Founder of DeFi platform Compound threatens users who received mistaken payments with the IRS

Robert Leshner, the founder of Compound Labs, took an unusual approach when trying to recoup funds that were mistakenly distributed through a $160 million bug in the protocol. He tweeted, "Please return [the funds]. Keep 10% as a white-hat. Otherwise, it's being reported as income to the IRS". The threats were not received particularly well, with some questioning what assumptions Leshner was making about his typical user's tax status, and Leshner subsequently apologized for his "bone-headed" tweet.

NFT collectors eagerly bought thousands of presales of an NFT project called "Iconics" after viewing sample artwork from a supposedly 17-year-old 3D artist. When they viewed their NFTs, instead of the 3D busts they had expected, they were brought to images of random collections of emojis. It was later discovered that the artwork had been stolen from an artist unaffiliated with the NFT project.

German government's blockchain-based ID wallet removed from app stores shortly after launch due to major issues

Shortly before the federal election, the German government launched the app "ID Wallet". It was supposed to store driver's licenses and other identification documents, and allow them to be shared with authorized parties (like the police, or during hotel check-ins). Because the distributed ledger back-end met neither basic EU security standards, nor handled more than a few thousand users (in total, not per second), the launch failed and private data stored in the app would have been exposed to identity theft. FOIA requests revealed that the project developers had known about the shortcomings of their design months in advance. The German Federal Office for Information Security wrote in a report, "[the use of the blockchain-based solution] significantly increases the complexity and, as a result, the fundamental susceptibility to security gaps in the entire system if the benefits are unclear".

Vee Finance platform emptied of $35 million a week after its launch

The Vee Finance decentralized finance platform was hacked for $35 million worth of Ethereum and Bitcoin. The platform suspended trading after the hack was discovered, and also tried to tempt the hackers with promises of a bug bounty if they'd just be so kind as to return the funds.

However, the team discovered the identity of the attacker and the funds were returned after some legal threats.

Head of Product for major NFT platform, OpenSea, is asked to resign following allegations of NFT insider trading

A Twitter sleuth discovers that OpenSea's Head of Product, Nate Chastain, had apparently been engaging in a form of insider trading by buying NFTs that he knew would later be featured on the front page of OpenSea, then selling them once their value increased from the spotlight. The Twitter user identified a chain of transactions show Chastain laundering the transactions through several anonymous accounts. OpenSea posted a statement confirming the shady trades had taken place, and that they had requested and received the employee's resignation, though they didn't specifically name Chastain as the culprit. Chastain's Twitter profile was updated shortly after, identifying him as a former OpenSea employee. OpenSea announced the next day that they had implemented policies preventing employees from trading on confidential information, which I guess they just hadn't bothered to think about previously.

They raised $18 million through the ICO, which they never registered with the SEC, to raise funds for the Rivetz blockchain security company. The funds, which were raised in ETH, were used to give the company's founder a $1 million bonus, plus a $2.5 million loan which he used to "purchase a house in the Cayman Islands that he then leased back to Rivetz Int'l."

El Salvador adopts Bitcoin as legal tender

Nayib BukeleEl Salvador's president Nayib Bukele (attribution)
Nayib Bukele unexpectedly announced that El Salvador would be adopting Bitcoin as legal tender, and the policy went into effect on September 7, 2021. With the benefit of hindsight, we can see that the decision came near the very top of the Bitcoin prices. Those who put money into Bitcoin at Bukele's urging have lost quite a lot of money.

So has El Salvador itself, assuming Bukele is telling the truth about his many claimed Bitcoin purchases. As of December 2022, Nayib Bukele has lost more than $67 million on those investments.

According to the DAO Maker team, 5,521 users were affected, and lost an average of $1,250 each. Attackers immediately moved some of the funds to the Tornado Cash cryptocurrency tumbler, while some remained dormant for months before being moved.

The "Fame Lady Squad" NFT project touted itself as a woman-designed and -developed project that would give back to women in the space, drawing support from high-profile individuals like Gary Vaynerchuk, and ultimately around $1.5 million in investments. Problem is, the three women who were supposedly running the project were a group of Russian men, accused by one of the individuals who uncovered the lie of trying to profit off American social causes. The group had a history of creating NFT projects based on false stories. One of their other projects, "Cyber City Girls Club", was intended to campaign to stop hate against Asians, and also originally purported to be run only by women (it wasn't).

The respondents agreed to a $12.8 million forfeiture of ill-gotten profits, plus a combined $250,000 penalty. The case marked a first from the SEC in the decentralized finance space.

DeviantArt releases software to detect infringement of artwork on NFT marketplaces... because the NFT marketplaces won't

DeviantArt releases software to automatically scan the NFT platform OpenSea for NFTs that use stolen artwork from DeviantArt. While it's awesome that DeviantArt created this tool to help the artists on their platform, it underscores the hands-off, look-the-other-way approach OpenSea has taken to the rampant art theft on their platform. Even reports of blatant copies of artwork have been rejected with no action, and artists are forced to report each infringement of their work individually even if there are many.

Uulala and related individuals settle with SEC for a total of $543,000 in fines

The company Uulala, which aimed to provide underbanked individuals with opportunities to build credit, settled with the SEC over charges that they ran an unregistered ICO that raised $9 million.

Norton Antivirus now sneakily installs a crypto miner on your computer so you can mine crypto (and give some to them)

Norton, the makers of the popular Norton Antivirus software, started installing "Norton Crypto" on customers' machines when they install the popular Norton 360 antivirus and malware protection software. It mines Ethereum, skimming 15% for Norton of course. They don't seem to mention that the energy costs incurred by crypto mining on a personal machine are likely to exceed any actual mining proceeds.

Coinbase said its USD Coin would be fully backed 1-1 with USD. It isn't.

Coinbase's USD Coin claimed that there was $1 "in a bank account" to back it, meaning that if everyone hypothetically tried to redeem their USDC at once at any given time, it would be possible. A July disclosure showed that this wasn't true, and that the coin was actually backed by commercial paper, corporate bonds, and other assets. Bloomberg speculated that the FTC might investigate the claim as a possible "unfair or deceptive act or practice".

An attempt to incorporate NFTs throws a wrench into a $40 million domain name auction

Frank Schilling, founder of the Uni Naming & Registry (UNR) held an auction for 23 TLDs (the bit at the end of the domain, like .com or .org). These included .link, .help, .game, and even .christmas. The April auction grossed more than $40 million, but as of mid-December the transactions had not been completed. This is because UNR attempted to add some marketing flair to the auction by including NFTs for each of the TLDs, to go to the auction winners. ICANN, the group responsible for much of the domain world, objected to and withheld consent for the transactions, writing "we sought to understand the impact of the transactions on the Domain Name System ('DNS'), including how Non-Fungible Tokens (NFTs) created on the Ethereum Name Service (ENS) were being used, and were involved in the transactions. ICANN repeatedly asked UNR for documentation or other information related to NFTs in the hopes that UNR would provide fulsome and complete responses."

German museum accidentally burns two valuable Cryptopunks NFTs in copy-paste error

A pixel art human wearing a purple baseball cap and smoking a cigaretteCryptopunk #2838 (attribution)
An employee of the ZKM Centre for Art and Media in Karlsruhe accidentally sent two of their four Cryptopunk NFTs back to its smart contract address. This is referred to as "burning" the NFTs, because the address is inaccessible and the NFTs are permanently impossible to trade as a result. The employee had copied the Cryptopunks contract address while browsing Etherscan, and didn't realize that was what he was pasting while making the transfer — wallet addresses are long hex strings like 0xb47e3cd​837ddf8e4c​57f05d70a​b865de6e​193bbb and are prone to errors like this since they are not easily distinguished at a glance. The two NFTs were originally acquired for the museum for approximately $100 each in 2017, and are individually valued at around $187,000 as of January 2022.

CEO of Turkish crypto exchange Thodex apparently makes off with $2 billion in investments

Turkish Bitcoin exchange Thodex halted trading and limited customers' access to their investments, claiming it was to investigate suspicious activity and swearing it was not an exit scam. With an international manhunt now underway for the Thodex CEO, and no sign of the approximately $2 billion that was invested in the platform, it seems awfully likely it was a rug pull.

$80 million taken from EasyFi lending platform

Hackers compromised a computer belonging to EasyFi founder Ankitt Gaur, accessing his private keys which allowed them to transfer $6 million in stablecoins and $120 million worth of EASY. The price of EASY crashed as a result of the low liquidity, limiting the hacker's total payout to around $80 million. EasyFi followed the breach with a hard fork to "EZ 2.0", and compensated users with a mix of stablecoins and "IOU tokens" that could later be redeemed for discounted EZ.

Africrypt investors disappear with $3.6 billion of investor funds

FTX loses $800 million to MobileCoin market manipulation

At some point in April 2021, a trader on the FTX cryptocurrency exchange successfully exploited the firm for around $800 million. They were able to take positions in relatively illiquid crypto tokens, including MobileCoin and BTMX, then manipulate the token prices to appear much higher than their true market value (for example, MobileCoin spiked to $70 a token, rather than around $6). Using these falsely high-valued tokens as collateral, the trader was able to borrow around $800 million in more liquid tokens, abandoning the relatively valueless collateral on the exchange.

During the October 2023 criminal trial of FTX founder and CEO Sam Bankman-Fried, he gave more detail on how the exploit took place, and admitted that he personally had disabled FTX's automatic liquidation systems for this account. Though he intended to closely monitor the account to prevent any losses to FTX, he said that it was actually his actions that allowed the trader to drain such a massive quantity of assets from the exchange.

Prosecutors alleged that Bankman-Fried later had his cryptocurrency trading firm, Alameda Research, shoulder the loss, saying that he'd hoped it would be less visible on Alameda's balance sheets than on FTX's.

Creators of "Turtledex", a project offering decentralized storage, make off with $2.5 million

24 hours after pre-sale, the team behind Turtledex drained $2.5 million from the liquidity pool and disappeared. Turtledex's smart contract had been audited shortly before the sale, with no major issues found, leading some to question the point of such audits.
