Comparison, as of June 11, 2026
kUSD vs USDe on Base.
Ethena's USDe is the largest synthetic dollar in the market, and in June 2026 Coinbase began distributing its yield on Base. Kerne's kUSD is a self-custody synthetic dollar built natively on Base. Both are delta-neutral. The question worth asking is not which yield number is bigger. It is where the backing lives, and how you check it.
The short version.
USDe and kUSD are both delta-neutral synthetic dollars. Each pairs collateral with a short perpetual hedge so the position keeps its dollar value whether crypto rises or falls. They split on one structural axis that actually matters to a holder: where the backing sits and how you verify it.
USDe is backed by staked crypto and short perpetuals held through centralized off-exchange custodians, with Coinbase now acting as Ethena's primary custodian, wallet provider, and perpetuals venue. It is the proven, institutional-scale product, and you trust the custodians' books and attestations.
kUSD is minted one to one from USDC through an on-chain Peg Stability Module on Base. Its backing, the USDC reserve, the vault collateral, and the Hyperliquid hedge, is readable on-chain, and the protocol publishes an hourly cryptographically signed Proof of Reserves. Kerne is small and in its Genesis stage. Its differentiation is not size. It is that you never have to take its word for anything.
What USDe is.
Ethena's USDe is a synthetic dollar backed by a delta-neutral basis position: a long leg of staked ETH and liquid-staked assets, paired with an equivalent short in ETH perpetual futures. The yield-bearing form, sUSDe, earns perpetual funding plus the staking yield on the collateral. USDe is the largest synthetic dollar in the market by a wide margin, and its track record through 2024 and 2025 is a meaningful part of why.
The backing is held through institutional off-exchange settlement providers such as Copper and Ceffu, with hedges executed at centralized venues, and, as of the June 2026 Coinbase partnership, with Coinbase as the primary custodian. Holders keep USDe or sUSDe in their own wallet, but the assets that back the dollar sit with centralized custodians and exchanges. Verification is through the custodians' attestations and Ethena's reserve reporting. This is a legitimate, widely used model. It is a CeFi-custody model.
sUSDe's APY has compressed into the single digits during 2026 as perpetual funding cooled from its 2024 to 2025 highs, when it ran into the double digits. For the current figure, ethena.fi is the canonical source; the live reading below is DefiLlama's independent computation, and /api/apy republishes it under marketContext so the two rates can be compared in one call.
Read just now: DefiLlama computes sUSDe at 4.80% on $1.33 billion staked, from its own pool chart. Kerne also measures the same sUSDe vault on chain hourly, by the identical share-price method it applies to itself, and publishes that figure on the Honesty Index, where it currently reads 4.47% over 30 days. Two independent reads of one vault, both published, allowed to disagree.
What kUSD is.
Kerne's kUSD is a synthetic dollar built natively on Base. The live mint path is the Peg Stability Module: a holder sends USDC and receives kUSD one to one, minus a size-tiered swap fee of 10 basis points that steps down to 5 at $1,000,000 or more per swap, with the mint amount derived from the contract's own USDC balance rather than from any off-chain instruction. The USDC backing the peg is held one to one and is not re-lent. To earn yield, a holder stakes kUSD into skUSD, an ERC-4626 wrapper that accrues the protocol's delta-neutral return: liquid-staked ETH yield plus Hyperliquid perpetual funding, designed for net-zero directional exposure at scale.
The backing is on-chain and self-verifiable. The USDC reserve, the vault collateral, and the hedge are readable on Base, and the protocol publishes an hourly cryptographically signed Proof of Reserves at /api/por/signed, a live reserve breakdown at /api/por, and a live risk surface with every wired threshold at /api/risk-status. The skUSD figure on /api/apy is a model of the deployed book, reading 6.03% as this page was built. It is variable and it is not a guarantee. It is built from liquid-staked ETH yield plus Hyperliquid funding, multiplied by the share of capital actually earning that carry, which is below one because the hedge is sized one for one against spot and the margin behind the short earns nothing, then taken net of strategy costs, an insurance allocation, and the protocol fee. It is the only forward rate Kerne publishes. It is not realized yield, which is published separately and is lower again: 0.00% over the last 30 days.
Kerne is in its Genesis stage and is intentionally small. It does not have Ethena's scale or its years of operating history. What it offers is a different trust model on the same chain.
The difference that matters: where the backing lives.
Strip away the branding and both products do the same financial thing. They hold an asset, short an equal amount of it, and harvest staking yield plus funding. The choice a holder actually makes is about custody and verifiability.
With USDe, the backing assets are custodied by institutional providers and the hedges run on centralized exchanges. You verify the backing by reading the custodians' attestations and Ethena's reporting. The counterparties are CeFi institutions, including, now, Coinbase. For a large set of holders, a regulated custodian and a trusted brand are exactly the right answer.
With kUSD, the USDC reserve is held one to one in an on-chain module, the collateral sits in an on-chain vault, and the hedge, when open, runs on Hyperliquid, an on-chain perpetuals venue. You verify the backing by reading the chain, or by loading a signed JSON the protocol publishes every hour. The smaller, growing set of holders who would rather check the receipts themselves than trust a custodian is who kUSD is built for.
Side by side.

What each is paying, right now.
Fetched when this page was built, not typed. Kerne's figure comes from /api/apy; the peer figures are DefiLlama's own pool charts; the last column is Kerne's hourly on-chain read of the same vault, by the identical method it applies to itself.
| Asset | Rate | Basis | Size | Kerne's own read |
|---|---|---|---|---|
| skUSD (Kerne) | 6.03% | Forward model, deployed basis | Genesis stage, low thousands | 0.00% realized |
| sUSDe (Ethena) | 4.80% | Realized, trailing, per DefiLlama | $1.33 billion | 4.47% |
| sUSDS (Sky) | 3.60% | Realized, trailing, per DefiLlama | $4.66 billion | 3.54% |
| sUSDf (Falcon Finance) | 4.82% | Realized, trailing, per DefiLlama | $65.7 million | 4.99% |
Kerne's modeled figure of 6.03% is currently above every peer figure here (sUSDe at 4.80%, sUSDS at 3.60%, sUSDf at 4.82%). That is not a claim that kUSD pays more: Kerne's number is a forward model and the peer numbers are realized records, measured across billions of dollars rather than a book in the low thousands. Kerne's own realized rate is effectively zero.
NOT LIKE FOR LIKE, AND THE DIFFERENCE FAVOURS KERNE. The Kerne figure on this response is a FORWARD MODEL of the deployed book, computed from a published formula on inputs that move hourly. Every peer figure here is a TRAILING, REALIZED rate DefiLlama computed from that vault's own share price, which is a record of what holders were actually paid. A model and a record are different species of number. Comparing them ranks Kerne on its intention against peers on their performance, so read any Kerne lead as a statement about the model, never about delivery.
THE SIZE GAP IS THE OTHER HALF OF IT. The peer figures are realized across billions of dollars over years. The Kerne model describes a book in the low thousands. A rate is much easier to model on a small book than to sustain on a large one, and nothing here demonstrates that this model survives scale. The tvlUsd on each peer is published beside its rate so the reader can weigh that directly instead of taking our word for the caveat.
KERNE REALIZED IS EFFECTIVELY ZERO AND THAT IS THE NUMBER THAT MATTERS TO A DEPOSITOR. The skUSD vault has received exactly one yield distribution in its life, 0.10 kUSD on 2026-07-09, which the deployment registry records as a plumbing smoke test. Read the `realized` block on this same response, and the Honesty Index, where Kerne is the worst realized row on its own board. A protocol that published the flattering model without the unflattering realization would be doing precisely the thing this codebase exists to oppose.
EVERY FIGURE HERE IS RE-DERIVABLE AND NONE IS STORED. Each peer carries the exact DefiLlama pool chart it was read from, the protocol's own first-party surface, and the Kerne endpoint that measures the same vault on chain hourly by the same ERC-4626 share-price method applied to Kerne itself. Three independent reads per peer, all public, all unauthenticated. The Kerne headline is recomputed on every request to this endpoint from the methodology string above it. Nothing on this response is a cached rate, so a comparison that is favourable today may not be next week, and this endpoint will publish it either way.
Both are legitimate. They are different trust models.
This is not a teardown. Coinbase bringing Ethena's yield to Base is good for the whole category. It puts a delta-neutral synthetic dollar in front of a hundred million people and educates the market at a scale no small protocol could. The pie is getting larger, and Kerne benefits from that education.
When millions of people learn what a synthetic dollar is, they will meet two models. In the custodial model, a regulated institution holds the backing for you, and you rely on its books and its brand. In the on-chain model, you hold the dollar in your own wallet and verify the backing yourself, block by block. Convenience and a trusted custodian will serve a very large audience. A smaller, growing audience would rather hold the asset themselves and check the receipts. Kerne is built for the second group, on the same chain Coinbase just chose.
The risk both share, and how each handles it.
Every delta-neutral synthetic dollar shares one structural risk: when perpetual funding turns negative, the funding leg of the yield goes to zero or below for that period. This is not a flaw unique to either protocol; it is the nature of the trade. Ethena absorbs negative funding from its reserve fund. Kerne runs a dedicated insurance allocation sized against negative-funding episodes, and publishes the live funding regime and a 24-hour forecast at /api/forecast so the condition is visible rather than hidden. The honest read for either product is that the yield is variable and the backing model is the thing to understand before depositing.
Next steps on Kerne.
If a self-custody, on-chain-verifiable synthetic dollar on Base is what you are after, the next step is to hold the dollar you can check for yourself.

USDe's mechanism, custody model, and yield characterization on this page are drawn from Ethena's public documentation at ethena.fi and contemporaneous reporting on the June 2026 Coinbase partnership. For the current sUSDe APY and USDe reserve composition, ethena.fi is the canonical source. Kerne's claims resolve to live endpoints: /api/apy, /api/por/signed, /api/risk-status, and the kUSD contract on Base.
