   The Dango investigation page's core factual claims — the $3.6M seed round, the April 13 2026 exploit mechanics ($1.9M USDC via insurance fund sign error), the $410,010 bridged to Ethereum, chain pause with SEAL-911 engagement, and white hat fund return — are all confirmed by multiple independent sources. Three claims are only partially supported: the specific investor entity name (Delphi Labs vs. Delphi Ventures, minor), the January 2025 testnet 2.0 campaign start date (evidence suggests a later launch), and the specific April 15 resume date post-exploit. The most significant structural issue is that all six section content fields are empty, leaving 12 cited URLs unanchored to any visible claim text.

   All 12 claims reviewed returned zero disputed findings. Nine claims are fully confirmed by multiple independent sources; three are partially supported but involve only minor imprecision — an investor entity name variant (Delphi Labs vs. Delphi Ventures, claim_findings[2]), an uncertain campaign start date (claim_findings[10]), and an unverified specific post-exploit resume date (claim_findings[11]). The core factual record — the $3.6M seed round, the April 13 2026 sign-error exploit draining $1.9M USDC, the $410,010 bridged to Ethereum, chain pause with SEAL-911 engagement, and white hat full fund return — is confirmed across multiple credible sources. Three high-priority coverage gaps (missing on-chain transaction hashes, no official team postmortem, and empty section content fields) indicate the page needs substantive expansion but do not constitute factual failures warranting revision or denial.
