Sanctum Reserve Review 2026: Instant Exit Pool for Solana LSTs

Sanctum Reserve, also called the Sanctum Reserve Pool, is a pool of idle SOL that accepts staked SOL and gives SOL from its pool in return. It is part of Sanctum, a Solana staking infrastructure project whose homepage describes Solana liquid staking, custom LSTs, white-label validators, a transaction delivery service called Gateway, and a DevOps platform called Ironforge.

DefiLlama lists the Reserve under Yield on Solana, with about $59.2M in TVL. TVL fell 6.6% over the last seven days. It has been tracked since August 2023, and the listing shows two audits and a SANC token.

The Reserve is mainly useful as liquidity infrastructure for LST holders, not a place to farm yield. The project does not publish fee levels, so we have not scored that.

Liquid staking tokens (LSTs) represent SOL that is staked with a validator. Unstaking normally means waiting for the end of a Solana epoch. The Reserve covers that gap: it holds idle SOL, and anyone with an LST can swap it for SOL from that pool.

The pool accepts the staked SOL and releases SOL in return. The pool then deals with the staked position, which turns back into SOL over time. A user who wants out right away pays for that convenience, though the project does not state the price.

The Reserve works alongside Sanctum's router and Infinity pool, which handle swaps between different LSTs. The Reserve serves as a deep backstop of plain SOL for those exits.

The project does not publish a fee for swapping through the Sanctum Reserve. Users would see the rate and any cost in the quote inside the Sanctum interface before approving a transaction.

As with any Solana transaction, a small network fee applies. Public sources give no figure for it. The Q2 2026 results mention revenue lines for Sanctum Reserve and Router, which suggests the pool earns from usage, but the fee rate is not stated.

DefiLlama lists two audits for the project, but the project does not name the auditors or describe the findings. The Reserve is non-custodial in the usual DeFi sense, as users keep their own wallets and approve transactions. They still carry smart-contract risk, Solana network risk and the risk that swap terms move with pool conditions.

Public sources mention no hacks or incidents, but that is not a guarantee of safety. Check the documentation and any audit reports yourself, and do not put in more than you can afford to lose. This is not financial advice.

This is for Solana users who hold LSTs and sometimes need to turn them into SOL quickly, and for readers who want to understand how liquid staking exits work. It is less relevant to people who only want a simple staking yield, who may prefer Sanctum's own staking product.
