## Research summary

This review rejects Spark Liquidity Layer because it does not disclose its legal or cross-chain admin structure. Spark Liquidity Layer is the capital-allocation system beneath Spark Savings’ sUSDS product. It routes USDS, sUSDS, and USDC across lending markets, ERC-4626 vaults, DEXs, and staking venues on eight chains under Sky ecosystem governance. Despite that eight-chain footprint, roughly 96% of tracked capital sits on Ethereum mainnet today. The cross-chain admin structure is therefore more of a governance exposure than a large current capital exposure. This review credits that genuine, favorable finding. But it could not confirm the operating legal entity’s name or jurisdiction, any KYC or geographic eligibility policy, or how the protocol assigns its admin, relayer, and freezer roles on each chain. No source this review could access discloses whether each of the eight deployments has its own local pause authority or whether all control comes from Ethereum mainnet governance through cross-chain messaging.

## Observable review triggers

- The operating legal entity's name and incorporation jurisdiction are publicly disclosed
- Per-chain admin, relayer, and freezer authority structure is disclosed, including whether each deployment has independent local control
- A specific KYC and geographic eligibility policy is published
- Non-Ethereum chain TVL concentration is monitored, with this entry reopened for reassessment if a non-Ethereum deployment grows to material size before the admin-structure gap is closed
