Sui staking: APY, 24-hour epochs and the storage fund
What SUI staking pays, how 24-hour epochs make it one of the most liquid staking models, where the yield comes from, and what replaces slashing.

Staking Sui pays low single digits before commission, on the model set out in the Sui documentation, and compensates with the fastest exit in major staking: unstaking completes at the next 24-hour epoch boundary. Principal is never slashed.
How staking works on Sui
Sui uses delegated proof of stake with 24-hour epochs. From 1 SUI you delegate to a validator via your wallet; the stake activates at the next epoch, earns per epoch, and deactivates the same way. Validator commission and performance determine your net rate.
Where the yield comes from
Sui’s rewards are a transition design: pre-allocated stake subsidies released on a decreasing schedule carry the yield while the network is young, with gas fees and the storage fund intended to take over as usage grows. That makes today’s rate part subsidy, part usage, and the subsidy component has an expiry date built into its schedule.
Unstaking and lock-ups
At most 24 hours. There is no unbonding queue and no dead time worth planning around; a Sui staking position is close to liquid in practice. Only Cardano’s no-lock model is more flexible among the majors.
What can go wrong
- Reward strips, not slashes. The tallying rule can zero a validator’s epoch rewards; you lose yield for the period, never principal.
- Subsidy decay. Part of today’s yield is bootstrap subsidy on a decreasing schedule; the sustainable rate depends on fee growth.
- Low absolute rate. At a low single-digit rate, commission choices and validator uptime eat a visible share of the return.
Sui staking vs THORChain bonding
Sui is the liquidity extreme: exit in a day, no slash risk, modest and partly subsidized yield. THORChain bonding is the income extreme: fee-sourced, historically much higher, with whitelist entry, churn-timed exits and real slash exposure. The two are compared directly at THORChain vs Sui staking, and the bonding model at THORChain bonding.
风险概览
你的回报取决于所选的节点或验证者。对方掉线、配置出错或作恶都会让你损失奖励，在部分网络上还会损失部分本金。
退出并非即时：next epoch boundary (≤24 h)。
实际影响最大的是 SUI 的价格波动，任何质押收益率都无法抵消。

What is the current APY for staking Sui?
Delegation has been paying low single digits before commission. The rate depends on validator performance, commission, gas fee volume and the stake-subsidy schedule.
How long does unstaking take on Sui?
Until the next epoch boundary, and Sui epochs last 24 hours, so at most a day. This makes Sui one of the most liquid native staking models among major chains.
What happens if my Sui validator misbehaves?
Not of principal. Instead of burning stake, Sui's "tallying rule" lets validators score peers and strip a poorly performing validator of its rewards for the epoch; delegators feel it as missed yield, never as lost capital.
Where do Sui staking rewards come from?
A combination of stake subsidies (a pre-allocated pool released on a decreasing schedule to bootstrap the network) plus gas fees from actual transactions. The 10 billion SUI cap never moves, but the subsidy still dilutes: it moves tokens out of a non-circulating pool and into circulation, which affects a holder the same way new issuance would, with the storage fund compensating validators for holding historical data. Over time the design intends fees to replace subsidies.
What is the minimum to stake SUI?
The protocol minimum is 1 SUI, delegated from a self-custody wallet to any validator. Rewards accrue per epoch and compound automatically until you withdraw the stake.
