LayerZero (ZRO), together with Citadel Securities and DTCC, will launch the institutional crypto exchange ATLAS this fall. 25 Aug, 2026 byDropsTab Join Its Socials ATLAS will not have a consumer application; it will become the underlying infrastructure for trading assets on the blockchain for institutional clients. Coinbase has launched tokenized stocks on Base. Trading is available 24/7, and liquidity has already appeared on Aerodrome (AERO). 25 Aug, 2026 byDropsTab Join Its Socials Coinbase has launched tokenized shares of U.S. companies on the Base network. These shares are issued under the B20 standard and are backed by real shares held in a 1:1 ratio by the regulated broker and custodian Alpaca. Users outside the U.S. in supported jurisdictions will be able to hold and trade fractional shares of stocks, including Apple and NVIDIA, directly through non-custodial wallets. Trading is available 24/7, and liquidity has already appeared on Aerodrome. The tokenized shares can also be used in Base's DeFi protocols - for example, as collateral for loans via Aave or to provide liquidity on DEXs. B20 is based on ERC-20 and is compatible with existing wallets and DeFi infrastructure. Dividends and stock splits are accounted for via a special on-chain mechanism without changing the number of tokens on the balance. Base announced that in the coming weeks, Coinbase's list of available tokenized shares will be expanded, and later, other RWA assets are planned to be added to the network. Arthur hayes' new essay, "same same but different": Bessent repeats Yellen's pattern - Bitcoin responds with a rise. 25 Aug, 2026 byDropsTab Join Its Socials The actions of the U.S. Treasury Department, led by Scott Bessent, are starting to resemble Janet Yellen's policy from late 2023, when an increase in short-term government bond issuance helped release about $2.4 trillion in liquidity. It was precisely this factor that supported the growth of Nasdaq and Bitcoin at the time. Now, Bessent is trying to curb the rise in long-term Treasury yields by increasing the volume of reverse repurchase agreements. On August 19, the Treasury announced additional buybacks totaling approximately $20 billion, after which the yield on 10-year bonds briefly declined, and Bitcoin saw a noticeable rally. However, this volume is insufficient, and the market may force the Treasury to expand its support. Three possible scenarios: * The Treasury and the White House cut spending - unlikely ahead of the election; * Bessent announces unlimited bond buybacks at yields above 5% (following the model of the Bank of Japan) - the best-case scenario for Bitcoin; * The most likely scenario is a gradual increase in buybacks combined with the use of other reserves, including the Treasury's account at the Federal Reserve (TGA, around $1 trillion). A direct interest rate cut or a new round of quantitative easing is unlikely until the AI infrastructure market bubble bursts. Maelstrom's position: The company holds maximum risk in its portfolio - betting on Bitcoin, Ether, Ethena, and Ether.fi. Mining Zcash (ZEC) is currently 4.5 times more profitable than mining Bitcoin (BTC). 24 Aug, 2026 byDropsTab Join Its Socials Against the backdrop of ZEC's growth, the profitability of Zcash mining has noticeably increased. Currently, the Antminer Z15 Pro generates about $727 in gross revenue per 1 MWh of electricity: * Zcash - $727 per 1 MWh. * AI/HPC computing - $223. * Bitcoin on the Antminer S23 Pro - $162. * Bitcoin on the Antminer S21 Pro - $103. In terms of gross revenue per unit of electricity, Zcash mining is now approximately 3.3 times more profitable than AI/HPC and 4.5 times more profitable than Bitcoin mining on the new-generation ASICs. As recently as late June, the Z15 Pro generated around $373 per 1 MWh. The main driver behind this increase was the rise in ZEC prices by roughly 70% over the past week. It's important to note that this refers specifically to gross revenue, excluding costs for equipment, maintenance, and electricity consumption. The Entropy platform for trading pre-IPO assets on Hyperliquid has raised $14 million and $40 million in HYPE. 24 Aug, 2026 byDropsTab Join Its Socials The Entropy project has announced the raising of $14 million in funding led by Ribbit Capital, as well as $40 million in HYPE, which will be staked to develop trading markets on Hyperliquid. Entropy's first product will be a marketplace for trading Anthropic - the team calls it the first liquid way to gain exposure to the company before its IPO. Entropy is developing infrastructure for trading assets that are difficult to bring onto conventional markets: pre-IPO companies, startups, commodities, indices, and other instruments. To this end, the project is building its own liquidity-weighted oracle that will take into account the real depth of the market and enable price discovery directly through the order book. The team consists of former employees and traders from Citadel Securities, Optiver, Polymarket, and Millennium. The project's first markets are already being launched on Hyperliquid.

Wintermute has obtained a brokerage license in the U.S. 06 Aug, 2026 byDropsTab Join Its Socials Wintermute has registered its U.S. office as a broker-dealer, obtaining oversight from FINRA and the SEC. This paves the way for the company to obtain official market-maker status on the NYSE and Nasdaq exchanges. It will start with crypto-related markets - commodities and digital asset ETFs - and then plans to enter the tokenized equity space if regulatory conditions permit. Wintermute USA has already attracted ETF issuers as clients and expects to compete with Jump Trading, Jane Street, and Citadel Securities within 3-5 years. Upbit will list Kamino (KMNO). 06 Aug, 2026 byDropsTab Join Its Socials Kamino - a landing protocol on Solana +30% in real time Voting on the CLARITY Act postponed until September. 06 Aug, 2026 byDropsTab Join Its Socials Senate Republicans will head into the August recess without voting on the CLARITY Act - legislation review is being postponed until at least September, Politico reports. Senate Majority Leader John Thune confirmed that the chamber is "delaying" the vote. The reason is insufficient support from Democrats, which is necessary to advance the bill. Negotiations are ongoing. Thune could seek cloture before the recess - a procedural move that would allow the vote to be scheduled for when senators return in mid-September; however, the actual vote on the bill would still not take place. Democrats refused to approve a time agreement that would have accelerated remaining business before the recess and brought the crypto legislation to a vote. To wrap up work without dragging the session into next week, Republicans would need unanimous consent from all 100 senators. Upbit and Bithumb will list BSB. 06 Aug, 2026 byDropsTab Join Its Socials Block Street - DeFi protocol for RWA and stocks up 24% at the moment Robinhood lists CASHCAT. 06 Aug, 2026 byDropsTab Join Its Socials Cash Cat is a popular meme coin created by the community on the Robinhood Chain blockchain. +48% to the price amid the news Meta's AI model (banned in the Russian Federation) hacked someone else's system during cybersecurity testing. 06 Aug, 2026 byDropsTab Join Its Socials The company reported that one of its AI models, during testing, hacked into another company's system due to a configuration error in the evaluation environment. According to Reuters, the model gained internet access due to improper configuration and then exploited a vulnerability in a third-party service. The model in question may have been Muse Spark 1.1, which Meta positions as one of its most advanced models for programming and agent-based tasks. Meta emphasized that the incident occurred during controlled testing, not as a result of an actual cyberattack. Previously, similar incidents have been linked to models from other companies, including Anthropic and OpenAI.

Citadel Securities hired a semiconductor architect and Goldman Sachs MD. 3 hours ago Semiconductor stocks may have hit a rough patch last month, but the talent working on that technology is as in-demand as ever. Electronic market maker Citadel Securities recently hired the former CTO of a smaller semiconductor design firm, who was most recently plying his trade at Goldman Sachs. Mayan Moudgill joined Citadel Securities last month in New York as a senior software engineer. He spent the last quarter century working across Goldman Sachs and Sandbridge Technologies, a semiconductor manufacturing firm. He spent the last five years at Goldman Sachs, where he was an MD within the bank's engineering division, but spent seven years before that as chief architect and CTO of Sandbridge. Moudgill was part of the Sandbridge founding team in 2001, and became a tech fellow at Goldman Sachs during his first stint there. Moudgill is also credited on over 100 patent filings dating back to 1996. Many of these involve multithreading, where different threads of a program can run concurrently on different cores of a piece of hardware, allowing for significantly faster data analysis. His later patents, filed during his time at Sandbridge (which had changed names to Optimum Semiconductor Technologies after being acquired by a Chinese technology firm), were for a "neural network accellerator." Although Moudgill is joining as a software engineer, it seems likely that he will be working on hardware in some capacity. Citadel Securities declined to comment further than verifying his job title. It has a robust hardware engineering team which primarily works on Field Programmable Gate Arrays (FPGAs). It offers base salaries of up to $350k for FPGA engineers in current open job listings.

ICYMI fintech funding round-up: Curant.ai, Oloman, Beelzebub, and more. A handy round-up of the recent funding endeavours of fintech companies across the globe. July 31, 2026 At FinTech Futures, we know that it can be easy to let funding announcements slip you by in this fast-paced industry. That's why we put together our weekly In Case You Missed It (ICYMI) funding round-up so you can get the latest funding news. Epic Markets bags $10m pre-seed ahead of market rollout. Fintech start-up Epic Markets has raised $10 million in pre-seed funding from sole investor Karatage to develop its multi-asset brokerage platform for retail investors. Founded in 2026 by former Citadel Securities executives Kevin Kimmel and Brian Seegers, the Epic Markets platform is being built to "deliver institutional grade trading tools and liquidity to retail traders", according to LinkedIn. In a company statement, Epic Markets says it will use the new funds from Karatage to "accelerate the development of the platform and strengthen its technology offering ahead of its market rollout". Epic Markets is now encouraging customers to sign up to a waitlist via its website. FNG, which broke news of the raise, reports that a platform rollout could happen as soon as this year, targeting retail investors in the US and UAE. Birdai Labs secures $4m to develop blockchain infrastructure. US-based fintech Birdai Labs has raised $4 million in seed funding led by Castle Island Ventures, with support from Metalayer Ventures and The Venture Dept. Birdai operates base-layer infrastructure that measures and analyses blockchain transactions to show traders how much money they lose to hidden fees and price changes between placing an order and completing a trade. With the capital, founders Greg Scanlon and Kevin Farrelly now plan to "fund senior engineering hires and extend the company's infrastructure at the base of the chain", according to the seed funding announcement. Farrelly, who leads Birdai as CEO, previously founded machine-learning credit company Random Forest Capital in 2016, before selling to Franklin Templeton two years later. He joined the investment manager as a managing principal through the purchase, and spent the next seven years building blockchain venture funds. It was during this tenure that Farrelly met Scanlon, who used to work as a senior quantitative trader at Citadel before he joined Franklin Templeton in 2022. Beelzebub total funding tops €3.3m with new seed fundraise. Beelzebub has raised €3 million in a seed funding round led by United Ventures. The raise adds to a previously undisclosed €300,000 pre-seed round, and brings the Italian cybersecurity firm's total funding since inception to €3.3 million. Breaking the funding announcement on LinkedIn, CEO and founder Mario Candela reflects on the company's journey: "Five years ago I started writing Beelzebub on weekends as an open-source project." Since then, the firm has grown its offering into three flagship products: Arcangelo, Beelzebub Cloud, and Caronte. Candela explains: "Arcangelo continuously simulates a real attacker against the live perimeter. Beelzebub Cloud deploys deception infrastructure that is indistinguishable from production systems, so lateral movement is detected the moment it happens. Caronte reconstructs the attack and produces an incident report in minutes instead of weeks." A newsletter from United Ventures states that, with the funds, Beelzebub "is assembling a research team around Mario, including experienced vulnerability researchers, and will open commercial offices in Rome and San Francisco by the end of 2026". US insurtech Curant.ai lands $3.1m seed round. Curant.ai, a Utah-based AI software company that aims to automate the claims process for insurance organisations, has raised $3.1 million in a seed funding round led by early-stage investment firm Diagram. Other participants in the round included Humania Insurance, Element Ventures, Blue Plains Capital, and various angel investors. The insurtech was founded by CEO John Haller this year. Haller previously co-created beatBread in 2019 as a music funding platform which is now backed by Citigroup, Deciens Capital, and Mucker Capital. His latest venture develops AI software that extracts data from documents to help insurance staff review and process claims faster. Curant.ai says it will use the funding to develop its platform, "starting with a solution dedicated to disability". Fincart prepares for international expansion following $2.8m seed raise. Egyptian fintech Fincart has secured $2.8 million in seed funding. The oversubscribed round was co-led by Launch Africa and Antler MENAP, with Yango Ventures, Five35 Ventures, Bluestream Capital, Hi2 Global, and Kalahari Venture Labs also participating. Founded in 2023 by Mostafa Masry and Nihal Ali, Fincart provides an AI-powered operating platform which enables merchants to manage shipping, customer engagement, and cash advances through one interface. Since launch, the platform has grown to serve over 450 clients and is integrated with more than 40 courier companies across Africa. Fincart states that the new capital will lay the foundation for international expansion in 2027, and will be used to "scale its commercial and tech teams, invest in product development, and forge new commercial partnerships to strengthen its position in its home market". Olomon targets general availability with $2.6m pre-seed round. US-based fintech Olomon has scored $2.6 million in an oversubscribed pre-seed round backed by "entrepreneurs, fintech investors, and financial-services professionals, a number of whom are users of the product themselves", according to a company statement. Founded in 2023 by Jeremy Bolls, Olomon provides a client-owned financial system of record that consolidates household accounts, entities, documents, contacts, and decisions with permissioned access for advisors. In a blog post announcing the company's latest funding round, Bolls outlined the three priorities for the company's development roadmap. First, the platform is expanding its product depth to comprehensively track household portfolios, including private investments, insurance, and estate structures, which early-access users are currently testing. Second, the company is strengthening its advisor infrastructure to ensure secure collaboration between clients, attorneys, CPAs, and financial advisors. Finally, the roadmap focuses on opening a clear pathway to general availability, transitioning away from the current invite-only phase to allow households and professionals to onboard directly without a waitlist. Reporter, FinTech Futures Francis Bignell is a reporter at FinTech Futures with a keen interest in all things fintech, especially in the Latin America region. Writing in the industry for four years, he has moderated webinars and podcasts as well as interviewed executives from a wide range of sectors.
