How Does Cooler Loans Work?

Lending|Risk C+|5 mechanisms|5 interactions

Cooler Loans is Olympus DAO's native lending product that enables gOHM holders to borrow USDS (Sky stablecoin) at a fixed 0.5% APR with no price-based liquidations — the Olympus Treasury itself is the lender, and all loans persist indefinitely regardless of gOHM market price. With $190M TVL, $127M in active loans, and no incidents since launching in July 2024 (V2 in May 2025), it is the largest DeFi lending product without price-triggered liquidations. Its C+ grade reflects the genuine novelty of its mechanism — which eliminates oracle attack risk at the cost of treasury solvency risk — combined with governance concentration on all key parameters and OHM's historically thin liquidity. The 'no liquidation' guarantee is backed by Olympus Treasury USDS reserves, not smart contract enforcement, making treasury solvency the critical risk factor that cannot be assessed from on-chain data alone.

Core Mechanisms

Lending > Treasury-Backed No-Liquidation Lending

Novel

Peer-to-treasury lending where Olympus Treasury is the lender; no price-based liquidations — loans persist indefinitely regardless of gOHM/USDS market price; default occurs only when unpaid interest exceeds governance-defined threshold

Eliminates price-based liquidation by anchoring LTV to treasury backing rather than market price. No major DeFi lending protocol at $100M+ TVL operates without price-triggered liquidations. The mechanism requires treasury solvency as the structural substitute for liquidation risk management.

Lending > Fixed Perpetual Rate

Novel

0.5% APR fixed by OCG Proposal 8; no market rate adjustment, no loan maturity date; interest accrues continuously and is collected without expiry

Fixed-rate lending exists (Notional, Term Finance) but always with defined maturities. A perpetual loan at a governance-fixed rate with no expiration is structurally distinct — it creates unlimited-duration exposure for the treasury lender at a rate that may not reflect future market conditions.

Lending > Governance-Set LTV

Novel

LTV set by LTV Oracle contract controlled by governance (currently ~2,961 USDS per gOHM, increasing by 0.1 USDS/day as a deflationary 'drip'); no external price feed; no price-based margin calls

Using governance-defined LTV instead of oracle-sourced collateral pricing eliminates oracle attack vectors but introduces governance capture risk as the primary parameter control mechanism.

Lending > Collateral Burn on Default

On interest-default, gOHM collateral is burned (permanently removed from supply) rather than liquidated via auction; 1% liquidation penalty; burning is deflationary for OHM supply

OHM burn on default is structurally unique to Olympus's monetary policy but mechanically is a deflationary collateral disposal — not a novel mechanism type.

Governance > Delegated Wallet Voting

DLGTE contract allows up to 10 wallet addresses to delegate to a single Cooler Loans position; enables multi-wallet borrowers to consolidate governance voting power into one on-chain loan

Multi-wallet delegation is a standard governance feature.

How the Pieces Interact

Treasury-Backed No-Liquidation LendingGovernance-Set LTVHigh

If OHM market price collapses below the governance-set LTV (~2,961 USDS/gOHM, implying gOHM ≥ ~$3,000 in USDS value), all borrowers have loans worth more than their collateral. No on-chain mechanism compels repayment or collateral top-up. The Olympus Treasury absorbs the full mark-to-market loss until either OHM price recovers or borrowers voluntarily default (triggering burn). A large sustained OHM price decline would leave the treasury with $127M+ in non-performingpositions and burned collateral with no recovery.

Fixed Perpetual RateTreasury-Backed No-Liquidation LendingHigh

The Olympus Treasury is the sole lender for all $127M in outstanding loans at a perpetually fixed 0.5% APR. If USDS market rates rise significantly above 0.5%, the treasury is lending at below-market rates indefinitely, subsidizing borrowers. The perpetual structure means the treasury cannot exit or reprice existing loans — creating lasting underpayment exposure unless governance votes to change the rate (which would not apply retroactively to existing loans per current design).

Governance-Set LTVFixed Perpetual RateMedium

All key parameters — LTV, interest rate, default thresholds — are controlled by OCG governance votes. A single successful governance proposal can set an unrealistically high LTV (enabling massively undercollateralized borrowing against the treasury), reduce the rate to 0% (eliminating treasury revenue), or adjust default thresholds to prevent any defaults regardless of non-payment. Governance capture by a large OHM holder or coordinated whale voting creates systemic parameter risk.

Fixed Perpetual RateCollateral Burn on DefaultMedium

When interest defaults trigger gOHM burn, the burned supply creates deflation in OHM/gOHM outstanding. In a mass-default scenario (OHM price collapse driving simultaneous non-repayment across many borrowers), large-scale gOHM burning reduces the collateral base used for future Cooler Loans, potentially reducing the protocol's TVL capacity and treasury utility permanently.

Treasury-Backed No-Liquidation LendingCollateral Burn on DefaultMedium

The perpetual loan structure with no maturity means the treasury must maintain $127M+ in USDS liquidity indefinitely. If the treasury redeploys USDS into illiquid yield strategies, a sudden demand for loan repayment plus new borrowing drawdowns could create a USDS liquidity crunch. In the worst case, treasury USDS depletion could prevent new loans while existing borrowers cannot be forced to repay — freezing the system.

What Could Go Wrong

  1. The 'no-price-liquidation' guarantee holds only as long as the Olympus Treasury's USDS reserves exceed all outstanding loan balances ($127M+). If OHM price collapses enough that treasury backing per gOHM falls below the governance-set LTV (currently ~2,961 USDS/gOHM), borrowers have no economic incentive to repay — they keep their USDS while the treasury absorbs losses. The treasury's solvency is the protocol's only collateral backstop.
  2. All key parameters — interest rate (0.5% APR), LTV (~2,961 USDS/gOHM), and default thresholds — are set by Olympus Community Governance (OCG) votes. A single governance vote can change any parameter, including setting an unrealistically high LTV or reducing the interest rate to zero. Governance capture or error poses a systemic risk to all outstanding loans.
  3. gOHM has a 24-hour trading volume of approximately $18K against a $245M market cap — extremely thin liquidity. On-default, gOHM collateral is burned rather than auctioned; but borrowers who need to exit their gOHM position outside of Cooler Loans face significant market impact on thin order books.
  4. The perpetual loan structure (no maturity date) means the Olympus Treasury must maintain continuous USDS liquidity for all $127M in outstanding loans indefinitely. Any treasury reallocation to non-liquid assets reduces the USDS buffer, concentrating liquidity risk in a single asset.

OHM Price Collapse Rendering $127M in Loans Undercollateralized

Moderate

Trigger: gOHM market price falls below 2,961 USDS (the current governance-set LTV) — approximately equivalent to OHM at ~$14-16 depending on staking ratio — making all outstanding Cooler Loans economically undercollateralized

  1. 1.OHM market price falls to $12-15, pushing gOHM value below 2,961 USDS per gOHM All Cooler Loans borrowers hold USDS loans worth more than their gOHM collateral; no economic incentive to repay principal; rational borrowers stop paying interest to trigger 1% liquidation premium burn rather than voluntarily repaying full principal
  2. 2.Mass interest non-payment triggers gOHM burn cascade across all defaulting loans Large fraction of gOHM supply burned; Olympus Treasury receives no USDS recovery; $127M+ in outstanding loans becomes non-recovering debt absorbed by the treasury
  3. 3.Treasury USDS reserves drawn down by non-recovered loans; Yield Repurchase Facility cannot buy OHM to support price OHM price support mechanisms disabled; further OHM price decline accelerates as remaining treasury backing falls
  4. 4.Remaining Cooler Loans borrowers and new borrowers see expanding gOHM undervaluation at governance-set LTV; protocol becomes a mechanism for draining the treasury Governance forced to emergency-vote to reduce LTV or suspend the protocol; if governance fails to act quickly, treasury USDS is depleted
  5. 5.Treasury USDS below minimum operational threshold; Olympus DAO enters insolvency management OHM price collapses toward backing value (treasury assets per OHM); remaining holders receive fractional redemption against remaining treasury assets
