Is Inverse Finance FiRM Safe?
Risk Grade: B- (33/100)
Inverse Finance FiRM is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — innovative fixed-rate design with strong security improvements after 2022 exploits, balanced against untested DBR mechanism and historical vulnerability pattern.
Inverse Finance FiRM is a fixed-rate lending protocol that uses a novel DOLA Borrowing Rights (DBR) mechanism to let borrowers lock in interest rates. With $48M TVL and a redesigned architecture after two 2022 exploits on its predecessor, its B- grade reflects innovative design improvements (dual oracle, personal collateral escrows) offset by the untested nature of the DBR mechanism and the protocol's exploit history on earlier products.

Key Risks for Inverse Finance FiRM Users
Inverse Finance suffered two oracle manipulation exploits in 2022 totaling $21M on its old Anchor product. While FiRM is a complete redesign with improved oracle protections, the historical pattern of vulnerabilities is a risk factor.
FiRM uses DOLA Borrowing Rights (DBR) tokens that decay over time to maintain your borrowing position. If the DBR market becomes illiquid or prices spike, you may be forced to close your position even if your collateral is healthy.
All borrowing on FiRM is in DOLA stablecoin. If DOLA loses its peg, your borrowing costs could change unpredictably.
Top Risk Factors
- •Historical oracle manipulation exploits — Inverse Finance suffered two oracle manipulation attacks in 2022 ($15.6M and $5.8M) on its now-retired Anchor product. While FiRM was redesigned with a dual-oracle system (Chainlink + 48h PPO low), the pattern of oracle-related vulnerabilities warrants continued scrutiny.
- •DOLA Borrowing Rights (DBR) sustainability — DBR is a novel DeFi primitive that decays over time and must be replenished to maintain borrowing positions. If DBR market liquidity dries up or prices spike, borrowers could face forced position closures.
- •Personal Collateral Escrow complexity — FiRM uses per-user escrow contracts to isolate collateral, preventing co-mingling. While this improves safety, the proliferation of individual contracts increases smart contract surface area.
- •DOLA stablecoin peg dependency — all borrowing on FiRM is denominated in DOLA. A DOLA depeg event would disrupt borrowing costs and potentially trigger liquidations.
