Scorecard, as of June 18, 2026
Every synthetic dollar that blew up this cycle blew up in the same place.
Somewhere you could not see. Not the mechanism, the trust model. This page names what actually failed, with sourced and dated facts, and shows where Kerne kUSD sits on each axis, against a live proof you can check yourself.
The short version.
Strip the branding off the collapses of the last two years and they rhyme. The delta-neutral idea, hold an asset and short an equal amount of it, harvest funding and staking yield, kept working the whole time. What broke was always the same thing: backing you could not see, held somewhere you could not check, controlled by a key, a manager, or a verifier you simply had to trust.
Kerne is the opposite by design. kUSD mints 1:1 from USDC through an on-chain Peg Stability Module on Base. The collateral and the Hyperliquid hedge are reported in a signed Proof of Reserves every hour. Nothing that backs the dollar sits in a place you cannot read for yourself. Kerne is small, pre-audit, and in its Genesis stage, and it says so on this page. Its edge is not size or yield. It is that you never have to take its word for anything.
What actually failed.
Four events, each sourced and dated below. Read the middle column. In every case the loss lived somewhere off-chain, behind a single point of control the holder could not inspect.
| Protocol | When | What you could not verify | What it cost |
|---|---|---|---|
| Stream FinancexUSD | Nov 2025 | Backing held off-chain by an external manager with no public multisig or custody. The issuer disclosed an estimated $93M loss tied to that manager. | xUSD fell ~77%. Looping amplified it into ~$285M of exposure across lenders. |
| ResolvUSR | Mar 2026 | A single compromised off-chain signing key was the sole gate on minting. It minted ~80M unbacked USR from a ~$100k deposit. | ~$24.5M extracted before the team paused the contracts. USR fell from $1 to ~$0.025 before partial recovery. |
| ElixirdeUSD | Nov 2025 | ~65% of reserves (~$68M USDC) were lent to Stream, off-chain. When Stream defaulted, the backing was not there. | deUSD fell ~98% to ~$0.015. The protocol wound down. |
| Kelp DAO / KernelDAOrsETH (bridge) | Apr 2026 | A forged cross-chain message passed a single 1-of-1 off-chain bridge verifier. A different project from Kerne; a bridge failure, not a stablecoin collapse. | ~$292M drained (~18% of supply). Lenders froze rsETH markets within hours. |
Figures are widely reported headline estimates; sources are listed at the bottom of this page. The Kelp DAO event was a cross-chain bridge exploit on a restaking token, not a synthetic-dollar collapse, and KernelDAO is a different project from Kerne (see /not-kerneldao). It is included because it is the same root cause: a single off-chain point of control.
The pattern, said once.
None of these were failures of the delta-neutral trade. Funding did not blow up the positions. A market move did not break the hedge. In each case a human or a machine that the holder could not audit was the single point of failure: a fund manager moving money off-chain, a backend key signing an unbounded mint, a treasury lending the reserves to someone else, a lone bridge verifier waved through a forged message.
That is the axis a serious allocator chooses on. Not the headline APY. The question is how much of the system you are required to take on faith, and how much you can check before you deposit and at any moment after.
The scorecard.
The left column is the failure pattern the cohort shared. The right column is Kerne's posture on the same axis, each one linking to a proof you can open right now. The point is not that Kerne is immune. It is that every claim is checkable.
| Axis | The failure pattern | Kerne kUSD, verifiable |
|---|---|---|
| Where the backing lives | Off-chain, with a manager or custodian whose books you cannot read. | On-chain. USDC held 1:1 in the PSM, vault collateral, and the Hyperliquid hedge, all readable on Base. /transparency |
| Who can mint supply | A single off-chain key or signer, often with no per-call cap. | MINTER_ROLE held only by on-chain contracts. The PSM derives the mint amount from its own USDC balance; no off-chain key, no caller-supplied number. Admin is a 2-of-3 Safe. verify in 3 commands |
| Reserve verifiability | Periodic attestations, or a dashboard you take on faith. | An hourly, cryptographically signed Proof of Reserves anyone can re-derive against the chain. /api/por/signed |
| Oracle and depeg disclosure | Quietly assumes pegs hold; the limit surfaces only in the exploit write-up. | States plainly that the PSM values USDC at 1:1 by design and does not independently price a USDC depeg. /security |
| Leverage disclosure | Headline yield, no statement of the notional exposure behind it. | Publishes that skUSD yield is built from staking plus funding under dynamic leverage, net of costs, and is variable. /api/apy |
| Getting your money out | Redemption can queue, gate, or pause at the moment you need it. | kUSD redeems 1:1 for USDC on-chain, with no queue and no permission, by design. /docs |
Where Ethena fits, honestly.
Ethena does not belong in the list above. USDe is the largest synthetic dollar in the market and the most proven one, and nothing here is a knock on it. It is the surviving incumbent, not a casualty. Its backing is held with regulated, institutional custodians, and as of June 2026 Coinbase is its primary custodian and is distributing its yield on Base. You verify it through custodian attestations and reserve reporting.
That is a legitimate model, and for a very large audience it is the right one. The difference is the trust assumption, not the safety. sUSDe's yield has compressed into the single digits in 2026 as funding cooled, which is part of why holders are spreading across more than one name. If you are weighing the custodial giant against a self-custody option on the same chain, the full structural comparison is at /kusd-vs-usde.
What Kerne still owes.
A transparency page that hid its own weak spots would be the very thing it warns against. So here they are, plainly.
- Pre-audit. Kerne has not completed an external audit. An internal adversarial review and its findings are public at /security/findings-tracker, and an independent engagement is being finalized. Until that lands, the smart-contract risk is real and undiluted.
- Genesis scale, modelled yield. Kerne is intentionally small. The skUSD engine does not yet have a base of third-party stakers, so the published APY is a live, methodology-backed model rather than a large realized distribution. It is computed at /api/apy and the live size is at /api/stats. Both are honest numbers; neither is a big one.
- The insurance fund is not yet capitalized. Kerne's design routes a share of yield into a dynamic insurance fund that absorbs negative-funding stretches, but at Genesis scale that fund holds essentially nothing today. Until it builds up as the book grows, an adverse funding regime is borne by the strategy directly, with no buffer in front of it. The allocation mechanism is live; the balance is honestly near zero, readable in the Proof of Reserves.
- The off-chain leg is self-reported. The on-chain reserves are independently readable by anyone. The Hyperliquid hedge equity in the Proof of Reserves is reported by Kerne and bound to a signature; an independent third-party attestation of that leg is being scoped.
- The USDC-depeg blind spot. The PSM values USDC at 1:1 by design, so on its own it does not independently price a USDC depeg. We would rather you know that here than find it in an exploit write-up later.
- A degraded legacy vault. The original v1 WETH vault is in a known degraded accounting state. It is ringfenced via an on-chain flag and excluded from reported TVL, surfaced live as vaultDegraded on /api/stats; the v2 redeploy is on the punch list.
None of this is hidden, and that is the entire argument. A protocol that tells you its weak spots before you ask is making a different bet than one whose weak spots you discover after the fact.
Don't trust this page. Check it.
Everything above resolves to something you can open without our permission. These are the four surfaces worth your time, each a live link rather than a marketing claim.
- /api/por/signed: the hourly signed Proof of Reserves, with on-chain assets, hedge equity, solvency ratio, and a signature you can check against the published signer.
- /api/risk-status: every wired risk threshold with its current on-chain value and source-file attribution.
- /transparency and /tear-sheet: the live backing, the source-verified contracts, and the one-page factsheet.
- /resolv-vs-kerne: the three on-chain commands that check the mint path, the exact class of failure that drained Resolv.
Next steps on Kerne.
If a synthetic dollar you can verify yourself on Base is what you are after, the next step is to hold the dollar you can check.
