Audit log

Every state-changing event for ValueDefi: 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.

   Score: 34 → 34 (no score change)
   A small sample of core claims was checked: the first-exploit date and price drop, and the second and third exploit dates, amounts and mechanisms. These are supported by CoinDesk and REKT. Problems found: the '$8.5 million' attribution to BASv2 appears to be a mix-up with 8.5M BDO tokens, the 'nine of 16 pools' figure was not found in REKT, and the rekt-leaderboard statement is attached to the wrong exploit in the timeline. The coverage of the many remaining claims is thin, so this is a partial review. No current-status information was obtained.

   Score: 34 → 34 (no score change)
   Of 6 claims checked, none were contradicted outright and 1 could not be found in the sources (claim_findings[1], the 'nine of 16 pools' figure), giving 17% unverifiable or disputed, which is the minor-issues band. Two further claims were only partly supported: the '$8.5 million' figure attributed to BASv2 appears to be a mix-up with 8.5M BDO tokens (claim_findings[0]), and the rekt leaderboard statement is attached to the third exploit when it follows from the second (claim_findings[2]). The core dates, amounts and mechanisms of all three exploits were confirmed. The reviewer checked only a small sample, with 0.4 confidence, so the penalty is kept at the low end of the band. No shutdown or other omission was reported.
