Verify a decision
Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.
How verification works
- We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (
payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction. - We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
- You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is
AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. Yearn Ether (yETH) is the liquid staking vault product of Yearn Finance, a legitimate and long-running DeFi yield aggregator founded in 2020 with a verifiably fair token launch. All four loss events cited on the page — the 2021 DAI flash loan exploit, the 2023 Euler indirect exposure, the 2023 yUSDT legacy misconfiguration exploit, and the 2025 yETH arithmetic underflow — were external attacks on legacy or specific contracts; Yearn's current v2/v3 infrastructure was unaffected in each case and holds $150M+ TVL. The protocol responded to each incident with public post-mortems, treasury-backed recovery plans (YIP-90 deploys ~1,600 ETH), and governance votes — behaviour characteristic of a legitimate operator, not a scammer. The current score of 28/WARNING is misaligned: WARNING implies elevated fraud risk or an unresolved severe incident, but the incidents are externally attributed and under active remediation. The correct band is CAUTIONARY (50-69) to signal material security history and meaningful unrecovered losses (~$6.6M from the 2025 exploit still outstanding), while acknowledging this is a legitimate protocol with no regulatory sanctions and ongoing active operation.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
