Audit log

Every state-changing event for Swaprum: 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.

   The core facts hold: about 1,628 ETH (~$3M) was drained, about 1,620 ETH went through Tornado Cash, the social accounts were deleted, and there have been no arrests or recoveries. Three points need attention. The CertiK major-finding count (four on the page, three in Decrypt) needs checking against CertiK's report. The Hope Finance and largest-Arbitrum-scam comparison is unsupported by the fetched sources. QuillAudits-specific details could not be read because of a 403.

   The core allegations hold up: the roughly 1,628 ETH (~$3M) theft, the ~1,620 ETH routed through Tornado Cash, the deletion of the team's accounts, and the absence of reported arrests were all confirmed by independent news sources (claim_findings[0], [1], [7], [9]). About 20% of claims could not be verified or were unsupported: the Hope Finance / largest-Arbitrum-scam comparison (claim_findings[4]) and the CertiK audit start date (claim_findings[8]) were not found in any consulted source. The CertiK major-finding count (four on the page, three in Decrypt) is unresolved (claim_findings[2], [3]), and the timeline entries carry no sources. The page's account of the QuillAudits transaction details could not be checked because the source refused access, which says nothing against the claim.
