Solana was so overloaded with bot transactions that users couldn't transact. As the cryptocurrency market in general continued to tank, users rushed to top up the collateral they had provided to keep their loans from being liquidated and found they couldn't get the transfers to go through. One user reported spending eight hours trying unsuccessfully to add collateral, before eventually getting liquidated and losing 500 SOL (about $47,500). It took Solana 24 hours to even identify the cause of the issue, and another 24 before they were able to resolve it. Traders watching their loans get liquidated were not impressed when Solana Labs co-founder tweeted "lol", with a screenshot of a Solana node showing high amounts of duplicate packets.
Ozzy Osbourne's NFT project, CryptoBatz, changed to a slightly different Discord URL ("cryptobatz" rather than "cryptobatznft") some time after the new year. However, they forgot to take down at least one tweet mentioning the previous URL, and scammers were able to set up a new server at that location. Users were instructed to "verify", which redirected them to a phishing site where the contents of their wallets were stolen.
Shortly after rolling out their hexagonal NFT profile pictures, @twitter posted "gm, looking for an nft pfp". The next day, McDonald's German language communications account, @McDonaldsDENews, replied "Say no more!" with attached pixel art of the Twitter bird logo holding a McDonald's bag in its beak. After further investigation, the art was found to be nearly identical to an image from a tweet by @SarahBurssty, which ironically was created to criticize Twitter's support of NFTs.
Security researchers publicly disclosed a critical privacy vulnerability with the popular cryptocurrency wallet Metamask, where a malicious attacker can easily create an NFT and airdrop it to a victim to obtain their IP address (and thus potentially their location). Metamask founder Dan Finlay acknowledged that "this issue has been widely known for a long time", and that the researchers were "right to call us out for not addressing it sooner. Starting work on it now. Thanks for the kick in the pants, and sorry we needed it."
Although NFTs-as-profile-pictures on Twitter is nothing new, Twitter launched a new feature in which users can connect their crypto wallets to verify that an NFT belongs to them. Such verified NFTs will display with a hexagon shape, rather than the standard circle, presumably to differentiate these users from the right-clickers.
Popular NFT marketplace OpenSea suffered an outage that had ripple effects throughout several major services using their APIs, including the browser extension crypto wallet MetaMask. The same day, Twitter announced it was rolling out its support for NFT profile pictures, an announcement that was dampened a bit by collection pages failing to load due to the outage. The widespread effects of the outage highlighted points by many web3 critics, that the ecosystem is hardly as decentralized in practice as it claims to be.
Kingfund Finance suddenly drained more than 300 WBNB (about $141,000) from their project. This happened a few days after users began to report being blocked by the project's Twitter account and kicked from its Telegram channel for reporting issues with unavailable funds, apparently an attempt to buy time as they prepared for their exit. Around the time of the rug pull, they took their Twitter and website offline.
Multichain publicly announced a vulnerability that was affecting their tokens, without first notifying users to ask them to remove vulnerable funds. Several hackers quickly exploited the vulnerability, stealing around $3 million from the platform. Security researchers described the saga as "the worst way to treat a vulnerability".
Apparently the real issue with crypto grifts all along has been that it's just too dang hard to put your money into them. Mastercard has shown up to fix that, announcing a new partnership with Coinbase to allow Mastercard holders to buy NFTs on Coinbase's upcoming NFT platform with credit. With just a jaw-dropping attempt at spin, Mastercard wrote in their announcement tweet, "We're working to make NFTs more accessible because we believe tech should be inclusive."
The BNB Heroes play-to-earn game apparently rug pulled after a period of inactivity from the development team. The developer drained almost $200,000 from the token pool, plummeting the token value by 65%.
