On Monday, the oracle network Chainlink released the cross-chain interoperability protocol CCIP 2, making significant upgrades to its communication and cross-chain bridge infrastructure. The new version allows enterprises to add their own security verification checks on top of Chainlink's default network of 16 independent node operators. Enterprises can run their own validators or hire external service providers such as Infosys and Nethermind. Chainlink stated that users should not be forced to become "cross-chain security infrastructure experts."This upgrade comes about five months after the Kelp DAO was hacked in April of this year. The attackers are reportedly linked to the North Korean Lazarus group, stealing approximately $292 million in rsETH by deceiving the single validator relied upon by the Kelp cross-chain bridge, which operates on LayerZero. LayerZero blamed Kelp for using only a single validator, while Kelp stated that LayerZero employees had reviewed its setup and raised no objections. Kelp subsequently announced that it would migrate rsETH to Chainlink.The upgrade also adjusts the security mechanism that Chainlink had previously heavily promoted; its risk management network will no longer operate as an independent review node, with such independent checks now provided by optional validators. This means that users who have not added any validators currently rely on a single validation network, whereas previously they relied on two. Existing Chainlink users have been automatically migrated to the new version, but the company has not disclosed which institutions are using the new validators, only stating that Aave and Maple have begun adopting other features of the upgrade.

Goldman Sachs Global Investment Research Department's South Korea stock analyst Chris Cha stated in a report on September 23 that KOSPI has the conditions for a short-term tactical breakout, but the continuous flow of liquidity from South Korean retail investors into the cryptocurrency market will make the index's subsequent upward movement more reliant on foreign capital and local institutions reconfiguring. The report noted that concerns about the Federal Reserve's interest rates have been partially digested by the market, and risk appetite has shifted towards proxy AI themes.The report pointed out that South Korean memory chips provide fundamental support, with fourth-quarter DRAM contract prices expected to grow double digits quarter-on-quarter, and the ramp-up of HBM4 capacity will continue to limit the supply of standard server DRAM. Samsung Electronics' large shareholder returns, continuous buying by institutions, and foreign capital turning into net buying may drive KOSPI towards the resistance zone of 7000 to 7200 points.The report also indicated that the capacity of local South Korean retail investors to absorb has weakened. After Bitcoin returned to $85,000, cryptocurrency trading in South Korea has heated up. According to DefiLlama data cited in the report, Upbit's single-day spot trading volume on June 13 was approximately $770 million, which rose to $1.817 billion on September 22, an increase of about 136%. Based on the total trading volume of $3.27 billion on that day across South Korea's five major trading platforms, Upbit alone accounted for over half. Goldman Sachs believes this will make KOSPI more reliant on foreign and institutional buying in the future, and October is a critical window to test whether foreign capital will continue to increase its investment in South Korean semiconductor and AI assets.

Two ChatGPT users from California filed a proposed class action lawsuit against OpenAI in the United States District Court for the Northern District of California this month, accusing the company of failing to adequately inform users that their real conversations were being handed over to external contractors for processing. The lawsuit was served to OpenAI on September 2, focusing on its internal initiative Project Lily. According to the complaint, "AI data reviewers" and "chatbot evaluators" recruited through a third-party staffing company read real ChatGPT prompts and complete conversations, summarize user intent, and score and comment on responses from four models on a scale of 1 to 7.This process is known in the industry as reinforcement learning from human feedback (RLHF), which is a fundamental method for enhancing chatbot capabilities. The complaint states that users were never explicitly informed that a person, rather than a machine, might be reading their conversations. OpenAI filters conversations through an automated system before human review, but the complaint alleges that the filters cannot intercept all content, and personal details sometimes still reach contractors. 404 Media first reported on the project on September 14 and found that the reviewers' dashboard included "user memory summaries," which could expose users' approximate locations, occupations, or private life information, even though usernames had been removed.OpenAI stated that such reviews aim to reduce two behaviors: chatbots behaving too much like humans and overly catering to users, referred to by researchers as "flattery." The complaint raises eight legal claims, including violations of California's Unfair Competition Law, Consumer Privacy Act, and common law claims for intrusion into private affairs, with the plaintiffs seeking damages, restitution of unjust enrichment, and punitive damages.

Axios reported that allies of Trump are attacking Dario Amodei, the CEO of the artificial intelligence company Anthropic, as a representative of the "doomsday" narrative surrounding artificial intelligence and one of the founders of the effective altruism movement. Sources say that during the midterm elections, allies may target Anthropic when countering his warnings about AI safety; due to his political stance and concerns about AI safety, he is seen as an easy target. This is concerning for investors as the company is preparing for an anticipated record-breaking initial public offering.The report states that a memo began circulating internally within the White House this week, attempting to portray effective altruism as a fringe, cult-like group detached from mainstream America, with Axios claiming to have obtained the document. The memo was written by a Trump political advisor not currently employed by the White House, stating that effective altruism "has established a doomsday pipeline for artificial intelligence," placing Amodei at the foundational position of the movement, while also mentioning his sister, Daniela Amodei, president of Anthropic, referring to these connections as "Anthropic nodes." A source close to the government said that Amodei embodies an ideology and globalist innovation path that contradicts the president's "America First" agenda.Anthropic has been distancing itself from effective altruism. Daniela Amodei stated in a 2025 Wired report that she does not agree with the term. Dario Amodei has insisted in interviews that he is not a member of the movement and has promoted the benefits of artificial intelligence.

The PermissionDelegationV1_1 upgrade of the XRP Ledger entered a 14-day activation countdown on September 21, having received support from 29 of the 35 trusted validator nodes. If the support rate remains above 80% during this period, the upgrade could officially activate as early as October 5 at 11:18 UTC; at least 28 validator nodes must continue to support it, or the countdown will reset.This feature allows accounts to split permissions by role. For example, a stablecoin issuer can allow a connected compliance system to approve customer accounts holding its tokens while keeping the keys with full control offline; operational accounts can gain payment permissions but cannot change keys or delegate authority to others. Each trustee can have up to 10 permissions, and the main account can modify or revoke them at any time.This is the network's second attempt to introduce this feature. The original version had vulnerabilities that attackers could exploit to make others pay transaction fees with improperly signed transactions, and by repeatedly submitting high-fee transactions, they could deplete the victim's XRP balance. This vulnerability was reported by community testers on September 15, 2025, and validator nodes were advised to reject the amendment, so it was never activated. The fixed version was released with xrpld 3.3.0, changing the way unauthorized transactions are rejected, ensuring that fees are not deducted before signature verification.

The TCG card drawing and trading platform Pull.Fun, aimed at Pokémon card collectors worldwide, announced that its mascot token $TAKO has launched on the Robinhood Chain.According to GMGN data, its token market value briefly surpassed 4 million USD, with a current market value of 2.3 million USD.

Circle announced that the Digital Asset Backed Borrowing and Lending (DABB) feature has been launched on the Arc and Ethereum networks, available to eligible Circle Mint institutional clients.Clients can deposit Bitcoin, mint Circle Wrapped Bitcoin (cirBTC), and supply cirBTC as collateral to third-party lending markets in a single process using a self-custody wallet. The USDC borrowed will be directly settled into the Circle Mint account balance, without the need to sell the pledged Bitcoin; collateral can be released after repaying the USDC.

Donald Trump and his family business are continuing to expand their investments in artificial intelligence, data centers, power infrastructure, and related technology companies. Financial disclosures show that after Trump's return to the White House, his investment accounts have reported nearly 30,000 securities transactions, including buying and selling stocks of chip, server, and energy infrastructure companies such as Dell Technologies, Micron Technology, GE Vernova, Broadcom, Texas Instruments, Credo Technology, and Advanced Micro Devices. It is currently unclear whether Trump still holds these shares, as related transactions do not require real-time disclosure, and Trump has not placed his assets in a blind trust.Trump Media Technology Group plans to merge with the fusion company TAE Technologies, which intends to build power generation facilities amid the growing demand for electricity in AI data centers. Truth Social also plans to authorize platform data to AI labs through TruthAPI and has launched a search tool supported by technology from Perplexity. Donald Trump Jr. serves as a partner at 1789 Capital, which has completed fundraising for a $1.2 billion fund, focusing on investments in digital infrastructure such as data centers, and has invested in Cerebras, Perplexity, and xAI. Eric Trump, on the other hand, invests in defense, robotics, and AI data processing companies through American Ventures.The White House denies any conflict of interest, stating that Trump's investments are entirely managed by independent managers, with related assets held in discretionary accounts and automatically replicating indices such as Schwab 1000 through computer models, meaning Trump and his family cannot decide on specific investments and transaction timings.

According to The Defiant, Blockworks announced the launch of the Agentic Detection feature, allowing cryptocurrency exchanges and banks to receive compliance alerts directly from AI agents without waiting for human analysts to review. This feature went live on Thursday in Messari Monitoring, with each alert marked as generated by the agent or verified by an analyst.Blockworks stated that previously, analysts took about 5 minutes to verify each dynamic, while their proprietary model, trained on years of work by Messari analysts, can identify alerts in seconds. Agentic Detection is turned off by default, and clients can enable it view by view. Co-founder Jason Yanowitz mentioned that as on-chain activity scales, the market prices events in seconds rather than minutes, and clients need near real-time alerts.This detection layer is built on seven years of analyst coverage data, and the agent can read X, GitHub, governance forums, Discord, Telegram, project blogs, and over 1,000 news sources, covering more than 1,000 assets. Blockworks acquired Messari for over $10 million on June 12, after Messari completed a Series A extension financing led by ParaFi and Reciprocal Ventures in April, with a valuation of $192 million, with participation from Coinbase Ventures, MoonPay Ventures, and others.

The U.S. Securities and Exchange Commission (SEC) stated that tokenization is expected to reduce costs in market infrastructure aspects such as issuance, trading, transfer, settlement, and ownership records, while enhancing transparency and liquidity. The SEC approved a temporary, conditional "Innovation Exemption," allowing tokenized NMS stocks to be traded in a limited manner on certain on-chain venues—tokenized securities trading venues (TSVs).It is reported that TSVs meeting the exemption conditions can conduct approved trading through automated market makers and liquidity pools, but must meet requirements for public disclosure, trading transparency, circuit breaker coordination, record keeping, and technical safeguards, while also being subject to limits on the number of stock codes and trading volume.The SEC indicated that this move aims to observe the operation of on-chain trading venues and market participants, providing data for the formulation of long-term regulatory rules in the future.

X has launched the U.S. Cashtag Partner Program, with partners including Coinbase, Kraken, Gemini, Interactive Brokers, and Moomoo.Users can click on supported stocks, ETFs, or cryptocurrency Cashtags to view price charts and related posts, then select "Trade" to jump to the app or website of the participating broker. Trades are executed by the broker, not on X.

According to The Defiant, Kraken has launched three xStocks vaults, allowing eligible customers to deposit SPYx, QQQx, and NVDAx into the vaults while earning floating returns while retaining exposure to tokenized stocks or ETFs. The vault initially shows an estimated net APY of 2% for SPYx and QQQx, and 1.8% for NVDAx. Kraken charges a 25% performance fee on vault earnings, and the displayed interest rate has already deducted this fee; rewards will be converted into the same type of xStock and automatically reinvested into the customer's balance.The strategy is designed by Sentora and is responsible for risk management, while Veda provides the vault infrastructure. After customers deposit xStock, Kraken transfers it to an embedded self-custody wallet on Ink, packages it, and deposits it into the Veda vault; Sentora then cross-chain transfers the packaged xStock to Solana and deposits it as collateral in the Kamino lending market. After borrowing stablecoins, it is deployed into selected DeFi strategies, and the returns are ultimately converted back into the deposited xStock. Customers do not need an external wallet or mnemonic phrase but can export the private key; redemption requires a three-day wait for funds to arrive.Kraken's documentation shows that the strategy uses leverage to generate returns by borrowing stablecoins and lists risks such as smart contracts, liquidity, bad debts, liquidation, cross-chain execution, and downstream assets, with losses shared proportionally among vault users. xStock holders do not have voting rights, dividend rights, or legal claims to the underlying stocks. The vault is currently available to the European Economic Area and other supported markets, while users from the United States, United Kingdom, Canada, Australia, the United Arab Emirates, and sanctioned countries cannot use it.
