Avraham Eisenberg

• Self-described “digital art dealer”
• Mango Markets exploiter. Got arrested and charged with market manipulation offenses (28-12-2022).
• Has been accused of multiple shady dealings (13-10-2022):

"An article accusing Avraham Eisenberg contains screenshots of a Discord conversation in which the account AvrahamEisenberg#5451 discusses the details of the attack, days before it takes place. He’s also shown to have claimed the blockchain address ponzishorter which funded the attack as his own, back in June.

When prompted by another user to disclose the vulnerability, he rejects the idea based on the assumption that the project’s treasury is too small to pay out a generous bug bounty. In fact, following the attack, the hacker used freshly stolen funds to create and vote on a governance proposal that would reward them with a bounty of over half the hacked amount. Eisenberg’s response to the screenshots, also published in the same article claims he’d been “exploring a number of lending platforms with exposure to low-cap coins,” but doesn’t mention Mango Markets specifically.

An address linked to the ponzishorter account was used in a manipulation of lending protocol Fuse’s liquidation mechanism in April.

And in February, he was accused of embezzling $14 million from Fortress DAO, a project for which he was lead developer. Allegedly, Eisenberg abused the project’s treasury redemption mechanism, meant to redistribute remaining funds to token holders as the DAO closed down operations.

However, he’s not always successful as Kleros founder Clément Lesaege made clear while describing his attempts to exploit the “decentralized arbitration protocol,” via its claims process.

Not content with only blockchain-based disputes, Eisenberg even sued a small town in New York State after falling on ice.

Addressing the comments from Lesaege, Eisenberg, claims:

“In February, Fortress DAO voted for a full redemption of the Treasury and I helped implement that. By the end of March, this redemption was complete and any fort token holders were able to exit for a proportional share of the Treasury.

“Clement Lesaege, ran a 51% attack on his own protocol. He had put millions of dollars into the Unslashed insurance pool, and then when claims were made, he used his substantial PNK holdings to deny millions of dollars of legitimate insurance claims to line his own pocket. I documented this fraud extensively at my Deep Fi Value blog in a post titled, The Kleros Experiment Has Failed.”"
