About SpringSui
SpringSui is a liquid staking protocol on Sui built by the Suilend team: users deposit SUI for sSUI, staking rewards accrue into the receipt's value, the receipt stays usable in Sui lending and trading, and instant redemption means no unbonding wait.
It targets the liquidity loss of native staking, where SUI delegated to a validator is locked until unbonding and cannot join other strategies in the meantime. Liquid staking releases that opportunity cost. The risk is combinatorial: sSUI is widely used as lending collateral, so a sharp SUI decline triggers liquidations that hit the staking pool and lending markets at once, creating a negative loop. The protocol also offers validator selection, spreading delegation across nodes.
SpringSui, launched by Suilend, is a new liquid staking standard on Sui built on SIP-31 and SIP-33 protocol upgrades. Its first token, sSUI, enables users to stake SUI and receive a liquid token. A key milestone is the implementation of SIP-33, which allows instant unstaking for the entire supply, eliminating depeg risks and strengthening economic security. Suilend also open-sourced the SpringSui framework, enabling developers to create custom LSTs at no cost. Looking ahead, the roadmap includes a platform for anyone to create and manage their own LST, further driving liquid staking adoption across the Sui ecosystem.
SpringSui cemented its lead in Sui liquid staking through 2026: official data shows sSUI TVL around 79.8M SUI (about $155M), while FinanceFeeds reported TVL above $300M by mid-2026; in the Sui Insiders staking-protocol ranking on August 18, 2026, SpringSui topped the list with 492.1M SUI in stake volume. Its instant unstaking built on the SIP-31/SIP-33 upgrades (single-transaction redemption, no multi-day cooldown) became the key differentiator and was audited by Zellic and OtterSec.
