JPool

JPool issues JSOL through the standard Solana stake-pool design and publishes an explicit validator-allocation program. DefiLlama records about $103.5M. JPool’s exclusion of superminority and oversized validators is credible comparative evidence, but part of its allocation also rewards community status and direct-stake matching rather than pure risk-adjusted performance. It remains a legitimate bench LST, not an unsafe protocol.

Review triggers: events that reopen the verdict
• The selected provider in this category fails a review trigger (these are the bench)
• The provider demonstrates a material improvement on the axis it lost on (validator distribution, liquidity depth, or distinct capability)

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

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 review trigger or loses its comparative advantage in validator distribution, governance, liquidity, fees, or operating record.

Mechanism

SOL deposits mint JSOL, which appreciates as delegated validators earn inflation and MEV rewards. JPool allocates slots through community-good, direct-stake and performance tiers; validators post a JSOL bond and must meet commission, blacklist and stake-concentration limits.

Control and operating evidence

JPool publishes inclusion, removal, bond and allocation rules, improving the evidence beyond a generic stake pool. The manager still administers the validator list and program authorities. This comparative memo does not claim a complete independent security or incident review.

Exit consequences

Users can seek instant unstaking for a higher fee or delayed exit at an epoch boundary. Available instant liquidity and any DeFi lock determine how much JSOL can be exchanged immediately; market sale can occur at a discount.

Why the class rule decides

The category selected Marinade rather than holding multiple near-substitute Solana LSTs. JPool’s published decentralization rules make it a serious bench candidate, but do not yet justify replacing the selected provider on distribution, liquidity and operating record together. Those metrics can reopen the comparison.

Research, shelf, and client selection

This record found no disqualifying defect, but favorable research does not create firm-shelf eligibility or a client recommendation. Firm policy must separately admit the product; client purpose and constraints then determine the candidate set; and the advisor records any selection and amount.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
