Gearbox
Gearbox is a credit protocol: passive lenders fund pools that borrowers draw on for leveraged positions. It held about $4.8M in TVL across Ethereum, Etherlink, Plasma, and Monad at the 2026-08-14 survey, below the size floor we require before a protocol can hold advised client money. The lending side would still need review on its own merits at scale, since the borrowers are levered traders. We do not open the individual review until Gearbox clears the size floor. An advised book of $1M to $8M from one practice becomes the exit crush at this scale, whatever the protocol’s quality.
- TVL sustained above the retired TVL threshold for 30 days

The research file
Applicability to the surveyed record
Gearbox documents on-chain credit infrastructure that links passive ERC-4626 liquidity pools to borrowers who operate through constrained Credit Accounts. Lenders receive non-rebasing Diesel Tokens, borrower interest raises their exchange rate, and the pools assign capital to Credit Suites under debt ceilings. These terms establish a pooled-lending product rather than a direct strategy position.
Current observation and perimeter
The DefiLlama protocol API read on 2026-08-15 classified Gearbox as Lending and showed approximately $17.39M TVL, still well below the shared v1 size floor. It reported live balances across Ethereum, Arbitrum, Binance, Etherlink, Hemi, Lisk, Monad, Optimism, Plasma, Somnia, and Sonic. The registry now covers that current eleven-chain survey.
Control and exit applicability
Market curators set Credit-Suite debt ceilings and risk parameters. Credit Accounts limit borrowed capital to approved assets and adapters, while liquidation rules enforce solvency. Lenders can withdraw at once only when a pool has enough unborrowed liquidity. High use can block exit, and an emergency admin can pause pool deposits and LP-token withdrawals or restrict borrowing and collateral operations.
Why the class rule decides
The shared v1 below-size dossier decides the result because Gearbox remains below the size floor despite its clearly documented multi-chain pooled-credit structure. Reopen after DefiLlama TVL remains above the size floor for 30 consecutive days. Then review each live instance and curator, debt ceilings, Credit-Suite allocations, oracle and liquidation design, bad-debt and incident history, withdrawal liquidity under stress, emergency powers, and named lending alternatives.
Research status
This is a capacity-unproven record for Gearbox, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.
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.
| Chain | Verdict | Control | Control constraint |
|---|---|---|---|
| Ethereum | Approved | No freeze key | No sequencer, no upgrade key, no operator who can be compelled. Rule changes require social consensus. |
| Arbitrum One | Approved with limits | Mixed control | a single sequencer orders >99% of transactions and admin keys can upgrade bridge contracts on a ~7-day timelock. |
| BNB Smart Chain | Rejected | Issuer can freeze | the validator set concentrates around one company, and the chain has been halted by decision. |
| Monad | Approved with limits | Governed, no freeze | the L1 has a public validator path, but its short production record, single initial client lineage, and Foundation-directed delegation keep stake and operations concentrated. |
| OP Mainnet | Rejected | Mixed control | Ethereum forced inclusion limits sequencer censorship, but the Foundation and Security Council can co-sign an immediate upgrade before a client can exit. |
| Plasma | Rejected | Issuer can freeze | the production validator committee is permissioned and the public docs still describe decentralization as a phased future rollout with no fixed access timeline. |
