Strategy said it added $525M to its USD reserve this week, lifting the cash pile to $3.75B — enough to cover roughly 2.1 years of its preferred-stock dividends and debt interest.

The reserve is designed to service those obligations without touching Strategy's 843,775 BTC (about $63B), a position it has held unchanged for weeks as it raised cash through share sales rather than new coin buys.

Separately, a filing shows Strategy repurchased $25M of its STRC "Stretch" variable-rate preferred — the first buyback executed under a $1B Digital Credit Securities repurchase program authorized on June 29, aimed at supporting STRC's price near its $100 par after it slid to record lows.

An attacker seized owner privileges over the smart contract that issues WEMIX's dollar-pegged stablecoin on July 26, abnormally minting around $6.25M worth of tokens.

The freshly minted stablecoin was swapped into WEMIX and USDC, and roughly $724K was bridged off WEMIX 3.0 to Ethereum and BNB Chain before it could be stopped. No user wallets were compromised.

In response, WEMIX suspended all WEMIX 3.0 bridges (including Chainlink CCIP and the PLAY Bridge), paused affected liquidity pools and the stablecoin module, flagged the attacker's addresses and asked exchanges to freeze the funds. Blockchain security firms are tracing the flows.

It is the network's second major security incident in about 18 months, after roughly $6M was drained from the Play Bridge Vault in February 2025.

Storj Labs, the company behind the decentralized cloud storage network, filed for voluntary Chapter 11 reorganization on July 26 in the U.S. Bankruptcy Court for the Northern District of West Virginia.

The company says the filing resolves legacy obligations from an earlier chapter of the business, while operations, service and the network keep running normally with no anticipated interruption for customers.

"The business underneath is strong and right-sized. What holds it back are legacy obligations from an earlier chapter. This process lets us resolve them in an orderly way," said Kaloyan Raev, Director of Software Engineering at Storj.

Storj also intends to propose a mechanism for token holders to participate in equity of the restructured company, subject to court approval and creditor priority. STORJ trades near $0.074, down about 75% over the past year.

SK Group and NVIDIA expanded their partnership on July 24 into a $500 billion-plus programme covering AI factories and next-generation memory across Korea.

SK Telecom will build a 2-gigawatt-scale AI Cloud on NVIDIA's DSX platform with Vera Rubin accelerated computing and SK hynix HBM4 memory, with the first AI factory planned for 2027.

SK hynix separately signed a long-term AI memory supply deal with NVIDIA, co-developing next-generation HBM for large language model training, agentic AI and physical AI.

"Together with SK Telecom and SK hynix, we are building a new generation of AI factories that will power Korea's next wave of growth," said NVIDIA CEO Jensen Huang.

At Galaxy Unpacked on July 22, Samsung said Wallet will move beyond cards and cash to hold stablecoins natively, folding payments, rewards and digital assets into one app.

Product manager Lee Dinham said the move would make Samsung one of the first major mobile brands to bring native stablecoins to a smartphone, for fast and trusted transfers of digital value.

No stablecoins, launch window or partners were named. Galaxy owners in the US have been able to buy crypto inside Wallet through Coinbase since October 2025, a tie-up that covered more than 75 million devices.

New registrations, deposits and new trading orders were suspended at 01:30 UTC on July 26, hours after the exchange published its wind-down notice.

All trading services stop on August 26 at 01:00 UTC. Platform operations formally cease on January 31, 2027, with withdrawals available until then. BitMart urged users to close positions, complete KYC and pull assets out early.

The company cited its operating conditions, the market environment and a change in strategic direction. No buyer, successor venue or migration path was named.

Colibri Trade, a crypto-native quantitative trading firm built specifically for prediction markets, has secured a $1,000,000 trading capital allocation, deployed through Colibri's market-making infrastructure, a mandate rather than a venture investment.

Colibri already runs over $10M in monthly trading volume across 70+ markets spanning crypto, sports, politics, geopolitics, and macro, with 24/7 automated execution and risk management active on leading venues including Polymarket, Kalshi, Limitless, Predict fun, XO Markets, and Opinion.

The new capital will flow directly into Colibri's systems to provide continuous two-sided liquidity, deepen order books, and tighten spreads across those venues.

The fresh fundds comes as prediction markets face a widening gap between user growth and market structure, liquidity remains fragmented across venues, order books thin outside headline markets, and spreads inconsistent, limiting how efficiently capital actually gets deployed.

Colibri's infrastructure is positioned to close that gap, offering fair-value pricing and consistent quotes where books would otherwise stay shallow.

HTX — the global crypto exchange formerly known as Huobi — has been included in the European Union's latest package of sanctions targeting Russia, according to a report from Reuters.

The inclusion places a major exchange directly under EU restrictions, underscoring the bloc's tightening focus on crypto platforms within its Russia sanctions regime.
