DoubleZero Staked SOL

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

DoubleZero Staked SOL is a Solana stake-pool receipt associated with validators using the DoubleZero network. DefiLlama records about $113.6M and separately reports staking rewards plus withdrawal and management fees. Public evidence does not establish broader validator distribution or deeper exit liquidity than selected Marinade. This is category non-selection, not a flaw or incident finding.

Kill criteria: the events that revoke this verdict
• The selected provider in this category fails a kill criterion (these are the bench)
• The provider demonstrates a material improvement on the axis it lost on (validator distribution, liquidity depth, or distinct capability)

The research file

Selection, not disqualification

This is a relative choice within an already-accepted exposure category, not an allegation that the non-selected provider carries a disqualifying defect: every provider in the comparator set inherits the same slashing, validator, contract, oracle and token-liquidity risks, and a clean record alone is insufficient to win the selection. The mandate avoids holding multiple near-substitute liquid-staking tokens for the same native asset merely to diversify brands. The alternate reopens if the selected provider breaches a kill criterion or loses its comparative advantage in validator distribution, governance, liquidity, fees, or operating record.

Mechanism

The pool accepts SOL and issues a liquid receipt while stake is delegated through Solana stake-pool accounts. DoubleZero-connected validators may also earn network-related rewards, but the LST holder’s base return remains staked SOL net of pool fees.

Control and operating evidence

Stake-pool authorities choose validators and fees within the standard Solana program. DoubleZero publishes network economics and validator tooling, while DefiLlama identifies withdrawal and management fees. This memo does not infer an audit or complete incident-free record that the product has not published.

Exit consequences

Immediate exit depends on pool reserve or secondary liquidity; otherwise stake deactivation follows Solana epoch timing. Withdrawal fees reduce principal received, and the token can trade away from its SOL exchange value under stressed liquidity.

Why the class rule decides

Among close Solana LST substitutes, the selected provider won on validator distribution and liquidity. DoubleZero has not shown a superior client-relevant axis, so it remains on the bench. Review reopens with transparent allocation, independent security evidence and materially stronger stressed liquidity or distribution.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
