Thesauros
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
Thesauros is a stablecoin yield protocol on Arbitrum that allocates deposits across lending and liquidity venues under preset risk and performance parameters, paying out through a yield-bearing wrapped stablecoin. DefiLlama measured $51,203 across four chains on 2026-08-16, only 0.05% of the $100M floor. The file remains rejected on size before allocator control, downstream-venue, NAV, wrapper, and stressed-exit diligence.
- TVL sustained above $100M for 30 days
The research file
Mechanism applicability
Thesauros accepts supported stablecoins and issues a wrapped stablecoin that accrues reported rewards while contracts allocate among Aave, Hyperliquid, Morpho, Curve and other venues. The depositor therefore owns an allocator wrapper with lending and AMM look-through, not a direct claim on one frozen market.
Control and assurance applicability
Allocation follows protocol-defined risk and performance parameters, leaving venue selection and changes to the Thesauros system. Two published Hexens reports provide code-review evidence, but public materials do not make strategy selection immutable or eliminate downstream contracts, token depeg, valuation, and governance risks.
Exit applicability
The site markets withdrawal at any time with no lockup. Actual redemption still requires available stablecoin liquidity or successful downstream unwinds; a yield-bearing wrapper does not guarantee that each venue can return par simultaneously under stress.
Why the dossier still applies
DefiLlama measured $51,203 across Plasma, Base, Arbitrum and Monad on 2026-08-16, 0.05% of the $100M floor. Reopen after TVL remains above $100M for 30 days, then reconcile positions and NAV, strategy-change authority, venue caps, audits and incidents, wrapper loss rules, and a proposed-size multivenue redemption test.

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.
| Chain | Verdict | Grade | Control constraint |
|---|---|---|---|
| Plasma | Rejected | freezable | the production validator committee is permissioned and the public docs still describe decentralization as a phased future rollout with no fixed access timeline. |
| Base | Approved · limits | hybrid | Coinbase — one regulated US company — operates the only sequencer, and admin keys can upgrade bridge contracts within ~7 days. |
| Arbitrum One | Approved · limits | hybrid | a single sequencer orders >99% of transactions and admin keys can upgrade bridge contracts on a ~7-day timelock. |
| Monad | Approved · limits | crypto-backed | 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. |
