ATOMA

ATOMA accepts USDC into an Arbitrum vault, issues AVS shares at NAV and automatically opens offsetting long and short positions across manager-selected perpetual venues to capture funding spreads and points. Depositors do not select or continuously control the venues, weights, rebalances or margin accounts. The 2026-08-16 survey measured about $0.30M. That delegated, changing strategy perimeter is more fundamental than size, so the version-1 delegated-allocation dossier controls.

Review triggers: events that reopen the verdict
• A named vault publishes enforceable venue and leverage bounds, mapped authorities and audits, reconciled positions and NAV, realized loss history, and a tested proposed-size redemption

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-16.

The research file

Mechanism applicability

ATOMA states that users deposit USDC, receive AVS at current NAV and redeem AVS for USDC. Between those actions the vault simultaneously opens long and short positions across selected perpetual exchanges, automatically rebalances and accumulates venue points. The receipt is therefore a claim on a managed multi-venue strategy rather than a direct user-selected lending or staking position.

Control, loss and exit applicability

ATOMA chooses the perpetual venues and runs the positions automatically. Each venue introduces its own margin, oracle, liquidation, funding and contract controls; Nado documents that funding can change sign and that maintenance-margin failure permits liquidation, while Extended exposes hourly funding and leverage parameters. ATOMA advertises redemption at NAV, but the public page does not establish manager roles, upgrade and emergency powers, valuation bounds, withdrawal liquidity, audit scope or loss allocation for the exact vault.

Current observation and perimeter

The DefiLlama API read on 2026-08-16 classified ATOMA as Basis Trading and reported approximately $0.30M entirely on Arbitrum. ATOMA’s current site names Extended and Nado in the core strategy presentation and links an Arbitrum vault contract; other referral links and “Index” pages may describe additional campaigns. This record covers the measured USDC/AVS managed vault, not a direct account a client independently operates at a venue.

Why the class rule decides

Return and principal depend on ATOMA’s continuing selection, sizing, hedging and rebalancing across downstream perpetual venues. A delta-neutral target does not eliminate basis, funding inversion, liquidation, venue, oracle or operator risk. The shared version-1 delegated-allocation dossier therefore controls before subscale capacity. Reopen only after a named vault has immutable or bounded mandates, mapped authorities and audits, independently reconciled positions and NAV, loss history and a tested proposed-size redemption.

Class rule

The delegated allocation class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

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.
