EU-Regulated Exchange 21X Integrates Chainlink Data

TheCryptoTimesPublished on 2025-09-15Last updated on 2025-09-15

21X, the first European Union-regulated exchange for on-chain tokenized securities, has integrated Chainlink to provide verifiable market data for its listed assets on the public Polygon blockchain, a move aimed at enhancing transparency for institutional participants. The Frankfurt-based bank will use the oracle tool to make trading data available in real time on the public Polygon blockchain. This is done to make things more clear for institutional participants.

The integration went live following a September 15, 2025  announcement, just a week after 21X officially opened its regulated trading venue on September 8. It will publish crucial data points, including best bid and ask prices, their corresponding quantities, and the last traded prices for 21X’s tokenized securities. 

This process is powered by the Chainlink Runtime Environment (CRE), which automatically retrieves data from on-chain contracts, aggregates it, and publishes it in a standardized format for DeFi applications to consume.

A New Standard for Onchain Finance

This new development builds on a strategic relationship that was first announced on December 2, 2024, mixing both digital and traditional infrastructure Max Heinzle, CEO of 21X, said that the integration gives big clients the openness and auditability they need. 

“The Chainlink standard enables 21X to securely and reliably bring real-time, verifiable market data for tokenized securities onchain,” Heinzle stated. “By integrating Chainlink into our regulated DLT trading venue, we’re delivering the transparency, auditability, and collateral utility that institutions require to move onchain.”

The partnership could open up new, more complex ways to use controlled digital assets. These tokenized securities can be used as collateral in decentralized finance (DeFi) loan protocols and built into automated portfolio management strategies because they make data that can be checked easy to find. 

CEO of Chainlink Labs and President of Banking & Capital Markets, Fernando Vazquez said the combination was a “key moment for the blockchain economy.” He added that making EU-regulated securities more usable across DeFi “opens the floodgates of institutional capital to flow onchain.”

This integration is a big step toward connecting the onchain economy to regular capital markets. By putting clear, dependable, and checkable data about regulated financial instruments on a public blockchain, 21X and Chainlink are creating important infrastructure that could speed up the acceptance of DeFi by institutions. This movement shows, by many use cases, that blockchain technology combined with traditional ways of doing finance are now trending and can show a path to the next steps.

Anthropic Employees Leave to Start a Business, Valued at $1 Billion, Also Focused on 'Recursive Self-Improvement'

Former Anthropic employees Behnam Neyshabur and Harsh Mehta have founded a startup named Mirendil, securing $200 million in seed funding at a $1 billion valuation from investors including Andreessen Horowitz, Kleiner Perkins, and NVIDIA. The company, staffed by researchers from Anthropic, xAI, Google DeepMind, and OpenAI, aims to accelerate scientific discovery by focusing on "recursive self-improvement" for AI. Their vision, described as "AI for AI for Science," is to build a platform enabling research labs in fields like medicine and materials science to develop and iteratively improve their own specialized AI models, rather than relying on general-purpose models from large tech firms. Neyshabur argues this approach, involving AI that can optimize its own code under human supervision, is the fastest path to AI-accelerated science. The founders believe a market opportunity exists because major AI companies, while increasingly using AI to advance their own research, restrict external developers from using their models to train competing products. Mirendil plans to release its first models soon to gather early user feedback, with the goal of empowering thousands of labs to tackle critical scientific challenges.

Trillion-Dollar Pension Fund Entry? Franklin Bitcoin Dividend Reinvestment ETF Comes with a Built-in Selling Pressure Ceiling

Franklin Templeton has filed to launch two ETFs that embed a "default configuration" logic into Bitcoin investment, aiming to tap into massive pension fund flows. These "Bitcoin Dividend Reinvestment Index ETFs" will initially hold 95% equities and 5% Bitcoin, automatically reinvesting stock dividends to buy Bitcoin. However, a quarterly rebalancing rule forces selling of Bitcoin if its allocation exceeds 5%, capping its maximum holding at 20%. While the product cleverly circumvents advisor reluctance and compliance hurdles by labeling itself as a U.S. equity product, its actual Bitcoin buying power is minimal. Given low dividend yields (e.g., ~1% for broad market indices), annual Bitcoin purchases from a fund the size of Franklin's existing Bitcoin ETF would be a mere $3.6 million—negligible against Bitcoin's daily trading volume. Crucially, during bull markets, the fund becomes a programmed, passive *seller* of Bitcoin, potentially creating sustained sell pressure if many similar funds emerge. The strategy leverages investor inertia and automatic enrollment, similar to the success of target-date funds in 401(k) plans. It also uses an offshore Cayman subsidiary for holding Bitcoin and raises a tax complication where investors must pay taxes on dividends they never receive as cash. Although recent U.S. regulatory changes allow crypto in retirement plans, widespread adoption as a default option faces legal hurdles. The core premise remains: the system doesn't need to convince anyone to buy Bitcoin actively; it simply relies on people doing nothing.

Bitcoin Hits 20-Month Low as Largest Bull Suffers $15 Billion Paper Loss

Bitcoin Hits 20-Month Low as Major Bull Loses $15 Billion On June 25th, Bitcoin fell below $60,000, hitting a low of $58,030—its lowest level since October 2024. The sell-off triggered over $1 billion in leveraged liquidations in 24 hours, with longs accounting for $788 million. This marks a more than 53% decline from the October 2025 all-time high of $126,198. A critical factor in the downturn is the weakening position of MicroStrategy, the largest corporate Bitcoin holder. With 847,363 BTC at an average cost of $75,651, the company now faces over $14.6 billion in unrealized losses. Its core financing flywheel—raising capital to buy Bitcoin—is stalling. Its variable-rate preferred shares (STRC), a key fundraising tool, have fallen 25% below their $100 target. This raises doubts about its ability to continue providing steady institutional demand for Bitcoin. Simultaneously, U.S. spot Bitcoin ETFs are experiencing significant outflows, with a single-day net outflow of $469 million on June 24th. This represents the most severe sustained capital flight since their launch. The macroeconomic backdrop remains restrictive, with persistent inflation delaying expected Fed rate cuts. Analysts note a shift in capital allocation, with institutional funds moving away from crypto towards AI infrastructure stocks. Immediate pressure comes from approximately $10 billion worth of Bitcoin options expiring on June 26th, which could increase market volatility. The combined effect of these factors—eroding core demand pillars, macro headwinds, and capital rotation—has decisively broken the $60,000 support level.

STRC Falls Below $80, Can Conservative Investors Still Buy the Dip?

The article analyzes whether the STRC (a perpetual preferred stock issued by MicroStrategy) presents a buying opportunity after its price fell below its $100 par value to around $80, offering a seemingly high yield of 13-15%. The core argument is that STRC's discount reflects market skepticism about the sustainability of MicroStrategy's capital structure model, not just temporary panic. This model relies on issuing securities (like STRC) to raise funds to buy more Bitcoin, a "flywheel" that works in a bull market. The recent small sale of BTC to fund dividends, while minor, broke the psychological "never sell" anchor and signaled potential strain. Key risks identified are not a traditional Ponzi collapse but a potential breakdown in the financing narrative: 1) If Bitcoin enters a deep bear market, crushing MicroStrategy's stock premium (mNAV), its ability to raise cheap capital weakens. 2) If STRC remains deeply discounted, it signifies permanently higher funding costs. 3) The high cash dividend yield represents a significant ongoing expense. 4) If selling BTC to pay dividends becomes routine, the bullish narrative reverses. The conclusion is that STRC is not a risk-free high-yield asset. It is a high-coupon bet on whether MicroStrategy's BTC treasury financing model can withstand a bear market. Buying it is a wager that the market will continue to believe in and fund this structure at acceptable costs. The current price asks if this cycle's "casualty" might be a BTC treasury company's融资 model itself.

Why Do Crypto Projects Keep Changing Their Names?

**Why Do Crypto Projects Keep Changing Names?** In the crypto world, changing a project's name is common—over 16% of projects have done so, including major ones like Polygon (formerly Matic Network). This contrasts sharply with traditional businesses, which fiercely protect brand equity. The core reason is that in crypto, brand loyalty is often weak. Users are frequently investors, airdrop hunters, or yield seekers, not traditional consumers. A name associated with price crashes, hacks, or failed narratives becomes a liability, not an asset. Renaming can be a strategic reset to shed this baggage. Name changes serve as a potent marketing tool. They can signal a genuine pivot in strategy or scope (e.g., EthSign dropping "Eth" as it expanded). However, they are often used to "narrative surf," rebranding to align with hot trends like AI, RWA, or the metaverse (e.g., Elrond → MultiversX). Critically, renaming is also a PR tactic to distance a project from past failures like security breaches (e.g., Anyswap → Multichain). The most significant risk emerges when a name change is coupled with a token migration or swap. This process can allow projects to reset exchange price charts, erase visible historical downtrends, and create an illusion of a fresh start. It often facilitates liquidity resets, where low float can be exploited for pumps. More alarmingly, migrations sometimes mask overhauls to tokenomics, introducing substantial new token supply through "ecosystem funds" or "node rewards," effectively diluting existing holders. The fundamental issue isn't renaming itself, which can be valid for strategic evolution. The problem is when it functions as an escape from history—a way to avoid accountability for past mistakes, failed promises, and poor performance. When a project announces a rebrand, the critical questions are: What tangible new capability or strategy does it represent? Has the tokenomics changed? And what part of its past is it most trying to make users forget?
