Polymarket partners with Chainalysis to deploy on-chain surveillance targeting insider trading and manipulation as volumes hit $7B monthly and regulation intensifies.

The European Central Bank maintained interest rates unchanged at its April 30 meeting, but ECB President Christine Lagarde’s press conference remarks indicated a June rate hike has moved closer to reality, according to ING analyst Carsten Brzeski. Lagarde stressed that risks on both growth and inflation are intensifying, though the decision to keep rates steady was unanimous.

Brzeski noted the ECB has introduced a clear inclination towards rate hikes within its wait-and-see stance. Markets currently price approximately 50 basis points of tightening by year-end, with between 20 and 40 basis points anticipated by June.

Inflation Risks Tilt Upward

The ECB baseline projections see headline inflation averaging 2.6% in 2026, 2.0% in 2027 and 2.1% in 2028, revised higher from December primarily due to energy price pressures from the Iran war. Core inflation is projected at 2.3% in 2026, moderating to 2.2% in 2027 and 2.1% in 2028.

Lagarde warned that “the war in the Middle East has made the outlook significantly more uncertain, creating upside risks for inflation and downside risks for economic growth”. The ECB president told the IMF’s International Monetary and Financial Committee that the conflict “will have a material impact on near-term inflation through higher energy prices”.

ECB staff projections included adverse scenarios showing headline inflation potentially reaching 3.5% or even 4.4% in 2026 if energy supply disruptions persist. The deposit facility rate remains at 2.00%, with main refinancing operations at 2.15% and marginal lending facility at 2.40%.

Over half of economists polled by Reuters expect the ECB to hold rates April 30 but hike in June as war-driven inflation accelerates. According to Bloomberg, the anticipated quarter-point increase would likely be the only move as the conflict won’t cause a long-lasting price shock.

Bitcoin’s (BTC) attempt to trade above $77,000 have failed multiple times over the past week, despite traders managing a one-day breakout to $79,500. Data show short-term holders taking profits as the rally peaked, sending 150,000 BTC to exchanges since April 15. 

Crypto analyst Darkfost noted the continued fragility among short-term holders (STHs), or wallets holding BTC for less than 155 days. As the price rose over the past two weeks, BTC transfers from these wallets to exchanges increased.

Three consecutive sessions saw 65,000 BTC, 54,600 BTC and 39,000 BTC sent to exchanges and these flows may have prevented Bitcoin from overtaking the resistance level at $80,000.

Spot volumes also declined sharply. BTC activity has dropped to levels last seen in September 2023, near the end of the previous bear phase. Binance recorded a monthly decline of about $25 billion in volume. Gate.io also saw a $13 billion drop, while OKX volumes fell by roughly $6 billion.

This indicates weaker investor conviction to build spot exposure at current price levels. Darkfost explained, 

“This contraction in volumes therefore reflects a temporary loss of interest in Bitcoin. While declining spot volumes can suggest negative short-term momentum, these phases of apathy are also often where new opportunities begin to emerge.”

Bitcoin needs fresh demand from leveraged traders

Bitcoin researcher Axel Adler Jr. highlighted a shift in liquidation pressure, with the seven-day oscillator turning positive and reaching +28.7 by April 30. Both the long and short positions have been squeezed more frequently, with total crypto liquidations reaching $604 million over the past 24 hours.

The shift supports the price in the near term. The 30-day average remains slightly negative, keeping the broader bias tied to prior long liquidations.

Open interest shows where traders’ urgency may be lacking. The seven-day average dropped to about 292,000 BTC from above 300,000 BTC. Around 8,000–9,000 BTC in leverage has been removed over the past 10 days, with daily changes still negative.

The price continues to press against $77,000, with no rise in participation. A stronger move higher would likely require open interest to increase and spot volumes to expand, signaling new capital entering the market rather than futures positions being forced to close.

The US Senate moved to bar members of Congress and their staff from participating in prediction markets, after a swift, unanimous vote to rewrite the chamber’s standing rules. The measure, approved by unanimous consent, immediately prohibits Senate officials from placing bets on markets that could hinge on information gained through their official duties.

Introduced by Republican Senator Bernie Moreno, the resolution frames the ban as a matter of public trust: “Engaging in any way in a prediction market or trying to place bets where we might have inside information deteriorates the confidence that our constituents have in us.” He added that “By changing the standing rules of the Senate, what we’re doing is allowing our constituents to know, once and for all, that no member of the United States Senate, no member of the staff of the United States Senate, can ever use that inside information as a way to monetize this job whatsoever.”

The decision comes as lawmakers weigh accusations of insider trading tied to public-affairs betting markets. In a related development, a special forces soldier connected to a plot to capture former Venezuelan President Nicolás Maduro was charged April 23 with using classified information to place bets on Polymarket; he has pleaded not guilty. soldier charged.

Senate Democratic leader Chuck Schumer underscored the moral dimension on the floor, saying that “of all the issues we debate in Washington, this falls clearly in the category of a ‘no-brainer.’” He warned that “We must never allow Congress to turn into a casino where members representing the public can gamble on wars, or economic crises, or elections.”

Republican Representative Ashley Hinson followed with a pledge to pursue a similar ban in the House, posting on X that she would introduce a comparable measure. posted on X.

Industry responses soon followed. Polymarket posted on X that it fully supported the Senate resolution and noted that its terms of service “already prohibit such conduct, but codifying this into law is a step forward for the industry.” Kalshi co-founder and CEO Tarek Mansour welcomed the development in a post on X, highlighting that Kalshi “already proactively blocks members of Congress and enforces against insider trading.” post.

For readers tracking the regulatory arc, Cointelegraph’s reporting has highlighted ongoing scrutiny of prediction markets and insider trading concerns. The current congressional move adds a formal, enforceable layer to the debate as lawmakers weigh the balance between free-market mechanisms and safeguarding public trust. Related coverage notes that industry players have faced renewed calls for stronger surveillance and governance frameworks.

Key takeaways

• The Senate unanimously approved a resolution changing its rules to ban members and staff from using prediction markets, effective immediately.
• The measure, introduced by Senator Bernie Moreno, frames the rule as vital to public trust and to prevent the monetization of inside information.
• The move follows concerns raised by recent cases, including a special forces soldier charged with using classified information to place bets on Polymarket; the defendant has pleaded not guilty.
• lawmakers signaled a broader push, with House Republicans indicating a similar ban could be pursued, signaling potential cross-chamber alignment on this issue.

Context and implications for the prediction-market ecosystem

Beyond the procedural shift, the resolution sits at the intersection of governance, insider-trading norms, and the evolving regulatory appetite toward prediction markets. The case involving a service member accused of leveraging classified information to bet on geopolitical outcomes has amplified concerns that some users could exploit public positions for financial gain. The Senate’s move effectively sets a floor for ethical conduct within federal offices and clarifies that participation in markets tied to policy outcomes will not be tolerated when sensitive information is at play.

Schumer’s remarks frame the issue as part of a broader stewardship challenge for Washington: the administration of credible, non-transparent gambling-like activity within institutions that wield real-world influence. His call to extend similar safeguards to the executive branch underscores a potential appetite for harmonized standards across government, a development that could influence how contractors, consultants, and civil servants engage with digital markets in the future.

From a market-structure perspective, the unanimous Senate action could reshape how participants approach political and macro-event bets. If other branches of government adopt comparable restrictions, prediction-market platforms may need to accelerate compliance tooling, enhance insider-trading detection, and tighten user vetting for public-sector users. Kalshi and Polymarket have already positioned themselves as enforcing stronger governance under existing terms of service; the newly codified rules could reduce the risk of regulatory backlash driven by perceived conflicts of interest.

Industry observers will also be watching the House’s response. If Ashley Hinson’s anticipated resolution gains traction, the United States could see a cross-chamber consensus on limiting official participation in prediction markets. This momentum could steer platform operators toward more transparent policies, stricter access controls, and more robust surveillance capabilities—aligning with broader efforts in the crypto and fintech sectors to separate governance from speculative activity tied to inside information.

Looking ahead, the practical questions center on enforcement mechanics and scope. How will the Senate translate the new rule into daily operations for staffers who rely on predictive tools for research and public-interest analysis? Will the House or administration push parallel standards, and how will platforms interpret and implement any new mandates without stifling legitimate hedging and research use? For investors and users, the development signals a continuing trend toward tighter governance in on-chain and off-chain prediction markets, with public trust as the decisive currency in the evolving regulatory landscape.

The next weeks will reveal whether Congress broadens the ban to the executive branch and how platforms adapt their compliance frameworks to meet any new statutory expectations. In the meantime, the core takeaway is clear: the line between informed governance and financial speculation is being drawn tighter, with Congress signaling that the integrity of official duties must remain insulated from market-based monetization.

Readers should watch for updates on whether the House formalizes a comparable prohibition, how platforms adjust their risk controls, and whether any new investigations or enforcement actions arise from the surge in interest around prediction-market governance. As the debate unfolds, the balance between innovation, user access, and public trust will remain at the heart of the discourse.

South Korean prosecutors have requested a 20-year prison sentence for the CEO of crypto deposit service Delio, calling the scale of alleged fraud against thousands of investors “massive.”

During closing arguments at the Seoul Southern District Court on Thursday, prosecutors asked the court to sentence Jeong Sang-ho under the Act on Aggravated Punishment of Specific Economic Crimes, citing what they described as deliberate deception and false promotion that left nearly 2,800 victims without access to their funds, according to the Korean news agency Yonhap.

“The defendant’s active deceptive acts and false promotion have resulted in numerous victims, and the scale of the damage is massive,” prosecutors reportedly said, adding that Jeong was “exacerbating their suffering by evading responsibility and maintaining an uncooperative attitude.”

Delio operated a crypto deposit service that promised investors high-interest returns on coins deposited for a fixed period. On June 14, 2023, the platform abruptly suspended withdrawals, freezing customer assets worth 250 billion Korean won ($169 million). A Seoul court declared the company bankrupt in November 2024.

Delio CEO acknowledges harm done to investors

Jeong’s legal team acknowledged the harm caused. “We are aware of the victim’s suffering and feel a deep sense of responsibility,” his attorney reportedly said, adding that Jeong would seek to compensate victims if acquitted.

Jeong was indicted in April 2025 on charges of embezzling $169 million in crypto assets from victims over roughly two years, between August 2021 and June 2023.

The first-instance verdict is scheduled for July 16.

South Korea launches crackdown on exchanges

The news comes amid South Korea’s launch of a regulatory crackdown on crypto exchanges. Earlier this month, the country fined Coinone, the country’s third-largest exchange, and ordered a partial business suspension over Anti-Money Laundering failures.

The action marks the second such crackdown in a few months, following a $24 million fine and six-month partial suspension handed to Bithumb in March for similar Anti-Money Laundering failures. The pressure on exchanges intensified after Bithumb mistakenly sent customers 620,000 Bitcoin, worth around $42 billion at the time, instead of 620,000 Korean won.

ECB held rates at April 30 meeting but Lagarde stressed rising inflation and growth risks from Iran war, signaling June hike possibility.

KelpDAO announced April 30 it has completed its committed contribution to the recovery fund, providing 2,000 ETH in treasury funds to the DeFi United recovery plan led by Aave, aimed at restoring peg support for rsETH and promoting the system’s return to normal operation. The funding represents a one-time investment intended to restore rsETH to its nominal exchange rate following the $292 million exploit that struck on April 18.

“As part of that commitment, we are contributing 2,000 ETH from our treasury directly to DeFi United,” KelpDAO stated. The protocol emphasized that its internal commitment before any public statement was that “rsETH holders will not be abandoned,” noting the contribution is a direct manifestation of that pledge.

Multi-Protocol Recovery Effort

DeFi United, in collaboration with multiple ecosystem participants including Mantle, Consensys, Arbitrum, Lido Finance, and LayerZero, has formulated a recovery path that includes re-capitalization of the bridging treasury, restoration of oracle functionality, and addressing funding gaps in affected markets. The coalition has tentatively raised more than $302 million to date, much of it from DAOs and crypto businesses within the ecosystem.

Major contributors include Consensys and Joseph Lubin with 30,000 ETH (approximately $69 million), Mantle with 30,000 ETH as a low-interest loan, Aave DAO with a pending vote for 25,000 ETH (approximately $57.5 million), and LayerZero with 10,000 ETH (approximately $23 million). The Arbitrum Security Council also froze 30,766 ETH (approximately $71 million) in attacker funds pending a governance vote.

The April 18 exploit drained 116,500 rsETH—worth about $290 million to $293 million—from KelpDAO’s LayerZero-powered bridge, representing roughly 18% of rsETH’s total supply. The attacker used the tokens as collateral across Aave, Compound v3, and Euler to borrow an estimated $236 million in ETH and WETH, leaving protocols with significant bad debt.

KelpDAO stated its investment helps accelerate the overall repair process, noting that as funds from various parties gradually come into place, collateral support for rsETH will gradually return to normal. The company committed to continue updating the community on progress as the recovery advances.

Syndicate Labs has confirmed that a leaked upgrade key let an attacker hijack its Commons cross-chain bridge, drain about 18.5 million SYND tokens worth roughly $330,000 plus user funds, and trigger a sharp price crash before the team pledged full compensation and sweeping security fixes.

Syndicate Labs has confirmed that a private key leak allowed an attacker to maliciously upgrade its cross-chain bridge contracts on two networks and siphon approximately 18.5 million SYND, worth about $330,000, alongside roughly $50,000 in user tokens. The team stressed that the incident was contained to specific chains and did not impact the broader Syndicate infrastructure.

In an official statement, Syndicate Labs said the breach followed “multi-stage reconnaissance, infrastructure mapping, and careful execution,” calling it an attack that “demonstrated a high level of technical complexity” while explicitly ruling out insider involvement. The attacker acquired around 18.5 million SYND and rapidly sold the tokens, with external security firms like CertiK tracing proceeds into Ethereum after bridging.

Root cause: weak key storage and upgrade controls

Syndicate Labs identified the root cause as poor operational security around the bridge upgrade keys, admitting that “the private key was stored in a password management tool without an additional layer of encryption.” The team also acknowledged that the upgrade process did not use multi-signature or hardware signatures and lacked “early warning and circuit breaker measures for contract upgrades,” leaving a single compromised key enough to push a malicious implementation.

Following the exploit, SYND’s price fell by more than 30% on some venues as the sell-off hit liquidity, echoing previous bridge hacks that sparked sharp token drawdowns. Similar cross-chain bridge incidents, such as earlier exploits on third-party infrastructure covered in this crypto.news story, have repeatedly underscored the dangers of centralized upgrade keys.

Syndicate Labs has pledged to “fully compensate all affected users,” including returning the 18.5 million SYND drained and providing “additional compensation,” while also “fully compensating affected application chain clients.” The company says it has sufficient reserves to cover losses, mirroring commitments seen in prior DeFi recovery efforts reported in another crypto.news story.

To prevent a repeat, Syndicate Labs has begun hardening its key management by strengthening private key encryption, tightening access controls, and planning to introduce hardware or multi-signature mechanisms alongside real-time monitoring of upgrade paths. The team’s roadmap follows broader industry calls for multisig-controlled bridges and automated circuit breakers, themes highlighted in a separate crypto.news story.

Syndicate’s SYND token remains under pressure as markets digest the attack and await concrete timelines for compensation and security upgrades.
