Hyperithm

This review rejects Hyperithm because of concentration and a licensing mismatch, not doubts about the firm’s 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. That registration covers Hyperithm’s CeFi fund products, not the on-chain vaults this registry is reviewing. Those on-chain vaults span four separate venues with different structures (Morpho, Accountable Capital, Midas, Neutral). Despite marketing that describes coverage across ten chains, roughly 70% of tracked TVL sits in a single Accountable Capital vault on Monad. This registry views that concentration as a real risk hidden by the “ten-chain” framing. No Hyperithm-specific vault audit was found, and this review could not confirm redemption mechanics for the largest vaults beyond a general “Open Term, subject to strategy liquidity” label.

Review triggers: events that reopen the 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

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-19.

The research file

Mechanism and venue fragmentation

Hyperithm curates vaults across four separate infrastructure providers rather than one system: 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. The asset a depositor holds differs by venue: an ERC-4626 share, an Accountable lending-exposure share, a Midas fund token, or a Neutral vault share. Each carries a different legal and technical claim, so listing “Hyperithm” as one line item hides material differences in the underlying risks.

The licensing gap

Hyperithm Co., Ltd., Tokyo, established 2026-01-29 [sic: 2018-01-29], lists its business as proprietary trading and holds a Qualified Institutional Investor Fund registration under Japan’s FIEA framework. This exemption applies to funds sold only to qualified institutional investors and is not a full asset-management license. Hyperithm markets a Seoul entity alongside its Tokyo headquarters but discloses it as a subsidiary, not a co-equal headquarters. That marketing somewhat overstates the Korean entity’s standing. No regulatory registration specific to on-chain vaults was found. The QII exemption covers Hyperithm’s CeFi fund business, not the permissionless vaults in this memo.

Concentration the chain count obscures

Current chain-by-chain TVL is as follows: Monad roughly $181M (about 70% of the total), Ethereum roughly $77M, and the remaining eight chains combined under $1M, with several at zero. Almost all of the Monad concentration comes from the single, fully-subscribed $100M Accountable Capital USDC delta-neutral vault. A client who sees “Hyperithm” as a ten-chain, diversified curator could miss that the overwhelming majority of exposure sits in one vault on one chain.

Eligibility and comparison to K3 on the same platform

Accountable Capital and Neutral both explicitly label Hyperithm’s vaults permissionless. Any wallet can use them, with a $100 minimum on Neutral. This directly contrasts with K3 Capital’s vault on the same Accountable Capital marketplace, researched separately in this batch, which requires a whitelist. The same platform hosts an open curator and a gated curator side by side. This shows that each curator sets eligibility on Accountable; the platform does not impose one policy. None of the four venues where Hyperithm operates disclosed multisig signer identities, the admin-key structure, or a custodian relationship specific to Hyperithm’s curator role.

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 systems such as Morpho have separate audits, but no Hyperithm-specific vault audit was found. Hyperithm self-reports a claimed 3.7 Sharpe ratio since 2018 and over 92% positive weeks in the trailing 12 months. These figures are unaudited and self-published. No specific incident of curator misjudgment or loss was found. But tooling constraints limited this review’s search of independent sources, so this means no finding was made, not that the record is confirmed clean. Given that limit, the licensing mismatch, and the concentration described 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 research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
