K3 Capital

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

REJECTED ON TOTAL ENTITY OPACITY. K3 Capital curates vaults on Euler v2 and Morpho and runs a proprietary Liquity v2 Stability Pool wrapper, sBOLD, holding roughly $393M across nine chains. No legal entity name, incorporation jurisdiction, or team or founder identity appears anywhere in K3’s own materials, and no independent journalism or third-party coverage of K3 as a company was found in any source this review could access — a curator holding hundreds of millions of dollars with zero disclosed operator identity is itself a disqualifying fact for institutional coverage. K3’s own marketing site actively geo-blocks US visitors, redirecting to a notice that ”no services are being offered to US residents.” Tracked TVL fell roughly 53%, from about $406M in November 2025 to about $190M in May 2026, before recovering to its current level, with no cause identifiable from DefiLlama’s hacks database, rekt.news, or Euler’s own governance forum — an unexplained, material swing this review could not resolve. Separately, a meaningful share of K3’s Monad TVL traces to vaults Euler DAO itself sunset and handed to K3 as a ”qualified curator” in April 2026, with no documented vetting rationale published in that governance decision.

Kill criteria: the events that revoke this verdict
• A named legal entity, incorporation jurisdiction, and team identity are publicly disclosed
• The cause of the November 2025 to May 2026 TVL decline is identified and confirmed
• A documented, independent vetting rationale for K3’s qualified-curator status is published, whether by Euler DAO retroactively or another governance body
• On-chain KYC or allow-list enforcement, or its confirmed absence, is verified directly against the vault contracts rather than inferred from the marketing site

The research file

Mechanism

K3 runs ERC-4626 vaults on Euler v2 (confirmed live products: ”K3 Capital Earn WETH” and ”K3 Capital Earn AUSD” on Monad, ”K3 Capital USDT0 Vault” on Plasma) and on Morpho, plus a proprietary product, sBOLD, which splits deposits across wstETH, wETH, and rETH Liquity v2 Stability Pools at a stated 60/30/10 weighting K3 rebalances biweekly at its own discretion. sBOLD carries product-level audits from ChainSecurity and Dedaub. K3’s own documentation discloses that sBOLD can halt deposits and withdrawals when unrealized post-liquidation collateral exceeds a set ceiling, and that rounding is explicitly biased against the depositor to protect vault solvency — disclosed, but a real liquidity-gating mechanism, not pure on-demand redemption.

No disclosed legal entity or team

K3’s marketing site footer reads only ”© K3 Capital,” with dead Privacy Policy and Terms of Service links. No entity name, jurisdiction, founder, or team member identity was found anywhere in K3’s own materials, and no independent coverage — press, research writeups, or third-party analysis — of K3 as a company exists in any source this review could reach. Every path on k3.capital, including the sitemap, redirects US-origin requests to a placeholder stating no services are offered to US residents — the one confirmed access restriction, though whether the underlying vault contracts themselves enforce any on-chain allow-list beyond that marketing-site geo-block is unverified.

The Euler DAO handover

On 2026-04-10, Euler DAO’s governance forum posted a proposal to sunset its own DAO-managed markets and vaults across eight chains, citing that market operations sat outside Euler’s core competency and that risk providers running competing vaults elsewhere created conflicts of interest. K3, alongside AlphaGrowth, was named a ”qualified curator” and inherited roughly 15 previously DAO-run vaults, including several Monad Earn vaults. The governance thread contains no documented vetting rationale or prior K3 track record cited as the basis for that qualification — a real gap in the one public decision that formally endorsed K3 as a curator.

The unexplained TVL swing

DefiLlama-tracked TVL fell from roughly $406M in November 2025 to roughly $190M by May 2026, a decline of about 53%, before recovering to the current roughly $393M. No exploit, bad debt event, or depeg tied to K3 was found in DefiLlama’s hacks database, a direct rekt.news search, or the Euler governance forum, and the Euler sunset event postdates most of the decline and covers only a small vault subset — it does not explain the bulk of the swing. Part of the apparent movement may reflect vault addresses being added to or removed from DefiLlama’s tracking configuration rather than real capital flows, but this could not be confirmed either way, so this review records the swing as an open, unexplained data point rather than assert a cause.

Comparison and decision

By current TVL, K3 sits between smaller and larger established curators like Re7 Labs and Gauntlet, but unlike either of those firms, which publish research output and (in Gauntlet’s case) carry disclosed institutional backing, K3 discloses no team, entity, or jurisdiction at all. That combination — meaningful size, total operator opacity, and an unvetted DAO handover in its recent history — is disqualifying for this registry regardless of the underlying vault mechanics’ technical soundness.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
