POLYHEDRA BLAMES LIQUIDITY ATTACKS FOR DROP IN TOKEN PRICE, RELEASES BUYBACK PLAN: Polyhedra, a crypto protocol, announced a buyback plan to restore trust after its token, ZKJ, plummeted over 80% in minutes. An initial post‑mortem released in Asian morning hours laid out various factors resulting in the collapse, including a supposed coordinated liquidity attack on PancakeSwap’s ZKJ/KOGE pool, substantial ZKJ deposits by market-making company Wintermute into centralized exchanges, and a cascade of liquidations on CEXs like Bybit. On-chain data reveals that several addresses had drained millions from the ZKJ/KOGE pool. One removed about $4.3 million in liquidity provider (LP) tokens and dumped 1.57 million ZKJ; others followed, unloading close to 1 million ZKJ each. When the shallow KOGE/USDT pool couldn’t absorb the sell pressure, activity spilled over into the deeper ZKJ/USDT pool, triggering a liquidity spiral, the team claimed. To stem the hemorrhage, Polyhedra’s team injected approximately $30 million in USDT, USDC, and BNB as DEX liquidity. It added that no ZKJ holdings belonging to the team were sold. Polyhedra affirms it’s conducting a full technical investigation, and its upcoming buyback initiative aims to both offset the attack’s impact and deter similar future exploits. — Shaurya Malwa Read more.

OPTALYSYS DEBUTS SERVERS FOR BLOCKCHAINS: Optalysys, a U.K.-based startup focused on secure computing, has introduced what it claims to be the world’s first server for blockchains that can process data at scale without decrypting it. The firm’s LightLocker node is a server that uses Fully Homomorphic Encryption (FHE), a mathematical technique allowing computations to be performed on encrypted data without compromising the encryption. The last year has seen a couple of firms raising money and exploring applications of FHE within the cryptocurrency space. Optalysys says its server hardware is purpose-built for blockchain encryption, and offers a cheaper alternative to costly and inefficient GPU-based systems, using 40% less energy. — Ian Allison Read more.

INK FOUNDATION TO AIRDROP TOKEN: The Ink Foundation, the nonprofit behind layer 2 Ink, is launching its native token INK in an attempt to bootstrap on-chain capital markets through a liquidity-first strategy. The token will debut on a decentralized finance (DeFi) lending and trading protocol built on Aave, and distribution will begin via an airdrop to early users. There will be no governance gimmicks or fluctuating emissions schedules, the foundation said. INK has a hard cap of 1 billion tokens minted, with no recourse to change the supply via governance proposals. And unlike other Superchain members, Ink says its layer 2 governance will remain separate from the token. — Shaurya Malwa Read more.

U.S. banking giant JPMorgan has announced the pilot of a permissioned USD deposit token called JPMD on Base, the layer 2 Ethereum network built by listed exchange Coinbase (COIN).

Iranian crypto exchange Nobitex has been hacked for $90 million by Israel-linked hacking activist group Gonjeshke Darande, according to a blog post from blockchain security firm Elliptic. The group said in an X post: “After Bank Sepah, it was Nobitex’s turn,” referencing their Tuesday cyberattack on Iran’s state-owned lender. They warned that Nobitex’s internal data and source code would be released within a day, and any assets left on the exchange would be “at risk.” — Shaurya Malwa Read more.

Regulatory and Policy

The overwhelming bipartisan passage of the U.S. Senate’s stablecoin bill, with a 68-30 final vote that saw a huge surge of Democrats joining their Republican counterparts on Tuesday, sets a new high-water mark of crypto policy efforts in the U.S. as the legislation now heads to the House of Representatives. The major Democratic backing for the Guiding and Establishing National Innovation for U.S. Stablecoins of 2025 (GENIUS) Act helps give it momentum as it lands in the other chamber, where House lawmakers can either vote on it as written or pursue changes that will require a final round in the Senate before it can head to President Donald Trump’s desk. — Jesse Hamilton Read more.

Crypto Trading Firm Keyrock Buys Luxembourg’s Turing Capital in Asset Management Push

Crypto trading firm Keyrock said it’s expanding into asset and wealth management by acquiring Turing Capital, a Luxembourg-registered alternative investment fund manager.

The deal, announced on Tuesday, marks the launch of Keyrock’s Asset and Wealth Management division, a new business unit dedicated to institutional clients and private investors.

Keyrock, founded in Brussels, Belgium and best known for its work in market making, options and OTC trading, said it will fold Turing Capital’s investment strategies and Luxembourg fund management structure into its wider platform. The division will be led by Turing Capital co-founder Jorge Schnura, who joins Keyrock’s executive committee as president of the unit.

The company said the expansion will allow it to provide services across the full lifecycle of digital assets, from liquidity provision to long-term investment strategies. «In the near future, all assets will live onchain,» Schnura said, noting that the merger positions the group to capture opportunities as traditional financial products migrate to blockchain rails.

Keyrock has also applied for regulatory approval under the EU’s crypto framework MiCA through a filing with Liechtenstein’s financial regulator. If approved, the firm plans to offer portfolio management and advisory services, aiming to compete directly with traditional asset managers as well as crypto-native players.

«Today’s launch sets the stage for our longer-term ambition: bringing asset management on-chain in a way that truly meets institutional standards,» Keyrock CSO Juan David Mendieta said in a statement.

Gemini Shares Slide 6%, Extending Post-IPO Slump to 24%

Gemini Space Station (GEMI), the crypto exchange founded by Cameron and Tyler Winklevoss, has seen its shares tumble by more than 20% since listing on the Nasdaq last Friday.

The stock is down around 6% on Tuesday, trading at $30.42, and has dropped nearly 24% over the past week. The sharp decline follows an initial surge after the company raised $425 million in its IPO, pricing shares at $28 and valuing the firm at $3.3 billion before trading began.

On its first day, GEMI spiked to $45.89 before closing at $32 — a 14% premium to its offer price. But since hitting that high, shares have plunged more than 34%, erasing most of the early enthusiasm from public market investors.

The broader crypto equity market has remained more stable. Coinbase (COIN), the largest U.S. crypto exchange, is flat over the past week. Robinhood (HOOD), which derives part of its revenue from crypto, is down 3%. Token issuer Circle (CRCL), on the other hand, is up 13% over the same period.

Part of the pressure on Gemini’s stock may stem from its financials. The company posted a $283 million net loss in the first half of 2025, following a $159 million loss in all of 2024. Despite raising fresh capital, the numbers suggest the business is still far from turning a profit.

Compass Point analyst Ed Engel noted that GEMI is currently trading at 26 times its annualized first-half revenue. That multiple — often used to gauge whether a stock is expensive — means investors are paying 26 dollars for every dollar the company is expected to generate in sales this year. For a loss-making company in a volatile sector, that’s a steep price, and could be fueling investor skepticism.
