SOFI TAPS BITCOIN LIGHTNING FOR REMITTANCES: SoFi Technologies will soon allow remittance payments on top of the Bitcoin layer-2 Lightning Network through a partnership with Lightspark, aiming to bring real-time international money transfers to its members. SoFi’s remittance product, which is expected to roll out later this year, will allow users to send U.S. dollars through the SoFi app, with recipients receiving local currency deposits abroad, using Lightspark’s Universal Money Address (UMA). Lightspark’s UMA provides access to a global payment rail designed for speed and scale. Transfers will display upfront exchange rates and fees, addressing longstanding pain points in traditional remittance services. The launch follows SoFi’s reentry into crypto, after halting services in 2023 during its transition to a national bank. Earlier this year, it revealed plans to offer international remittances through blockchain and stablecoins and allow users to invest in crypto. — Jamie Crawley Read more.
BITLAYER ENTERS SOLANA WITH YBTC: Bitcoin DeFi project Bitlayer has partnered with Kamino Finance and Orca to bring its bitcoin-backed token, YBTC, to the Solana ecosystem. This integration is intended to combine Bitlayer’s security with Solana’s speed and scalability, aligning with Bitlayer’s goal of expanding the Bitcoin DeFi sector. It will provide bitcoin holders with native BTC exposure and yield opportunities, said Charlie Hu, co-founder of Bitlayer. YBTC, pegged 1:1 with BTC, is central to Bitlayer’s BitVM bridge, which is designed for trust-minimized bitcoin transfers by eliminating centralized intermediaries. The token serves as a direct representation of users’ locked BTC within the Bitlayer ecosystem, enabling seamless interoperability between Bitcoin and decentralized finance applications. By holding YBTC, Solana users can maximize yields through Kamino’s institutional-grade earn vaults, which provide auto-compounding and optimized BTC-denominated returns, helping assets grow effortlessly. — Omkar Godbole Read more.
VALANTIS ACQUIRES stHYPE: Valantis, a decentralized exchange (DEX) protocol, has acquired Staked Hype (stHYPE), the second-largest liquid staking token (LST) on Hyperliquid. Financial terms of the deal were not disclosed. stHYPE, which launched as the first LST on HyperEVM, currently holds about $180 million in total value locked (TVL), according to the stHYPE website. Following the deal, stHYPE’s operations, development, and scaling will be managed by Valantis Labs. Addison Spiegel, founder of Thunderhead, the team behind stHYPE, will serve as an advisor to Valantis. Liquid staking has become a central pillar within Hyperliquid’s ecosystem. According to DeFiLlama, liquid staking accounts for more than half of Hyperliquid L1’s $2.26 billion in DeFi TVL. The acquisition builds on Valantis’ earlier launch of LST-specific DEX pools for both stHYPE and hHYPE, which together have attracted nearly $70 million in TVL and processed more than $500 million in trading volume. — Oliver Knight Read more.
HYPERBEAT GETS $5.2M IN SEED: Hyperbeat, a protocol powering yield infrastructure on the Hyperliquid decentralized exchange, has closed a $5.2 million oversubscribed seed round co-led by ether.fi Ventures and Electric Capital. The raise will be used to build out their yield infrastructure for traders, protocols, and institutions that are tapped into the Hyperliquid ecosystem. The round also drew investments from Coinbase Ventures, Chapter One, Selini, Maelstrom, Anchorage Digital, and community backers via the HyperCollective. Hyperbeat serves as the native yield layer for Hyperliquid, building permissionless financial infrastructure that allows anyone to earn, stake, and spend directly from their on-chain portfolio. It unlocks yield generated by Hyperliquid’s funding rates—previously accessible only to sophisticated market participants—and packages it into simple, tokenized vaults. The news of the seed raise comes as Hyperliquid’s total value locked surpasses $2.1 billion, and as institutions are starting to develop greater interest in its ecosystem. — Margaux Nijkerk Read more.

- SkyBridge Capital, Anthony Scaramucci’s investment management firm, plans to tokenize $300 million worth of its hedge funds on the Avalanche network. The firm is bringing its Digital Macro Master Fund and Legion Strategies on-chain in partnership with tokenization provider Tokeny and its parent, Apex Group, which manages more than $3.5 trillion in assets, according to the press release shared with CoinDesk. Apex acquired Tokeny earlier this year. The initiative uses the ERC-3643 token standard with operational support from Apex’s Digital 3.0 platform, which handles issuance, administration, and distribution. — Kristzian Sandor Read more.
- Thumzup Media, which counts Donald Trump Jr. as a large shareholder, said it will acquire Dogehash Technologies, Inc. in an all-stock deal, pivoting from digital marketing into industrial-scale crypto mining. Under the agreement, Dogehash shareholders will receive 30.7 million Thumzup shares, according to a Tuesday release, valuing the transaction at $153.8 million, based on the shares’ closing price. The combined company will rebrand as Dogehash Technologies Holdings, Inc. and list on Nasdaq under the ticker XDOG, pending shareholder approval later this year. The company says it will also use Dogecoin’s DogeOS layer 2 to stake in DeFi products, aiming to boost miner returns beyond standard rewards. — Sam Reynolds Read more.
Regulatory and Policy
- The crypto industry is mounting a counteroffensive against Wall Street bankers’ bid to rewrite the U.S.’ new stablecoin law, arguing that attempts to roll back core provisions of the GENIUS Act would tilt the field toward traditional banks. In a letter to Senate Banking Committee leaders dated Aug. 19, the Crypto Council for Innovation and the Blockchain Association urged lawmakers to reject proposals from the American Bankers Association, Bank Policy Institute and state banking groups that called for stripping out Section 16(d) of the law and banning yield programs offered by affiliates of stablecoin issuers. Section 16(d) allows subsidiaries of state-chartered institutions to conduct money transmission across state lines in support of stablecoin issuer activities, ensuring holders can redeem their tokens nationwide without needing separate state licenses. Banking groups warned earlier this month that allowing state-chartered, uninsured institutions to issue stablecoins and operate nationwide would amount to regulatory arbitrage, bypassing state licensing regimes. — Sam Reynolds Read More
- The U.S. Federal Reserve’s newest vice chair who supervises Wall Street banking, Michelle Bowman, made a crypto speech on Tuesday that could have been uttered by one of the industry’s own policy wonks, advocating that banks get behind the digital assets surge and that the Fed give the sector rules that won’t get in crypto’s way. At the Wyoming Blockchain Symposium, Bowman warned banks that don’t embrace the shift toward crypto «will play a diminished role in the financial system more broadly,» and she further underlined what’s already been an obvious change in crypto sentiment from U.S. banking regulators. «Your industry has already experienced significant frictions with bank regulators applying unclear standards, conflicting guidance, and inconsistent regulatory interpretations,» she said. «We need a clear, strategic regulatory framework that will facilitate the adoption of new technology, recognizing that in some cases, it may be inadequate and inappropriate to apply existing regulatory guidance to address emerging tech.» — 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.
