Tom Wan, the data director at Entropy Advisors, stated that the transaction fees for Robinhood Chain will be included in the third quarter financial report to be released tomorrow. He mentioned that the transaction fees for the first quarter of this chain amounted to 51.1 million USD, which is about half of Robinhood's second quarter cryptocurrency trading revenue, and he is paying attention to whether the company will describe this chain as infrastructure for other businesses or as an independent source of income.Tom Wan noted that the average daily transaction fees in October have dropped to about 52,000 USD, with the decline primarily due to pricing. The increase in fees in late August was attributed to gas congestion, with the average transaction fee rising from 0.002 USD to 0.298 USD, and weekly trading volume increasing by 7.5%. On September 1 and September 3, Robinhood raised the gas target from 18 million per second to 40 million, and gas prices have returned to the lower limit of 0.02 gwei.He also mentioned that by the end of the third quarter, USDG on Robinhood Chain was 693 million USD, compared to 101 million USD on July 1; estimating based on a roughly 3.5% share and an average scale of 427 million USD for the third quarter, the quarter's revenue was about 3.8 million USD, which annualizes to about 24 million USD based on the current scale of 674 million USD. There are 195,000 stock token holders, and last week the DEX trading volume was about 700 million USD. In the second quarter, the cryptocurrency trading volumes for Bitstamp and the Robinhood App were 22.1 billion USD and 18.3 billion USD, respectively, and he stated that there is currently no public data indicating how much of that is related to this chain.

Currently, Fomo's cross-chain trading volume is more than 10 times that of other trading applications.

According to a report by Politico, Joel Greenberg, a shareholder of Circle Internet Group and a former software engineer at the company, filed a lawsuit in a U.S. federal court on Thursday, accusing U.S. President Donald Trump and his family of benefiting from two transactions involving the United Arab Emirates through the cryptocurrency company World Liberty Financial (WLFI), allegedly violating the U.S. Constitution's Foreign Emoluments Clause. This clause restricts the president from accepting money or other benefits from foreign governments without congressional approval.The lawsuit states that the first transaction occurred before Trump's second term began, in which he sold 49% of WLFI for $500 million, with the related funds reportedly coming from the UAE. After Trump took office, he reportedly earned millions from this transaction. The second transaction involved an investment fund established by the UAE government purchasing $2 billion worth of digital currency from the Trump family. The plaintiff alleges that this transaction inflated the value of the cryptocurrency assets held by Trump and generated millions in interest income for him, while significantly expanding the circulation of his stablecoin.

According to CoinDesk, Ben Edgington, the coordinator of the Ethereum rapid finality research direction, along with several researchers, submitted a draft proposing to reduce the transaction finality waiting time from about 16 minutes to about 4 minutes, improving it by approximately four times.The current goal is to push this draft into the formal upgrade proposal process. The core idea of the draft is to separate the original "block selection" and "finality confirmation" mechanisms of validators, allowing finality to progress at a faster pace and facilitating future adoption of quantum-resistant signatures.Faster finality is expected to reduce the costs incurred by cross-chain transfer services due to capital occupation. The Ethereum Foundation's research provides an example: if a service advances about 1 million dollars per hour, under a 16-minute delay, approximately 267,000 dollars would be pending recovery, which could be reduced to about 67,000 dollars after shortening to 4 minutes.

The Reserve Bank of Australia (RBA) stated in the frequently asked questions document regarding retail payment regulation conclusions that the removal of surcharges for the designated card networks eftpos, Mastercard, and Visa starting from October 1, 2026, is in the public interest. The RBA will lift the ban on the "no surcharge" rule for the aforementioned networks from that date, with the changes based on Standard No. 3 of 2016 and the revisions to the merchant card payment costs and surcharge standards in 2026. eftpos, Mastercard, and Visa have all decided to implement the no surcharge rule from that date, generally applicable to their credit, debit, and prepaid cards, including cards issued overseas.American Express, UnionPay, and PayPal have also decided to eliminate surcharges, but are currently not formally regulated by the RBA. American Express and UnionPay will withdraw from their existing commitments with the RBA on October 1, 2026, while PayPal's no surcharge rule will take effect on October 5, 2026. This scope is limited to fees charged due to customer card payments and does not include surcharges for weekends, public holidays, booking fees, or service fees. Merchants must comply with the new card organization rules unless exceptions apply; businesses, non-profit organizations, and inter-business card payments do not receive a general exemption.The reforms will be implemented in phases. Starting from October 1, 2026, a lower interchange fee cap will apply to domestic card transactions; from October 30, designated card networks and large acquirers must publish the specified card payment fee information on their websites. From January 30, 2027, large acquirers must disclose how the decrease in interchange fees is passed on to merchant service fees; starting April 1, the interchange fee cap will apply to transactions involving overseas-issued cards acquired in Australia, and acquirers must also provide merchants with more detailed statements. The RBA stated that businesses can still factor the costs of accepting card payments into their overall pricing and may offer discounts for specific payment methods.
