Jupiter Staked SOL

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

Jupiter Staked SOL is a liquid staking token on Solana issued by the Jupiter exchange. It held about $395M at the 2026-08-14 survey. Solana liquid staking tokens are close substitutes, so we made the choice once, comparatively, and selected Marinade, preferring its delegation across more than 100 validators over JupSOL’s Jupiter-centered validator exposure. JupSOL is non-custodial, uses the audited SPL stake-pool design and has multisignature upgrade control; no disqualifying protocol flaw was found. This is an honest category-reviewed disposition—JupSOL was not selected, not individually rejected as unsafe.

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

The mechanism

JupSOL is a non-rebasing SPL stake-pool token. Deposited SOL is delegated through Sanctum’s stake-pool infrastructure, while staking rewards, MEV and designated priority fees increase the JupSOL/SOL exchange rate. Jupiter documents zero validator commission and a 5% fee on base rewards, split between Sanctum infrastructure and the Jupiter DAO treasury. Downstream use as lending collateral adds separate liquidation risk.

Control and operating record

The SPL stake-pool program authority is controlled by an 11-member ecosystem multisig; Jupiter says the Sanctum management authority cannot access pool funds. Sanctum handles day-to-day delegation. Those are meaningful controls, and no loss event identified in this applicability review changes the category result. The residual issue is concentration of economic stake around Jupiter’s validator strategy, not custody by Jupiter.

The exit

A holder may sell JupSOL immediately through available liquidity or request delayed unstaking. Jupiter says direct pool unwrapping can carry a 0.1% withdrawal fee and delayed unstake converts JupSOL into a deactivating stake account for roughly two days. A DEX sale substitutes market depth and discount risk for that epoch-bound process.

Why the category decision stands

Marinade applies one transparent delegation strategy across more than 100 validators; JupSOL is deliberately tied more closely to Jupiter’s validator economics. The standing comparative choice prefers the broader validator distribution. This is not an individual approval review. JupSOL moves first off the bench if Marinade fails a kill criterion or if JupSOL materially broadens validator distribution or supplies a distinct capability.

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

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.
