U.S. Treasury Secretary Janet Yellen stated that last month's expansion of the U.S. Treasury bond buyback program was aimed at calming the frenzied sentiment in the bond market and pushing market prices back to equilibrium. She denied that the Treasury's buyback of government bonds was equivalent to the Federal Reserve's quantitative easing, stating that the measure was similar to the Federal Reserve's past distortion operations.

According to official news, the Circle Cross-Chain Transfer Protocol (CCTP) now supports a fast transfer prepayment fee feature. Previously, the protocol fee would be directly deducted from the USDC transfer amount on the target chain; with this update, developers can pre-quote and collect fees using the native Gas token or USDC from the source chain before executing the transfer, thereby simplifying the fee handling for cross-chain transfers and ensuring that users receive the expected amount of USDC.It is reported that the prepayment fee mechanism mainly improves the predictability of fees in cross-chain applications. Users do not have to bear the reduction in the actual amount received due to additional deductions on the target chain; at the same time, the CCTP Quote API can uniformly calculate fees for different supported chains and integrate Fast Transfer and Forwarding fees into a single quote, so developers do not need to build systems to separately calculate multiple protocol fees. In addition, fees can be paid directly using the native token of the source chain, which will not reduce or affect the actual transferred USDC balance.Currently, the prepayment fee feature supports USDC transfers on all EVM chains covered by CCTP, but it does not support transfers initiated from Solana; transfers to Solana are still supported. Developers can obtain specific fee quotes through the Quote API and integrate this feature, and relevant developers can refer to the CCTP official documentation to build a more predictable cross-chain USDC transfer process.

Blockchain analysis company Chainalysis estimates that France's potential taxable cryptocurrency activity will reach $9.4 billion by 2025, including $5.2 billion from payments, $2.5 billion from capital gains, and $1.7 billion from mining and staking income. French taxpayers reported only €368 million in net income for the 2024 fiscal year, involving about 24,000 people, an increase from approximately 7,700 people and €150.8 million in the previous year.Chainalysis stated that the non-compliance rate for cryptocurrency taxes in some countries may exceed 90%. The EU's eighth directive on administrative cooperation, DAC8, came into effect on January 1, 2026, requiring cryptocurrency service providers to collect user identity and transaction data. Tax authorities in member states will start exchanging relevant records cross-border from September 30, 2027; CARF currently covers about 14% of the world's potential taxable on-chain activities.

The U.S. Treasury Department will announce the maximum amount of 10 to 20-year U.S. Treasury bonds planned for repurchase on Wednesday at 11 AM Eastern Time (23:00 Beijing Time). On September 10, the U.S. Treasury will also disclose the exact amount purchased under the repurchase plan that will start in May 2024.Previously, the U.S. Treasury stated that before November 4, it would repurchase at least $4 billion in long-term U.S. Treasury bonds each time from the market, up from the previous operation of $2 billion. The Treasury still has the discretion to expand the repurchase scale.

Sources say that Anthropic has decided to terminate its plan to acquire the artificial intelligence startup Decart AI. Anthropic had previously conducted due diligence on Decart for a deal worth approximately $6 billion but ultimately chose to walk away, although both parties may explore other forms of collaboration in the future.The software and hardware collaborative optimization technology developed by Decart can enhance chip utilization efficiency and reduce AI training and inference costs. Anthropic has rarely engaged in large-scale mergers and acquisitions and is currently making significant investments in computing power to develop new products and serve customers, while preparing for an initial public offering that may approach or even exceed that of SpaceX.

Blockchain security company Hacken released an assessment report indicating that approximately half of the circulating USDT (about $91.3 billion on the Tron network) is controlled by a 2-of-3 multi-signature contract, which lacks built-in delays, cancellation processes, or reliable revocation mechanisms. Attackers only need to compromise two signature keys to change contract ownership, mint tokens, freeze addresses, clear frozen balances, or set transfer fees without accessing any user wallets. Hacken also discovered that Tether reuses the same set of six signature keys across three chains: Ethereum, Avalanche, and Celo, posing a risk of cross-chain spread.Meanwhile, stablecoin rating agency Bluechip upgraded Tether's company rating from D to C, citing that KPMG's audit showed Tether's reserves exceeded liabilities by $6.8 billion as of December 31, 2025. This is the first time Bluechip has adopted the expanded SMIDGE methodology, which incorporates Hacken's technical risk analysis. However, Hacken only gave USDT a cybersecurity score of 3.3 out of 10 and pointed out that the USDT smart contract does not have automatic reserve proof checks or a token minting cap. Once signers authorize a transaction, the contract can mint an unlimited number of tokens without a bank reserve proof.Hacken stated that it has not yet completed an equivalent assessment of Circle's USDC, and Bluechip's previous B+ rating for USDC was based on an old methodology, which cannot be directly used for technical comparison.

According to Slow Mist's warning, two attackers have been detected replicating the recent Notional Finance vulnerability attack method on the BSC chain. The attackers have completed their preliminary preparations and created malicious fCash positions using the same vulnerability pattern. Currently, the attack has not been fully executed, and the malicious positions are awaiting expiration.Once expired, the attackers may settle the positions and withdraw assets from the protocol. Slow Mist strongly recommends that affected projects take immediate mitigation measures to complete protection before the positions expire.

The decentralized lending protocol Pencil Finance has announced the completion of a $1 million student loan portfolio on-chain, including fundraising, lending, repayment records, and fund returns, constituting a complete financing and repayment cycle. Animoca Brands, Open Campus, and NewCampus provided funding for this portfolio in July 2025.The education financing company ErudiFi issued most of the funds through Southeast Asian student loans and tuition financing, covering markets such as Indonesia and the Philippines. The portfolio operates for 12 months, supporting over 6,600 students across 118 schools and universities, of which approximately 1,050 students received funding directly attributable to Pencil Finance. Investors are divided into priority and subordinate shares, with the former providing fixed returns and enjoying repayment priority, while the latter has variable returns and bears the first loss from defaults. Pencil Finance claims this is the first fully on-chain student loan cycle, but has not disclosed interest rates, investor yields, default situations, or blockchain transaction records.

DeFi researcher Ignas posted on the X platform, stating that in the AI era, the way to find Meme coins seems to have fundamentally changed little. Taking Grok as an example, when asked to recommend worthwhile Meme coins, it typically only provides token codes based on historical data such as views, trading volume, and the number of posts on the X platform.Real Meme coin trading still requires human judgment on whether a project has the potential to "break out," including market sentiment, community atmosphere, narrative appeal, and whether KOLs suddenly start promoting it. Compared to asking AI once a day what to buy, being continuously online 24/7 to capture changes in market sentiment still has greater advantages.However, Ignas pointed out that AI is fundamentally changing liquidity provision (LP) strategies. AI agents can automatically filter liquidity pools and analyze factors such as trading volume, transaction fees, fee trends, liquidity depth, and suitable price ranges. Currently, related strategies are still being refined, but a methodology has already been formed that can be continuously optimized and generate compounding effects. If trading Meme coins and being "online 24/7" does not suit you, then leveraging AI to learn and execute LP strategies might be a more easily mastered skill.

Stonk posted on platform X that it has completed a buyback of STONK tokens worth over 1 million dollars, while over 7.5 million dollars in rewards have now been distributed to StonkFun ecosystem holders. As of now, Stonk's fee revenue has reached approximately 1.87 million dollars. Stonk previously posted on platform X stating "Support Stonk Token," which was then retweeted by Solana co-founder Toly with the caption "What is Stonk Token?"According to GMGN data, the market capitalization of the STONK token on Solana briefly surpassed 100 million dollars before retreating, currently reported at 86.55 million dollars, with a 1-hour decline of 5.46%.

GMGN data shows that Basecat's market capitalization briefly surpassed 83 million dollars, setting a new historical high, with a 24-hour increase of about 38%, currently reported at 73.4 million dollars. Coinbase has previously launched BASECAT spot trading.

Vitalik posted on the X platform, stating that recent research on transaction formats has led to a clearer understanding of "actions" and "dependencies" in Ethereum transactions, both of which can be optimized separately; signatures, UTXO's Merkle proofs, and ZK-SNARK or STARK belong to dependencies, while the call to send ETH belongs to actions.Dependencies can be processed in parallel, with state-related dependencies handled by the memory pool, while pure dependencies can be processed once at the memory pool layer and may be replaced by STARK proofs, thereby reducing execution and data processing. Vitalik pointed out that Ethereum's current scaling strategy needs to clearly distinguish between dynamic flexibility and static analyzability, with the latter achieving lower Gas costs; based on transaction volume, over 90% of Ethereum activities do not require dynamic flexibility. The EIP-8141 transaction type is developing towards a universal and minimalist call list, with new state types, recursive STARK memory pools, and key-controlled nonces also belonging to this direction.
