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

  1. 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.
  2. 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.
  3. 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.

Eisenberg, also known as 'Avi Eisenberg,' is a crypto trader who in October 2022 executed an oracle manipulation attack against Mango Markets, a Solana-based DeFi protocol, extracting approximately $110–117 million in digital assets. He publicly claimed the scheme was a 'highly profitable trading strategy' and a legal use of the protocol, returned approximately $67 million after a DAO-mediated settlement, and was subsequently charged by the DOJ, SEC, and CFTC. A federal jury convicted him in April 2024, but a federal judge vacated all criminal convictions in May 2025 on grounds of improper venue and insufficient evidence of material misrepresentation; prosecutors have appealed. Eisenberg is currently serving a separate 52-month federal prison sentence for possession of child sexual abuse material.","timeline":[{"date":"2022-10-11","event":"Eisenberg executes oracle manipulation attack on Mango Markets, draining approximately $110–117 million in digital assets by artificially inflating the MNGO token price by over 1,300% to use as collateral.","source":""},{"date":"2022-10-12","event":"Eisenberg publicly identifies himself on Twitter, describing his scheme as a 'highly profitable trading strategy' and asserting his actions were legal uses of the protocol.","source":""},{"date":"2022-10-15","event":"Mango DAO votes approximately 98% in favor of a settlement allowing Eisenberg to retain ~$47 million as a 'bug bounty' in exchange for returning the remainder and the DAO agreeing not to pursue criminal charges.","source":""},{"date":"2022-10-16","event":"Eisenberg transfers approximately $67 million in digital assets back to Mango Markets to recapitalize the protocol.","source":""},{"date":"2022-11-13","event":"On-chain analysts link the wallet 'ponzishorter.eth' to Eisenberg, alleging an attempted manipulation of Aave using CRV tokens via a large short position of approximately 92 million CRV.","source":""},{"date":"2022-11-22","event":"Eisenberg's alleged CRV short position on Aave is liquidated after the DeFi community rallies to pump CRV by over 40%; Aave sustains approximately $1.6–1.7 million in bad debt.","source":""},{"date":"2022-12-26","event":"FBI arrests Eisenberg in San Juan, Puerto Rico.","source":""},{"date":"2022-12-27","event":"Criminal complaint unsealed in SDNY charging Eisenberg with commodities fraud and commodities manipulation.","source":""},{"date":"2023-01-09","event":"CFTC files civil enforcement action against Eisenberg, the CFTC's first enforcement action for oracle manipulation on a decentralized exchange.","source":""},{"date":"2023-01-20","event":"SEC files civil charges against Eisenberg for manipulating the MNGO token, which the SEC characterizes as a security.","source":""},{"date":"2024-04-18","event":"Federal jury in SDNY convicts Eisenberg on three counts: commodities fraud, commodities market manipulation, and wire fraud, in what is reported as the first criminal conviction for DeFi market manipulation.","source":""},{"date":"2025-05-01","event":"Eisenberg sentenced to 52 months in federal prison after pleading guilty to possession of child sexual abuse material discovered during the Mango Markets investigation.","source":""},{"date":"2025-05-23","event":"U.S. District Judge Arun Subramanian issues 35-page opinion vacating all three criminal convictions on grounds of improper venue (transactions executed from Puerto Rico, not SDNY) and insufficient evidence of material misrepresentation for wire fraud.","source":""},{"date":"2025-05-24","event":"Government prosecutors announce appeal of the acquittal, arguing the judge applied an overly narrow reading of fraud law and ignored critical evidence.","source":""}]},"v":1}
