EMURGO announced that SecondFi, the Cardano wallet that was hacked, will permanently cease operations.
ChainCatcher reports that Cardano's founding entity, EMURGO, stated on Monday that SecondFi, the wallet service that suffered a hack, will not resume normal operations even after a security audit is completed. All users are required to migrate their assets through the official recovery process. SecondFi is a rebranded version of the Yoroi wallet and is described by EMURGO as Cardano's largest wallet provider. According to EMURGO's incident report on June 25th, the service suffered four separate wallet thefts on June 22nd, with 374 addresses compromised and approximately 16 million ADA (worth about $2.4 million at the time) stolen. The team also took emergency measures to recover approximately 129 million ADA. EMURGO stated that compromised wallets should be considered permanently exposed at the address and private key levels, and restoring the damaged seed phrase to other wallets cannot eliminate the risk. EMURGO plans to launch an isolated wallet state inspection tool this week, followed by a secure export tool and an offline migration workshop in Tokyo. They are also building a dedicated recovery fund for the on-chain recovery system, and will return assets to affected users after the external audit is completed.
Tencent shares surged over 5% intraday, marking a narrative reversal: WorkBuddy users increased by two orders of magnitude, and WeChat's AI "Xiaowei" opens up greater possibilities.
According to BlockBeats, on July 6th, Bitget data showed that Tencent Holdings' Hong Kong-listed shares rose over 5% intraday, reaching HK$453. Tencent, once criticized for its "slow AI development," is experiencing a narrative reversal. In May, at the shareholders' meeting, Ma Huateng frankly admitted, "A year ago we thought we were on a ship, but then we found it was leaking, and now we're standing on it but can't sit down." However, in just a few months, WorkBuddy's monthly active users (MAU) exceeded 20 million, daily active users (DAU) exceeded 13 million, and the DAU/MAU ratio reached 65%-75%, with stickiness comparable to Slack-level office tools. With 43 versions released in three months and updates continuing even during the May Day holiday, Tencent internally positions it as its third phenomenal product after QQ and WeChat. WorkBuddy's success hinges on two key barriers: first, its extremely simple installation—a desktop client plus a WeChat mini-program, with commands sent from the phone after WeChat authorization and executed automatically on the PC, completely bypassing the high command-line deployment hurdles of similar foreign products; second, the activation of Tencent's entire ecosystem in the Agent era—integrating with Tencent Docs, Tencent Meeting, WeChat Work, and over 30 external tools, expanding the SkillHub skill library from 79,000 to 790,000, allowing for automatic data retrieval, file generation, and distribution with a simple command like "create a PPT of last week's sales data and send it to colleagues at a meeting." This leap from a chat bot to a tool that gets things done transforms a fragmented toolchain into a competitive advantage. Furthermore, this groundbreaking product, the first in Tencent's history to conduct on-the-ground promotion, reflects a genuine commitment to penetrating the B2B market. Even greater potential lies in WeChat AI. WeChat's AI assistant, "Xiaowei," launched a small-scale gray-scale test on June 20th, supporting voice or text messaging, Moments posting, and accessing mini-programs for appointment booking and food delivery. It even generates mini-program prototypes using natural language. This marks the first time this super app with 1.43 billion monthly active users has entered the intelligent agent arena. JPMorgan Chase estimates, based on probability weighting, that WeChat's AI Agent could generate approximately 126 billion yuan in incremental revenue and 88 billion yuan in incremental operating profit by 2030. However, Goldman Sachs warns of three major concerns: the potential resource duplication from the parallel operation of its self-developed WeLM model and the mixed-source model; the possibility that inference costs after full rollout could erode 5%-17% of the projected adjusted operating profit for Q4; and the unclear short-term monetization path. The core difference between the two institutions lies in the timing: JPMorgan Chase believes the public beta has transformed WeChat AI from an "abstract option" into a "traceable milestone," while Goldman Sachs believes the short-term cost-benefit asymmetry requires further quarterly verification. In terms of the underlying model, Hunyuan 3 Preview has been integrated into 131 Tencent products, with token usage increasing tenfold compared to the second generation. It ranks first in usage on the OpenRouter platform. However, the prediction that Ma Huateng (Pony Ma) might not be able to maintain his position even after taking the lead still holds true. The ecosystem is the natural foundation for Tencent to act as an agent, but WeChat AI faces complex challenges in handling transactions, advertising, payments, merchants, fairness, and regulation.
The South African Revenue Office has released tax guidelines for crypto assets, potentially subjecting approximately 6 million users to audits.
Odaily Odaily that the South African Revenue and Taxation Office (SARS) released a draft guidance on cryptocurrency taxation on July 1, 2026, proposing compliance rules for approximately 5.8 million to 6 million cryptocurrency users in South Africa, with a public comment period open until August 31, 2026. Under the updated framework, crypto assets are classified as intangible assets, not foreign or traditional currencies, and taxpayers are not required to pay tax on unrealized gains or losses while simply holding the assets. Tax obligations are triggered upon disposal of the assets. If an individual's crypto activity is deemed similar to business activities or short-term day trading, profits will be classified as gross income and taxed at marginal rates ranging from 18% to 45%. If crypto assets are held as long-term investments, capital gains tax will be levied on disposal gains, with an effective individual tax rate ranging from 18% to 36%. The draft also treats the exchange of crypto assets as a barter transaction, with tax consequences arising immediately at the local market value at the time of exchange. SARS announced the deployment of a Crypto Revenue Augmentation Unit to track and audit digital wallets, and urged taxpayers who had previously failed to disclose crypto earnings to complete their filings through a voluntary disclosure program to avoid administrative penalties from increased enforcement after the August deadline.
