UK fintech platform Stratiphy has introduced a new product aimed at restoring tax-efficient access to crypto exchange-traded notes (ETNs), following regulatory changes that had effectively blocked retail investors from using traditional routes.

Regulatory Changes Created a Market Gap

In October 2025, the Financial Conduct Authority lifted its long-standing ban on retail access to crypto ETNs linked to assets like Bitcoin and Ether. Initially, these products could be held within standard stocks and shares Individual Savings Accounts (ISAs), allowing for tax-free exposure.

However, the situation changed at the start of the new tax year when HM Revenue & Customs ruled that newly purchased crypto ETNs would no longer qualify for those ISAs.

Instead, they were restricted to Innovative Finance ISAs, a less commonly used structure typically associated with peer-to-peer lending. Since no major platform offered both crypto ETNs and IF ISAs, retail investors were left with limited practical access.

Stratiphy Steps In With a New Solution

Stratiphy’s new offering aims to bridge that gap by providing a compliant, tax-free route back into crypto ETNs.

The platform is launching with three ETNs issued by 21Shares, covering:

• Bitcoin exposure
• Ether exposure
• A hybrid Bitcoin and gold product

This setup gives investors a way to regain tax-efficient exposure to crypto markets within the current regulatory framework.

Existing Platforms Fall Short

While crypto ETNs are already available through platforms like:

• Interactive Investor
• Freetrade
• Revolut

none currently offer Innovative Finance ISAs, which limits their usefulness for tax-free investing under the updated rules.

Additionally, IF ISAs fall outside the UK’s Financial Services Compensation Scheme, adding another layer of consideration for investors.

Growing Interest in Regulated Crypto Products

Despite regulatory hurdles, demand for crypto ETNs remains strong.

A study by IG Group found that:

• Around 30% of UK adults are open to investing in crypto via ETNs
• The UK crypto market could grow by up to 20% following broader access

This interest is largely driven by the perceived safety and regulatory oversight of ETNs compared to direct crypto ownership.

Broader Regulatory Developments Underway

The UK is continuing to refine its approach to crypto regulation.

The Financial Conduct Authority has launched consultations ahead of a comprehensive framework expected to take effect in October 2027, covering:

• Stablecoins
• Trading platforms
• Custody services
• Staking

These efforts aim to bring greater clarity and structure to the market while supporting innovation.

A Step Toward Restoring Access

Stratiphy’s launch highlights how fintech firms are adapting to evolving regulations to maintain investor access.

By reopening a tax-efficient pathway to crypto ETNs, the platform could play a key role in reconnecting UK retail investors with regulated digital asset exposure.

Privacy-focused crypto protocol Umbra has temporarily taken its front-end interface offline in an effort to slow down hackers attempting to move stolen funds.

The move comes amid heightened scrutiny following a series of major exploits across the crypto ecosystem.

Front-End Taken Offline After Suspicious Activity

Umbra said it identified roughly $800,000 in stolen funds being routed through its protocol. In response, the team placed its hosted front end into maintenance mode.

The protocol noted that the interface will remain offline until it is confident that restoring it will not interfere with ongoing recovery efforts.

This action follows the recent exploit of Kelp DAO, where attackers stole over $280 million, with some reports linking the movement of funds through Umbra.

Limits of Control in Decentralized Systems

Despite shutting down its front end, Umbra acknowledged a key limitation: it cannot stop users from interacting directly with its smart contracts.

Because the protocol is open-source:

• Users can access it through self-hosted interfaces
• Alternative front ends can be deployed independently
• Smart contracts remain fully operational onchain

This highlights the broader challenge of controlling decentralized infrastructure once it is live.

Debate Over Responsibility Intensifies

The situation has reignited debate around developer responsibility in decentralized systems.

Roman Storm, co-founder of Tornado Cash, argued that disabling a front end may not be enough to satisfy regulators.

Storm, who was previously convicted in a high-profile case, said authorities may still view control over a user interface as control over the protocol itself.

He warned that:

• Modifying or shutting down a front end could be interpreted as governance authority
• Developers may still face legal accountability regardless of decentralization claims

Umbra Defends Its Design

Umbra pushed back on claims that its protocol is useful for laundering funds.

The team emphasized that:

• The protocol primarily protects the receiver’s identity, not the sender’s
• Transactions remain traceable onchain
• Stolen funds routed through Umbra can still be identified

It also confirmed that it is working with security researchers to track suspicious activity.

Ongoing Pressure on Privacy Tools

The incident reflects growing pressure on privacy-focused crypto tools as regulators and law enforcement target illicit fund flows.

While some platforms have taken steps to freeze or block hacker activity, decentralized protocols like Umbra face structural limitations in enforcement.

A Balancing Act Between Privacy and Security

Umbra’s decision underscores a broader tension in crypto:

• Preserving user privacy
• Preventing misuse by bad actors

As exploits continue and scrutiny increases, protocols may face tougher choices around how much control they can or should exert over their systems.

A major Wall Street law firm has admitted fault after submitting a legal filing filled with errors caused by artificial intelligence, raising fresh concerns about AI use in high-stakes professional work.

AI Hallucinations Lead to Dozens of Errors

Sullivan & Cromwell issued a formal apology to a federal judge after a court document included around 40 incorrect citations and related mistakes.

Andrew Dietderich, co-head of the firm’s global restructuring team, acknowledged the issue in a letter to Martin Glenn of the US Bankruptcy Court for the Southern District of New York.

“We deeply regret that this has occurred,” Dietderich said, taking responsibility for the filing and confirming that the firm failed to meet required accuracy standards.

Internal Safeguards Were Not Followed

Dietderich explained that the firm already has internal policies governing AI use, including:

• Verifying citations generated by AI tools
• Reviewing all legal submissions before filing

However, in this case, those safeguards were not properly followed. As a result, the review process failed to catch both AI-generated inaccuracies and additional manual errors.

Growing Problem Across Legal Industry

The incident highlights a broader issue with AI “hallucinations,” where tools generate false or misleading information that appears credible.

According to legal technologist Damien Charlotin, there have been:

• Over 1,300 recorded AI-related errors in legal filings globally
• More than 900 cases in the United States alone

Most of these involve fabricated or incorrect legal citations, though flawed legal arguments have also surfaced.

Firm Launches Internal Investigation

Sullivan & Cromwell has since taken immediate steps to address the issue, including:

• Conducting a full internal review
• Assessing whether stronger safeguards are needed
• Considering updates to training and oversight processes

The firm also reached out to Boies Schiller Flexner LLP, which first flagged the errors, to acknowledge and apologize for the mistake.

AI Use in Law Under Scrutiny

The situation adds to growing scrutiny over how AI is being used in professional environments, especially in fields like law where accuracy is critical.

While AI tools can improve efficiency, this case shows that without strict oversight, they can introduce serious risks.

A Reminder of Human Accountability

Despite increasing reliance on AI, the responsibility for accuracy still lies with professionals.

As Dietderich noted, ensuring the reliability of legal filings is ultimately a human obligation, regardless of the tools used.
