Sanctum Reserve is the SOL-and-stake liquidity pool that lets Solana LST holders unstake instantly. Users provide staked SOL and receive native SOL from the Reserve at a small spread; the protocol’s bots later resolve the staked-SOL position back into native SOL at the next epoch.
The Reserve is what makes “instant unstaking” possible across Sanctum’s LST ecosystem and is one of the protocol’s largest TVL surfaces. CLOUD is the governance token.
