Sanctum Review: LST Liquidity, Routing & Validator Risk

Sanctum isn’t a single-issuer LST like Jito or Marinade — it’s infrastructure that lets projects launch LSTs and lets holders swap between different LSTs, solving liquid staking’s fragmented-liquidity problem. Its official Explore directory showed 237 Solana LSTs on September 26, 2026, including INF, JupSOL, bpSOL, bonkSOL, and BulkSOL. If you hold an LST from a smaller or validator-specific issuer, Sanctum’s unified liquidity layer can be useful, but the underlying token still determines much of your risk.

See our head-to-head comparisons: Sanctum vs Jito and Sanctum vs Marinade.

What Sanctum is actually used for

Sanctum is used both by holders swapping between LSTs and by projects or validators who want to launch their own LST without building liquidity infrastructure from scratch.

Sanctum’s swap fees versus underlying LST yield

Swap fees within Sanctum’s liquidity layer vary by LST pair and pool; check the app for current rates. Sanctum doesn’t charge a separate fee for the underlying staking rewards of whichever LST you hold — that’s set by the individual LST’s issuer.

What Sanctum solves, and what it doesn’t

• Pro: solves a real problem — before Sanctum, smaller LSTs had thin, fragmented liquidity that made entering or exiting expensive.
• Pro: lowers the barrier for validators and projects to launch their own LST.
• Con: your risk exposure depends on which underlying LST you hold, not just the aggregation layer — a smaller, validator-specific LST carries its own validator-concentration and liquidity risk.
• Con: because it enables many small issuers, the number of available LSTs varies in quality and track record more than the largest few.

Sanctum’s role in the long tail of Solana LSTs

Sanctum has become significant infrastructure specifically for the long tail of Solana LSTs beyond the largest few issuers, addressing a real liquidity fragmentation problem that exists as more validators and projects launch their own staking tokens. The directory is a discovery tool, not a safety ranking: an LST with almost no stake or secondary liquidity needs a different risk assessment from a major pool token.

Why your risk depends on the LST, not just Sanctum

Because Sanctum aggregates liquidity across many different LSTs, your risk exposure depends partly on which underlying LST you hold or receive — a smaller, validator-specific LST carries different validator concentration and liquidity risk than a large, established one. Read our liquid staking guide to understand what to check about any specific LST before holding it, beyond the aggregation layer itself.

What to verify before using Sanctum

Sanctum’s aggregation model is documented publicly and its LST and pool state can be checked on Solana. The important verification happens one level lower: identify the exact LST, then inspect its validator exposure, redemption path, liquidity, and exchange rate before holding it, because Sanctum does not erase the underlying asset’s risks.
