## The memo

REJECTED ON UNDISCLOSED LEGAL AND CROSS-CHAIN ADMIN STRUCTURE. Spark Liquidity Layer is the capital-allocation plumbing beneath Spark Savings' sUSDS product, routing USDS, sUSDS, and USDC across lending markets, ERC-4626 vaults, DEXs, and staking venues on eight chains under Sky ecosystem governance. Despite the eight-chain footprint, roughly 96% of tracked capital sits on Ethereum mainnet today, meaning the cross-chain admin surface is currently more a governance exposure than a large realized capital one — a genuine, favorable finding this review credits. But this review could not confirm the operating legal entity's name or jurisdiction, any KYC or geographic eligibility policy, or how the protocol's admin, relayer, and freezer roles are actually structured chain by chain — whether each of the eight deployments has its own local pause authority or all control flows from Ethereum mainnet governance via cross-chain messaging is undisclosed in any source this review could access.

## What would reopen the file

- 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
