Audit log

Every state-changing event for ACryptoS: moderation decisions on community submissions, plus corrections and updates from the news pipeline. URL-based decisions are designed to carry three independent witnesses — the original source, an Internet Archive snapshot, and a Solana memo signed by our publicly-disclosed publisher key. Archive coverage is still being backfilled, so each decision below reports its own snapshot status rather than assuming one exists.

Security firm SlowMist recorded losses of approximately $665,000 (reported variously as $665,000 and $665,429) resulting from the incident. According to post-attack analysis reported by crypto.news, the root cause was a missing input-validation check in a multi-token deposit function (referred to in reporting as depositMulti), which allowed an attacker to submit a token list shorter than the number of assets a vault expected. This discrepancy let the attacker mint a disproportionately large share of a vault's total shares using only a small deposit, which could then be redeemed against the vault's actual pooled assets at the expense of other depositors. These specific mechanics are drawn from secondary reporting rather than an official post-mortem from ACryptoS or a published SlowMist report, and should be treated as the outlets' interpretation of the exploit pending primary confirmation.","heading":"November 2026 Vault Exploit","severity":"critical","sources":[{"credibility":2,"name":"How small deposits drained 77 ACryptoS vaults and what users can still withdraw - crypto.news","type":"news_article","url":"https://crypto.news/how-small-deposits-drained-77-acryptos-vaults-and-what-users-can-still-withdraw/"},{"credibility":3,"name":"ACryptoS Vault Exploit: How Tiny Deposits Drained 77 Pools - capwolf.com","type":"news_article","url":"https://capwolf.com/acryptos-vault-exploit-how-tiny-deposits-drained-77-pools/"}]},{"content":"Following the exploit, ACryptoS disabled the deposit function across affected vaults while leaving the withdrawal function open. Reporting notes that withdrawals, while technically available, only pay out against whatever assets remain in each vault, meaning affected users may not recover their full pre-exploit balances. The team reportedly stated that it no longer has the resources to continue maintaining the protocol and urged users to withdraw their funds as soon as possible, which several outlets characterize as a de facto shutdown or deprecation of the protocol. One source referenced a 10% bounty offered for return of exploited funds, though no distribution plan, timetable, or reimbursement commitment has been published. No official statement from ACryptoS's own channels (website, X/Twitter, or Discord) could be independently located during this investigation; the response described here is as relayed by crypto-news outlets and incident trackers such as ChainCatcher, and should be considered secondary-sourced pending direct confirmation.","heading":"Team Response and Operational Wind-Down","severity":"high","sources":[{"credibility":2,"name":"How small deposits drained 77 ACryptoS vaults and what users can still withdraw - crypto.news","type":"news_article","url":"https://crypto.news/how-small-deposits-drained-77-acryptos-vaults-and-what-users-can-still-withdraw/"},{"credibility":2,"name":"ChainCatcher coverage of ACryptoS exploit","type":"news_article","url":"https://www.chaincatcher.com/en/article/2302840"}]},{"content":"As of this writing, no official SlowMist report, formal post-mortem, or primary statement from ACryptoS has been independently located to corroborate the loss figure, root-cause mechanics, or stated wind-down. All information currently available derives from secondary crypto-news coverage (crypto.news, ChainCatcher, capwolf.com) summarizing incident-tracker and SlowMist-attributed figures.

Reporting attributes the loss to a missing input-validation check in a multi-token deposit function that allowed attackers to mint a majority of vault shares with minimal deposits. The team disabled deposits, left withdrawals open against remaining vault assets, and stated it no longer has the resources to continue maintaining the protocol, effectively signaling a wind-down.","timeline":[{"date":"2026-11","date_evidence":"Security firm SlowMist recorded approximately $665,000 in losses from an 8 November ACryptoS exploit affecting 77 vaults across Arbitrum, BNB Chain, Polygon, Base and Optimism.","date_original":"2026-11-08","event":"Exploit drains an estimated $665,000 from 77 ACryptoS vaults across five chains via a missing input-validation flaw in a multi-token deposit function.","source":"crypto.news","source_url":"https://crypto.news/how-small-deposits-drained-77-acryptos-vaults-and-what-users-can-still-withdraw/"},{"date":"2026-11","date_original":"2026-11-09","event":"ACryptoS exploit is publicly reported; the team disables deposits, keeps withdrawals open against remaining vault assets, and signals it can no longer resource protocol maintenance.","source":"crypto.news / ChainCatcher","source_url":"https://www.chaincatcher.com/en/article/2302840"}]},"v":1}
