Hylo LSTs

Hylo LSTs is below the size floor, so we will not open an individual review until it clears that floor. It is the LST-backed reserve for Hylo’s Solana-native dual-token system, not a standalone liquid-staking token. The reserve backs hyUSD, a stablecoin, and xSOL, a dynamically leveraged SOL claim that absorbs reserve volatility. It held about $15.0M on 2026-08-15. Its size keeps the review closed, and the survey label does not show that hyUSD is cash-like or that xSOL is ordinary staked SOL.

Review triggers: events that reopen the verdict
• TVL sustained above the retired TVL threshold for 30 days

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

Mechanism applicability

Hylo documents one LST collateral pool that supports two liabilities: $1-target hyUSD and xSOL, whose remaining net asset value creates dynamic leveraged SOL exposure. xSOL absorbs SOL price moves to protect hyUSD. This corrects the old description of the product as a standalone LST. The reserve remains below the size floor, so we will not open an individual review until it clears it.

Current observation and perimeter

The DefiLlama API read on 2026-08-15 reported approximately $15.0M on Solana and labelled the adapter Liquid Staking. Hylo’s primary documentation instead defines the product under review as a stablecoin and a leveraged token backed by Solana LSTs. That structure will guide the individual review if the reserve clears the size floor.

Control and exit applicability

Hylo uses SOL price inputs and stake-pool value calculations to price the reserve’s LSTs. Mint and redemption fees change with collateral health. Below stated thresholds, the system can convert stability-pool hyUSD into xSOL, and xSOL redemption costs more. Exit depends on reserve backing, valuation programs, the collateral ratio, dynamic fees and external liquidity.

Why the class rule decides

The shared v1 below-materiality dossier sets the rule. Reopen the individual review after reproducible reserve TVL stays at or above the size floor for 30 days. Then review hyUSD and xSOL separately for reserve concentration, LST depegs, oracles and controls, collateral stress, stability-pool conversion, fees, audits and incidents, governance, and proposed-size redemption against unleveraged staking and stable-value alternatives.

Research status

This is a capacity-unproven record for Hylo LSTs, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.

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.
