{"investigation":{"slug":"twinstake","entity_name":"Twinstake","trust_score":68,"severity_base":null,"score_modifier":0,"confidence":0.5,"status":"published","content_type":"investigation","summary":"Twinstake is a non-custodial institutional staking provider, formed in 2022 as a joint venture between Ethereum infrastructure firm Nethermind and WebN Group, a blockchain incubator backed by hedge-fund billionaire Alan Howard. It runs validators across multiple proof-of-stake networks for institutional clients, who retain custody of assets through third-party custodians. No regulatory actions, lawsuits, or confirmed security incidents involving Twinstake were found; the company's co-founder's WebN backer announced it was closing in February 2026, and a secondary on-chain source shows isolated validator slashing penalties on one smaller network that could not be independently corroborated.","sections":[{"content":"Twinstake was established in 2022 as a joint venture between Nethermind, an Ethereum client and infrastructure company, and WebN Group, a blockchain and Web3 incubator backed by billionaire hedge-fund manager Alan Howard. Industry reporting describes Nethermind and WebN as remaining majority shareholders in the venture. Twinstake's team page identifies Tomasz Stańczak, also the founder and chief executive of Nethermind, as a founder of Twinstake, though sources disagree on whether he currently holds the title of chief executive or chairman of Twinstake's board. The company is reported to be registered as Twinstake Ltd. in the Cayman Islands, with a UK operating entity (Twinstake UK Limited) used in some job postings. In February 2026, CoinDesk reported that WebN Group was closing after what a source described as having 'successfully completed its mission'; WebN's portfolio was reported to include Twinstake, KAIO, TruFin and Geometry. The reporting states the closure was not expected to affect Howard's broader digital-asset interests, but available sources do not clarify what became of WebN's equity stake in Twinstake after the wind-down.","heading":"Corporate structure and ownership","sources":[{"url":"https://www.fintechscotland.com/fintech/nethermind/","name":"Nethermind fintech profile (FinTech Scotland)","type":"other","credibility":2},{"url":"https://www.mexc.com/news/797882","name":"Billionaire Alan Howard's crypto incubator WebN closes down (CoinDesk, via MEXC republish)","type":"news_article","credibility":2},{"url":"https://web3connect.com/partner/twinstake","name":"Twinstake Ltd. partner listing (Web3Connect)","type":"other","credibility":3}],"severity":"low"},{"content":"Twinstake describes itself as a non-custodial staking provider for institutional clients, offering an API for programmatic staking, a 'concierge' staking service with dedicated customer support, and a reporting portal. Clients are said to retain control of underlying assets by staking through their own custodian or wallet provider rather than transferring assets to Twinstake. The company has announced integrations and validator-set memberships across a range of proof-of-stake networks, including joining the IOTA Genesis validator set (2025), partnering with Utila to offer TON staking (December 2024), being added as a staking provider to Virtune's crypto exchange-traded product programme (July 2026), offering staking for Radix (XRD), and participating in Jupiter's jupSOL validator set on Solana. In 2025, Nethermind and Twinstake proposed migrating roughly 7,400 Nethermind-operated validators from Lido's Curated Set to Twinstake, a move consistent with Nethermind's reported shareholding in Twinstake.","heading":"Business operations","sources":[{"url":"https://www.crowdfundinsider.com/2025/04/238254-institutional-grade-staking-twinstake-joins-iota-genesis-validator-set/","name":"Institutional-Grade Staking: Twinstake Joins IOTA Genesis Validator Set (Crowdfund Insider)","type":"news_article","credibility":2},{"url":"https://www.crowdfundinsider.com/2024/12/234029-digital-assets-utila-and-twinstake-to-enable-institutions-with-ton-staking-solutions/","name":"Digital Assets: Utila and Twinstake to Enable Institutions with TON Staking Solutions (Crowdfund Insider)","type":"news_article","credibility":2},{"url":"https://www.placera.se/pressmeddelanden/virtune-hyperliquid-etp-virtune-adds-twinstake-as-an-additional-staking-provider-within-its-crypto-etp-programme-20260714","name":"Virtune adds Twinstake as an Additional Staking Provider within its Crypto ETP Programme","type":"news_article","credibility":2},{"url":"https://twinstake.io/news/twinstake-now-offers-institutional-staking-of-radix-xrd","name":"Twinstake now offers institutional staking of Radix (XRD)","type":"official","credibility":2},{"url":"https://research.lido.fi/t/nethermind-no-curated-validator-set-transfer-to-twinstake/10288","name":"Nethermind NO Curated Validator set transfer to Twinstake (Lido Research Forum)","type":"community_report","credibility":2}],"severity":"low"},{"content":"A third-party validator-slashing dashboard (kjnodes.com) lists two penalty events in late 2024 attributed to a Twinstake-operated validator on the MANTRA chain: an approximately 4,000 MANTRA penalty recorded around October 2024 (logged as the validator's first offense) and a substantially larger penalty of approximately 35,873 MANTRA recorded around November 2024 (logged as a second offense). No independent news coverage, blockchain explorer confirmation, or statement from Twinstake addressing these events was found, and the dashboard does not specify whether the penalties resulted from downtime, double-signing, or another cause.
