The Problem
Traditional liquid staking tokens depend on validator exit queues or secondary-market liquidity to exit, which can break the peg during stress events and create multi-day delays.
The Solution
SpringSui guarantees one-transaction redemption of sSUI back to SUI at any time, backed by the protocol's pool of StakedSui objects, removing both queue delay and depeg risk.
Why it Matters
First and only LST on Sui with native instant unstaking, codified as the open SpringSui Standard (SIP-33). Permissionless framework for other teams to deploy custom LSTs on the same audited base.
