Lending · SPK · $3.7B TVL. Spark is Sky's lending subDAO — an Aave-lineage money market wired directly into the USDS ecosystem, deploying Sky's balance sheet as deep, protocol-owned liquidity. At $3.7B TVL it functions less like a startup lender and more like the credit arm of an established stablecoin issuer.
Solvency screens at A. The ~3x sustainability ratio benefits from Sky's direct liquidity provision, drawdown has been moderate, and the risk framework is inherited from the most battle-tested collateral operation in DeFi. Unlock pressure around 5% is the only middling input as SPK distribution proceeds.
Legitimacy screens at A: audits are solid, the team executes within Sky's published roadmap, and delivery has been consistent. Governance scores 5/10 — as a subDAO, Spark's autonomy is real but bounded, and accountability routes through Sky's layered Endgame structure.
Growth screens at BB. A comparatively shallow TVL decline (~15%) and decent momentum from the Sky ecosystem integration are offset by 15% category share in lending's crowded field. Its growth is structurally tied to USDS adoption.
Composite BB. Effectively a leveraged bet on Sky's ecosystem executed with strong engineering. A full rating would analyze it jointly with Sky, since its credit profile cannot be separated from its parent's.
"A chain is as strong as its weakest link." The conservative composite takes the weakest dimension and inherits any notching cap, so a single structural weakness cannot be diluted by strength elsewhere.
