first_img Arbitrum Security Committee urgently suspended the activation of the new contract Stylus and added BoLD protection

On October 2, at 11:30 AM Eastern Time, the Arbitrum Security Committee executed an emergency upgrade on Arbitrum One and Nova, suspending the activation of all new Stylus contracts on both chains, while adding a protective mechanism against BoLD single-step proofs in the dispute system of Arbitrum One. The Arbitrum Foundation stated that this action is part of ongoing proactive security measures aimed at protecting the security and integrity of the network.Stylus allows developers to write smart contracts using languages such as Rust and C++, while maintaining compatibility with the Ethereum Virtual Machine, with its programs compiled into WebAssembly format. This suspension primarily targets manually written WASM programs that do not use the standard Stylus compiler toolchain and have not yet been patched by the current version of ArbOS. The Security Committee increased the gas required for activation to the theoretical maximum by calling ArbOwner.setWasmActivationGas(2^64 - 1), making new activations economically unfeasible. Activated Stylus contracts are unaffected and can continue to execute and renew, and the deployment and execution of Solidity contracts are also unrestricted.The newly added BoLD protection allows anyone to pause the settlement from Arbitrum One to Ethereum when two conflicting and accepted answers appear in the same dispute step, which may delay unconfirmed withdrawals to allow the Security Committee to deploy fixes. Officials pointed out that the currently discovered Stylus-related vulnerabilities mainly affect the activity of the chain, such as denial-of-service attacks, and do not jeopardize user funds.

first_img Crypto.com subsidiary AI agency ai.com has been secretly developing, and it has not launched nearly 8 months after its Super Bowl debut

The personal AI agent business ai.com under Crypto.com has not yet been opened to the public since its debut during the Super Bowl in February this year. According to Cointelegraph, ai.com spent $15 million on advertising during the fourth quarter of the Super Bowl to promote the launch of its AI platform, leading to a surge of users rushing to reserve personal AI agent accounts, which caused the website to crash within minutes. Nearly 8 months later, the site still displays a message indicating that due to high demand, AI agent generation is in queue. A spokesperson for Crypto.com confirmed that the platform is still under development, stating that ai.com continues to advance in stealth mode and will provide more details when it is officially released to the public.The AI agents of ai.com are positioned beyond financial scenarios. In a statement released in February, it was announced that personal agents could arrange work, send messages, operate across applications, and build projects, and it also claimed that agents could independently develop missing capabilities and share improvements within the network. Meanwhile, competitors have launched AI assistants for more specific tasks: Robinhood announced on Tuesday that it could execute automated trading within the app using AI agents, Kraken launched AI financial tools in July, and Bitget introduced the AI trading assistant GetAgent in June. Anthropic introduced computer use in Claude Cowork in March, and OpenAI launched ChatGPT Work in July.During this period, Crypto.com continues to invest in AI business.

first_img Tencent secretly developed the Personal Agent product Handy Bot

According to "Dujia," Tencent is secretly developing a Personal Agent product called "Handy Bot" and plans to launch an independent app. Currently, the product has quietly launched a service account on WeChat, with the description "Your Personal AI Agent." Since the product is still in the internal testing phase, specific information is subject to official announcements.The report states that the industry is currently hotly discussing the narrative of Personal Agents, with Meta's recently launched Muse pushing the popularity of consumer-grade intelligent agents to new heights. Unlike traditional chatbots that are conversation-driven, Personal Agents are centered around human core state boundaries, where AI has a long-term operational environment and can receive macro goals to continuously advance tasks in the background. Meta Muse assigns each user an independent Secure VM (Virtual Machine) for security, isolating browser and web operations for tasks such as price comparison shopping, email processing, and itinerary monitoring.Domestic manufacturers are also entering the pre-research phase. The Alibaba Qianwen team proposed creating a Personal Agent for users at the Yunqi Conference, and ByteDance's Doubao has also been reported to be developing a personal assistant product, previously codenamed "Spell." The industry believes that implementation needs to balance model task planning capabilities, ecosystem tool openness, and compliance with privacy boundaries.

first_img Robinhood launches AI trading agent, perpetual contracts, and weekend stock trading

According to CoinDesk, brokerage Robinhood (HOOD) announced at the HOOD Summit held in Houston, Texas, that it will launch executable trading AI agents, cryptocurrency perpetual contracts with up to 10x leverage, and weekend trading for U.S. stocks, while extending options trading hours, providing more intraday margin, and introducing contracts based on corporate earnings metrics.Robinhood Agents allow customers to create AI agents within the app, choose models from OpenAI or Anthropic, and authorize them to access independent trading accounts. The agents can analyze the market, create watchlists, and trade stocks, options, and crypto assets. A feature called Loops allows customers to give long-term instructions to the agents to monitor the market and execute strategies when specific conditions arise. Since opening its trading infrastructure to external AI agents earlier this year, over 150,000 agent accounts have been created. By default, every trade proposed by the agent requires customer approval, and users can disable this protection; agents cannot use margin when they go live and can only utilize funds in dedicated accounts.Regarding perpetual contracts, Robinhood plans to offer them to eligible U.S. customers through Robinhood Derivatives and Bitstamp, initially focusing on crypto assets, with Bitcoin and Ethereum contracts having leverage up to 10x, while other supported assets starting at 3x. Additionally, Robinhood will provide earnings binary contracts through Cboe, allowing customers to trade directly on whether companies meet revenue, earnings per share, and other metrics; weekend trading will offer select stocks and ETFs through Bruce ATS.
