Audit log

Every state-changing event for SolvBTC: 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: 38 → 38 (no score change)
   The core March 2026 BRO exploit facts (date, amount, mechanics, contract, response) are well supported. Two defects were found: the page misattributes to Halborn a 'not reentrancy' view when Halborn calls it a classic reentrancy exploit, and the confirmation timeline date is likely March 5, not March 6. Several secondary claims (TVL, tokenomics, reserve composition, audits) were not verified in this pass. No shutdown or sanction was found.

   Score: 38 → 23 (-15)
   Of 11 claims checked, 2 were disputed and 4 could not be verified, giving a disputed rate of about 55%. The core March 2026 exploit facts (date, amount, mechanics, response) were confirmed (claim_findings[2], [3]). However, the page misattributes to Halborn a 'not reentrancy' view when Halborn calls it a classic reentrancy exploit (claim_findings[0]), and the confirmation date appears to be March 5, not March 6 (claim_findings[1]). The TVL figures, audits, DeFiLlama figure and a named role could not be confirmed, so the penalty is kept at the low end of the band because the reviewer's confidence was moderate and most unverified items were simply not checked.
