Magic Eden, the prominent NFT marketplace best known for its deep roots in the Solana blockchain ecosystem, is set to close its Bitcoin and EVM-based trading platforms and discontinue support for its multi-chain wallet.

Magic Eden refocuses on Solana, winds down Bitcoin and EVM services

Magic Eden originally rose to prominence by offering a user-friendly platform for buying, selling, and trading digital collectibles, especially non-fungible tokens (NFTs), on the high-throughput Solana network.

Over time, the platform expanded into Bitcoin Ordinals and Ethereum Virtual Machine (EVM) chains such as Ethereum, Polygon, and Avalanche in an effort to capture a broader share of the burgeoning NFT market.

However, new reports say the company will begin shutting down its Bitcoin and EVM marketplaces in the first week of March 2026, with its cross-chain wallet entering export-only mode by mid-March and fully ceasing service in early April. Support for Solana-based NFTs and assets will continue uninterrupted.

The move could be a strategic realignment rather than a retreat.

By concentrating on its core Solana busines, where the majority of its trading volume has historically originated, Magic Eden aims to streamline operational complexity and refocus engineering resources on strengthening features, liquidity, and community engagement within its original ecosystem.

Affected users are being urged to withdraw any assets held in the Bitcoin and EVM marketplaces or within the multi-chain wallet before support ends to avoid the risk of losing access. As the NFT sector evolves, Magic Eden’s decision highlights broader market trends toward specialization and platform consolidation.

TLDR:

• OpenAI signed a deal to deploy AI models on U.S. Department of War classified networks on Feb. 28, 2026.
• The agreement bans domestic mass surveillance and requires human control over lethal force decisions.
• Anthropic reportedly refused a similar Pentagon deal, citing autonomous weapons and surveillance risks.
• Backlash on X was swift, with thousands of users announcing plans to cancel ChatGPT subscriptions.

OpenAI has agreed to deploy its AI models on classified U.S. Department of War networks, CEO Sam Altman announced. The deal follows reports that Anthropic publicly declined similar Pentagon demands over autonomous weapons and surveillance concerns. 

Altman posted the announcement to X, where it quickly drew millions of views and thousands of replies. The reaction online was largely critical, with many users threatening to cancel their ChatGPT subscriptions.

OpenAI and the Department of War Reach Classified AI Agreement

The agreement allows OpenAI models to operate within DoW classified systems under specific conditions. 

Altman stated the deal includes explicit prohibitions on domestic mass surveillance. It also requires human oversight for any use of force, including autonomous weapons systems. Deployment will occur on cloud networks only, with OpenAI personnel embedded to monitor model behavior.

Altman noted on X that the DoW agreed with these core safety principles. 

According to the post, those principles are also reflected in existing law and policy. OpenAI said it will build technical safeguards to keep models aligned with the agreement’s terms. The company also called on the DoW to extend the same terms to all AI companies.

Altman framed the deal as part of a broader effort to reduce friction between AI companies and the government. He wrote that OpenAI wants to move away from legal and governmental conflicts. 

The announcement signals a shift toward negotiated frameworks rather than standoffs. OpenAI described its mission as serving all of humanity amid a “complicated, messy, and sometimes dangerous world.”

The post received over 11,000 likes within hours of going live. Reposts and quote replies numbered in the thousands. Despite the scale of engagement, most visible reactions skewed negative.

Anthropic’s Refusal Puts Spotlight on OpenAI’s Pentagon Move

Reports from the previous day indicated Anthropic CEO Dario Amodei refused similar Pentagon demands. The refusal reportedly centered on concerns about enabling mass surveillance and autonomous weapons. 

Amodei allegedly offered to help the DoW transition to another provider rather than comply. That stance drew widespread praise from AI safety advocates and researchers.

OpenAI’s subsequent agreement was widely read as stepping into the gap Anthropic left. Critics on X accused the company of opportunism. Several users announced they were switching from ChatGPT to Claude. Some described the move as contradicting OpenAI’s own stated safety values.

Block, Inc. will reduce its workforce by nearly half, cutting more than 4,000 jobs as CEO Jack Dorsey said the fintech firm restructures around artificial intelligence and leaner teams.

Wall Street cheers Jack Dorsey’s AI restructure

In a note shared publicly, Jack Dorsey said the company will shrink from over 10,000 employees to just under 6,000. He described the move as “one of the hardest decisions in the history of our company,” adding that affected employees would be notified the same day.

Despite the scale of the layoffs, Dorsey emphasized that Block is not facing financial distress. He said gross profit continues to grow, customer numbers are rising, and profitability is improving.

Instead, he framed the cuts as a proactive shift driven by the rapid advancement of intelligence tools that are reshaping how companies are built and operated.

“We’re already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working,” Dorsey wrote, arguing that acting decisively now would avoid repeated rounds of layoffs that could damage morale and trust.

Employees leaving the company will receive 20 weeks of salary plus an additional week per year of tenure, equity vesting through the end of May, six months of healthcare coverage, their corporate devices, and $5,000 in transition support. Terms will vary internationally depending on local regulations.

Dorsey said internal communication channels would remain open through Thursday evening to allow departing staff to say goodbye, and he plans to host a live video session to address employees directly.

The market’s reaction to Jack Dorsey’s “leaner, meaner” pivot was nothing short of explosive. As news broke regarding the reduction of 4,000 roles, Block Inc. shares ignited in after-hours trading, surging by more than 23%.

The chart reflects a dramatic vertical shift as investors pivoted from uncertainty to overwhelming optimism, interpreting the layoffs not as a sign of corporate distress, but as a commitment to long-term profitability and AI-driven efficiency.

Disgraced FTX founder Sam Bankman-Fried has reignited controversy from prison after publicly endorsing the proposed CLARITY Act, calling it a “huge milestone for crypto” and “a huge achievement” for Donald Trump.

Sam Bankman-Fried backs CLARITY Act, draws swift rebuke from Lummis and Warren

In a post on X, Bankman-Fried claimed he had championed similar legislation aimed at limiting the regulatory authority of former SEC Chair Gary Gensler before his prosecution. He suggested that Gensler “helped Biden’s DOJ put me behind bars,” reviving familiar allegations that his case was politically influenced.

The comments quickly drew bipartisan backlash.

Senator Cynthia Lummis responded sharply, writing: “Someone’s looking for a pardon and doesn’t realize the CLARITY Act would have you locked up for much longer than 25 years.”

She added that her crypto legislation differs fundamentally from what she described as the bill Bankman-Fried “tried to buy from Congress” in 2022. “We do not need—nor want—your support,” she said.

Senator Elizabeth Warren also weighed in, warning that Bankman-Fried’s endorsement should “set off alarm bells.” Warren reiterated her stance that any crypto market structure legislation must prioritize investor protection and financial stability.

Bankman-Fried, who is serving a lengthy federal sentence following his conviction over the collapse of FTX, has recently attempted to re-enter public discourse through media outreach and social media commentary. Previous efforts to sway political opinion, including outreach linked to Trump, have largely failed to gain traction.

The episode shows the heightened political sensitivity surrounding crypto regulation, particularly as lawmakers debate market structure reforms amid lingering fallout from FTX’s multibillion-dollar collapse.

Federal authorities have arrested Christopher Alexander Delgado, the founder and CEO of Goliath Ventures, on federal charges tied to an alleged $328 million Ponzi crypto scam, the U.S. Department of Justice announced.

Goliath Ventures CEO arrested in $328M crypto scam

Delgado, 34, of Apopka, Florida, was taken into custody on a criminal complaint filed in the United States District Court for the Middle District of Florida, where he is charged with wire fraud and money laundering.

If convicted on all counts, he could face up to 30 years in federal prison.

Prosecutors allege Delgado’s scheme ran from January 2023 through January 2026, during which he solicited investors to put money into purported cryptocurrency “liquidity pools” that promised steady monthly returns. In reality, federal officials say only about $1 million of the funds was actually invested in legitimate crypto assets.

The bulk of the more than $300 million collected from victims was used to pay earlier investors and finance Delgado’s lavish lifestyle, including luxury travel, company-sponsored events, and purchases of multi-million-dollar homes in central Florida.

According to court filings, victims were drawn in through personal referrals, slick marketing materials, and high-end networking events aimed at projecting legitimacy. At the scheme’s unraveling, investors seeking withdrawals were met with delays, inconsistent explanations, and restricted access to account information.

Federal law enforcement agencies including IRS Criminal Investigation and Homeland Security Investigations spearheaded the probe. Victims are being notified of their rights under the Crime Victims’ Rights Act, and authorities have invited potentially unidentified victims to come forward.

The arrest marks one of the largest alleged crypto-related fraud cases in recent years and underscores ongoing regulatory and criminal scrutiny of digital asset investment schemes.

An autonomous AI security tool caught a bug in the XRP Ledger that, if left undetected, could have let an attacker steal funds from any account on the network without ever touching the victim’s private keys.

The vulnerability, disclosed Thursday by XRPL Labs, sat in the signature-validation logic of the Batch amendment, a pending upgrade that would allow multiple transactions to be bundled and executed together.

The amendment was still in its voting phase among validators and had not been activated on mainnet, meaning no funds were ever at risk. But the exploit path was about as bad as it gets for a blockchain.

Here’s what the bug did in plain terms. Batch transactions let users bundle several operations into one. Because the individual transactions inside the batch don’t carry their own signatures, the system relies on a list of batch signers to confirm that every account involved has authorized the bundle.

The validation function that checked those signers had a critical loop error. If it encountered a signer whose account didn’t yet exist on the ledger, and whose signing key matched their own account — the normal case for a brand-new account — it immediately declared the entire check successful and stopped looking at the rest of the list.

An attacker could exploit this by constructing a batch with three transactions. The first creates a new account the attacker controls. The second is a simple transaction from that new account, making it a required signer. The third is a payment from the victim’s account to the attacker.

Because the new account doesn’t exist yet when validation runs, the signer check exits early after the first entry and never verifies the second. The victim’s funds move without their keys ever being involved.

Pranamya Keshkamat and Cantina AI’s autonomous security tool Apex identified the flaw through static analysis of the codebase on Feb. 19 and submitted a responsible disclosure. Ripple’s engineering team validated the report the same evening with an independent proof-of-concept.

The response was fast. Validators on the network’s Unique Node List were immediately advised to vote “No” on the amendment.

An emergency release, rippled 3.1.1, was published on Feb. 23, marking both the Batch and the related fixBatchInnerSigs amendments as unsupported to prevent them from ever activating. A corrected replacement called BatchV1_1 has been built and is under review, with no release date set.

The fact that an AI tool found this is notable on its own.

XRPL Labs said it would add AI-assisted code audit pipelines as a standard step in its review process going forward, alongside expanded static analysis specifically designed to catch the kind of premature loop exits that caused this bug.

Bitcoin’s attempt to reclaim $70,000 earlier in the week lasted about 48 hours.

The largest cryptocurrency slid to $65,735 in early Asian hours on Saturday, down 3% over the past day and 2.8% on the week. Wednesday’s rally, which came within touching distance of $70,000, has now given back more than half its gains as broader risk sentiment deteriorated through Thursday and Friday’s U.S. sessions.

Altcoins took a harder hit. Solana dropped 6.7%, ether fell 6.2%, dogecoin shed 5.1%, and XRP lost 4%. The losses pushed most major tokens into the red on a weekly basis, erasing the altcoin outperformance that had been the week’s most encouraging signal. BNB held up better than most, down just 2.5%.

The trigger was familiar. Friday’s U.S. session saw the S&P 500 close down 0.4%, the Nasdaq 100 drop 0.3%, and the Dow fall 1.1%. Nvidia, still digesting its post-earnings reaction, shed another 4.2%.

A hotter-than-expected 0.5% jump in producer prices added fuel, signaling inflationary pressure that may keep the Fed from cutting rates anytime soon. Block Inc.’s massive layoffs fanned broader anxiety that AI is starting to displace jobs across the economy rather than just creating them.

Crypto followed equities lower, but as usual, with amplified magnitude. A 0.4% drop in the S&P became a 3% drop in bitcoin and a more than 6% drop in altcoins. The leverage that re-entered the system during Wednesday’s rally got flushed on the way back down.

The irony is that the institutional flow data this week was actually strong.

U.S. spot bitcoin ETFs added $1.1 billion in three days, putting them on pace for their best week in months. But ETF inflows haven’t been enough to overcome the broader macro headwinds.

“Over-analysis of short-term price movements is misguided,” said Dom Harz, co-founder of bitcoin finance firm BOB said in an email. “Bitcoin’s volatility is no surprise, particularly for early investors who have experienced previous cycles. What’s different this time is the type of capital behind the emerging asset class.”

Meanwhile, CryptoQuant data shows USDT stablecoin reserves on exchanges have fallen from $60 billion to $51.1 billion over the past two months, a decline the firm warned could trigger a “massive sell-off” if reserves drop below $50 billion.

Elsewhere, Strategy shares topped the list of large U.S. companies by short interest volume as markets increasingly question the sustainability of the firm’s debt-funded bitcoin buying program.

And on the Ethereum side, large holders have started selling at a loss, with DAT company ETHZilla officially abandoning its ETH accumulation strategy and rebranding to focus on tokenized real-world assets instead.

Bitcoin is now back in the middle of the $60,000-$70,000 range it has been stuck in since the Feb. 5 crash. Wednesday proved the top of that range is resistance. The question heading into March is whether the bottom still holds.

MetaMask and Mastercard have officially launched the MetaMask Card across the United States, marking a significant step in bringing cryptocurrency spending into everyday commerce.

New MetaMask and Mastercard card lets users spend crypto

The announcement follows successful pilot programs in Europe and the UK, and now brings the self-custodial crypto payment card to 49 U.S. states, including New York for the first time.

Spot Bitcoin exchange-traded funds pulled in more than $1 billion of net inflows over three trading sessions this week, a reversal that came even as Bitcoin remained well below its peak.

The US-listed spot Bitcoin (BTC) ETFs logged a combined $1.02 billion in inflows from Tuesday to Thursday, according to data from SoSoValue. The funds pulled in $506.51 million on Wednesday, the largest single-day total during the three days.

On Friday, ETF analyst Nate Geraci said in a post on X that investors appeared to be “buying the dip” amid the recent downturn.

He said spot Bitcoin ETFs have seen about $6.5 billion in outflows since Bitcoin’s record high in early October, a figure he described as modest relative to the $55 billion the category has absorbed since January 2024.

“50% drawdowns are walk in the park for long-time BTC investors,” Geraci wrote. “But appears newer ETF investors aren’t worried either.”

Flows reverse multi-week outflow streak

This week’s inflows follow five consecutive weeks of net withdrawals, with the last two weeks of January recording a combined $2.82 billion in outflows.

The rebound was led by BlackRock’s iShares Bitcoin Trust (IBIT), which logged $275.82 million in net inflows on Thursday alone. Fidelity’s FBTC and Ark 21Shares’ ARKB posted outflows, but were outweighed by gains in other funds including Bitwise’s BITB and Grayscale’s BTC.

Altcoin ETFs have also turned positive in recent trading sessions. Spot Ether (ETH) ETFs added about $173 million over the same three-day period, while Solana funds logged roughly $35 million in inflows. Meanwhile, XRP (XRP) ETFs logged a modest $7 million in inflows.

Analysts flag ETF flows as sentiment gauge

The inflows come as market participants discuss whether the recent selling pressure is easing. On Friday, several analysts said Bitcoin’s roughly 50% drawdown may be approaching exhaustion. 

CoinEx chief analyst Jeff Ko previously told Cointelegraph that improvements in spot ETF inflows suggest aggressive selling pressure may be fading. However, he said a sudden V-shaped recovery is unlikely after a steep decline. 

Bitrue research lead Andri Fauzan Adziima similarly pointed to oversold technical indicators and said sustained ETF inflows could serve as a catalyst for stabilization.
