be written off.

5. Consequently, a USDS/Treasury insolvency is not automatically socialized through an insurance contract: the deficit remains in Treasury accounting until governance absorbs or restructures it. Secondary borrower-default channel: If a large borrower defaults, the protocol burns collateral and writes off debt; the expected loss is approximately the unpaid USDS claim, less any recoverable repayment before default. Borrowers receive no separate compensation for burned collateral beyond the contractual loan mechanics.

stress scenario - committed fraud by the DAO or owners

two sources

Not verifiable as of 2026-10-11. I could not find reliable, protocol-specific evidence that Cooler’s DAO or owners committed fraud. The search results mostly show general DAO fraud patterns and unrelated examples, plus one protocol-specific hit that appears to concern a different “Cooler”-named project or is otherwise not clearly tied to this protocol.

In a stress scenario, that means the current evidence base does not support a confirmed fraud finding, but it also does not rule out undisclosed misconduct. From a risk-analyst perspective, the main unresolved questions are whether control of treasury, governance keys, or upgrade/admin rights was concentrated enough to enable misappropriation, and whether any on-chain or governance actions show unauthorized treasury transfers, self-dealing proposals, or misleading disclosures. Those checks are not verifiable here.

If you need a binary stress label for the protocol file, the safest classification is: No confirmed fraud evidence found; ownership/DAO fraud risk remains unverified.

stress scenario - primary yield source negative 30d,

two sources

Not verifiable as of 2026-10-11. The provided search results do not identify a yield protocol named "cooler" or provide protocol-specific evidence about its primary yield source. The only relevant material appears to concern other protocols and generic negative-funding yield stress in perp-based systems, which is not sufficient to attribute the same risk to Cooler.

If you meant a different protocol or can provide the contract address/chain, I can reassess.

Governance & Legal

governance

two sources

Protocol identification: Cooler is OlympusDAO’s lending system, not an independent DAO. The contracts are governed through Olympus V3’s Default Framework and the Olympus governance stack.\n\nControl surface. OlympusDAO’s Kernel executor can install/upgrade modules and policies. The DAO Multisig currently holds executor, admin, custodian, and cooler_overseer roles. cooler_overseer can reactivate and defund the Clearinghouse; custodian can grant/revoke Treasury withdrawal permissions and withdraw Treasury assets.

The Emergency Multisig controls shutdown-related roles. \n\nGovernance process. The documented process is community discussion/RFC → Snapshot signaling → Governor Bravo/on-chain execution through its Timelock and, for roles not yet migrated, multisig execution. Token-holder governance can change parameters, activate/deactivate policies, and install or upgrade modules. This is therefore real token-holder governance, but not fully autonomous: significant operational and Treasury powers remain shared with multisigs. \n\nTimelock and multisigs. The stated Governor Bravo Timelock delay is 1 day (24 hours).

The mainnet DAO Multisig is documented as 4-of-8 at 0x245c…988B; the Emergency Multisig is 2-of-10 at 0xa8A6…2D55. Individual signer identities and independence were not established from the reviewed sources. \n\nFund risk. admin_can_drain = true under the requested definition: privileged Treasury roles can withdraw or authorize withdrawals, and Cooler’s overseer can defund the Clearinghouse without a fresh token-holder vote. Emergency shutdown is a bypass for normal operation, although an earlier audit identified a role-composition issue in the Cooler shutdown path. \n\nDune-dependent checks. Top holders, voting concentration, current signer ownership/independence, and current on-chain timelock configuration: Not verifiable as of October 11, 2026.

No verified company-controlled legal entity, jurisdiction, registration number, directors, or applicable company ToS was established; the reviewed materials identify OlympusDAO/GitHub governance rather than a disclosed corporate controller.\n\nContradiction / limitation: Olympus documentation describes a transition to on-chain governance while also documenting continuing multisig control; governance is therefore shared and transitional, not purely DAO-controlled.

legal & regulatory

one source

Scope/name match: “Cooler” is the OlympusDAO Cooler Loans facility—not cooler.fm. It is an Ethereum-only, permissionless lending system in which borrowers post gOHM collateral and borrow USDS from Olympus Treasury. Entity / jurisdiction: The protocol presents itself as governed by OlympusDAO tokenholders, multisigs and smart contracts. No dedicated incorporated entity, registered office, governing law, or legal wrapper specifically attributable to Cooler Loans was identified.

An independent review likewise found no confirmed formal legal entity behind OlympusDAO or Cooler Loans. ToS, restrictions, KYC/AML, data protection: No Cooler-specific Terms of Service, user agreement, privacy notice, KYC/AML program, sanctions-screening policy, or data-protection controller was identified in the reviewed protocol documentation. The contracts are described as permissionless, and the documentation does not describe identity onboarding. This does not establish that every front end or ecosystem participant lacks compliance controls. Not verifiable as of October 11, 2026. Regulatory classification and risk: Functionally, Cooler is a protocol-native, treasury-funded crypto lending/credit facility.

Its legal classification could vary by jurisdiction and facts, including potential lending, investment-contract/securities, money-transmission, stablecoin, consumer-credit, or AML implications. No registration, licensing, legal opinion, or regulatory safe harbor was identified. The absence of a legal entity may reduce conventional claimant recourse while not eliminating exposure for developers, governance participants, front-end operators, treasury signers, or other identifiable contributors.

Olympus governance can change loan parameters and protocol modules, so “decentralized” does not equal legally risk-free. Warnings/enforcement/courts/sanctions: No regulator enforcement action, court case, or sanctions designation specifically against Cooler Loans, OlympusDAO, or a confirmed operating entity was identified in the reviewed searches. This is not a finding that no individual contributor or unrelated “Olympus” entity has legal exposure. No protocol-specific data-protection framework was identified. Legal structure vs. actual risk: Legal-entity opacity, permissionless access, absence of visible KYC/AML controls, treasury-linked lending, and governance-controlled parameters create material regulatory and recourse uncertainty despite transparent on-chain mechanics.

Stability

Cooler is not a stablecoin issuer; it is Olympus DAO’s lending product that lets users borrow USDS against gOHM collateral, so the protocol itself does not appear to issue its own stablecoin. The stablecoin used appears to be USDS, but a depeg history for the specific lending asset is not verifiable from the available sources, so depeg count, last depeg date, and max depeg % are all not verifiable as of 2026-10-11. The protocol can be marked as stable only in the narrow sense that no evidence was found of the protocol-issued asset depegging, but because there is no protocol-issued stablecoin and no verifiable depeg record for USDS in this context, the safer structured output is null/unknown where appropriate.

Cooler Loans is Olympus DAO’s gOHM-collateralized borrowing system, creating concentrated exposure to OHM/gOHM value, Olympus treasury liquidity, governance decisions, and contract execution. The April 4, 2025 Nethermind review found no critical/high issues in scope, but one low issue was fixed and one treasury-rounding issue was only acknowledged; current on-chain TVL, collateral concentration, and utilization are Not verifiable as of October 11, 2026.

strengths

I could not reliably identify a DeFi protocol named Cooler from the provided results, and the search results do not include protocol-specific documentation, audits, governance, or on-chain data for it. Because of that, the top 5 strengths are not verifiable as of 2026-10-11. The only result that appears possibly relevant is a generic cross-chain liquidity page from Eco, but it does not mention Cooler by name and cannot be used to attribute strengths to this protocol.

If you want, I can try again with one of these more specific identifiers:

  • the protocol’s contract address
  • the chain it is deployed on
  • the project’s full name (if Cooler is a nickname or shorthand)
  • a website, docs, or GitHub link
