“I agree extra with the defence — you’ll be able to’t defraud somebody in the event you don’t mislead them or they don’t depend on your lies,” he mentioned.
Eisenberg’s scheme
Eisenberg was charged with market manipulation in December 2022 within the US District for the Southern District of New York after buying and selling with himself to inflate the worth of MNGO.
He then used MNGO perpetuals as collateral to borrow crypto price about $110 million from Mango Markets customers with “no intention of repaying them,” in response to prosecutors.
Eisenberg infamously claimed on social media that his actions amounted to a “extremely worthwhile buying and selling technique.” He used Mango Markets because it was designed, he mentioned, “even when the event staff didn’t absolutely anticipate all the implications.”
His legal professional, Brian Klein of Waymaker LLP, echoed the sentiment throughout closing arguments Wednesday.
Eisenberg efficiently pumped the value of MNGO, Klein conceded. However there was nothing improper with withdrawing crypto from Mango Markets in opposition to the inflated worth of MNGO perpetuals — that’s how the protocol was constructed.
Mango Markets “actually simply took an enter and used it,” Klein mentioned. “It was computerized.”
Furthermore, Mango Markets didn’t specify any phrases of service earlier than the exploit, Klein mentioned. The principles have been within the code, and everybody used the protocol at their very own danger.
Closing arguments
Of their closing argument Wednesday, prosecutors tried to forged doubt on the notion that Eisenberg ever thought his actions have been authorized.
Amongst different issues, Eisenberg fled to Israel the day he was outed by unbiased journalist Christopher Brunet. And pc data obtained by prosecutors present Eisenberg looking on-line for details about “felony and regulatory enforcement of market manipulation” and a “listing of Israel extraditions.”
Extra importantly, prosecutors mentioned, against the law is against the law — even when it occurs on a blockchain. Eisenberg illegally manipulated the value of MNGO, and successfully defrauded Mango Markets and its customers when he used MNGO’s inflated worth to empty the protocol.
“He needed to lie — he needed to trick the system to be able to take out the cash,” one of many prosecutors mentioned. “Simply because one thing is feasible, that doesn’t make it authorized.”
Code-is-law defence
The trial was among the many first to place crypto’s code-is-law ethos earlier than a decide and jury.
The idea is sacrosanct amongst some within the trade, who consider sensible contracts — the self-executing software program that powers blockchain-based functions — are fairer than the seemingly arbitrary and advert hoc rule-making in most conventional organisations.
Mikko Ohtamaa, CEO of DeFi buying and selling protocol Buying and selling Technique, took problem with prosecutors’ characterization of the exploit.
Mango Markets was simply exploitable, and its design — together with the strategy it used to find out the value of MNGO — was proper there within the protocol’s sensible contract.
Its customers “couldn’t have participated with out agreeing on this,” Ohtamaa mentioned.
In different phrases, they need to have identified one thing like this might occur, they usually assumed that danger once they used the protocol.
4 years in the past, customers of Compound, a lending-and-borrowing protocol on Ethereum, suffered the same exploit.
“No person was sued and everybody took their losses like a person,” Ohtamaa mentioned.
Flawed defendant
However Eisenberg was a flawed defendant: After the exploit, he tried to blackmail the cooperative that ruled the Mango Markets protocol, and he bought a Ukrainian lady’s FTX account to be able to conduct among the trades related to the exploit. Prosecutors additionally declare to have discovered youngster pornography on considered one of his cellphones.
“Avi was blackmailing, utilizing faux KYC and all different types of fraud, which make it harder to argue for him,” Ohtamaa mentioned, utilizing the acronym for know your buyer.
Shapiro mentioned some DeFi groups would possibly “embrace” the end result of the trial.
“It means they may have extra authorized treatments if it seems their code or danger parameters are defective,” he mentioned.
And he would possibly advise his personal shoppers to create phrases of service in mild of the decision.
“I believe there are issues DeFi groups can do to make clear what a sensible contract is and and isn’t, and placing that within the phrases of service could make sense,” he mentioned.
“One wonders what the outcome would’ve been if [Mango Markets] DID have a phrases of service and it made very clear there isn’t a counterparty to the transactions.”
Eisenberg faces as much as 10 years every for commodities fraud and commodities manipulation, and as much as 20 years for wire fraud. He shall be sentenced on July 29.
