Is Suilend Safe?
Risk Grade: B- (34/100)
Suilend is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — dominant lending position on Sui, but the chain's thin liquidity means a sharp crash could overwhelm liquidation infrastructure
The largest lending protocol on Sui, where you deposit crypto to earn interest or borrow against it. It holds $630M with $6M in funding and also built SpringSui, a liquid staking system for SUI tokens. Its B- grade reflects rapid growth on a young blockchain where DeFi infrastructure is still maturing.

Key Risks for Suilend Users
If SUI drops 40%+ in a day, mass liquidations could overwhelm the thin on-chain liquidity. Liquidation bots stop bidding when it is unprofitable, bad debt piles up, and depositors cannot withdraw
The sSUI liquid staking token is widely used as collateral. A bug in SpringSui could cause sSUI to lose its peg, triggering cascading liquidations that deepen the depeg in a vicious circle
Suilend depends entirely on the Sui blockchain. The chain is young, the DeFi ecosystem is thin, and oracle coverage for newer Sui tokens is limited. Prices could be stale or manipulated
Top Risk Factors
- •Cascading liquidations during SUI price crashes could generate bad debt across lending pools due to thin on-chain liquidity
- •SpringSui LST (sSUI) depeg risk creates correlated collateral exposure across the Suilend lending ecosystem
- •Sui ecosystem concentration risk — protocol depends on a single L1 chain with limited DeFi infrastructure maturity
