Ensuro
Ensuro eTokens fund solvency capital for insurance portfolios on Ethereum and Polygon. LPs earn a cost-of-capital charge from premiums and absorb unexpected claims after the related premium and junior layers. This is insurance underwriting, not lending, AMM liquidity or the subject of the existing off-chain-credit record. No more basic standing class applies, so capacity decides the judgment: the 2026-08-15 survey showed approximately $1.99M, far below the version-1 size floor. We do not open an individual review until it clears that floor.

The research file
Mechanism applicability
An Ensuro LP deposits stablecoins into an eToken pool tied to named insurance risks. Active policies lock part of the pool’s capital as solvency capital, and their premiums pay an ongoing cost-of-capital return. If claims exceed expected pure premiums, Premiums Accounts borrow first from junior eTokens and then from senior eTokens, reducing LP token supply and return. This is direct capacity for insurance losses, not a passive stablecoin account.
Current observation and perimeter
The DefiLlama protocol API read on 2026-08-15 classified Ensuro as Insurance and reported approximately $1.99M, with about $1.94M on Ethereum and $0.05M on Polygon. Current documentation, updated in 2026, describes live eToken pools, risk partners, junior and senior tranches, and Bermuda segregated capital pools. The chains have not changed. Current TVL is above the stale $1.3M observation but remains far below the size floor.
Control, loss and exit applicability
Risk Modules run for insurance partners add, price and settle policies through trusted parties, calculations or oracles. Ensuro’s quantitative team sets collateralization and monitors pricing. Claim losses use up won and active premiums before they reach junior and senior eToken capital. A holder may redeem one-for-one only when the capital left exceeds locked solvency requirements. High use or claim periods can restrict withdrawals, and legal recourse is limited to the related segregated pool.
Why the class rule decides
The existing off-chain-credit record does not accurately describe an insurance-solvency claim, and the research set has no insurance-underwriting class. At roughly $1.99M, however, a $1M to $8M advised allocation would dominate the whole system before we test portfolio loss data, partner resolution, tranche attachment, legal rights or stressed redemption. The shared v1 rule for protocols below material size therefore decides the judgment. We do not open a full individual insurance review until sustained TVL clears the size floor.
Research status
This is a capacity-unproven record for Ensuro, 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.

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. |
| Polygon PoS | Rejected | Mixed control | a public validator set orders transactions, but a 5-of-9 multisig can instantly upgrade staking and canonical bridge contracts, while a 5-of-8 controls custom child tokens. |
