Méliuz Bitcoin Buy, Ethereum Security Push & JPMorgan’s Blockchain Move

Big things are happening in crypto. Each week, we round up the biggest updates from StealthEX and CryptoDaily. No fluff—just the news that matters. Want to know what’s hot right now? We’ve put together a simple recap that highlights the key stories. It’s fast, clear, and easy to follow. You’ll always know what’s going on without getting lost in the noise.

Brazilian Fintech Méliuz Goes All-In on Bitcoin

Brazil’s fintech scene just saw a major shake-up. Méliuz, a local financial services firm, has officially entered the Bitcoin treasury game. The company spent $28.4 million to buy Bitcoin as part of a long-term shift in its business strategy. With that, it became the first Brazilian firm of its kind to take this bold step.

Company chairman Israel Salmen confirmed the move publicly. He called it a major day for both Méliuz and Brazil’s evolving financial sector. This wasn’t a secretive purchase either—shareholders were fully on board. Most voted in favor of turning Méliuz into a Bitcoin treasury firm listed on Brazil’s stock market.

In total, the company now holds over 320 Bitcoins, acquired at an average price of around $101,700 each. 

Unlike other firms using crypto to hedge inflation, Méliuz is treating Bitcoin as a core asset. The goal? To increase how much Bitcoin is tied to each share of the company.

The firm also joined Bitcoin For Corporations and met with MicroStrategy’s Michael Saylor for guidance. Since March, Méliuz stock has soared more than 117%, showing the market approves.

Ethereum Sets New Security Ambitions With ‘Trillion Dollar’ Upgrade

Ethereum is raising the bar. The Foundation behind the world’s second-largest blockchain has launched a new security push. Called the Trillion Dollar Security project, it aims to make Ethereum strong enough to support trillions of dollars in value—safely and reliably.

This move isn’t just about fixing bugs. It’s about building trust. Ethereum wants governments, banks, and institutions to feel confident storing massive sums on its blockchain. That means going beyond what’s worked so far.

The plan includes a deep review of every piece of the Ethereum stack. Wallets, smart contracts, consensus code, even DNS risks—all of it is being mapped and tested. Based on those results, Ethereum will upgrade tools, patch vulnerabilities, and roll out new protections.

The initiative is led by protocol expert Fredrik Svantes and security strategist Josh Stark. They’re joined by top names in blockchain safety, including samczsun, Mehdi Zerouali, and Zach Obront. Each brings years of experience with audits, zero-knowledge tech, and smart contract protection.

But they can’t do it alone. The Ethereum Foundation is calling on the entire community—users, devs, and security firms—to join the effort. Feedback and collaboration are key to making the ecosystem stronger.

Ethereum’s message is clear: security isn’t just a feature. It’s the foundation of the future.

JPMorgan Enters Public Blockchain with Tokenized Treasury Deal

JPMorgan just took its biggest step yet into public blockchain. The banking giant completed a test transaction using digital U.S. Treasuries—bridging private and public chains for the first time.

The deal was handled by Kinexys, JPMorgan’s blockchain arm. It involved settling tokenized Treasury bonds between its internal blockchain and a public one hosted by Ondo Finance. This wasn’t just a tech demo—it used real infrastructure, real value, and real protocols.

The secret weapon behind it all? Chainlink’s Cross-Chain Interoperability Protocol. It acted as the glue, connecting JPMorgan’s private system to the open blockchain world. The transaction followed a delivery-versus-payment model, meaning money and bonds were exchanged at the same time. That setup removes the risk of either side backing out mid-trade.

This kind of cross-chain settlement tackles a long-standing problem in global finance. Payment delays and mismatched systems cost the industry nearly $1 trillion over the past decade. Blockchain can streamline those processes, and JPMorgan is now showing how.

The bank didn’t do it for headlines. It’s part of a bigger plan to upgrade old systems with modern tech. And it’s a signal: public blockchains are no longer off-limits for Wall Street.

FalconX Teams Up with Standard Chartered to Expand Crypto Access

A major bridge just formed between old finance and new tech. FalconX, a leading crypto brokerage, has partnered with global banking giant Standard Chartered. The goal? Make it easier for big institutions to trade digital assets worldwide.

This deal gives FalconX access to the bank’s trusted systems, including currency exchange and payment rails. That means faster, safer, and more reliable crypto transactions for hedge funds, asset managers, and other institutional clients.

It’s the first time FalconX has teamed up with a traditional bank of this size. The rollout begins in Singapore, then expands to the Middle East and U.S. markets. These are regions where interest in crypto is rising quickly, and now they’ll have better tools to match.

Standard Chartered isn’t new to crypto. It already offers custody services, runs spot trading desks, and has a digital asset unit in the EU. This partnership shows they’re doubling down.

Both sides see the same future: more institutions entering the crypto space, but needing trusted infrastructure to do it. Together, FalconX and Standard Chartered aim to provide just that.

As more banks follow suit, the line between crypto and traditional finance keeps fading.

Coinbase Faces $400M Fallout After Insider-Driven Cyberattack

Crypto giant Coinbase has revealed details of a major security breach. Hackers bribed overseas contractors to steal user data, triggering a cyberattack that could cost the company $400 million to resolve.

According to Coinbase, the attackers gained access to less than 1% of its user base. Still, they collected enough personal info—like emails, addresses, and ID images—to launch convincing scams. Some users were tricked into sending their crypto to wallets controlled by the attackers.

It all started with cash bribes. A small group of outsourced support agents were paid to leak internal tools. Hackers used that access to impersonate Coinbase staff and contact users under false pretenses. Then came the ransom demand: $20 million, or the data would be made public.

Coinbase refused. Instead, it fired the involved staff and contacted law enforcement. The company is also setting up a $20 million reward fund for tips that lead to arrests.

Crucially, Coinbase says no passwords, keys, or funds were exposed through the breach itself. Users who were scammed are being reimbursed.

The timing is critical. Coinbase is about to enter the S&P 500, a major milestone. But the attack is a stark reminder—crypto security is still a moving target.

Abu Dhabi Invests $408M in Bitcoin ETF, Signaling Bigger Crypto Vision

Abu Dhabi is making another move in the digital asset world. Through its sovereign wealth fund, Mubadala, the emirate has invested $408 million into BlackRock’s iShares Bitcoin Trust (IBIT). It’s one of the largest Bitcoin ETF allocations ever made by a state-backed entity.

Instead of holding Bitcoin directly, Mubadala went the ETF route. This avoids the complications of custody and compliance that often come with owning crypto outright. With IBIT, the fund gets exposure to Bitcoin’s price while staying inside a secure, regulated framework.

The latest purchase brings Mubadala’s total Bitcoin ETF stake close to $1 billion. While that’s only a small slice of its $302 billion in managed assets, it shows strong interest in crypto’s long-term potential.

The move is part of Abu Dhabi’s broader digital asset strategy. The city has opened its doors to blockchain firms and recently granted licenses to major players like Circle. With tech hub Hub71 leading the charge, the emirate is building a serious crypto ecosystem.

Abu Dhabi isn’t just investing—it’s positioning itself as a leader in the region’s growing digital economy.

New Bitcoin Firm Starts Strong with $458M BTC Buy-In

A new player has entered the Bitcoin space—and it’s not wasting time. Twenty One Capital, led by Jack Mallers, just made headlines by buying nearly 5,000 Bitcoin in its first major move.

The purchase was valued at $458.7 million and was completed shortly after the company went public through a SPAC merger with Cantor Equity Partners. The Bitcoin was sourced from Tether, which held the funds in a private wallet before transferring them under a structured deal.

This buy instantly positioned Twenty One Capital among the top three corporate Bitcoin holders in the world, trailing only MicroStrategy and Marathon Digital. It also raised the firm’s total BTC holdings to over $4 billion, a huge statement from a brand-new operation.

The strategy is clear. Mallers is following the model used by Michael Saylor—turning corporate cash into Bitcoin as a store of value. The approach is gaining traction among firms looking to move away from traditional currencies and inflation risks.

Backers include Tether, Bitfinex, and even SoftBank, which holds a smaller stake. The message is simple: Bitcoin isn’t just for tech startups anymore—it’s fast becoming a core asset for major financial players.

MEXC Clears Security Audit With No Major Flaws Detected

Crypto exchange MEXC has passed a full security check on its mobile app, showing no signs of major risk. The review was done by Hacken, a cybersecurity firm known for auditing blockchain platforms.

The audit focused on how the app handles user data, trade execution, and fund transfers. According to the results, there were no critical or high-risk issues. A few smaller problems were found early on, but MEXC fixed them before the final report.

The audit used penetration testing to see how the app would respond to real-world attacks. Hacken confirmed that MEXC met standard security benchmarks and pointed out that the app’s design puts both safety and ease of use first.

MEXC’s Tracy Jin said third-party checks like this are key to building trust with users. The exchange has been working to increase transparency, especially after past scandals in the crypto world.

Earlier this year, MEXC released a Proof of Reserves showing that most user funds are kept in secure cold storage. The platform also launched a $30 million Web3 fund to back new crypto startups.

With regulators watching the space more closely, MEXC is one of several exchanges working to prove they can operate safely and openly.
