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. Phantom Wallet is a legitimate, venture-backed non-custodial wallet operator with $268M in institutional funding, a $3B valuation as of January 2025, 15M+ monthly active users, and a positive March 2026 CFTC no-action letter — the first ever granted to a self-custodial wallet. None of the incidents documented on the page constitute fraud by Phantom itself: the August 2022 Solana exploit was definitively traced to Slope Wallet's server-side key storage failure; the Demonic vulnerability was patched before any confirmed exploitation; the 2024 supply chain attack had zero impact on Phantom; and the fake iOS app is third-party brand abuse. The only incident with even residual ambiguity is the unresolved April 2025 civil lawsuit alleging unencrypted browser memory storage, which Phantom has denied and no court has adjudicated. The page's own timeline and summary describe these facts accurately, yet the score of 47 places Phantom in WARNING alongside entities with elevated fraud or severe unresolved loss risk. Under the post-policy band semantics, CAUTIONARY (50–69) is the correct band for a legitimate operator with material-but-not-fraud-level caveats: one unresolved lawsuit, a patched critical vulnerability, and pervasive brand-abuse by third parties. A score of 63 reflects those caveats while properly distinguishing Phantom from entities that have caused losses through their own conduct.","score_delta":0,"sequence_num":8,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
