Aave Governance We move to freeze $279M in osETH Collateral

A proposal before Aave governance would freeze roughly $279.4 million worth of osETH collateral on the lending protocol, unless StakeWise persuades token holders to grant a separate risk assessment first.

The freeze itself is mechanical. It would set osETH's borrowing limit within Aave's ETH-correlated efficiency mode, E-Mode, to zero. Existing borrowers could still repay or migrate their positions, with withdrawals governed by each position's constraints. The proposal identifies wstETH, weETH, cbETH and WETH as replacement collateral already live in the same E-Mode, so borrowers can swap collateral without first repaying all their WETH debt.

The numbers come from LlamaRisk's Nov. 9 analysis, which valued osETH collateral at $279.4 million against an estimated $256.6 million of WETH debt, attributed proportionally across each borrower's collateral mix. The adviser put leverage at roughly 14 times, against a 93% loan-to-value limit for osETH in E-Mode. Concentration is the crux: the 10 largest positions account for 66% of the attributed debt, which makes the treatment of existing positions central to any transition.

On-chain data tracks the picture. Independent daily reserve snapshots show 122,900 osETH deposited on Nov. 9 and 122,400 on Nov. 11. Aavescan's 0.0074-osETH loan balance in both rows measures borrowing of osETH itself, not the much larger WETH debt backed by the token.

What is StakeWise's counterargument?

StakeWise's Dmitri has asked governance for a separate vote that would weigh his protocol's track record against Aave's lending-risk criteria and give StakeWise time to address concerns before reassessment. He said StakeWise has experienced no hacks and no validator slashings since January 2021, and described immutable, native leverage contracts that return borrowed ETH directly from validators.

How would the transition be priced?

LlamaRisk's static analysis found that cutting liquidation thresholds by 2% to 5% would push most collateral in the highly leveraged rsETH and osETH loops into liquidation eligibility. The osETH category also contains other ETH collateral, so a shared threshold can't cleanly target it.

Instead, the adviser proposes issuer engagement and natural unwinding, with monthly progress reports. If exposure declines, no further measure applies. If migration fails to reduce it, a WETH base-borrow-rate increase remains the last resort: up to 1%, in 0.5% steps no more than monthly. Proposed rebates would offset the increase for WETH borrowers holding neither rsETH nor osETH, and a reserve-factor adjustment would keep the supply rate constant.

Where does Aave V4 fit in?

Aave V4's hub-and-spoke architecture offers a different way to allocate those costs, though neither the proposal nor the V4 overview names a specific osETH spoke or premium. Hubs share liquidity; spokes carry local risk settings and limits on how much liquidity they can draw or add. A User Risk Premium charges borrowers according to the collateral needed to cover their debt. Aave's position-conditions documentation gives a generic example: a 50% premium turns a 5% base rate into 7.5%.

For borrowers, an orderly transition depends on a usable route and acceptable terms. For lenders, the question is whether governance can cut exposure while pricing what remains. Whether token holders grant Dmitri his separate assessment, and what migration terms they approve, will decide how that trade-off lands for osETH.
