[SIP2.35] Add Gearbox WETH Pool curated by KPK to Lazy Summer ETH Lower-Risk Vault

Governance Summer Improvement Proposals [SIPs]

Thanks for reviewing this integration. We’d like to share additional transparency on the current risk profile of the kpk-curated Gearbox WETH pool, as the strategy has evolved significantly from the earlier Gearbox configuration live on Summer.fi.

Summer.Fi already has exposure to Gearbox via the historical Chaos Labs WETH pool, in the Low Risk ETH ARK. The kpk pool is the next-generation version on the latest Gearbox architecture, with:

  • A reduced and ETH-focused collateral universe
  • Safer unwinding mechanics via native ERC4626 and ERC7540 vault withdrawals (not dependent on AMM liquidity)
  • Dual-oracle pricing and staleness safeguards across all collateral types, with modernised oracle infrastructure
  • Active ongoing maintenance and parameter refinement
  • A dedicated Insolvency Monitor that can autonomously pause the pool when anomalies are detected

More context on the launch:

Current risk posture

  • Lending exposure is fully concentrated in liquid, ETH collateral only (wstETH, rETH, rsETH, weETH, ezETH and ETH+)
  • Strict risk-tiering limits long-tail exposure (e.g., RE7LRT capped at 150 ETH → sufficient to unwind existing positions without enabling new leverage))
  • Expected liquidity has remained ~3000+ ETH since shortly after launch, even during the sustained utilisation between ~74 and 90 % → Lenders retain reliable exit capacity under normal market conditions
  • 90+ unique lenders → diversified funding base and reduced concentration risk
  • Configuration improvements and oracle updates are tracked publicly via the change log

Dual-oracle safety model
Each collateral asset uses both a market-price oracle (Chainlink or RedStone) and a fundamental “reserve oracle” that reflects underlying redemption value. This architecture mitigates collateral manipulation, protects against LST depeg scenarios, and ensures healthy collateral valuation during volatility events.

wdwstETH collateral
We’d like to provide more light on the wdwstETH token, mentioned by @BlockAnalitica in the original kpk RFC. wdwstETH is a staked phantom token that enables safe, native unwinds of rsETH positions via the underlying withdrawal queue, avoiding reliance on AMM liquidity. It never leaves the Gearbox position and uses discounted reserve-oracle checks to ensure borrower health. Hence, it does not expand the asset universe of Summer.fi beyond normal exposure to rstETH.

Next Steps
We are making our Gearbox Risk Dashboard public shortly, offering live visibility into collateral, utilisation, liquidity coverage and concentrations - similar to our Morpho vault transparency. We’re happy to supply any additional data needed for BA Labs to set final parameters at SIP stage. Thanks again for the constructive governance process. Looking forward to the vote.
