In an Aug. 31 update, Cronos said the restarted chain was producing blocks from block 90,896,189, with a timestamp of 23:49:01 UTC on Aug. 30.<\/p>\n<p>The network said it was fully back online, but added that some protocols, RPC providers, explorers and bridges could take longer to recover. Cronos also said it was monitoring the chain for stability and would publish a full postmortem. Those details superseded a 05:24 UTC update on Aug. 31 that said the network remained halted while the investigation continued.<\/p>\n<p>Cronos had announced the halt on Aug. 30 after identifying an exploit at Tectonic, a decentralized lending protocol on the chain. The response made the wider blockchain, rather than only Tectonic, unavailable while validators and security teams assessed the incident.<\/p>\n<div class=\"cs-article-embed\">\n<p> <span class=\"cs-article-embed__related-reading\">Related Reading<\/span><\/p>\n<h3 class=\"cs-article-embed__title\">EVM network halts block production after supply exploit as TON connection remains dark<\/h3>\n<\/p>\n<p> <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\"> <i class=\"fa-light fa-arrow-up-right\"\/> <\/span> <\/div>\n<p>Tectonic separately acknowledged an incident and told users not to interact with the protocol until it confirmed that doing so was safe.<\/p>\n<h2>How the Tectonic exploit unfolded<\/h2>\n<p>Onchain researcher Weilin Li attributed the exploit to manipulation of TONIC, Tectonic&#8217;s thinly traded governance token. According to Li&#8217;s analysis, the attacker inflated TONIC&#8217;s price and used the token as collateral to borrow other assets from Tectonic.<\/p>\n<p>The protocol&#8217;s documentation lists a 20% collateral factor for TONIC in a parameter table dated May 2025. However, that historical table does not establish the configuration at the time of the incident.<\/p>\n<aside id=\"cs-inline-newsletter-1\" class=\"cs-inline-newsletter\" data-inline-newsletter=\"\" data-newsletter-placement=\"article-midpoint\" data-newsletter-pending-label=\"Joining\u2026\" data-newsletter-pending-status=\"Joining the Daily Brief\u2026\" data-newsletter-email-required-message=\"Before sending, please provide your email address.\" aria-labelledby=\"cs-inline-newsletter-1-title\" aria-describedby=\"cs-inline-newsletter-1-copy\">\n<div class=\"cs-inline-newsletter__inner\">\n<div class=\"cs-inline-newsletter__content\"> <span class=\"cs-inline-newsletter__eyebrow\"> <i class=\"fa-regular fa-envelope\" aria-hidden=\"true\"\/> The Daily Brief <\/span><\/p>\n<h2 id=\"cs-inline-newsletter-1-title\" class=\"cs-inline-newsletter__title\">The signal, before the noise.<\/h2>\n<p id=\"cs-inline-newsletter-1-copy\" class=\"cs-inline-newsletter__copy\">Start your day with the crypto stories moving markets, decoded by CryptoSlate\u2019s editors.<\/p>\n<\/div>\n<div class=\"cs-inline-newsletter__form-shell\">\n<p class=\"cs-inline-newsletter__form-heading\">One email.

He estimated that only about $6 million was bridged to Ethereum before Cronos halted, leaving most of the affected assets on the network. The figures and attack mechanism remain Li&#8217;s assessment rather than an official accounting.<\/p>\n<div class=\"cs-article-embed\">\n<p> <span class=\"cs-article-embed__related-reading\">Related Reading<\/span><\/p>\n<h3 class=\"cs-article-embed__title\">Chain shutdown strips BounceBit token utility after authorization flaw exposes 286M tokens<\/h3>\n<\/p>\n<p> <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\"> <i class=\"fa-light fa-arrow-up-right\"\/> <\/span> <\/div>\n<h2>What the Cronos restart changes<\/h2>\n<p>The restart relied on restoring the chain state to before the Tectonic exploit. Cronos said node operators could restart on version 1.7.8 using updated mainnet snapshots. The network did not say in the cited update how the rollback would affect all transactions submitted during the discarded period.<\/p>\n<p>The difference between Li&#8217;s total estimate and the reported bridge flow helps explain why the validator halt may have limited onward movement. However, Cronos and Tectonic have not published a confirmed loss, an official root-cause analysis or a complete account of how attacker-controlled assets will be handled.<\/p>\n<p>Crypto.com CEO Kris Marszalek said the company&#8217;s app and exchange were unaffected, were operating normally and had sent security staff to assist Cronos. That assurance applies to Crypto.com&#8217;s services, not to Tectonic depositors.<\/p>\n<div class=\"cs-article-embed\">\n<p> <span class=\"cs-article-embed__related-reading\">Related Reading<\/span><\/p>\n<h3 class=\"cs-article-embed__title\">MANTRA Chain is back online, but silent code changes spark developer concerns<\/h3>\n<\/p>\n<p> <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\"> <i class=\"fa-light fa-arrow-up-right\"\/> <\/span> <\/div>\n<p>The immediate uncertainty has shifted from when Cronos will restart to how quickly connected services recover and what the promised postmortem establishes.
