Someone steals the Bored Ape belonging to former NFL star Dez Bryant
The Bored Ape would likely fetch somewhere around $125,000 if resold. The other three NFTs would likely resell for somewhere around $8,700. Together with around $3,400 in stolen tokens, Bryant's total loss is around $139,000.
After some observers spotted the suspicious-looking transactions, Bryant confirmed on Twitter: "Yes my ape was stolen and I don't know how this is crazy".

Gemholic raises 921 ETH (~$1.7 million) in a token sale only to realize funds are stuck
.transfer()— a common function used with Ethereum projects that is not supported by zkSync.
The zkSync project evidently came to the rescue of Gemholic, announcing that they would change the protocol in a new release to add support for Solidity functions such as
.transfer(), which will ultimately free Gemoholic's locked funds.

Someone accidentally spends 100 ETH (~$190,000) on a free NFT
A trader apparently trying to bid $100 for one of the NFTs seems to have mistakenly entered 100 ETH, or around $190,000. The trade was of course quickly accepted by a seller who made a tidy 1666x the typical floor price.
Some have speculated the massive offer was money laundering, but the fact that the bid was an open offer that could be accepted by anyone seems to make that theory less likely.

Sentiment protocol hacked for almost $1 million
The attacker apparently took advantage of a re-entrancy vulnerability to execute the theft, then swapped the tokens and bridged them to the Ethereum main chain.
Sentiment tweeted that they were aware of the attack and investigating what had happened. They also stated that they were working with law enforcement. Later that evening, they sent a message to the hacker, offering to let them keep 10% of the stolen funds as a bounty if they returned the rest. Sentiment was audited by two crypto security firms.
On April 6, Sentiment announced that the exploiter had returned 90% of the funds, keeping $95,000 and receiving a promise from the organization that they would not try to prosecute the theft.
Paxful abruptly shuts down
Youssef was vague as to the reasons for the closure, writing that "While I cannot share the full story now, I can say that we unfortunately have had some key staff departures. Also, regulatory challenges for the industry continue to grow, especially in the peer-to-peer market and most heavily in the U.S."
Youssef later elaborated in a Twitter Space, explaining that he feared for the safety of user funds because of a lawsuit from his co-founder, who he also accused of "[driving] away all of our senior level staff".
Some had trouble withdrawing funds from the platform, though this seemed to be due to the overload. Youssef tweeted, "Paxful database is a bit overloaded now as everyone is withdrawing funds. It is making transfers slow. I promise funds r safe and they will clear soon".
On May 8, Paxful came back online, though it was unclear whether or in what capacity the business would continue to operate going forward.
Rumor tweet by crypto influencer causes BNB and Bitcoin sell-off
Cobie decided he wanted to make a record of his prediction, so he tweeted the SHA-256 hash of the string "Interpol Red Notice for CZ". Typically, this would allow him to later reveal the seed, allowing him to prove after the fact that he had indeed made a correct prediction. Why? I don't know. Bragging rights I guess?
Anyway, according to Cobie, one of Cobie's inner circle leaked the seed, and the contents of Cobie's prediction were widely circulated on Twitter. Some thought the prediction was inside knowledge of events that had already transpired. Someone else began circulating a doctored screenshot of the Interpol website, purporting to show a red notice. People began offloading their BNB tokens (the native token for Binance and Binance's blockchain), causing a sudden 3% dip in the token price. Bitcoin also fell on the news.
Over $25 million taken from an MEV bot by malicious validator
MEV bots are a phenomenon that became popular in recent times: bots that use various techniques to extract value by inspecting pending blockchain transactions and then sending advantageous transactions of their own. In this case, a bot was performing a "sandwich attack": sending transactions just before and just after a pending transaction, which manipulate the price of the underlying asset, allowing the bot operator to "steal" value from the victim — "steal" in quotes, because there is some debate over whether MEV bots are really stealing, or are operating within the rules laid out for them.
In order to manipulate prices in this way, they have to put a substantial amount of money at risk. A "rogue" Ethereum validator appeared to replace some of the transactions that were being executed by the bot, leading to a loss of WBTC, USDT, Dai, and WETH totaling a bit over $25 million.
