Network News
FUSAKA COMING THIS DECEMBER: Ethereum core developers have confirmed a tentative roadmap for the network’s next major upgrade, Fusaka, during an All Core Developers Consensus (ACDC) call. The upgrade, designed to further scale the blockchain, is now scheduled for early December, with follow-up changes aimed at more than doubling blob capacity in the weeks after. Before the Fusaka upgrade reaches Ethereum’s mainnet, developers will push the code through three public test networks in October. If those tests proceed smoothly, the mainnet activation is targeted for Dec. 3. Developers noted that exact epoch numbers and timing will be confirmed in the coming days. While Fusaka itself won’t immediately change blob parameters, the call outlined a phased approach to scaling blob availability through so-called Blob Parameter Only (BPO) forks. One week after Fusaka BPO-1 will raise the blog target/max from 6/9 to 10/15, then one week later BPO-2 will push the limit to 14/21. These incremental changes are based on performance observed on the Fusaka Devnet-5 and are intended to safely expand capacity without requiring client-side software updates. Blobs, introduced in March’s Dencun upgrade, allow Ethereum to store large amounts of rollup transaction data more efficiently, reducing costs for users of layer-2 scaling networks. — Oliver Knight Read more.
PLASMA BLOCKCHAIN FOR STABLECOINS COMING: Plasma, a new blockchain built specifically for stablecoins, is set to flip the switch on its long-awaited mainnet beta, introducing the chain and its native token, XPL, on Sept. 25. According to a blog post from the team, the network will debut with more than $2 billion in stablecoin liquidity from over a hundred partners on day one — an aggressive attempt to position Plasma not as just another general-purpose chain, but as the backbone for stablecoin transfers. That won’t be an easy feat. Ethereum and Solana already dominate stablecoin volumes, while newer chains continue to optimize for similar flows. Plasma’s bet is that its architecture, dubbed PlasmaBFT, will give it an edge. The system is designed for fast, composable stablecoin transactions the team said, and from launch, users will be able to move USDT with zero fees through Plasma’s dashboard — a feature the team hopes will stand out in a crowded DeFi landscape.Token distribution is also aimed at broad accessibility. Prior to launch, 10% of XPL was sold in a public offering. At launch, 25 million tokens will be allocated to the community, with another 2.5 million reserved for members of the so-called Stablecoin Collective.— Margaux Nijkerk Read more.
MIDAS AND INTEROP LAVS UNVEIL NEW LIQUID STAKING TOKEN: Real-world assets (RWA) focused project Midas and Interop Labs unveiled mXRP, an attempt to channel dormant XRP supply into yield-bearing structures the could deliver returns as high as 8%. Announced at XRPL Seoul 2025 on Monday and pitched as the first liquid-staking product tied directly to the XRP ecosystem, the product is minted on XRPL’s EVM through audited contracts. XRP is bridged in and wrapped under Midas’ tokenized certificate framework. MXRP can be used as a structured vehicle that users can slot into existing decentralized finance (DeFi) infrastructure, with early strategies including market-making and liquidity provisioning. Targeted net returns are set in the 6%–8% range, with outcomes fluctuating depending on underlying strategy performance.— Shaurya Malwa Read more.
ICP BETS BIG ON AI TECH STACK: The ICP, a blockchain project that has sought to differentiate itself from rivals, is doubling down on its pitch as the go-to network for on-chain artificial intelligence (AI). This could be the beginning of a new tech stack — one in which AI, not humans, becomes the primary developer of applications, according to Dominic Williams, founder of Internet Computer developer Dfinity. Williams argued that while crypto prices remain driven largely by market mechanics — treasury operations, liquidity games and speculation — the underlying technology will eventually force a reckoning in an interview with CoinDesk. “In the long run, markets begin to reflect realities on the ground,” he said. “But as yet you’re not seeing what’s happening with Internet Computer reflected in ICP’s price.” The Internet Computer first demonstrated neural networks running as smart contracts in April last year, starting with image classification and later facial recognition, Williams said. While those were relatively simple models compared to large language models — the kind that power AI tools like ChatGPT and Gemini — they were proof of concept: that AI can run natively on a blockchain. No other network has achieved this, Williams pointed out, despite the chatter about “decentralized AI.” Where others rely on off-chain infrastructure like Amazon Web Services, ICP seeks to integrate the full AI development and execution stack on-chain. Williams describes this as “a self-writing internet” — a system where users describe what they want, and an AI delivers it as a working application, hosted directly on Internet Computer. The bigger idea, Williams said, is that AI itself will replace much of today’s developer workflow. – Jamie Crawley Read more.

- Key metric tied to BlackRock’s Nasdaq-listed spot BTC exchange-traded fund, IBIT, has been flashing warning signs for two straight months. IBIT’s one-year put-call skew, a measure of market sentiment or pessimism, flipped positive on July 25 and has remained comfortably above zero since then, according to data source Market Chameleon. That’s two straight months of bearish put bias. In other words, traders have consistently favored protective puts over bullish calls for two months, signaling a sustained cautious or risk-averse outlook. A similar put option bias was observed from March 8 to April 21 this year, a period marked by sharp declines in both the spot price and IBIT, primarily driven by the trade war-induced weakness on Wall Street. — Omkar Godbole Read more.
- Bitcoin’s (BTC) break below key support has prompted a flurry of ‘buy the dip’ calls on social media. However, liquidity trends suggest a potential for a deeper decline. BTC has dropped over 3% to $111,590 this week, piercing the widely-tracked 50- and 100-day simple moving averages (SMA). Both indicators have lost their upward momentum for the first time since April, now flatlining to signal caution for bulls. Meanwhile, mentions of «buy the dip» on social media have surged to their highest level in nearly a month, a telltale sign of bullish sentiment among retail investors, according to data tracking platform Santiment. The platform tracks «buy the dip» mentions using its social trends indicator, which analyses the volume of relevant keywords and phrases across Reddit, Telegram and X (formerly Twitter). A spike in these mentions is considered a contrarian signal by Santiment, meaning the ongoing price pullback in BTC could deepen. — Omkar Godbole Read more.
Regulatory and Policy
- The U.S. Commodity Futures Trading Commission is starting an initiative to allow stablecoins as tokenized collateral to satisfy margin needs in the vast derivatives market, inviting input from the industry on how to bring such a policy online. In the latest move toward crypto inclusion in the U.S. financial sector, the acting chief of the CFTC, Caroline Pham, continues to advance policy in the absence of President Donald Trump’s current nominee to be the chairman, former Commissioner Brian Quintenz. As the confirmation process for Quintenz remains mired in delays and some open conflict, Pham has been regularly announcing initiatives as part of a «crypto sprint» and working with Securities and Exchange Commission Chairman Paul Atkins. «For years I have said that collateral management is the ‘killer app’ for stablecoins in markets,» Pham said in a statement. «I’m excited to announce the launch of this initiative to work closely with stakeholders to enable the use of tokenized collateral including stablecoins.» Pham had been pushing since last year for a so-called regulatory sandbox for tokenization, when she served as a commissioner during the previous administration, and when she took over as acting chairman, she announced the pursuit of a pilot program on stablecoin-backed tokenization. — Jesse Hamilton Read more.
- The U.S. Treasury Department is pushing forward with a narrow comment window on its preliminary, formal efforts to solidify the recently established stablecoin law into a set of regulations. This arm of President Donald Trump’s administration has opened what’s known as an «advance notice of proposed rulemaking», which is an early step taken to gather information that will be used to put together an actual proposal. In this case, the government is asking for data on building out its requirements under the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS) Act, including prohibitions on issuers, sanctions obligations, anti-money laundering compliance, the balance between state and federal oversight, tax matters and any further need from the industry for clarity. A one-month period is now open in which the public — and crypto businesses — can weigh in on these complex issues before it closes on October 20. The notice posted dozens of questions, such as, «Is additional clarity necessary regarding the extent to which reserve assets are required to, or should, be held in custody?» and «Are there foreign payment stablecoin regulatory or supervisory regimes, or regimes in development, that may be comparable to the regime established under the GENIUS Act?» — Jesse Hamilton Read more.

AAVE Sees 64% Flash Crash as DeFi Protocol Endures ‘Largest Stress Test’

The native token of Aave (AAVE), the largest decentralized crypto lending protocol, was caught in the middle of Friday’s crypto flash crash while the protocol proved resilient in a historic liquidation cascade.
The token, trading at around $270 earlier in Friday, nosedived as much as 64% later in the session to touch $100, the lowest level in 14 months. It then staged a rapid rebound to near $240, still down 10% over the past 24 hours.
Stani Kulechov, founder of Aave, described Friday’s event as the «largest stress test» ever for the protocol and its $75 billion lending infrastructure.
The platform enables investors to lend and borrow digital assets without conventional intermediaries, using innovative mechanisms such as flash loans. Despite the extreme volatility, Aave’s performance underscores the evolving maturity and resilience of DeFi markets.
«The protocol operated flawlessly, automatically liquidating a record $180M worth of collateral in just one hour, without any human intervention,» Kulechov said in a Friday X post. «Once again, Aave has proven its resilience.»
Key price action:
- AAVE sustained a dramatic flash crash on Friday, declining 64% from $278.27 to $100.18 before recuperating to $240.09.
- The DeFi protocol demonstrated remarkable resilience with its native token’s 140% recovery from the intraday lows, underpinned by substantial trading volume of 570,838 units.
- Following the volatility, AAVE entered consolidation territory within a narrow $237.71-$242.80 range as markets digested the dramatic price action.
Technical Indicators Summary
- Price range of $179.12 representing 64% volatility during the 24-hour period.
- Volume surged to 570,838 units, substantially exceeding the 175,000 average.
- Near-term resistance identified at $242.80 capping rebound during consolidation phase.

Blockchain Will Drive the Agent-to-Agent AI Marketplace Boom

AI agents, software systems that use AI to pursue goals and complete tasks on behalf of users, are proliferating. Think of them as digital assistants that can make decisions and take actions towards goals you set without needing step-by-step instructions — from GPT-powered calendar managers to trading bots, the number of use cases is expanding rapidly. As their role expands across the economy, we have to build the right infrastructure that will allow these agents to communicate, collaborate and trade with one another in an open marketplace.
Big tech players like Google and AWS are building early marketplaces and commerce protocols, but that raises the question: will they aim to extract massive rents through walled gardens once more? Agents’ capabilities are clearly rising, almost daily, with the arrival of new models and architectures. What’s at risk is whether these agents will be truly autonomous.
Autonomous agents are valuable because they unlock a novel user experience: a shift from software as passive or reactive tools to active and even proactive partners. Instead of waiting for instructions, they can anticipate needs, adapt to changing conditions, and coordinate with other systems in real time, without the user’s constant input or presence. This autonomy in decision-making makes them uniquely suited for a world where speed and complexity outpace human decision-making.
Naturally, some worry about what greater decision-making autonomy means for work and accountability — but I see it as an opportunity. When agents handle repetitive, time-intensive tasks and parallelize what previously had to be done in sequence, they expand our productive capacity as humans — freeing people to engage in work that demands creativity, judgment, composition and meaningful connection. This isn’t make-believe, humanity has been there before: the arrival of corporations allowed entrepreneurs to create entirely new products and levels of wealth previously unthought of. AI agents have the potential to bring that capability to everyone.
On the intelligence side, truly autonomous decision-making requires AI agent infrastructure that is open source and transparent. OpenAI’s recent OSS release is a good step. Chinese labs, such as DeepSeek (DeepSeek), Moonshot AI (Kimi K2) and Alibaba (Qwen 3), have moved even quicker.
However, autonomy is not purely tied to intelligence and decision making. Without resources, an AI agent has little means to enact change in the real world. Hence, for agents to be truly autonomous they need to have access to resources and self-custody their assets. Programmable, permissionless, and composable blockchains are the ideal substrate for agents to do so.
Picture two scenarios. One where AI agents operate within a Web 2 platform like AWS or Google. They exist within the limited parameters set by these platforms in what is essentially a closed and permissioned environment. Now imagine a decentralized marketplace that spans many blockchain ecosystems. Developers can compose different sets of environments and parameters, therefore, the scope available to AI agents to operate is unlimited, accessible globally, and can evolve over time. One scenario looks like a toy idea of a marketplace, and the other is an actual global economy.
In other words, to truly scale not just AI agent adoption, but agent-to-agent commerce, we need rails that only blockchains can offer.
The Limits of Centralized Marketplaces
AWS recently announced an agent-to-agent marketplace aimed at addressing the growing demand for ready-made agents. But their approach inherits the same inefficiencies and limitations that have long plagued siloed systems. Agents must wait for human verification, rely on closed APIs and operate in environments where transparency is optional, if it exists at all.
To act autonomously and at scale, agents can’t be boxed into closed ecosystems that restrict functionality, pose platform risks, impose opaque fees, or make it impossible to verify what actions were taken and why.
Decentralization Scales Agent Systems
An open ecosystem allows for agents to act on behalf of users, coordinate with other agents, and operate across services without permissioned barriers.
Blockchains already offer the key tools needed. Smart contracts allow agents to perform tasks automatically, with rules embedded in code, while stablecoins and tokens enable instant, global value transfers without payment friction. Smart accounts, which are programmable blockchain wallets like Safe, allow users to restrict agents in their activity and scope (via guards). For instance, an agent may only be allowed to use whitelisted protocols. These tools allow AI agents not only to behave expansively but also to be contained within risk parameters defined by the end user. For example, this could be setting spending limits, requiring multi-signatures for approvals, or restricting agents to whitelisted protocols.
Blockchain also provides the transparency needed so users can audit agent decisions, even when they aren’t directly involved. At the same time, this doesn’t mean that all agent-to-agent interactions need to happen onchain. E.g. AI agents can use offchain APIs with access constraints defined and payments executed onchain.
In short, decentralized infrastructure gives agents the tools to operate more freely and efficiently than closed systems allow.
It’s Already Happening Onchain
While centralized players are still refining their agent strategies, blockchain is already enabling early forms of agent-to-agent interaction. Onchain agents are already exhibiting more advanced behavior like purchasing predictions and data from other agents. And as more open frameworks emerge, developers are building agents that can access services, make payments, and even subscribe to other agents — all without human involvement.
Protocols are already implementing the next step: monetization. With open marketplaces, people and businesses are able to rent agents, earn from specialized ones, and build new services that plug directly into this agent economy. Customisation of payment models such as subscription, one-off payments, or bundled packages will also be key in facilitating different user needs. This will unlock an entirely new model of economic participation.
Why This Distinction Matters
Without open systems, fragmentation breaks the promise of seamless AI support. An agent can easily bring tasks to completion if it stays within an individual ecosystem, like coordinating between different Google apps. However, where third-party platforms are necessary (across social, travel, finance, etc), an open onchain marketplace will allow agents to programmatically acquire the various services and goods they need to complete a user’s request.
Decentralized systems avoid these limitations. Users can own, modify, and deploy agents tailored to their needs without relying on vendor-controlled environments.
We’ve already seen this work in DeFi, with DeFi legos. Bots automate lending strategies, manage positions, and rebalance portfolios, sometimes better than any human could. Now, that same approach is being applied as “agent legos” across sectors including logistics, gaming, customer support, and more.
The Path Forward
The agent economy is growing fast. What we build now will shape how it functions and for whom it works. If we rely solely on centralized systems, we risk creating another generation of AI tools that feel useful but ultimately serve the platform, not the person.
Blockchain changes that. It enables systems where agents act on your behalf, earn on your ideas, and plug into a broader, open marketplace.
If we want agents that collaborate, transact, and evolve without constraint, then the future of agent-to-agent marketplaces must live onchain.

‘Largest Ever’ Crypto Liquidation Event Wipes Out 6,300 Wallets on Hyperliquid

More than 1,000 wallets on Hyperliquid were completely liquidated during the recent violent crypto sell-off, which erased over $1.23 billion in trader capital on the platform, according to data from its leaderboard.
In total, 6,300 wallets are now in the red, with 205 losing over $1 million each according to the data, which was first spotted by Lookonchain. More than 1,000 accounts saw losses of at least $100,000.
The wipeout came as crypto markets reeled from a global risk-off event triggered by U.S. President Donald Trump’s announcement of a 100% additional tariff on Chinese imports.
The move spooked investors across asset classes and sent cryptocurrency prices tumbling. Bitcoin briefly dropped below $110,000 and ether fell under $3,700, while the broader market as measured by the CoinDesk 20 (CD20) index dropped by 15% at one point.
The broad sell-off led to over $19 billion in liquidations over a 24 hours period, making it the largest single-day liquidation event in crypto history by dollar value. According to CoinGlass, the “actual total” of liquidations is “likely much higher” as leading crypto exchange Binance doesn’t report as quickly as other platforms.
Leaderboard data reviewed by CoinDesk shows the top 100 traders on Hyperliquid gained $1.69 billion collectively.
In comparison, the top 100 losers dropped $743.5 million, leaving a net profit of $951 million concentrated among a handful of highly leveraged short sellers.
The biggest winner was wallet 0x5273…065f, which made over $700 million from short positions, while the largest loser, “TheWhiteWhale,” dropped $62.5 million.
Among the victims of the flush is crypto personality Jeffrey Huang, known online as Machi Big Brother, who once launched a defamation suit against ZachXBT, losing almost the entire value of his wallet, amounting to $14 million.
«Was fun while it lasted,» he posted on X.
Adding to the uncertainty, the ongoing U.S. government shutdown has delayed the release of key economic data. Without official indicators, markets are flying blind at a time when geopolitical risk is rising.
