21Shares Introduces JitoSOL ETP to Offer Staking Rewards via Solana

TLDR:

  • Austin Hill told Epstein that Ripple and Stellar were “bad for the ecosystem” Blockstream was building.
  • Blockstream co-founders demanded Epstein reduce his allocation due to competing protocol investments.
  • Joi Ito and Reid Hoffman were copied on the 2014 email discussing strategic investor alignment issues.
  • Gary Gensler taught crypto at MIT while Ito facilitated Epstein donations to the same institution.

 

Newly surfaced correspondence from 2014 shows Jeffrey Epstein held an investment allocation in Blockstream, a Bitcoin infrastructure company.

The email from CEO Austin Hill to Epstein reveals strategic pressure to divest from competing protocols Ripple and Stellar.

The communication, which included MIT Media Lab Director Joi Ito and investor Reid Hoffman, demonstrates active enforcement of ecosystem loyalty among early cryptocurrency investors.

Strategic Investor Conflicts in Early Blockchain Development

Austin Hill’s July 31, 2014 email to Epstein outlined a direct request from Blockstream’s co-founders. According to the original message, Hill stated he had “been asked by the other cofounders to reduce or take your allocation away.

The CEO explained that Ripple and Jed McCaleb’s new Stellar “are bad for the ecosystem we are building.” Hill further noted that having investors “backing two horses in the same race” would damage the company’s strategic positioning.

The correspondence treated Epstein as a strategic investor whose portfolio choices affected Blockstream’s governance and capital strategy.

These were not incidental social exchanges but direct operational communications about investment policy. The email exchange occurred during a critical period for blockchain technology development when competing visions for distributed ledger architecture were taking shape.

Blockstream positioned itself around Bitcoin and the Lightning Network infrastructure. Meanwhile, Ripple’s XRP Ledger and Stellar represented alternative approaches to distributed ledger technology.

These competing protocols created tensions among investors and developers about which system would become the dominant base layer for cryptocurrency transactions.

The involvement of Joi Ito added another dimension to these networks. As MIT Media Lab Director from 2011 to 2019, Ito served on multiple technology boards and advised governments on digital policy.

His presence in the email chain demonstrated connections between cryptocurrency investment decisions and academic institutions researching blockchain technology.

MIT Connections and Regulatory Developments

Ito’s role at MIT Media Lab positioned him as a bridge between cryptocurrency investors and academic research. The lab expanded corporate funding under his leadership while focusing on AI, digital identity, and cryptocurrency projects.

Epstein’s ties to MIT later became controversial when 2019 reporting revealed the Media Lab had accepted donations linked to him. Ito resigned after admitting errors in judgment regarding these financial relationships.

Gary Gensler taught cryptocurrency courses at MIT before his 2021 appointment as SEC Chairman under President Biden.

His academic work occurred within the same institutional environment where Ito facilitated donor relationships. The regulatory approach toward Ripple and other cryptocurrency projects would later become a defining feature of Gensler’s SEC tenure.

Rob Cunningham’s analysis on KUWL.show examined these overlapping relationships. His post noted that “Epstein functioned as a capital node in overlapping elite tech networks.”

The connections between Blockstream, MIT, and later regulatory actions suggest coordinated efforts to shape cryptocurrency market development according to specific ecosystem preferences.

The 2014 correspondence reveals that ecosystem competition extended beyond technical differences. Investor alignment and narrative control played substantial roles in early blockchain development.

Bitcoin infrastructure companies viewed alternative protocols as existential threats to their position as the primary decentralized rail for digital assets.

Iran’s Best War Tactic is Now a Liability at the Negotiating Table

Iran’s Best War Tactic is Now a Liability at the Negotiating Table

The mines Iran scattered across the Strait of Hormuz are now preventing the country from widening access to the waterway, as Tehran cannot account for where all of them ended up, US officials say.

The revelation comes as senior delegations from both countries are set to meet in Islamabad for negotiations that will test whether any truce can survive.

Iran Can’t Find the Mines It Planted in the Strait of Hormuz

According to The New York Times, Iran used small boats to scatter mines across the strait after the US and Israel launched their strikes on February 28. US officials noted many mines may have been placed without recorded coordinates or in ways that allowed them to drift.

The haphazard placement created a problem Tehran did not anticipate. Foreign Minister Abbas Araghchi signaled that Tehran would allow vessels through the waterway, but “with due consideration of technical limitations.” American officials said that phrase referred directly to Iran’s inability to find or clear its own ordnance.

Meanwhile, this directly undermines the toll system Iran announced. Under that framework, laden tankers must email cargo details to Iranian authorities and then pay $1 per barrel of oil in Bitcoin within seconds. The system was designed to bypass sanctions.

The Hormuz Letter highlighted that, at pre-war traffic of roughly 20 million barrels per day. This fee structure could generate approximately $7.3 billion annually. However, with uncharted mines still drifting through the strait, the toll’s revenue potential is largely theoretical for now.

US-Iran Ceasefire Talks Open Under Immense Pressure

Senior delegations from both countries have arrived in Islamabad for ceasefire talks. Vice President JD Vance leads the US team alongside Steve Witkoff and Jared Kushner. Meanwhile, Parliament Speaker Mohammad Bagher Ghalibaf and Araghchi head Iran’s delegation.

President Trump has demanded the “complete, immediate, and safe opening” of the strait as a condition for the ceasefire to hold. Yet neither side possesses mine-clearing capabilities. 

“The US military lacks robust mine removal capabilities, relying on littoral combat ships equipped with mine sweeping capabilities. Iran also does not have the capability of quickly removing mines, even the ones it planted,” the report read.

The mine problem feeds into a broader economic fallout. BeInCrypto recently highlighted that the Strait’s closure has also disrupted global fertilizer and aluminum supply chains, amplifying the damage well beyond oil prices.

Whether Islamabad produces a framework for sustained mine clearance and verified strait reopening will determine whether the ceasefire survives beyond its April 22 expiration.

CFTC Wins Arizona TRO as Prediction Markets Criminal Case Pauses

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

TLDR:

  • Arizona must pause criminal charges against CFTC-regulated prediction markets after the federal TRO order.
  • The CFTC says federal law grants exclusive authority over event contracts and market enforcement.
  • Connecticut and Illinois now face similar federal lawsuits over state prediction market restrictions.
  • The ruling strengthens legal momentum for federally supervised crypto-linked trading platforms.

A federal judge in Arizona temporarily halted the state’s criminal case against federally regulated prediction markets on Friday. The order came after the Commodity Futures Trading Commission asked the court to stop Arizona’s enforcement push. 

The ruling preserves the status quo while a broader federal preemption fight moves forward. It also sharpens the legal divide between state gambling rules and federal event contract oversight.

CFTC Arizona TRO Freezes State Prediction Markets Charges

The U.S. District Court for the District of Arizona granted the temporary restraining order on April 10. The court barred Arizona from continuing criminal proceedings against CFTC-regulated designated contract markets.

According to the CFTC filing, the agency moved earlier this week for emergency relief. That motion followed its original complaint seeking to block Arizona from enforcing state law.

The dispute centers on whether federal law preempts state gambling and criminal statutes. The CFTC argues the Commodity Exchange Act gives it exclusive authority over event contracts.

Chairman Michael S. Selig said the order keeps the legal status quo intact while the court reviews jurisdictional questions. The agency also tied the case to broader concerns around state interference in federally supervised markets.

Arizona became the first state to pursue criminal counts tied to prediction market listings, including contracts offered by Kalshi. The restraining order now pauses that path, at least temporarily.

Federal Prediction Markets Fight Expands Beyond Arizona

The Arizona action forms part of a wider CFTC legal campaign. Last week, the agency filed related complaints against Connecticut and Illinois.

Those cases seek declaratory judgments confirming exclusive federal control over event contracts. The CFTC also wants permanent injunctions blocking states from enforcing overlapping laws.

The timing matters for crypto-linked prediction markets as well. Platforms like Polymarket and Kalshi increasingly overlap with digital asset users, stablecoin settlement, and onchain market infrastructure.

Recent court decisions have already strengthened the federal side. Earlier this week, an appeals court blocked New Jersey from shutting down Kalshi’s sports markets.

Friday’s Arizona TRO adds another legal marker in the same direction. For traders and exchanges, the immediate effect is procedural, but the broader question remains federal control over fast-growing prediction markets.

Stablecoin Flows Emerge as Leading Signal for L1 Market Performance: Research

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

TLDR:

  • Artemis stablecoin factor posted 83.6% annualized returns with minimal dependence on Bitcoin direction.
  • The strategy gained 6.8% monthly across BTC down months, showing resilience during crypto market weakness.
  • Mid-cap chains including Polygon and Sei generated 84% of total stablecoin factor returns over five years.
  • Stablecoin flows remained Artemis’ least-correlated alpha factor with only 6.1% variance overlap.

Stablecoin flows are emerging as one of crypto’s clearest signals for layer-1 market rotation. 

New research from Artemis shows capital moving through stablecoins consistently preceded stronger relative returns across major chains. The firm’s five-year backtest found the strategy remained largely detached from broad crypto market direction. 

Results also showed the factor produced gains during months when Bitcoin posted losses.

Stablecoin Flows Predict L1 Returns Across Market Cycles

Artemis said its weekly rebalanced long-short factor generated a 1.67 Sharpe ratio over five years. The model delivered an annualized return of 83.6% during the test period.

The same backtest recorded a maximum drawdown of 43.9%. A volatility-targeted overlay lowered drawdown to 31.9% while reducing Sharpe to 1.17.

The data pointed to minimal dependence on Bitcoin’s broader trend. Artemis reported a market beta of -0.03 and an R² of 0.1%.

That structure became more visible during weaker crypto conditions. Across 30 BTC-negative months, the factor returned 6.8% monthly while Bitcoin fell 10.9%.

Artemis also measured annualized alpha at 73.8% after controlling for market exposure. The reported t-statistic reached 3.31 with significance at the 1% level.

The firm noted the strategy’s out-of-sample Sharpe estimate still held at 0.96 after applying a degrees-of-freedom haircut. That kept stablecoin flows among its strongest market-neutral crypto signals.

Mid-Cap Chains Drive Stablecoin Factor Alpha

Most of the gains came from the long side of the book. Artemis said 84% of returns originated from long exposure to chains attracting positive stablecoin inflows.

Mid-cap networks dominated the return profile. Polygon, Mantle, Optimism, BSC, and Sei contributed 84% of total factor returns.

The research also showed limited overlap with Artemis’ broader factor suite. Maximum pairwise correlation across the stack measured only 0.16.

Even after spanning regression against all other factors, the stablecoin signal retained a 2.54 t-statistic. Artemis said just 6.1% of variance overlapped with other models.

Performance also stayed resilient through distinct market phases. The factor returned 262% in 2021, 47% in 2022, and 315% in 2025.

Its only negative year came in 2024 with a 13% decline. Artemis linked that period to stagnant aggregate stablecoin supply growth before recovery resumed.

EngageLab Flaw Opened 30M Wallet Apps to Android Data Theft: Microsoft

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

TLDR:

  • Microsoft found the EngageLab SDK bug could expose private wallet data across 30M Android installs globally.
  • The flaw abused Android intents to grant hostile apps persistent read and write provider permissions.
  • EngageLab fixed the issue in v5.2.1 by changing MTCommonActivity to non-exported status.
  • Google Play removed affected wallet apps, while Android added safeguards for already installed versions.

Microsoft has disclosed a severe Android SDK vulnerability that placed more than 30 million crypto wallet installs at risk. The flaw affected EngageLab’s widely used EngageSDK, which many wallet apps used for push messaging features. 

According to Microsoft’s security research, the issue enabled malicious apps on the same device to bypass sandbox protections. Google Play has since removed all identified apps using the vulnerable SDK versions.

EngageLab Android SDK Flaw Exposed Crypto Wallet Attack Surface

Microsoft said the issue centered on an exported Android activity called MTCommonActivity

The component was automatically added during manifest merging after developers imported the SDK. Because it appeared post-build, many teams likely missed it during review. That left production APKs open to hidden risk.

The vulnerable flow began when the activity received an external intent. Its onCreate() and onNewIntent() callbacks both routed data into processIntent()

That method extracted a URI string and forwarded it deeper into the SDK logic. The chain eventually rebuilt and launched a new intent.

Microsoft’s write-up noted the critical failure happened in a helper method. Instead of returning a safe implicit intent, it returned an explicitly targeted one. That changed Android’s normal resolution path and let hostile apps redirect execution. 

In practice, the vulnerable wallet app launched the malicious payload with its own privileges.

The risk worsened because the SDK used Android’s URI_ALLOW_UNSAFE flag. That allowed persistent read and write URI permissions inside the redirected intent.

A malicious app could then gain access to non-exported content providers. From there, sensitive wallet files, credentials, and user data became reachable.

Microsoft Patch Timeline and Android Wallet Mitigation Guidance

Microsoft Security Vulnerability Research first identified the flaw in EngageSDK version 4.5.4 in April 2025. It then notified EngageLab under coordinated disclosure rules. 

The Android Security Team also received the report because affected apps were live on Google Play. The fix arrived months later in version 5.2.1 on November 3, 2025.

In the patched release, EngageLab changed the vulnerable activity to non-exported. That single change blocks outside apps from invoking the component directly. Microsoft said it currently has no evidence of in-the-wild exploitation. Still, it urged developers to update immediately.

The report stressed that third-party SDKs can silently expand wallet attack surfaces. 

Crypto apps face elevated stakes because they often store keys, credentials, and financial identifiers. Even minor upstream library flaws can ripple across millions of devices. This case pushed total exposure above 50 million installs when non-wallet apps were included.

Microsoft also said Android added automatic protections for previously installed vulnerable apps. Those mitigations reduce risk while developers migrate to the fixed SDK. 

The company urged teams to inspect merged manifests after every dependency update. That review can catch exported components before release.

XRP Price Flashes Multiple Bottom Signals As Bulls Defend $1.30.

XRP Price Flashes Multiple Bottom Signals As Bulls Defend $1.30.

XRP (XRP) has been in an eight-month downtrend, with momentum and onchain indicators at levels that previously coincided with macro bottoms.

Data from TradingView reveals that the relative strength index (RSI) of the XRP/BTC ratio is at 24, the most oversold level since October 2025. 

Such low levels in the daily RSI have marked market bottoms for the ratio, ultimately leading to 65% to 345% XRP price breakouts against Bitcoin as seen late 2024 and 2025.

The chart above also shows that the XRP/BTC pair is trading within a long consolidation range, which has previously acted as a strong launching pad for the ratio.

The last time XRP bottomed against Bitcoin around this zone was in June 2025. It marked the beginning of a 61% increase in the XRP/BTC ratio, accompanying a 92% XRP price rally to a multi-year high of $3.66.

Other instances shown by the yellow bars in the chart reinforce the reliability of this level in marking macro bottoms for XRP/BTC. 

MVRV Z-Score suggests XRP price is bottoming

XRP’s MVRV Z-score is hovering near zero, a level that historically aligns with accumulation zones and market bottoms.

This indicates that most holders are close to breakeven, reducing sell pressure and signalling potential downside exhaustion. Similar patterns appeared in 2021, 2022 and 2024 before major rallies.

Note that the last time XRP’s MVRV Z-score fell to similar levels in late 2024 coincided with a macro market bottom at $0.30 and preceded a multi-month rally, with the XRP/USD pair rising 500% to a multi-year high above $3. 

Meanwhile, the 0.80 MVRV pricing band, which has historically marked cycle bottoms, is currently at $1.14, coinciding with a 15-month low reached on Feb. 6.

These onchain metrics suggest that XRP is undervalued and may continue the ongoing recovery, potentially rising toward $1.70 or higher

XRP price must hold above $1.30 

Meanwhile, XRP/USD remains cautiously bullish as long as it holds the $1.25-$1.30 support zone. 

“$XRP is sustaining the major support zone between $1.30-$1.25 levels since early Feb’26,” trader ChiefraT said in an X post on Friday, adding:

“If this zone continues to hold, then a short-term bounce towards $1.45 can’t be ruled out.”

The importance of this support level is reinforced by cost basis distribution. The heatmap below shows that nearly 1.73 billion XRP were acquired around this price.

Below that, the next line of defence is the $1.15 demand zone, where the 200-week simple moving average is. 

If XRP/USD drops below this level, it would be in a free-fall toward the measured target of the bear flag at $0.80, or 41% below the current price.

As Cointelegraph reported, holding $1.27-$1.30 would be a sign of strength among the bulls who must push the XRP/USD pair toward the $1.61 range high to regain control.
