Zilliqa Halts ZIL Over a Ledger Key-Leak Bug
Zilliqa suspended all native ZIL transactions after attackers began exploiting a private-key-leaking bug in its Ledger wallet app that had been dormant since 2019.
The flaw is in how the Ledger app generates nonces for EC-Schnorr signatures: the top 64 bits are fixed at zero, so an attacker can rebuild a full private key from just ~5 on-chain signatures. ZIL was drained from an offline cold wallet run by an exchange partner; Upbit and others froze ZIL deposits and withdrawals. Zilliqa has not disclosed the amount and urges users to retire exposed keys and wait for a fix from Zilliqa and Ledger.
Jack Dorsey Launches BUZZ to Take On Slack
Block, led by Jack Dorsey, has launched BUZZ, an open-source rival to Slack and GitHub where people and AI agents collaborate inside one shared workspace.
Every human and agent gets a cryptographic identity and its own permissions, running on the decentralized Nostr protocol. Agents join as full members, not command-only bots — Dorsey calls it “model-agnostic, decentralised, self-sovereign and open source.”
Zama Teams Up With Elliptic on Compliance
Confidentiality protocol Zama has partnered with blockchain-intelligence firm Elliptic to bring compliance screening to confidential onchain finance — without giving up privacy.
Zama builds a confidentiality layer for public blockchains using fully homomorphic encryption (FHE). Elliptic’s screening lets institutions meet AML and regulatory standards on transactions that stay encrypted — “compliant by design.”
Satsuma to Liquidate Its Bitcoin Treasury
Shareholders of UK Bitcoin-treasury firm Satsuma Technology have voted, with over 90% support, to sell off its entire Bitcoin stack, delist from London, and hand the capital back to its investors.
Satsuma will sell 668 BTC (~$43.5M) and return the capital to investors, overruling four of its six board members. It is a fast unwind: under a year ago it raised $218M in a ParaFi-led round and hired Mark Moss as chief bitcoin strategist.
Rhinofi Shuts Down Retail Services as Company Winds Down Consumer Offering
Rhinofi is discontinuing its retail offering at the end of July 2026, cutting off bridge access and transaction history for individual users. Anyone with funds, liquidity positions, or balances on the platform should withdraw before the deadline.
B2B clients remain unaffected and can keep using Rhinofi's Stablecoin Activation Stack by contacting the team directly.
The shutdown marks a notable exit for a bridge widely used during past airdrop farming seasons, reflecting a broader pullback among airdrop-linked infrastructure amid the current bear market.

Anthropic Offers Up to $50K in Claude Credits for Rare Disease Research
Anthropic has opened the first thematic call of its AI for Science program, giving researchers up to $50,000 in Claude credits over six months to work on rare genetic diseases.
The call runs two tracks: one for scientists doing basic research — with the Monarch Initiative as an early partner — and one for early-stage biotechs racing to compress drug-development timelines. Some 400M people live with one of 7,000+ rare diseases, yet each is studied in isolation. Applications are open through August 2, 2026, with credits usable on Claude Opus and other models approved for biology work.
The "buy crypto, become a treasury company" strategy is deep underwater
20 of 22 digital-asset treasuries are sitting on unrealized losses, about $30B combined at today's prices. Strategy (−$9.8B) and Bitmine (−$8.9B) carry 61% of the pain alone.
The only two names in profit? Both hold HYPE, not BTC or ETH.
Samsung Electronics has Launched Robotics Division
Samsung Electronics has set up a dedicated robotics division reporting straight to its CEO, aiming to make humanoid robots and AI a core growth engine.
The new RX (“Robotics eXperience”) unit will run Samsung’s mid- to long-term robotics strategy. It is led by EVP Lee Dongkun, who previously headed robotics strategy at Hyundai Motor Group, including its direction of Boston Dynamics. Samsung will deploy humanoids first in its factories, then move into home and retail, with agentic AI reshaping its plants by 2030. Its new “Shallow-π” tech cuts robot-control compute to a third.
Hashflow’s Website Goes Down, Raising Red Flags
Hashflow’s website is currently unreachable, and its HFT token sits near an all-time low of ~$0.0076 — months after Binance put the token under a delisting-risk monitoring tag.
Community members warn that a Discord link tied to Hashflow’s socials leads to a fake server and a wallet-draining phishing page mimicking collab.land, and claim the founders’ LinkedIn profiles were deleted. None of this is confirmed by the team or by security firms.
Until there’s an official statement, treat it as high-risk: do not connect your wallet to any “Hashflow” verification link, and revoke approvals to old Hashflow contracts.
GRVT Pushes TGE to July 30 as Multi-Exchange Launch Takes Shape
GRVT has moved its native token launch date from July 21 to July 30, opting to delay in favor of a coordinated debut across multiple major exchanges rather than a single-venue listing.
The team says the shift comes down to timing: GRVT is launching simultaneously on several major exchanges, with the lineup still growing. Initial listings have already been confirmed since the last announcement, and more are in final stages. Listings follow coordinated timelines and can only be confirmed once agreements are fully executed, which is why the full exchange list hasn't been revealed yet.

FBI Arrests Man Accused of Using Steam Games to Drain Crypto Wallets
U.S. prosecutors have charged a Florida man with distributing malware-laden video games on Steam as part of a scheme that allegedly infected thousands of victims and drained their crypto wallets.
According to a criminal complaint, the FBI arrested 21-year-old Zyaire Wilkins on Tuesday, accusing him and several unnamed co-conspirators of publishing malicious games, including BlockBlasters, Dashverse, Lampy, Lunara, and PirateFi, on Steam over the past two years.

Others: Mostly flat, no big moves reported.
Overall: Pause in big buying after strong prior months. Companies building cash instead.
USDT's U.S. Market Access Hinges on 2028 GENIUS Deadline
Tether's USDT is now on a two-year countdown to meet GENIUS Act requirements or risk losing eligibility for listing on U.S. centralized exchanges.
The foreign stablecoin issuers like Tether may have until July 2028 to comply with the law, which could require OCC registration, adherence to U.S. freeze-and-seizure orders, and changes to USDT's reserve composition.
The GENIUS Act, signed into law a year ago, mandates that stablecoin issuers be fully backed by highly liquid assets — essentially cash and U.S. Treasuries. Tether's latest disclosures show roughly a quarter of USDT's reserves are still tied up in assets that wouldn't meet that standard, including precious metals, lending positions, and bitcoin holdings.
Galaxy Launches a Bitcoin Quantum Initiative
Galaxy Digital has launched a Bitcoin Quantum Readiness Initiative to defend Bitcoin’s cryptography against the long-term threat posed by quantum computers.
The program pairs up to $5M in developer grants for post-quantum solutions with a Quantum Advisory Council, plus a research and publishing track run by Galaxy Research.
Ramp Launches Stablecoin Accounts for Business
Corporate-finance platform Ramp has launched Stablecoin Accounts, letting its 50,000+ business customers hold USDC and USDT, make cross-border payments and earn rewards — all without leaving Ramp.
Businesses can move USDC and USDT 24/7 with no USD on- or off-ramp fees, and earn up to 3.25% in rewards on balances. Ramp is clear these are activity-based payouts, not interest or investment yield. The core pitch is cross-border payments: a standard wire costs $35-$75 and takes one to three days, whereas stablecoins clear in a matter of seconds — and Ramp already moves ~$100B a year.
Telegram plans to Launch a Native Gram Wallet
Pavel Durov says Telegram will build a native, non-custodial Gram wallet into every version of the app this summer, bringing instant, zero-fee crypto to its 1B+ users.
Durov calls it the largest non-custodial wallet deployment in history. It supports Gram — Telegram’s native token, rebranded from Toncoin in June — and keeps users in full control of their keys, secured by two-factor authentication on their Telegram account.
Movement Labs Files for Chapter 11
Movement Labs, the developer behind the MOVE blockchain, has filed for Chapter 11 bankruptcy — months after a market-making scandal and a strategic overhaul gutted the project.
The filing lists under 1,000 creditors, $100K–$500K in assets and over $1M in liabilities under a Subchapter V small-business restructuring. It caps a fall from a ~$3B valuation, with MOVE down roughly 99%. The 2025 scandal saw a market-making deal dump 66M MOVE, crashing the price and prompting a Coinbase suspension. CEO Torab Torabi says separate entity Move Industries keeps running the network normally.
Augustus Raises $180M Series B at $1B Valuation
Augustus has secured $180 million in a Series B round, reaching a $1 billion valuation, to expand its mission of providing financial institutions worldwide with programmable access to U.S. dollar accounts and payment rails.
The round was led by Tiger Global, with participation from QED Investors, Hummingbird VC, Brevan Howard Digital, existing backers, and founders of Ramp, Deel, Nubank, and Circle.
Jack Mallers Steps Down as CEO of Twenty One Capital, Raphael Zagury Takes Over
Jack Mallers has stepped down as CEO of Twenty One Capital (NYSE: XXI), effective immediately, to focus full-time on Strike, the Bitcoin payments company he founded. Board member Raphael Zagury, CEO of Elektron Energy, has been named as his successor.
The leadership change comes alongside the collapse of a proposed three-way merger between Twenty One Capital, Strike, and Elektron Energy, first floated by Tether in April. Strike will remain an independent company, while a potential two-way combination between Twenty One and Elektron remains under preliminary evaluation.
Falcon Finance Launches Falcon Card for Real-World Crypto Spending

Fluidstack has Closed an $830M Series A Funding
Fluidstack has closed an $830M Series A at a $7.5B valuation, led by Situational Awareness — the AGI-focused fund from ex-OpenAI researcher Leopold Aschenbrenner. The company builds compute infrastructure for the world’s leading AI labs, aiming to be the fastest on the planet at deploying hundreds of gigawatts of compute.
Fluidstack said the raise came “with participation from world-leading investors” but named only the lead. Bloomberg earlier reported the round’s backers include Stripe’s Collison brothers, ex-GitHub CEO Nat Friedman and AI investor Daniel Gross, with Google also weighing a stake; Goldman Sachs advised on the deal.
Bybit Acquires NOBI to Enter Indonesian Market
Bybit has acquired a majority stake in Indonesian crypto exchange NOBI, rebranding it as Bybit Indonesia and launching a locally regulated platform under OJK supervision.
The world’s #2 exchange by volume enters a market of 21M+ registered crypto users, rolling out in phases from 500+ trading pairs. It is led by ex-NOBI executives Lawrence Samantha (CEO) and Dionisius Evan (COO). The deal fits Bybit’s regulatory-first playbook of entering new markets through licensed local entities — Indonesia saw roughly $26.85B in crypto transactions in 2025.
Wanchain’s Cardano Bridge Drained of 515M NIGHT (~$9M)
Wanchain’s Cardano bridge was drained of ~515M NIGHT — roughly $9M — from its treasury, in an exploit flagged by BlockSec’s Phalcon. NIGHT is the token of Midnight, the privacy chain from Cardano’s Input Output.
The root cause was a signature-reuse flaw: the TreasuryCheck validator hashed 14 raw-concatenated fields with no delimiters, so a legit BSC signature authorizing ~3,110 NIGHT was replayed on Cardano to extract 203M NIGHT — a ~65,000x inflation. NIGHT crashed over 30% intraday to a record low near $0.016. Phalcon says CBOR-encoded field boundaries would have blocked this field-splitting signature reuse.

Databricks Hits $188B Valuation in Latest Funding Round
Databricks announced a new funding round Thursday valuing the company at $188 billion, led by Coatue. The valuation jump caps an aggressive 18-month run: $10B raised at a $62B valuation in Dec 2024, $1B at $100B in Sep 2025, $5B at $134B in Feb 2026, and now this latest round at $188B.
Founded in 2013 as a big-data analytics platform, Databricks has repositioned as core AI infrastructure, rolling out products like Lakebase, Unity, and Omnigent on top of its existing enterprise data holdings.
MetaMask Catches North Korea-Linked Consultant in Core Code Work
Consensys, the firm behind the MetaMask wallet, unknowingly hired a software developer with alleged ties to North Korea, who spent roughly a month working on core platform code before being terminated.
The individual used the alias "Tyler Knapp" and GitHub handle "imyugioh", was brought on as a consultant through an existing third-party service provider relationship. He contributed to core MetaMask code, including components for crypto-to-fiat conversion via third-party payment providers and parts of the mobile wallet platform. His contributions began March 9 and stopped abruptly in April 2026, coinciding with the termination of his access.
Notably, the same GitHub identity had prior contributions to several other crypto projects, including Ankr, Blueberry Protocol, DEPO, Pickle Finance, and Harmony.
Binance & Bybit See $2.3B in Stablecoin Outflows Over 30 Days
Stablecoin reserves on two of the largest exchanges have dropped sharply, pointing to shrinking liquidity as BTC remains stuck near key support.
According to CryptoQuant analyst Darkfost, Binance's stablecoin reserves fell by roughly $1.55 billion over the past 30 days, while Bybit saw approximately $786 million in outflows, bringing the combined decline to nearly $2.3 billion across both platforms. The exact destination of these funds remains unconfirmed, though possible factors include MiCA-related user migration in Europe, weaker fresh capital inflows, and stablecoins moving into self-custody or onchain yield products.
Vitalik Demos an Anonymous Message Board on Aztec
Ethereum co-founder Vitalik Buterin has shared a “vibe-coded” demo of an anonymous message board built on Aztec, Ethereum’s ZK privacy L2. Users deposit ETH on mainnet, post anonymously on L2 with no public link between a post and their wallet, and can withdraw later.
The twist is onchain moderation: a designated censor can flag posts as “immoral” — hiding them from default feeds and time-locking the poster’s next messages — while a local LLM daemon checks each post against a transparent onchain policy. Posts are rate-limited by deposit size (0.001 ETH = 1 post/hour), and the logic ships with 70 theorems formally proven in Lean 4. Based on his 2022 “anon billboard” blog idea, Buterin stressed the demo is early, incomplete and only a toy — with access-control fixes and browser flows still to do.
