Rubicon

Rubicon’s measured liquidity perimeter now spans Optimism, Ethereum, Arbitrum and Base and aggregates three investable market-making systems: Classic order-book reserves and legacy Optimism Bath vaults, Aquila v2 constant-product pools and v3 concentrated-liquidity pools. DefiLlama measured $219,575 on 2026-08-16. Each measured claim holds inventory so others can trade, leaving the supplier exposed to fills or reserve rebalancing. The version-1 AMM-LP dossier remains exact, but the former Base-only/order-book-only description was stale.

Review triggers: events that reopen the verdict
• Ships a separately accounted product whose client return does not depend on market-making inventory, adverse fills or pool reserve rebalancing
• For any exact market or pool, approved assets, contracts, authorities, bounds, incident history and a proposed-size stressed inventory exit are independently verified

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism and aggregate-class applicability

Rubicon Classic is an Oasis-style onchain order book; Optimism BathTokens pool assets and place maker liquidity. The current measured aggregate also includes Aquila v2, a constant-product AMM fork, and v3 concentrated-liquidity factories. Although execution curves differ, the investable balance in each system is inventory offered to traders and can exit in a different asset mix or after adverse fills. AMM-LP is therefore the closest existing fundamental class for the surveyed liquidity claims.

Corrected contracts and chain perimeter

The current adapter lists Classic markets on Optimism, Arbitrum and Base, seven legacy Bath pools only on Optimism, Aquila factories on Ethereum, Optimism, Arbitrum and Base, and v3 factories on the same four chains. The API attributed $219,575 across all four on 2026-08-16, led by Optimism and Base. This supersedes the stale Base-only four-pool description.

Control, lifecycle and exit applicability

Classic makers depend on order cancellation or counter-orders and custody in the market or Bath vault; Aquila and v3 LPs depend on pool reserves, price ranges, factory and pool code and chain settlement. The current Gladius intents system is a separate non-custodial trading path and is not counted as client TVL here. Proposed-size exit must therefore be proven separately for each exact Classic, Bath, v2 or v3 position rather than inferred from aggregate protocol TVL.

Comparison and measurable reopening test

Rubicon Classic changes execution from an AMM curve to explicit offers, but it does not remove adverse-selection or inventory-conversion risk for passive makers. Aquila and v3 map directly to constant-product and concentrated-liquidity alternatives. Reopen only for a separately accounted non-market-making product, or after an exact pool or maker mandate demonstrates approved assets, immutable bounds, complete authorities and a proposed-size stressed exit without unacceptable inventory conversion.

Class rule

The amm lp 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.

Sources

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.
