Cetus, a decentralized crypto exchange (DEX) built atop the Sui blockchain network, said $162 million of over $220 million stolen in a May 22 hack has been frozen.

According to the Cetus team, the DEX is working with the Sui Foundation and other entities within the ecosystem to recover the remainder of the funds. The Sui Foundation also confirmed:

"A large number of validators identified the addresses with the stolen funds and are ignoring transactions on those addresses until further notice. The Cetus team is exploring paths to recover those funds and return them to the community."

The Cetus hack is the latest in a string of such incidents impacting crypto and Web3 in the first half of 2025. Cybersecurity continues to be a major issue in crypto, with many industry executives calling for the sector to police itself and establish more robust defenses or risk increased regulatory scrutiny.

The Cetus hack: the story so far

On May 22, the Cetus DEX was hacked in what is believed to be a smart contract code exploit that saw the DEX drained of approximately $223 million in user funds.

OpenAI is planning to develop AI “companion” devices that will integrate artificial intelligence capabilities with everyday life, potentially opening the door to a new high-tech innovation used alongside laptops and smartphones.

In an interview with The Wall Street Journal, OpenAI CEO Sam Altman said he and designer Jony Ive are developing these secret devices for mass consumption, with plans to ship 100 million units upon launch.

Ives joined OpenAI after his startup, io, was acquired by Altman’s company in a $6.5 billion deal, the Journal reported on May 21. 

Neither Altman nor Ives specified what these companion devices would look like or how they would operate. Ives simply referred to them as a “new design movement” that would be similar to Apple’s family of hardware and software integrations. 

OpenAI has raised billions of dollars from investors, who view the company as a stalwart in the AI industry following the overwhelming success of its ChatGPT large language model (LLM). As of May, ChatGPT had nearly 800 million weekly active users, according to industry data. 

Key takeaways:

Solana’s bull flag pattern projects a rally to $260, but low spot buy volumes have analysts advising caution.

After briefly dropping to $160 from $184, Solana (SOL) is attempting to reclaim a position above its key resistance at $180 for a second consecutive week. With Bitcoin (BTC) hitting an all-time high, market speculators are banking on eventual capital rotation, which could pump major altcoins like SOL toward new highs.

Solana shows promising signs on the daily chart, forming a textbook bull flag pattern after a strong uptrend. While SOL prices currently trade under $180, a breakout above this level could propel SOL toward its first target at $200, with further upside potential to $220 if momentum sustains.

The trend remains bullish, supported by the relative strength index (RSI) at 64.30, indicating healthy momentum without overbought conditions. However, SOL needs a clear market structure break (MSB) or a decisive bullish breakout above $180 to trigger the next leg of the rally. 

Crypto exchange Kraken is planning to offer non-US customers the option of trading tokenized US stocks, part of the company’s push to offer more traditional assets via tokenization.

The products will be offered through Backed, a new Kraken partner, according to a statement shared with Cointelegraph. Tokens representing the stocks will be stored on the Solana blockchain due to its “unmatched performance, low latency and thriving global ecosystem,” the statement said.

“The whole point of crypto is that we're able to see things very transparently,” Kraken co-CEO Arjun Sethi said during Solana's Accelerate event on May 22. ”It's decentralized. It is open-source. You can innovate as quickly as possible, and there's no reason why companies like us can't morph to do that."

The decision to incorporate more traditional investment options may indicate a shift by Kraken to compete less with crypto-native exchanges like Coinbase and more with larger brokerages like Robinhood, which provide a wide range of investment options.

On April 14, Kraken opened access to exchange-traded funds and stock trading to US clients based in New Jersey, Connecticut, Wyoming, Oklahoma, Idaho, Iowa, Rhode Island, Kentucky, Alabama and the District of Columbia.

California Representative Maxine Waters, ranking member of the US House Financial Services Committee, has announced plans to introduce legislation “to block [Donald] Trump’s memecoin and stop his crypto corruption.”

In a May 22 notice, Waters said the Stop Trading, Retention, and Unfair Market Payoffs (TRUMP) in Crypto Act of 2025 bill would be aimed at blocking the US president, vice president, members of Congress and their families from engaging in “crypto crime.” The US lawmaker referred to Trump and his wife, Melania, issuing personal memecoins in January, his family launching a stablecoin, USD1, through the crypto platform World Liberty Financial, and the president attempting to establish a national Bitcoin (BTC) reserve as his sons back a BTC mining venture.

“Donald Trump is preparing to dine with the top donors of his memecoin who’ve made him, and his family, richer,” said Waters, adding:

Waters’ bill was one of many actions announced to oppose the president’s dinner to reward memecoin holders. Senators Chris Murphy and Elizabeth Warren are expected to attend a press event with representatives for the consumer advocacy group Public Citizen, and two Democratic organizations are set to protest at the Trump National Golf Club outside Washington, DC, where the memecoin dinner will be held.

Majority of participants have stayed anonymous ahead of dinner

The number and names of attendees to the May 22 dinner were still largely unknown, but several revealed their intentions through social media and news outlets to apply for background checks and meet the president. Bloomberg reported that more than half of the participants eligible for the dinner and “VIP Tour” — a separate experience limited to the top 25 memecoin holders — were likely foreign nationals.

Key points:

Mixed results for US jobless claims fail to dent risk-asset enthusiasm.

Despite concerns over the bond market, Bitcoin and stocks enjoy stability at the start of the Wall Street trading session.

BTC price expectations remain lofty amid low volatility and a curious lack of profit-taking.

Bitcoin (BTC) focused on $111,000 around the May 22 Wall Street open as record highs met mixed US unemployment data.

Key takeaways:

Bitcoin’s rally to new price highs happened as funding rates and trading sentiment remained unusually subdued.

Rising stablecoin supply and global M2 growth indicate untapped liquidity and the potential for further price increases.

Long-term holders are not aggressively selling, reflecting their expectation for continued Bitcoin price appreciation.

Bitcoin (BTC) hit a new all-time high on May 21, with prices rising to $111,860 on Binance on May 22, but the markets lack the state of frenzy associated with new highs. Economist and crypto commentator Alex Krüger noted that “this is the least euphoric new all-time highs” for Bitcoin, after highlighting subdued funding rates for Bitcoin across crypto exchanges.

DeLorean launched an onchain reservation system and non-fungible token (NFT) marketplace for its upcoming electric vehicle launch, introducing a new blockchain-based approach for reserving and reselling cars.

According to DeLorean, its Build Slot NFT collection grants holders priority access to purchase DeLorean’s upcoming electric car, Alpha 5 EV. The model is the carmaker’s first vehicle in over 40 years, inspired by the iconic flux capacitor from the movie Back to the Future.

The company created an exclusive marketplace for its NFT holders, in which users can buy or trade the NFTs using the USDC (USDC) stablecoin on the Sui network and will be able to earn rewards.

DeLorean says that each vehicle’s history and performance data will be recorded onchain through the FLUX protocol, including key data such as battery health, maintenance records, accident history, and verified odometer readings. 

This detailed data makes it easier for auto enthusiasts to bid on or resell vehicles in the secondary market, the company said.

Semiconductors scored a rare exemption from US President Donald Trump’s aggressive reciprocal tariffs, but the relief is symbolic at best. Most semiconductors enter the US embedded in servers, GPUs, laptops, and smartphones. 

The finished goods remain heavily tariffed, some with duties reaching up to 49%. The exemption looks good politically but delivers little practical benefit. Nvidia’s DGX systems, crucial for training advanced AI models, do not fall under the exempted HTS codes. Nvidia could pay effective tariffs nearing 40% on these vital components. Such costs threaten to stall critical AI infrastructure projects across the country. 

Semiconductor tariffs may compromise the goal of the CHIPS Act. The act promised tens of billions of dollars in subsidies to support domestic chip manufacturing. Yet advanced lithography machines — key equipment from countries like the Netherlands and Japan — face 20%–24% tariffs. Ironically, tariffs designed to boost American production increase the cost of essential manufacturing equipment.

The effect of new tariffs is already slowing progress in critical supply chains — just as generative AI and large language models are gaining momentum across sectors like finance and defense. Any delays or cost increases now could blunt America’s technological advantage.

As the question of stablecoin regulation heats up in the US Senate, so has the issue of which members are personally invested in cryptocurrencies and cryptocurrency firms.

On May 19, the Senate voted to invoke cloture and move ahead with the GENIUS Act, which would provide a regulatory framework for stablecoins. The measure passed 66-32, with 16 Democrats supporting the bill.

Democratic concerns over corruption and politicians’ ties to cryptocurrency firms made the bipartisan move controversial. After the vote was finished, Colorado Senator Michael Bennet introduced the STABLE GENIUS Act. The bill would prevent members of Congress from issuing or investing in digital currency and require them to put their crypto in a blind trust while in office.

Bills to prevent members of Congress from investing in companies they regulate have had little success. However, lawmakers are still required to disclose rough estimations of their, their spouse’s and their children’s investments. Here are 11 US senators who have invested in crypto firms.

Cryptocurrencies and non-fungible tokens (NFTs) can help investors protect their eroding purchasing power during an era of exponential currency debasement, according to analysts and industry leaders.

Investing in digital assets is becoming increasingly important in the “world of the exponential age and currency debasement,” according to Raoul Pal, founder and CEO of Global Macro Investor.

“You don’t own enough crypto. When you do, you don’t own enough NFT’s, as art is upstream of wealth. Both will never be this cheap again,” Pal said.

NFTs are “the single best long term store of wealth I know and you get to buy it before network effects kick in,” he added in another response.

“There is some validity to the statement that NFTs, and in extension art, become a vehicle for the wealthy once a certain level of wealth is reached,” wrote Nicolai Sondergaard, research analyst at Nansen, calling it a “natural move” for asset diversification.

What if a financial system could run itself not by burning electricity, but by rewarding good behavior? That’s the promise of staking, a mechanism that powers many modern blockchains by turning users into network operators. 

In this week’s episode of The Clear Crypto Podcast, hosts Gareth Jenkinson and Nathan Jeffay sit down with StarkWare’s Noam Nisan to unpack how this trustless engine works, why it matters and what’s really at stake.

Understanding staking

Jeffay began by highlighting how staking is part of the backbone that keeps the blockchain running, and runs itself, with volunteers.

“By doing this, they’re saying, OK, we’re taking this task of running the blockchain seriously. Here's some of our money. We're putting it down. We're showing that we're serious about doing this.”

To help unpack this topic further and examine the deeper mechanics behind staking, the hosts are joined by Noam Nisan, principal researcher at StarkWare and a widely respected computer scientist who has held roles at Google and Princeton.

The United Kingdom’s Court of Appeal partially dismissed a lawsuit brought by Bitcoin SV investors against major crypto exchanges, including Binance, for allegedly conspiring to delist the token in 2019.

In a judgment handed down on May 21, the court ruled that investors who held BSV through the delisting period (classified as “sub-class B”) were not entitled to billions in speculative damages based on BSV’s hypothetical growth.

These investors had claimed over 8.9 billion British pounds ($11.9 billion) in damages, asserting that Binance’s delisting deprived holders of the chance to profit from BSV’s potential rise to a “top-tier cryptocurrency” like Bitcoin (BTC) or Bitcoin Cash (BCH).

The court rejected this “foregone growth effect” theory, stating, “BSV was obviously not a unique cryptocurrency without reasonably similar substitutes,” pointing to the representative’s own use of Bitcoin and Bitcoin Cash as comparators.

Sub-class B’s central claim was that delisting led to a missed opportunity to benefit from price appreciation. However, the court determined that those investors had ample opportunity to mitigate losses by selling or reinvesting in other crypto assets.

Update (May 22, 2025, 1:27 pm UTC): This article has been updated to add further data and statements by Hacken.

Cetus, a decentralized exchange (DEX) built on the Sui blockchain, is suspected to have been hit by a massive exploit that may have drained more than $200 million worth of digital assets.

Pseudonymous Web3 researcher COMDARE3 posted on X that “users report” that Sui-based DEX Cetus is being exploited.” They also shared a screenshot of Cetus market data on DEX Screener, showing many assets losing well over half of their value over the last 24 hours.

The team behind Extractor, an onchain monitoring tool developed by crypto cybersecurity company Hacken, confirmed that “at least $63m was already bridged to Ethereum, 20k ETH was just transferred to a fresh wallet” in a single transaction. A Hacken representative told Cointelegraph that these findings were confirmed by the company’s Web3 researcher, Yehor Rudytsia.

Cetus pool data shows that as of the time of writing, the DEX processed $2.9 billion worth of transactions on May 22, a significant increase over the $320 million reported on May 21. This heightened level of activity may have been caused by funds being siphoned out of the protocol.

A crypto trader spent $3.8 million to buy Ether at a significantly higher price after selling the asset for almost the same amount about a month ago. 

On May 22, blockchain analytics firm Lookonchain reported that a crypto wallet spent $3.8 million to purchase 1,425 Ether (ETH) at $2,670 per coin, reentering ETH after a major rally. 

On April 13, the same wallet sold 2,522 ETH for $3.9 million, when the asset was trading at about $1,570, a decision that, in retrospect, looks poorly timed. 

“Think twice before selling your bags,” Lookonchain wrote, highlighting the potential gains if the trader just held on to their Ether instead of selling and repurchasing it at a higher price point.

Trader loses out on $2.67 million gain

With ETH up over 70% since the sale, the trader lost out on over 1,000 ETH, or roughly $2.67 million, in the process of buying back in. If the trader had decided to hold on to their Ether, the assets would be worth about $6.7 million. 

Crypto awareness in Singapore has reached an all-time high, with 94% of respondents in a recent survey indicating familiarity with at least one digital asset.

However, ownership declined, falling to 29% in 2025 from 40% the previous year, according to Independent Reserve’s fifth annual Singapore Crypto Market Survey released on May 21.

The survey, conducted in February with 1,500 participants, revealed that men remain more active in crypto investing than women, 35% compared to 24%.

Millennials and Gen X (aged 25–54) dominate the investor base, comprising 71% of all holders. Among those trading at least once a week, 76% fall into this age group.

The Federation Internationale de Football Association (FIFA) has selected Avalanche to power its dedicated blockchain network for non-fungible tokens and digital fan engagement, the organization announced on May 22.

FIFA’s layer-1 (L1) blockchain will be powered by the Avalanche network’s scalability-focused infrastructure for the association’s five billion fans worldwide.

The move comes nearly a month after FIFA announced its initial plans to launch a new network for its blockchain-based collectibles. AvaCloud’s Ethereum Virtual Machine (EVM) compatibility will enable smoother integration with decentralized wallets and applications.

The market cap of the world’s first cryptocurrency, Bitcoin, surpassed that of retail and tech behemoth Amazon on “Bitcoin Pizza Day.”

Market data shows that Bitcoin (BTC) had a market cap of $2.205 trillion at the time of writing, $70 billion more than the $2.135 trillion Amazon valuation.

“By surpassing Amazon in terms of capitalization, Bitcoin has attracted even more attention from the non-crypto audience,” said Alex Obchakevich, founder of Obchakevich Research.

Obchakevich said the latest rally “will strengthen confidence in Bitcoin and lead to new injections into the crypto market.” The surge came as Bitcoin set a new all-time high and traded above $110,000, which Obchavich said will “attract new investors to large funds.”

Obchakevich noted that institutional players continue to expand their role in the digital asset space:
