Best Yield Optimizers on Sui (2026): 9 Vaults Compared

Updated 20 October 2026. TVL figures are from DefiLlama, read on 20 October 2026. Product details come from each protocol's own documentation. Nothing here is financial advice.

Short answer: the best yield optimizer on Sui depends on the strategy you want. For curated stablecoin yield, the largest option is Ember (about $34.9M on Sui). For passive lending yield routed across Sui money markets, look at the Haedal Lending Vault. For the widest range of strategies in one app, JewelSwap runs auto-compounding Cetus and Turbos farms, leveraged Scallop farms boosted by veSCA, and two looping vaults, Ember Loop and NAVI Loop, and the same app covers MultiversX and Radix. For leveraged LP farming, Kai Finance and Mole are the specialists. For classic auto-compounding vaults, AlphaFi is the one DefiLlama files as a Sui yield aggregator.

Sui has plenty of places to earn yield and fewer that manage that yield for you. A yield optimizer is the second kind: you deposit once, and a contract or a curator harvests rewards, reinvests them, rebalances or manages leverage on your behalf. This guide compares the Sui protocols that actually do that job in 2026, explains how they differ, and gives a short checklist to run before you deposit.

TVL is a size signal, not a quality score. A large vault is not automatically safer, and a small one is not automatically riskier. Use the table to shortlist, then read the risk section below.

What counts as a yield optimizer on Sui?

"Yield optimizer", "yield aggregator" and "vault" are used loosely. On Sui, the products fall into four groups:

• Auto-compounders. They harvest farming rewards on a schedule, swap them back into the position and reinvest. This is the classic yield aggregator model. AlphaFi, Nemo and JewelSwap's Cetus and Turbos farms work this way. See how auto-compounding works.
• Curated vaults. A curator decides where deposits go and adjusts the mix over time. Ember and Volo vaults are in this group. Our guide to vault curators explains who makes the decisions and how to judge them.
• Leveraged farms. They borrow against your deposit to make the position bigger, which raises both yield and liquidation risk. Kai Finance, Mole and JewelSwap's Scallop farms are here. Start with leverage in crypto if this is new.
• Looping vaults. They supply an asset, borrow against it and resupply in one transaction, so the vault earns a spread on several times your deposit. JewelSwap's Ember Loop and NAVI Loop and Suilend's own Strategies product belong here. See DeFi looping explained.

The word "best" therefore only makes sense once you have chosen a group. A curated stablecoin vault and an 11x LP farm are not competing for the same deposit.

How we compared Sui yield optimizers

We included protocols that run on Sui and manage a position for you after deposit. Lending markets you manage yourself, such as Scallop, NAVI and Suilend, are covered in our Sui lending comparison instead. For each optimizer we checked:

• Strategy: what the vault does with your money, from the protocol's own docs.
• Leverage: whether the position borrows, and how much.
• Size: TVL on Sui from DefiLlama on 20 October 2026.
• Transparency: whether fees, audits and exit mechanics are documented.

We do not quote APYs. Sui vault yields move week to week with reward programmes and borrow rates, so a number printed here would be stale soon. Check the live figure in each app and compare it with the APY and APR definitions it uses.

Curated vaults: Ember, Haedal, Volo and Aftermath

Ember

Ember is the largest vault platform on Sui by TVL, with about $34.9M on Sui and $104.4M across all chains on DefiLlama. Curators run strategies behind each vault, and your return shows up as a rising vault token price; its USDC vault token is eEARN. The trade-off is that the strategy is set by the curator, so you are trusting their risk choices and the platform's controls. Our Ember Protocol guide covers how curators and rate updates work.

Haedal Lending Vault

Haedal is best known for its haSUI liquid staking token, covered in what is Haedal. Its Lending Vault (about $6.4M) puts deposits into other Sui lending protocols on your behalf, so you get lending yield without choosing the market yourself. Haedal also lists a separate automated farming vault at about $0.9M.

Volo vaults

Volo started as the issuer of vSUI (see what is Volo) and now runs curated vaults with about $2.8M on DefiLlama, including BTCFi-focused ones. It suits holders who already use vSUI.

Aftermath afLP

Aftermath's afLP is a USDC vault (about $5.5M) that acts as the community market maker for Aftermath's perpetuals. Depositors share trading fees, liquidation income and trader PnL, which means the vault can lose money when traders win. It is a different risk from lending yield. Our Aftermath Finance guide explains the rest of the protocol.

JewelSwap: auto-compounding, leveraged and looping vaults on Sui

JewelSwap is a multi-chain DeFi protocol on Sui, MultiversX and Radix. On Sui it offers four kinds of managed yield, all documented in the JewelSwap docs:

• Cetus auto-compounding farms. JewelSwap provides the liquidity, harvests rewards from Cetus every 30 minutes, swaps them back into the pair and re-adds liquidity. Pairs listed in the docs include USDC–SUI, USDC–ETH, CETUS–SUI and DEEP–SUI.
• Turbos auto-compounding farms. The same 1x model on Turbos, with USDT–USDC, SUI–USDC and NS–SUI farms. There is no borrowing and no liquidation risk. A 15% performance fee is taken from harvested rewards, and the other 85% is reinvested.
• Scallop leveraged farms. You deposit collateral, the farm borrows against it at a 65% collateral weight (about 2.86x) and supplies the borrowed coin back into Scallop. Rewards are boosted by JewelSwap's veSCA position, up to 4x on incentive rewards. Farms include suiUSDT–USDC and a BTC-against-BTC pair. Our Scallop farm guide walks through the mechanics.
• Looping vaults (Labs, beta). Ember Loop holds about 4.5x your USDC in Ember's eEARN, using Suilend as the lender. NAVI Loop supplies and borrows the same stablecoin (USDY or USDSUI) on NAVI at about 2.6–3x. Both are public, unaudited betas. Our Ember Loop vs NAVI Loop comparison sets out their fees and exits.

Why it stands out: range. You get auto-compounding, leveraged and looping strategies in one interface, and the same app covers MultiversX and Radix. The looping vaults are unaudited betas, so size positions accordingly, and check in the app which farms are open to new deposits before you plan a position. For the wider product set, see JewelSwap on Sui.

Auto-compounding aggregators: AlphaFi and Nemo

AlphaFi is the protocol DefiLlama classifies as a Sui yield aggregator and describes as a yield optimizer. Its vaults auto-compound DEX and lending positions. Its aggregator TVL was about $2.2M on 20 October 2026, down from $3.4M on 5 October, so confirm which vaults are still open before depositing. Nemo runs smaller rebalancing and auto-compounding vaults (about $31k on DefiLlama).

Leveraged yield: Kai Finance and Mole

Kai Finance splits users into two sides. Passive depositors put single assets into vaults and earn interest from borrowers. Active users borrow that liquidity to farm LP pairs on Sui DEXs with up to 11x leverage, according to Kai's docs. Kai says its contracts are open source and audited; DefiLlama lists no audit links, so read the reports yourself.

Mole combines savings pools, leveraged yield farms on Sui DEXs such as Cetus, and managed funds. Lenders earn the interest leveraged farmers pay. Borrow rates rise with pool utilisation, which matters if you farm with leverage during busy markets.

High leverage multiplies impermanent loss as well as rewards. A 10x LP position on a volatile pair can be liquidated by a move that a 1x position would barely notice.

Also worth knowing

• Suilend Strategies runs its own one-click eEARN/USDC loop of up to 4.5x, a direct alternative to Ember Loop. See how to use Suilend.
• NAVI Prime added curator-led isolated lending vaults to NAVI in August 2026. Compare it with the other markets in NAVI vs Suilend.
• Liquid staking is the simplest managed yield on Sui: you hold an LST and staking rewards accrue to it. Our Sui liquid staking comparison covers haSUI, vSUI, afSUI and JWLSUI.

Risks to check before you deposit

• Smart contract risk stacks. An optimizer sits on top of a DEX or lending market, so a bug in either layer can hit you. Read how to check a DeFi protocol is safe.
• Audits. Look for named audit reports for the vault contracts themselves, not only for the underlying protocol. Beta vaults may have none.
• Leverage and liquidation. A borrowed position can be liquidated if prices or rates move against it. Read how DeFi liquidations work.
• Reward dependence. Many Sui yields come from incentive programmes. When emissions fall, so does the APY, and a leveraged position can turn negative if the borrow rate rises above what it earns.
• Exit terms. Check withdrawal queues, fees and how much liquidity backs an exit before you deposit.
• Curator and admin powers. Find out who can change strategy, fees or limits, and whether there is a timelock or a multisig.

Frequently asked questions

What is the best yield optimizer on Sui?

It depends on the strategy. Ember is the largest curated vault platform on Sui (about $34.9M TVL on 20 October 2026). Haedal's Lending Vault suits passive lending yield. JewelSwap covers the most strategies in one app: auto-compounding Cetus and Turbos farms, leveraged Scallop farms and looping vaults. Kai Finance and Mole specialise in leveraged LP farming, and AlphaFi runs auto-compounding vaults.

What is the difference between a yield optimizer and a yield aggregator?

The terms overlap. A yield aggregator usually means an auto-compounder that harvests and reinvests rewards. "Yield optimizer" is broader and also covers curated vaults, leveraged farms and looping vaults that manage a position for you.

Is JewelSwap a yield optimizer on Sui?

Yes. JewelSwap auto-compounds Cetus and Turbos liquidity positions every 30 minutes, runs leveraged Scallop farms at about 2.86x with a veSCA reward boost, and offers the Ember Loop and NAVI Loop looping vaults as unaudited betas. It also operates on MultiversX and Radix.

How often do Sui yield optimizers compound?

It varies by protocol. JewelSwap's Cetus and Turbos farms harvest and reinvest every 30 minutes. Curated vaults such as Ember accrue yield in the vault token's price instead of compounding on a fixed schedule.

Which Sui yield optimizer is the safest?

No vault is risk-free. Lower-risk choices are usually unleveraged, audited, stablecoin strategies with clear exit terms. Leveraged farms, looping vaults and beta products carry more risk because they can be liquidated or have less battle-tested code.

Do I need to manage anything after depositing?

Usually not. The optimizer harvests, reinvests and manages leverage for you. You should still watch reward programmes, borrow rates and any announcements, because those decide whether the strategy keeps paying.
