Leveraged yield farming has a long history of catastrophic failure, usually because the leverage and the strategy shared a pool and one bad position took everyone down. Gearbox isolates each position in its own credit account — a separate contract holding one user's collateral and borrowed funds.
How the safety model works
Credit accounts can only interact with whitelisted protocols and assets, so borrowed capital cannot be deployed into arbitrary contracts. Health factors are monitored per account and liquidated individually. Passive lenders supplying the borrowed capital are exposed to the aggregate quality of those liquidations rather than to any single position.
What leverage does to yield risk
A 5% strategy at three times leverage is not a 15% strategy — it is a 15% strategy where a 10% adverse move in the underlying wipes the position. Yield strategies fail through depegs, bad harvests and oracle glitches, all of which are survivable unlevered and terminal levered. Users consistently underestimate this.
Record
Extensive audits, a long-running bug bounty, and no protocol exploit to date across several years. The complexity is high, which is the standing concern for any composable leverage system.
Who should use it
Experienced users running specific levered strategies who have modelled the liquidation scenario, and passive lenders wanting yield from a well-designed borrowing market. Not a product for anyone who would describe their strategy as farming.
