Hyperithm

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

REJECTED ON CONCENTRATION AND A LICENSING MISMATCH, NOT ON FIRM CREDIBILITY. Hyperithm Co., Ltd. is a real, disclosed Tokyo-registered proprietary trading firm founded in 2018 with genuine institutional investors (Coinbase Ventures, Samsung Next, Hashed) and trade-press visibility. But its Japanese regulatory registration is a Qualified Institutional Investor exemption — a light-touch registration for funds sold only to other institutions — not a full discretionary asset-management license, and that registration covers Hyperithm’s CeFi fund products, not the on-chain vaults this registry is asked to evaluate. Those on-chain vaults span four separate, structurally different venues (Morpho, Accountable Capital, Midas, Neutral), and despite marketing describing coverage across ten chains, roughly 70% of tracked TVL concentrates in a single Accountable Capital vault on Monad — a concentration this registry treats as a real risk the ”ten-chain” framing obscures. No Hyperithm-specific vault audit was found, and redemption mechanics for the largest vaults could not be confirmed beyond a general ”Open Term, subject to strategy liquidity” label.

Kill criteria: the events that revoke this verdict
• A single, consistent eligibility and legal-claim disclosure exists across all four venues Hyperithm curates on, or this entry is split by venue
• TVL concentration diversifies meaningfully beyond the current single Monad vault
• A curator-specific, Hyperithm-attributed audit is published for the vaults holding the bulk of tracked capital
• A regulatory registration covering the on-chain vault business specifically, not only the CeFi fund business, is disclosed

The research file

Mechanism and venue fragmentation

Hyperithm curates vaults across four separate infrastructure providers rather than a single rail: 15 small Morpho vaults across five chains (combined roughly $3M); two Accountable Capital vaults, a $100M-capped, fully-filled USDC delta-neutral vault and a partially-filled cbBTC delta-neutral vault; a tokenized fund token on Midas, mHYPER, whose terms and AUM this review could not independently verify; and a systematic US-equities strategy on Neutral, a Solana-only vault marketplace. What a depositor actually holds — an ERC-4626 share, an Accountable lending-exposure share, a Midas fund token, or a Neutral vault share — differs by venue and carries a different legal and technical claim in each case, meaning ”Hyperithm” as a single line item obscures materially different underlying risks.

The licensing gap

Hyperithm Co., Ltd., Tokyo, established 2026-01-29 [sic — 2018-01-29], discloses its field of business as proprietary trading and a Qualified Institutional Investor Fund registration under Japan’s FIEA framework — an exemption for funds sold only to qualified institutional investors, not a full asset-management license. A Seoul entity marketed alongside the Tokyo headquarters is disclosed as a subsidiary, not a co-equal headquarters, which somewhat overstates the Korean entity’s standing relative to how it is marketed. No on-chain-vault-specific regulatory registration was found — the QII exemption applies to Hyperithm’s CeFi fund business, not to the permissionless vaults this memo covers.

Concentration the chain count obscures

Current chain-by-chain TVL: Monad roughly $181M (about 70% of the total), Ethereum roughly $77M, with the remaining eight chains combined under $1M and several at zero. The Monad concentration traces almost entirely to the single, fully-subscribed $100M Accountable Capital USDC delta-neutral vault. A client evaluating ”Hyperithm” as a ten-chain, diversified curator would be missing that the overwhelming majority of exposure sits in one vault on one chain.

Eligibility and comparison to K3 on the same platform

Hyperithm’s vaults on Accountable Capital and Neutral are both explicitly labeled permissionless, open to any wallet from a $100 minimum on Neutral. This stands in direct, sourced contrast to K3 Capital’s vault on the identical Accountable Capital marketplace, researched separately in this batch, which is whitelist-gated — the same platform hosts both an open and a gated curator side by side, useful evidence that eligibility is a per-curator choice on Accountable, not a platform-wide policy. No multisig signer identities, admin-key structure, or custodian relationship specific to Hyperithm’s own curator role were disclosed on any of the four venues it operates on.

Track record, audits, and decision

DefiLlama has tracked Hyperithm’s protocol page since 2025-05-20 and records zero audits credited specifically to Hyperithm as curator — underlying rails like Morpho carry their own separate audits, but no Hyperithm-specific vault audit was located. Self-reported performance figures (a claimed 3.7 Sharpe ratio since 2018, over 92% positive weeks in the trailing 12 months) are unaudited and self-published. No specific incident of curator misjudgment or loss was found, but this review’s search coverage of independent sources was limited by tooling constraints, so it should be read as an absence of findings rather than a confirmed clean record. Combined with the licensing mismatch and concentration finding above, this registry cannot recommend an allocation to ”Hyperithm” as a single line item today.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

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.
