Here’s what happened in crypto today

Bitfinex and Tether have decided not to appeal the Freedom of Information Law (FOIL) request lodged by several news publications. Meanwhile, a court in Montenegro has approved the extradition of Terraform Labs co-founder Do Kwon to either South Korea or the United States, and Sam Bankman-Fried is trading Mackerel while jailed (yes, really). 

Bitfinex, Tether no longer opposed to FOIL request

Bitfinex and Tether have agreed not to oppose a Freedom of Information Law (FOIL) request initiated in New York by several high-profile news publications who accused the companies of exhibiting “certain behaviors.”

In a statement shared with Cointelegraph, the crypto exchange and stablecoin issuer said they were committed to sharing information in a transparent manner following a FOIL request earlier this year.

“It’s essential to clarify that transparency does not mean a wholesale release of all our documents,” the said. Both companies called for a “responsible document review” before any information is released publicly. 

The FOIL request stems from a February 2021 agreement between Bitfinex and Tether and New York regulators over allegations that the two companies commingled $850 million in client and corporate funds. As part of the agreement, the two companies reportedly paid $18.5 million in fines and agreed to submit quarterly attestation reports. 

Do Kwon extradition approved by Montenegro court

The saga of Terraform Labs co-founder Do Kwon continues to unfold, with a court in Montenegro approving his extradition to either South Korea or the United States.

The High Court of Podgorica has determined the legal requirements for Kwon’s extradition, according to an official statement posted on the court’s website on Nov. 24.

As the court approved Kwon’s extradition to either the U.S. or South Korea, the final decision on his extradition will be made by Montenegro’s minister of justice, the announcement notes.

Previously, a court in Montenegro sentenced Kwon to four months in jail after finding him guilty of using a forged passport to try to flee to Dubai via private jet. In June 2023, Kwon was reportedly charged with attempting to leave the country using a fake Costa Rican passport.

If the minister of justice allows the final extradition of the defendant, the extradition will occur after the execution of the criminal sanction announced before in the case of forged documents, the court statement notes.

Fish for fresh cuts: SBF trades mackerel while jailed

Sam Bankman-Fried’s crypto trading days are over, so the convicted founder has moved on to trading fish while behind bars.

The Wall Street Journal reported that Bankman-Fried traded four packets of Mackerel — “macks” in prison terms — for a haircut before his criminal trial last month.

Bankman-Fried doesn’t eat mackerel as part of his vegan diet — making them an easily traded commodity for the former Jane Street trader.

Mack packs have been the hottest trading commodity in prisons since the ban on tobacco products. The Metropolitan Detention Center commissary where Bankman-Fried is housed sells mackerel packets for $1.30.

Controversial tech figure Martin Shkreli, known as “pharma bro,” spent over four years in prison and confirmed macks were a staple currency in jail.

In a post on X (Twitter), Shkreli said paying four macks for a haircut was a “rip off” but noted it was still less than paying someone a book of stamps.

Bankman-Fried is sharing a cell at the Brooklyn prison with former Honduran President Juan Hernández and a former senior Mexican police officer, sources familiar with the matter told The WSJ.

KyberSwap hacker used “infinite money glitch” to steal funds

A decentralized finance expert has weighed in on the recent $46 million KyberSwap attack. 

Doug Colkitt, founder of the Ambient exchange, took to X (formerly Twitter) to explain how the attacker carried out “the most complex and carefully engineered smart contract exploit I’ve ever seen.” Based on Colkitt’s analysis, the attacker exploited an “infinite money glitch” and took advantage of KyberSwap’s unique liquidity implementation. That’s how they tricked the contract into believing it had more liquidity than it actually had, he said. 

The exploit “is specific to Kyber’s implementation of concentrated liquidity and probably will not work on other DEXs,” Colkitt explained. Based on his analysis, the exploit was carried out in multiple steps, beginning with the attacker borrowing 10,000 Wrapped Ether (wETH) from Aave. 

KyberSwap’s total value locked plunged by 68% shortly after the attack, reaching a low of around $27 million. Its TVL was as high as $134 million earlier in 2023.
