Using stSUI in DeFi

Composability

stSUI is a standard Sui token. Any DeFi protocol that accepts Sui-native tokens can use it.

SUI in a wallet earns nothing. Staked SUI is locked. stSUI earns rewards and stays usable.

stSUI in AlphaFi LEND

stSUI is supported as collateral on AlphaFi LEND. Three options:

1. Hold stSUI — earn staking rewards passively
2. Supply to LEND — earn supply APR on top of staking rewards
3. Borrow against stSUI — use it as collateral to borrow other assets

Option 3 is powerful: borrow USDC against your stSUI, deploy the USDC elsewhere, and your stSUI keeps earning staking rewards the whole time.

See the LEND section for supply rates, borrow rates, and liquidation parameters.

stSUI in AlphaFi Strategies

stSUI is used in several Strategy vaults, including stSUI vault, stSUI–SUI CLMM vaults etc. The tight peg between stSUI and SUI keeps impermanent loss minimal.

These vaults layer trading fees and rewards on top of staking yield.

Other Sui DeFi

stSUI is integrated across the Sui ecosystem — DEXs, lending, yield aggregators.

Holding vs deploying

Approach	Yield	Risk
Hold stSUI in wallet	Staking only	LST risk only
Supply to LEND	Staking + supply APR	LST + lending
Borrow against stSUI	Staking + leverage	LST + lending + liquidation
Strategy vaults	Staking + LP fees + rewards	LST + vault + IL (where applicable)

More yield = more risk. The right choice depends on your goals.
