Avi Eisenberg convicted of $110 million Mango Markets heist

A jury found Avi Eisenberg guilty of fraud and market manipulation after he stole $110 million from the Mango Markets defi protocol in October 2022. Although he tried to argue that "code is law", and that his actions were legal as they were allowed by the project's smart contracts, jurors ultimately agreed with prosecutors that his manipulation of token prices constituted fraud.

Shortly after he was identified as the person behind the attack, Eisenberg tweeted that he "was involved with a team that operated a highly profitable trading strategy last week. I believe all of our actions were legal open market actions". Sadly for him, jurors didn't share this belief.

Eisenberg faces up to 20 years in prison.

$2 million emptied from Grand Base real world asset platform

Grand Base, a real world assets platform built on the Base layer-2 blockchain, has seen $2 million exit the platform in a hack or rug pull.

The team behind the project claimed that the deployer wallet had been compromised, allowing an attacker to drain the project's liquidity pool. Altogether, 615 ETH (~$2 million) was taken from the project.

Grand Base is a platform where users can trade "gAssets", which are crypto tokens that represent stocks in tech companies including Amazon, Apple, Google, Meta, and Microsoft.

$26 million liquidated in surprise Pac Finance smart contract change

Pac Finance, a fork of the Aave lending protocol deployed on the Blast blockchain, surprised some of its users as an unannounced and unexpected code change lowered the liquidation threshold. Pac Finance said that they had asked an engineer to make changes to the smart contract, and that that person had unexpectedly decreased the threshold at which positions could be forcibly liquidated. This change resulted in $26 million being liquidated across the project.

Pac Finance has said they are "actively developing a plan with [impacted users] to mitigate the issue."

Australian NGS Crypto mining fund collapses

NGS Crypto, which sold "crypto mining packages" to interested investors, has been put into receivership. The Australian firm encouraged customers to set up a self-managed super fund — a type of retirement fund — to achieve returns they said were powered by crypto mining. The firms advertised returns of up to 16% annually, and promised that investors would receive 100% of their initial investment back at the term's completion — even "in the unlikely event that crypto mining becomes unprofitable".

NGS and its associated business is believed to have pulled in around AU$62 million (US$42 million) from around 450 Australians.

Australian DCA Fund collapses with up to $65 million owed to creditors

Liquidators have been appointed for three cryptocurrency companies owned by Ash Balanian. DCA Capital, Digital Commodity Assets, and the Digital Commodity Assets Fund have all entered liquidation after investors raised red flags about the fund's management and licensure.

So far, losses are estimated to affect around 100 investors, who have up to AU$100 million (US$65 million) in claims.

Balanian had boasted of his career experience as a former NASA mission planner, and targeted his fund to wealthy investors with a minimum initial deposit of AU$50,000 (~US$33,000).

Crema Finance and Nirvana Finance hacker sentenced to three years imprisonment

Shakeeb Ahmed, the hacker who stole a combined $12 million from Crema Finance and Nirvana Finance in July 2022, has been sentenced to three years in prison. Ahmed had previously worked for Amazon, where he led a bug bounty program focused on paying whitehat hackers to discover flaws in Amazon's software.

US Attorney Damian Williams described this as the first ever conviction for a smart contract hack.

Ahmed forfeited around $12.3 million in stolen funds, and will pay more than $5 million in restitution.

MarginFi suffers huge outflows amid CEO ragequit

The MarginFi decentralized lending project on Solana has been at the epicenter of some major drama recently, amid concerns around oracle problems, withdrawal failures, and accusations that the project has not been paying out its promised rewards. Much of this came from a Solana staking pool, SolBlaze; MarginFi responded by describing their allegations as a "hit piece" and "misinformation".

On April 10, CEO Edgar Pavlovsky tweeted that he had resigned from MarginFi, publicly calling that he "d[idn't] agree with the way things have been done internally or externally". Pavlovsky had been criticized for his response to the controversy around MarginFi, in which he had been argumentative and insulting, tweeting things like "take your money out, go fuck yourself" to those who accused him and MarginFi of malfeasance.

Amid the chaos, more than $210 million in TVL has exited the protocol.

SEC sends Wells notice to Uniswap

The US Securities and Exchange Commission issued a warning to the Uniswap decentralized exchange in the form of a Wells notice. Wells notices are used to inform the recipient of an impending lawsuit, and give them a last-ditch opportunity to convince the SEC that the suit is unwarranted.

The notice was received with an adversarial posture by Uniswap, who announced its receipt with a blog post titled "Fighting for DeFi". "Taking into account the SEC's ongoing lawsuits against Coinbase and others as well as their complete unwillingness to provide clarity or a path to registration to those operating lawfully within the U.S., we can only conclude that this is the latest political effort to target even the best actors building technology on blockchains," they wrote.

The news was met with outrage in the crypto community, who generally saw the action as indicative of an overly aggressive posture by the SEC to crack down on defi and crypto more broadly.

$23 million goes missing amid STFIL claims that they're being investigated

STFIL, a protocol that promises liquid staking and "leverage mining" to holders of Filecoin's FIL token, announced on Twitter that "We believe that the STFIL core technical team is under investigation by local Chinese police."

According to STFIL, while some of the core team members were detained by Chinese police, FIL tokens were moved to an unknown wallet. They also acknowledged that there had been "abnormal, unscheduled upgrades to the protocol". They asked their community members for help in tracking the wallet.

Some speculated that the story was fake, and that the project had stolen the funds. However, Chinese police have in several instances cracked down on people and companies involved in Filecoin-related projects, including an $83.3 million alleged pyramid scheme in August 2023 and a group of Filecoin Ponzi schemers in 2021. Filecoin mining became popular in China after its 2018 initial coin offering, and also became a magnet for Ponzi schemes and other scams.

Bored Ape-themed fast food restaurant shuts down

It's hard to believe that the hamburger joint themed around the owner's Bored Ape NFT failed to take off. Although there was novelty value in the themed restaurant, which for a time boasted that it accepted cryptocurrency payments, the excitement seemed to wear off quickly after a few early news articles. After a while, the restaurant's crypto payments became spotty, with employees saying the system was unwieldy and unpopular among customers.

Some more recent Yelp reviews described fairly mediocre food, which "[t]he NFTs don't make up for".

The restaurant opened in April 2022, a month after owner Andy Nguyen purchased Bored Ape #6184 for $268,000, along with three Mutant Apes for an additional combined $187,000. #6184 became the restaurant's logo, and the others were incorporated into the restaurant's branding. The NFTs haven't been resold since, although it's unlikely they could recoup close to their original purchase prices — Bored Apes have been averaging a little under $50,000 in recent sales, and Mutants around $8,500 each.
