## Research summary

The assessment remains adverse until measurable research conditions are met. Marinade no longer operates the delegation mechanism that supported its earlier decentralization claims: an algorithmic rebalancer that spread stake across 400+ validators and scored decentralisation into every allocation. MIP-3, approved November 2024, retired it and moved all stake allocation to the Stake Auction Marketplace, a fixed auction that ranks validators by yield (commission plus bid) and fills top-down, with decentralisation reduced from an objective to a side constraint. Marinade's own validators API, read 2026-08-14, shows 46 validators holding mSOL stake, the top five at 41.1% and two hosting providers (Amarutu, Allnodes) near 40% combined. This is below the previously documented 200-validator monitoring condition. The comparison has also reversed: Jito's Steward now spreads stake in near-equal targets across the top 400 validators. The numbers weakened with the mechanism. mSOL liquid TVL fell from $1.43B in January 2025 to $181M at this review, per DefiLlama, and identifiable AMM depth is under $2M against the entry's $25M liquidity floor. The deeper routable figure used for that floor could not be reproduced, and the review remains open. An $8M market sale broke the peg about 15% intraday on 2023-12-12 into deeper books than exist today. Important facts still stand: five years on mainnet, no exploit, no loss of staked principal from any contract failure; audits by Kudelski, Ackee, Sec3, and Neodyme on a schedule that runs through 2026; a $250k Immunefi bounty. The 2023 depeg was a liquidity event, not a protocol failure, and delayed unstake worked throughout it. The SAM sandwich-validator episode was misconduct inside the delegated set, followed by the DAO blocklisting 50+ validators under MIP-9. Growth moved to Marinade Native ($212M) and the institutional Select line. The operation is healthy, but the mSOL float is not. This is not a finding of contract failure. It is the research state of a file whose deciding argument described a mechanism that had already been replaced. The primary API's 46 validators are those holding active mSOL stake, not the larger eligible or tracked set. Any client action or amount is a separate advisor decision.

## Observable review triggers

- Reopen only after active mSOL stake is distributed across at least 200 validators for two consecutive quarters, with the top five below 20% and any one hosting provider below 20%
- Reopen only after a proposed-size mSOL exit quotes below 50 basis points and delayed unstake completes within 7 days in three monthly tests
- Reopen only while mSOL liquid TVL exceeds $250M and independently reproducible executable exit depth exceeds the $25M liquidity floor
- Reopen only after the program upgrade authority, pause powers, and Council signers and 4-of-7 threshold are reproduced from current on-chain state
- Any active-validator count below 200, mSOL/SOL discount beyond 2% for 48 hours, delayed unstake beyond 7 days, or unaudited delegation change keeps the protocol rejected
