Passive yield sounds simple until impermanent loss shows up in your LP position. Many liquidity providers collect steady trading fees for months, only to find their position is worth less than if they had just held their tokens. For users who want yield without managing a token pair, single-asset vaults offer a cleaner path.
ether.fi Liquid vaults are one of the most established options in this category, with more than $450 million in TVL across the vault suite at the time of writing. Since September 25, 2026, Liquid ETH, Liquid USD and Liquid BTC have been available on KyberEarn, the earning hub of KyberSwap. This guide explains how impermanent loss works, how the main passive yield options compare and why ether.fi vaults on KyberEarn are a strong fit for hands-off earners.
What Is Impermanent Loss and Why Does It Hurt Passive Yield?
Impermanent loss (IL) is the gap between the value of your LP position and the value of simply holding the same tokens. It happens when the prices of the two tokens in a pool move apart. As traders swap against the pool, your position is rebalanced, so you end up holding more of the token that fell and less of the token that rose.
The numbers add up fast. In a standard 50/50 pool, a 2x price move between the two tokens creates roughly 5.7% IL. A 5x move creates about 25.5%. Concentrated liquidity pools can magnify this effect, because your capital sits in a narrower price range.
This is where passive LPs get hurt. Trading fees are meant to compensate for IL, but they don’t always keep up. When IL grows faster than the fees you collect, it can eat all your earnings and push your position into negative profit. You can earn fees every single day and still finish with less than you would have by holding.
What Are the Main Ways to Earn Passive Yield in DeFi?
Most passive yield in DeFi comes from four sources. Each one offers a different mix of effort, risk and IL exposure.
- Liquidity provision (LPing): You deposit a token pair into an AMM pool and earn trading fees plus any incentives. Returns can be attractive, but you carry direct IL exposure and may need to manage price ranges.
- Lending: You supply a single asset to a lending market and earn interest from borrowers. There is no IL, but rates move with demand and withdrawals depend on available pool liquidity.
- Liquid staking: You stake ETH and receive a liquid token such as weETH that earns staking rewards. It is simple and IL-free, but your yield depends on a single source.
- Automated yield vaults: You deposit a single asset, and a strategy allocates it across multiple DeFi protocols. The vault handles rebalancing and compounding for you.
Vaults sit in a useful middle ground. You keep single-asset exposure like lending or staking, but your capital can reach several yield sources at once. There are no ranges to set and no positions to rebalance by hand.
How Do ether.fi Liquid Vaults Work?
ether.fi Liquid vaults are automated DeFi strategies built for hands-off earning. You deposit a supported asset, and the vault spreads it across a diversified set of DeFi positions. As market conditions change, the strategy rebalances and compounds rewards automatically.
Three vaults are available on KyberEarn, all running on Ethereum:
- Liquid ETH allocates capital across ETH-focused DeFi strategies. Its base deposit assets include eETH, weETH and WETH.
- Liquid USD targets market-neutral stablecoin strategies. It suits users who want dollar-denominated yield.
- Liquid BTC focuses on a diversified set of Bitcoin yield opportunities.
Rewards are not paid out separately. Instead, they continuously grow your vault balance, so compounding happens without any claims. ether.fi also keeps a small share of vault funds liquid to support withdrawals.
Safety checks are part of the design. Vaults such as Liquid USD are built on the Veda architecture, where every rebalance must pass a Merkle proof check. This proves each strategy move stays within predefined constraints.
Why Use ether.fi Vaults Through KyberEarn?
KyberEarn hosts ether.fi’s vaults in a new section called Partner Vaults. This section lists yield strategies managed by external protocols, and ether.fi Liquid is its first integration. For users, the main benefit is simpler access at no extra platform cost.
- Deposit with the tokens you already hold. Use up to 5 tokens from your wallet, even if they don’t match the vault’s base token. KyberSwap handles the conversion during the deposit, so you skip the separate swap.
- Pay no KyberSwap platform fee on vault deposits. More of your capital goes to work from day one.
- Keep your ether.fi rewards. Depositors still earn ether.fi points and partner rewards when entering through KyberEarn.
- Track everything in one place. Monitor your vault positions from My Vaults, right next to the rest of your KyberEarn activity.
- Choose how you exit. An instant withdrawal converts your position into another token through market liquidity. A native withdrawal usually takes around 3 days and can take up to 10 days, depending on strategy conditions.
KyberSwap is best known for its KyberSwap Aggregator, which connects to 650+ liquidity sources across 20 chains. With Partner Vaults, the platform brings the same aggregation idea to earning. You get access to professionally managed strategies without leaving the DeFi trading platform you already use for swaps.
How Do the Options Compare?
| Option | IL exposure | Effort | Main yield source | How you exit |
|---|---|---|---|---|
| LPing on AMMs | Direct IL | High (ranges, rebalancing) | Trading fees and incentives | Withdraw anytime in the pool’s token ratio |
| Lending | None | Low | Borrower interest | Anytime, if pool liquidity allows |
| Liquid staking (e.g. weETH) | None | Low | Ethereum staking rewards | Sell on market or join the unstaking queue |
| ether.fi Liquid vaults on KyberEarn | No direct IL (no LP pair to manage) | Low | Automated, diversified DeFi strategies | Instant via market liquidity or native (about 3 days, up to 10) |
What Risks Should You Know Before Depositing?
No yield product is risk-free, and vaults are no exception. Removing the LP pair takes away direct IL, but other risks remain.
- Variable APY: Estimated APY is informative, not guaranteed. Returns change with market conditions.
- Strategy exposure: Vault strategies may use positions such as concentrated liquidity under the hood. The vault manages that exposure for you, but it doesn’t remove every market risk.
- Smart contract and third-party risk: Your funds interact with vault contracts and the external protocols the strategies use.
- Price impact and slippage: Depositing with non-base tokens requires a conversion, which can affect the final amount you deposit.
- Withdrawal timing: Native withdrawals can take up to 10 days. Instant exits depend on available market liquidity.
Always review the quoted amounts and details in the interface before you confirm a deposit or withdrawal.
What If You Still Want to Provide Liquidity?
Some users still prefer LPing for its fee potential. KyberEarn also helps here. Its Low Volatility category highlights stablecoin and correlated-asset pools where IL risk is minimal. For more volatile pairs, Smart Exit lets you set conditions such as a target price or time, and your position is withdrawn automatically when they are met. This helps limit further IL without watching the market all day.
How Do You Start Earning Passive Yield on KyberEarn?
Getting started takes only a few minutes. Head to the Partner Vaults section on KyberEarn and pick the vault that matches the asset you want exposure to: ETH, stablecoins or BTC. Deposit with any mix of up to 5 tokens you already hold, and let the vault handle allocation, rebalancing and compounding from there.
Your ether.fi points keep accruing, KyberSwap adds no platform fee to your deposit, and you can track every position from My Vaults.
FAQ
Do ether.fi Liquid vaults have impermanent loss?
You don’t hold a two-token LP position, so there is no direct IL for you to manage. Your exposure stays with the vault’s asset category, such as ETH, stablecoins or BTC. The underlying strategies may still use LP positions, and those are managed by the vault as part of its strategy.
Can LPing lead to negative returns even with trading fees?
Yes. If the prices of the two tokens in a pool move far apart, IL can grow faster than the fees you earn. In that case, IL can wipe out all your fee income and leave you with less value than simply holding the tokens.
Which tokens can I use to deposit into ether.fi vaults on KyberEarn?
You can deposit with up to 5 tokens from your wallet in one go. The tokens don’t need to match the vault’s base asset, because KyberSwap converts them during the deposit. Keep in mind that converting non-base tokens can involve some price impact and slippage.
Does KyberSwap charge a fee on vault deposits?
No. KyberSwap charges no platform fee on deposits into ether.fi vaults. Standard network gas still applies to your transaction.
Will I still earn ether.fi points if I deposit through KyberEarn?
Yes. Depositors keep earning ether.fi points and partner rewards when they enter the vaults through KyberEarn.
How long do withdrawals take?
You have two options. An instant withdrawal converts your position into another token through market liquidity. A native withdrawal usually takes around 3 days and can take up to 10 days, depending on strategy conditions.
How much can I earn with ether.fi Liquid vaults?
Yields are variable and depend on each vault’s strategies and market conditions. Check the current estimated APY for each vault on KyberEarn before depositing, and remember that estimates are not guaranteed.
