Sui · Narwhal · Bullshark Consensus
Sui is a delegated Proof-of-Stake chain built on the Move language, with 24-hour epochs and one of the shortest unbonding windows in PoS. Base APY is modest (~3.8%) because the network is over-staked — 81% of circulating SUI is bonded. The real yield story lives in Sui’s DeFi stack: liquid staking tokens, lending markets, and LP strategies that stack on top of native rewards.
Ways to Stake
Sui staking is delegation-only for most users: you pick one validator per stake object. Running a validator requires a large self-bond and operational overhead.
Pick a validator in your wallet, submit one transaction, done. Rewards auto-compound into the stake object each epoch (24h). No bond between SUI and validator on slashing — Sui has no slashing today.
Deposit SUI with Aftermath (afSUI), Haedal (haSUI), or Volo (vSUI) to receive a yield-bearing ERC-20-equivalent. Keeps your capital tradeable and usable as DeFi collateral while it earns staking rewards.
Active validator set is capped at 150 and requires a significant self-bond plus hardware, networking, and monitoring. Earns commission on delegated stake. Best suited to infrastructure providers, not individual stakers.
Liquid Staking Tokens
Sui LSTs all work the same way: you deposit SUI, the protocol delegates it across a curated validator set, you hold a token that accrues value as staking rewards come in. Each epoch (~24h) the exchange rate ticks up.
Yield Farming
Sui’s DeFi stack is young but dense: a couple of major DEXs (Cetus, Kriya, Aftermath), several lending markets (NAVI, Scallop, Suilend), and a CDP protocol (Bucket). Here are the combinations worth knowing.
Provide concentrated liquidity on Cetus’s haSUI/SUI pool. Because the pair tracks, set a tight price range around the current ratio to amplify fee capture. Earn swap fees plus CETUS incentives while the LST half continues to accrue staking rewards.
Supply haSUI or afSUI on NAVI as collateral, borrow SUI, swap to more LST, repeat. Each loop stacks staking yield on top of borrow rate spread. Watch the health factor — LST depeg is the main liquidation trigger.
Deposit SUI or an LST on Scallop and earn supply APY plus SCA token emissions. Scallop’s sCoin receipt is itself composable — use it as collateral elsewhere for a second income layer.
Suilend (by the Solend team, ported to Sui) is the other major Sui lending market. Similar playbook to NAVI but with a different rate curve — often offers better borrow rates on SUI during quieter periods.
Deposit LST collateral into Bucket to mint BUCK, Sui’s native overcollateralised stablecoin. Use BUCK in LP or Scallop while your collateral continues to earn staking rewards. Essentially a Liquity-style CDP for staked SUI.
Provide liquidity on the other two major Sui DEXs — often better routing and incentive APRs on lesser-used pairs. Kriya offers concentrated AMM and perpetuals; Aftermath has smart routing and farm LPs.
Hold an LST for staking yield while shorting SUI perpetuals on BlueFin to remove directional exposure. A delta-neutral way to collect ~4% native APY plus any funding-rate kicker, at the cost of active position management.
Aftermath’s smart order router scans all Sui DEXs and finds the best mint/swap path for LSTs. Use it when entering or exiting LP positions to minimise slippage — meaningful on the bigger sizes where routing alone can add 0.3–0.7% to net yield.
Wallets
Any of these wallets handle native staking and can interact with Sui’s DeFi stack. Sui Wallet is the official reference implementation; the others add richer UX and multi-chain support.
Sui-Specific Risks
Sui’s staking is fairly benign at the base layer; most risk comes from the DeFi layer built on top.
With >80% of supply staked, Sui’s reward schedule distributes a smaller slice per staker. Base APY can drift lower if participation climbs further; the DeFi layer is doing the heavy lifting on total yield.
Each stake object is delegated to exactly one validator. Unlike nomination systems, you can’t spread across several in one action. Diversify by splitting your stake into multiple stake objects across different validators.
Staking changes (start, stop, withdrawal) only take effect at the next epoch boundary. Unstaking isn’t instant — you wait up to 24 hours before the principal is returned.
Sui’s DeFi protocols are 1–3 years old. Fewer battle-tests than Ethereum equivalents. Audits matter; concentrate on protocols with the longest continuous operation and largest TVL.
afSUI / haSUI / vSUI are liquid on Cetus and Kriya but depth is thinner than stETH on Ethereum. Large redemptions can slip; prefer native unstake for size and use LST-DeFi for smaller positions.
Sui does not currently implement slashing, so validator misbehaviour costs you nothing beyond lost rewards for that epoch. That may change; don’t assume zero-slashing is permanent when picking validators.
