The capital pool is on chain and held 40,651 ETH-equivalent ($92.3 million) on November 1, 2026, 583% of its minimum capital requirement; 18.7 million USDC of that is a 'Cover Re investment' figure the board's Safe enters for assets held outside the pool contracts. Nexus has paid $24.7 million of claims since 2020, and no entity behind it publishes audited accounts. AltStreet score: 40.8 (C-), scored November 1, 2026.

Members pass KYC, pay a 0.002 ETH fee and can then buy cover, stake NXM to back cover, or hold NXM, the token that represents a share of the capital pool. Three questions frame it. Will a claim be paid: Nexus says its cover 'is not a contract of insurance' and involves 'only a discretion, not a legal obligation, to pay'. Since November 2025 every claim has been decided by a Claims Committee of three, two of whom sit on the five-person Advisory Board that can also reverse claim votes for fraud. The record so far: 104 claims paid on chain since 2020, $24.7 million in all, including Rari, FTX, Euler and, in October 2026, a $6.1 million Neutrl depeg claim paid alongside a $6.7 million purchase of the claimant's recovery value. What backs it: the capital pool held 40,651 ETH-equivalent ($92.3 million) at the pin, 583% of the minimum capital requirement the contracts compute. That figure includes 18.7 million USDC described as a 'Cover Re investment', a number the board's 3-of-5 Safe enters for the Re-related holdings and the Neutrl recovery, which sit outside the pool contracts; as a sensitivity, the pool without it is $73.4 million. The pool has fallen 60% in ETH since the end of 2023, mostly through NXM redemptions, while active cover rose. Who controls it: the same five people are the board, the directors of the UK company and the council of the Panama foundation that received the mutual's assets in 2022. None of these entities publishes audited accounts, and the members' agreement bars suits against other members or the mutual's property without the consent of at least half of other members. - **$92.3M** Capital pool on chain at November 1, 2026: 40,651.5 ETH-equivalent at $2,269.67, equal to the contract's own pool value to the wei; as a sensitivity, $73.4M without the board-entered Cover Re figure. - **18.7M USDC** Holdings outside the pool contracts, counted through SafeTracker at a figure the Advisory Board Safe enters with no timelock: 12.0M carried from the 2024 Re investment (since redeemed into reUSDe and a Fern Re commitment) and 6.74M paid on October 15, 2026 for the recovery value of a Neutrl claimant's NUSD position; 20.3% of the counted pool. - **$24.7M** Claims paid on chain since 2020 across 104 accepted claims; the docs' '$18.5M ... as of August 2026' matches the chain to that date, and the public claims ledger ends at claim #37, before the two October 2026 Neutrl claims. - **2 of 3** Claims Committee members who also sit on the five-person Advisory Board; two of the three assessors decide each claim, and the board can reverse votes for fraud. - **60%** Fall in the capital pool measured in ETH from 101,320 (end 2023) to 40,652; NXM redemptions through the Ramm returned 68,041 ETH from January 2024 to the pin, while active cover rose from 23,278 to 33,446 ETH. - **None** No public audited financial statements located for any Nexus entity; the UK company's accounts are unaudited in every year and two years were filed as dormant.

Its cover is discretionary, its claims are decided by three people tied to a five-person board that also runs the treasury, upgrades and most staking, one-fifth of its counted capital is a figure that board reports, and none of its entities publishes audited accounts. **Best for** - Crypto funds and protocols that want cover for specific on-chain risks, read the wording, and accept discretionary payment. **Look elsewhere if** - You need a legally enforceable insurance contract. - You need audited financial statements. - You want yield from staking without exposure to claims, governance and pool size. **Strengths** - $24.7 million of claims paid since 2020, including several multi-million events. - Capital pool, MCR, covers and claims readable on chain and matching the contracts. - Smart contracts audited by iosiro for each release; 24-hour timelock on proposals. **Limitations** - Discretionary cover decided by three assessors, two of them board members, with no appeal stage. - One-fifth of the counted pool is a board-entered figure for off-pool holdings; the pool has fallen 60% in ETH since end-2023. - No audited accounts; a member agreement that limits suits; undisclosed counterparty role of a board member. - Largest claim settled with the recovery value bought for cash and counted in the pool at that price, on terms that are not public. ## Who it fits | Investor | Fit | Why | | --- | --- | --- | | Crypto funds and protocols seeking cover for specific risks | neutral | | | Investors seeking yield from NXM staking | poor-fit | | | Anyone needing a legal right to be paid | poor-fit | | ## Questions **Is Nexus Mutual legit?** Nexus Mutual has operated since 2019 and has paid $24.7 million of claims on chain, including large payouts after Rari, FTX and Euler, and AltStreet located no enforcement action against it. Its cover is discretionary and 'not a contract of insurance', claims are decided by a three-person committee tied to its board, part of its counted capital is a figure the board enters, and AltStreet located no public audited accounts for any of its entities. **Is Nexus Mutual cover insurance?** No, by its own description. Nexus says its cover 'is not a contract of insurance' and involves 'only a discretion, not a legal obligation, to pay out'. Claims are decided by the Claims Committee; a denied claimant can file a new claim, and the Member Agreement sends disputes to arbitration. **Can US residents use Nexus Mutual?** The United States is not on Nexus's list of 27 restricted countries, and AltStreet found no US-person exclusion in the membership terms, Member Agreement or protocol wordings. Whether discretionary cover is permitted where you live is a question for your own adviser. **How much has Nexus Mutual paid in claims?** On chain, $24.68 million across 104 accepted claims from 2020 to November 1, 2026, including 6.14 million USDC for a Neutrl depeg claim in October 2026, settled together with a $6.74 million purchase of the claimant's recovery value. Nexus's docs give $18.5 million as of August 2026, which matches the chain to that date, and its public claims ledger does not yet list the two Neutrl claims. **What is NXM and can I sell it?** NXM is the membership and capital token. Members can redeem it through the Ramm at a price that starts 1% below book value and falls with the size of the sale (a quoted 0.0259 ETH at the pin, a snapshot), subject to the mechanism's liquidity and a cumulative sell limit with about 12,539 ETH left. wNXM, a third-party wrapper, trades freely. **Who controls Nexus Mutual?** A five-person Advisory Board (Hugh Karp, Roxana Danila, Reinis Melbardis, Graeme Thurgood, Lee McClelland), who are also the directors of Nexus Mutual Limited and the council of Terrapin International Foundation. Upgrades need three board votes and a 24-hour wait; members can replace board members by vote. ## Evidence appendix Platform website captured November 1, 2026.
