On-chain detective ZachXBT has put forward a reward of up to $10,000 for insider proof that Hong Kong-based market maker Heisenberg Guru (HSBG) manipulated trading on centralized exchanges. The bounty specifically targets activities near the RIVER token.

In a recent post through his investigative channel, ZachXBT accused HSBG of being involved in multiple market manipulation episodes on centralized platforms. He highlighted trading surrounding RIVER as an example of the alleged misconduct. The bounty aims to uncover hard documentation that can confirm or question ongoing suspicions about HSBG’s order book tactics.

ZachXBT named “Sion” and “Chao” as key figures within HSBG, shifting focus from a vague trading alias to specific individuals. He noted that a wide range of materials could qualify for rewards, including chat logs, contracts, and other internal communications that reveal how HSBG coordinates trading activity on centralized exchanges.

Whistleblowers are instructed to send tips via private message on X, where ZachXBT conducts most of his public investigations. He did not provide a detailed verification process initially, but his past work typically involves cross-referencing on-chain data, platform records, and corroborating statements before issuing comprehensive reports.

The incentive structure scales payments based on the quality, relevance, and verifiability of submissions, rather than offering a flat sum. This approach mirrors his previous crowdsourced probes, where independently confirmable documents receive higher compensation than anonymous claims.

This initiative underscores the expanding role of independent on-chain investigators in regulating ambiguous activities within crypto markets, especially for thinly traded CEX listings where formal oversight is often lacking. If the bounty yields credible evidence of manipulation tied to HSBG, it could force exchanges to reassess their partnerships with certain market makers and may prompt regulators to scrutinize trading practices in Hong Kong-linked market segments more closely.

Leopold Aschenbrenner, the former OpenAI researcher dismissed in 2024 over an alleged leak, has dramatically expanded his Situational Awareness fund. A recent SEC filing reveals that the fund’s disclosed equity holdings surged from $5.52 billion to $13.67 billion in the first quarter of 2026. The boldest bets are concentrated in a select group of Bitcoin miners including IREN, Core Scientific, Riot Platforms, CleanSpark, Bitfarms, Bitdeer, and Hive Digital. These positions reflect a conviction that energy infrastructure, not just algorithms, will become the most critical asset in the AI era.

Aschenbrenner’s thesis is straightforward: the bottleneck for AI progress is not semiconductor innovation but access to reliable power and land. Bitcoin miners already possess high-density power sites and grid connections that are scarce and difficult to reproduce quickly. His earlier white paper, “Situational Awareness: The Decade Ahead,” argued that compute infrastructure would dictate the speed of AGI development more than model breakthroughs. This logic is underpinned by market trends where miners like TeraWulf have seen AI and HPC hosting revenue outpace Bitcoin mining profits for the first time. Core Scientific is similarly converting its Pecos site into a massive 1.5GW AI data center campus, repurposing 300MW of existing mining capacity.

While placing large bets on miners, the fund simultaneously opened $7.46 billion in put options against chip giants. The largest single position is $2.04 billion against the VanEck Semiconductor ETF, followed by $1.57 billion against Nvidia, $1.07 billion against Oracle, and $1.01 billion against Broadcom. This dual strategy is internally consistent: if value accrues to power infrastructure rather than chipmakers, then semiconductor valuations could face pressure even as energy operators thrive. The broader industry shift is accelerating, with companies from Bitdeer to Riot converting mining facilities into AI data centers. Full holdings data is now publicly accessible through regulatory filings, confirming that crypto miners have become the foundation of one of the largest AI-focused investment strategies ever deployed.

Payward, the parent company of Kraken, reported $507 million in adjusted revenue for the first quarter of 2026, marking a 3% year-over-year increase. This growth came despite a challenging crypto market where Bitcoin dropped 22%, total market capitalization fell 23%, and industry spot volumes decreased 38%. The standout performer was derivatives trading, which saw daily average revenue trades jump 51% compared to the same period last year.

The surge in derivatives activity was fueled by the expansion of platforms such as NinjaTrader and Breakout, as well as Kraken’s broader build-out of its futures offerings. Management noted that this strategic focus helps offset the cyclical nature of spot trading. Adjusted EBITDA fell to $18 million for the quarter, as Payward intentionally increased spending on mergers and acquisitions, product development, and regulatory infrastructure. The company believes that investing during the current bear market will position it for stronger growth when market conditions improve.

Kraken’s spot market share rose from approximately 3.5% in mid-2025 to 5.2% in March 2026, a significant increase in a competitive landscape. The number of funded accounts grew 47% year-over-year to 6.1 million, while total client assets on the platform reached $40 billion. Co-CEO Arjun Sethi emphasized the company’s commitment to investing while others pull back, stating that this strategy validates their long-term approach. Payward’s ability to grow revenue and capture market share amid a downturn highlights the strength of its diversified revenue model, particularly from derivatives. If current trends continue, the company’s investments could yield substantial benefits when the next crypto upcycle arrives.

Kraken’s parent company, Payward, reported $507 million in adjusted revenue for the first quarter of 2026, marking a 3% increase compared to the same period in 2025. This growth occurred despite a 22% decline in Bitcoin’s price and a 38% drop in overall spot trading volumes across the industry. The exchange’s diversified business model, including a strong push into derivatives, helped offset the market slump.

Payward’s co-CEO, Arjun Sethi, emphasized the company’s proactive approach, stating that while others retreated, the firm continued to invest aggressively. The derivatives segment saw daily average revenue trades jump 51%, fueled by the recent acquisition of CFTC-licensed platform Bitnomial for $550 million, as well as growth in offerings like NinjaTrader and Breakout. Kraken’s spot market share also improved, rising from around 3.5% in mid-2025 to 5.2% in March 2026.

Total transaction volume on the platform reached $357 billion in Q1, while funded accounts grew 47% year-over-year to 6.1 million. Assets on the platform hit $40 billion. However, adjusted EBITDA fell to $18 million as Payward continued to spend on acquisitions, product development, and regulatory infrastructure. The company has been building a non-trading revenue stream, which accounted for 53% of total revenue in 2025, reducing reliance on volatile trading volumes.

On the IPO front, Payward confidentially filed a draft S-1 with the SEC in November 2025 but paused the process in March, with sources suggesting a public listing might be delayed until 2027. The exchange also laid off about 150 employees in May, citing AI-driven efficiencies, representing roughly 5% of its workforce.

On May 18, XRP retreated by 2%, settling near $1.3865 as investors cashed in gains after the token failed to breach the $1.42 resistance level. The most vigorous selling occurred during the May 17 23:00 UTC trading hour, where a surge of 144.3 million in volume drove the price from the $1.42 region down to around $1.378. However, buying interest emerged near $1.38, preventing a deeper decline and allowing for a partial recovery by the session’s end.

This rejection carries technical weight because a substantial number of XRP tokens, roughly 1.24 billion, are held by investors who purchased them between $1.45 and $1.47. This concentration forms a significant supply barrier that absorbs buying pressure each time the price approaches that threshold, as previously noted by crypto.news.

The token remains confined within a months-long symmetrical triangle pattern, which is now tightening toward an expected resolution in late May. While sellers maintain control at the $1.42 upper boundary, buyers have consistently defended the $1.38 support level. Analysts highlight that this compression is setting the stage for a decisive move, with the next major catalyst being the Senate Banking Committee’s vote on the CLARITY Act. According to Standard Chartered’s Geoffrey Kendrick, passage could drive $4 to $8 billion in additional inflows into XRP ETFs.

If the $1.38 support breaks, the next likely target is $1.30, as traders who entered at higher levels continue to sell on any bounce. Currently, XRP trades about 62% below its July 2025 all-time high of $3.65. Conversely, a close above $1.42 would be the first clear sign that sellers are losing their grip, potentially opening the door for further gains. Until then, the triangle compression is expected to persist, with analysts warning that the eventual breakout could be swift and sharp.

Citi has issued a warning about Bitcoin’s vulnerability to quantum computing, stating that the cryptocurrency faces an outsized threat compared to other digital assets. According to a research note from analyst Alex Saunders, dated May 18, the timeline for quantum machines to crack Bitcoin’s encryption is shrinking due to rapid technological advances. The report emphasizes that Bitcoin’s decentralized governance structure makes it particularly susceptible because protocol upgrades require extensive coordination among miners and node operators, a process that can take years.

The bank estimates that between 6.5 and 6.9 million Bitcoin, worth approximately $450 billion, have public keys already exposed on the blockchain. This includes wallets linked to the pseudonymous creator Satoshi Nakamoto. Such exposed keys could be vulnerable to a ‘harvest now, decrypt later’ strategy, where attackers collect encrypted data today for future quantum-enabled decryption. In contrast, proof-of-stake networks like Ethereum may be more agile in updating their protocols, though they present a larger attack surface overall.

Citi remains optimistic about the cryptocurrency’s long-term adaptability through post-quantum cryptography, but notes that proposed upgrades like BIP-360 and BIP-361 still require broad consensus. The broader Bitcoin ecosystem faces additional pressures from rising energy costs and the pivot of miners toward artificial intelligence, as highlighted by JPMorgan’s separate analysis on miner overvaluation. With Bitcoin trading near $76,900, the quantum threat adds another layer of strategic concern for investors.

Aave has reactivated borrowing for wrapped Ether (WETH) across multiple markets as the decentralized lending platform continues to address the aftermath of an exploit that occurred in April involving Kelp DAO. The move restores loan-to-value ratios for WETH collateral on Aave V3 Ethereum Core, Ethereum Prime, Arbitrum, Base, Mantle, and Linea, enabling users to borrow against WETH again and perform collateral or debt swaps.

According to Aave’s governance documents, the restrictions were put in place as emergency measures after attackers exploited Kelp DAO’s LayerZero-based bridge on April 18, using unbacked rsETH as collateral on Aave V3 to borrow large amounts of WETH. Following recovery efforts that progressed without additional user risk, governance participants approved the removal of the WETH freeze.

Earlier stages of recovery involved restoring backing for rsETH with recovered funds, reopening withdrawals, and coordinating token support from protocols participating in the DeFi United recovery initiative.

Meanwhile, legal and governance processes regarding frozen Ether tied to the exploit are still underway. A binding Arbitrum Improvement Proposal was opened for voting on May 15, seeking approval to transfer 30,765 ETH, worth about $71 million at the time, from the Arbitrum Security Council wallet to an address controlled by Aave LLC. Court filings indicated the funds were frozen on April 21 after investigators linked the assets to wallets associated with the exploit.

Before the governance vote, Judge Margaret Garnett of the Manhattan federal court modified an earlier restraining notice on May 9, allowing the transfer to proceed while protecting governance participants from personal liability. However, legal claims over the Ether remain active, with Gerstein Harrow LLP representing families seeking judgments against North Korea, arguing that the assets could be linked to the Lazarus Group. No court has formally determined this attribution as a legal fact.

Data from DefiLlama shows that Aave’s total value locked dropped by over $8 billion following the incident, with the protocol holding approximately $14.8 billion as of Monday, compared to nearly $23.5 billion in March. The exploit generated about $195 million in bad debt on Aave, as attackers stole around 116,500 Kelp DAO Restaked Ether tokens and used them to drain WETH liquidity.

Kelp DAO continues its recovery efforts separately, announcing plans to discontinue rsETH bridging support on Optimism, HyperEVM, Unichain, Avalanche, and MegaETH after June 15, as part of a network consolidation initiative focused on security. Users seeking to recover funds after the deadline will incur a 100 USDC fee per address. Earlier this month, the protocol also migrated rsETH to Chainlink’s oracle infrastructure, citing vulnerabilities in LayerZero’s cross-chain systems.

According to a recent analysis by NYDIG, the window for passing a comprehensive crypto market structure bill in the U.S. Senate is narrowing, and failure to act before the August recess could derail progress until after the midterm elections. Greg Cipolaro, head of research at NYDIG, emphasized in a market note that while the White House has expressed optimism about a July timeline, this target is more aspirational than realistic. The bill recently cleared the Senate Banking Committee along party lines, but with 53 Republican seats, at least seven Democratic votes are needed to reach the 60-vote threshold required to avoid a filibuster. Several Democrats have voiced concerns that the current version inadequately addresses illicit finance and sanctions evasion. The legislative calendar poses additional challenges: Congress is set to recess from late July to early September, and once campaigning for the November midterms intensifies, scheduling a bipartisan vote becomes politically risky. If the bill stalls before recess, the next viable opportunity would be a lame-duck session after the election. NYDIG notes that the outcome heavily depends on whether Republicans retain Senate control, as a Democratic majority in the next Congress would likely reduce the chances of advancing this Republican-backed proposal. The research firm underscores that passing the bill could significantly boost institutional confidence by formally designating Bitcoin as a commodity under CFTC jurisdiction, removing a key regulatory uncertainty. Conversely, failure to enact the legislation would leave the crypto industry mired in jurisdictional ambiguity. Unresolved disputes over decentralized finance enforcement, ethics provisions, or procedural delays could further hamper progress, Cipolaro warned.

The Verus-Ethereum bridge has been exploited for over $11.5 million after an attacker manipulated cross-chain message validation, according to several blockchain security firms. The incident was first flagged by Blockaid, which detected suspicious activity on the bridge late Sunday. The attacker’s wallet, identified as 0x5aBb…D5777, initially moved stolen funds to another address, 0x65C…C25F9.

PeckShield reported that the drained assets included 103.6 tBTC, 1,625 ETH, and nearly 147,000 USDC. The attacker later swapped these for 5,402 ETH, worth approximately $11.4 million. Prior to the exploit, the attacker’s wallet received 1 ETH via Tornado Cash, a common tactic to obscure transaction origins.

GoPlus Security noted that the attacker first sent a low-value transaction to the bridge contract before triggering a function that transferred reserve assets in batches to the drainer wallet. The firm suggested the exploit was likely due to cross-chain message validation failure, withdrawal logic bypass, or an access control weakness.

Blockaid compared the attack to the 2022 Nomad Bridge and Wormhole exploits, where fake transfer instructions tricked protocols into releasing funds. The security firm clarified that the issue was not an ECDSA bypass or notary key compromise, but a missing source-amount validation in the checkCCEValues function—a flaw fixable with about 10 lines of Solidity code.

ExVul reached a similar conclusion, stating the attacker used a forged cross-chain import payload that passed verification, triggering three transfers from bridge reserves. ExVul recommended tying transfer execution to authenticated payload data, stricter validation, layered verification, and emergency pause mechanisms for unusual outbound transfers.

Launched in 2023, the Verus-Ethereum bridge enables asset transfers between the Verus network and Ethereum. The Verus protocol, introduced in 2018, uses a hybrid proof-of-work and proof-of-stake model. As of publication, the Verus team had not commented on the exploit.

This breach adds to a growing list of DeFi attacks in 2026, with hackers stealing over $168.6 million from 34 protocols in Q1 alone. Major incidents include the $280 million Drift Protocol exploit and the $292 million Kelp exploit in April. Over the weekend, THORChain also suffered a $10 million exploit, highlighting ongoing vulnerabilities in cross-chain infrastructure.

Iran is reportedly working on a new insurance framework for vessels navigating the Strait of Hormuz, with rumors swirling about Bitcoin payments being part of the system. The Iranian Ministry of Economic Affairs has proposed a formal insurance scheme tied to marine transit and financial responsibility certificates, as reported by the state-linked Fars News Agency. According to Fars, the plan could bring in over $10 billion in revenue for Tehran by managing traffic through the strategic waterway.

This development comes amid ongoing U.S.-Iran tensions that have disrupted commercial shipping through the Strait, which normally handles about 20% of global oil trade. Multiple reports indicate vessel movement has slowed since U.S. airstrikes on Iran began in late February. At the center of speculation is a website called “Hormuz Safe,” which purportedly offered “Secure Digital Insurance for Maritime Cargo” and was linked to efforts to collect insurance payments in Bitcoin, though the site was inaccessible and no official confirmation exists.

Last month, Fars News denied earlier claims that Iran was already collecting transit tolls in cryptocurrency from ships passing through the Strait. In an April 23 report, the outlet called allegations of Iran accepting Bitcoin or stablecoins from vessels “inaccurate.” However, the Financial Times had earlier reported that Iran was considering a system where oil tankers would pay transit fees in crypto, with negotiations starting at around $1 per barrel. Bloomberg also reported that an intermediary tied to Iran’s Islamic Revolutionary Guard Corps had discussed similar pricing with maritime operators.

Risk advisory firm MARISKS warned that scammers are exploiting the uncertainty, sending fake messages to shipowners stranded west of the Strait, demanding Bitcoin or Tether for safe passage. The firm said these messages are fraudulent and do not originate from Iranian officials. It added that at least one vessel may have been fired upon after engaging with the scammers. Meanwhile, earlier media reports suggested Iran had already collected its first revenue from wartime shipping tolls last month, but those claims remain disputed.

Speculation around Bitcoin intensified after U.S. authorities froze $344 million in Tether USDt linked to Iran last month. Chainalysis noted that Iran has historically used dollar-backed stablecoins, especially USDT on the Tron blockchain, to move funds outside traditional financial systems. The blockchain analytics firm warned that any future crypto-linked toll structure in Hormuz could create compliance risks for virtual asset service providers interacting with sanctioned entities. Industry figures argue that Bitcoin may appeal more to sanctioned states because it lacks a centralized issuer that can freeze balances. In April, a spokesperson for Iran’s Oil, Gas and Petrochemical Products Exporters’ Union reportedly said ships could pass through the Strait by paying a tariff of $1 per barrel in Bitcoin, with transactions expected to settle within seconds to avoid tracing or confiscation.
