The cross-border payment company Conduit has filed a lawsuit in the Southern District of New York Federal Court, accusing the stablecoin issuer Tether of freezing its $2.76 million in funds and refusing to unfreeze or provide any explanation. Conduit states that its USDT has been locked for over a year. The complaint claims, "Conduit owes no money to Tether and has no obligations to Tether."Conduit uses stablecoins, including Tether's USDT and Circle's USDC, to transfer funds across more than 100 countries. The lawsuit states that the wallet frozen by Tether is equivalent to Conduit's "operating bank account." This freeze reportedly stems from an investigation involving Conduit's former client Onix Intermediações, which was received by the Brazilian Federal Police. However, Conduit claims that law enforcement has confirmed it never requested the freezing of the payment service provider's funds wallet, and it is unclear why Tether took action; a Brazilian court also confirmed that Conduit is not under investigation related to the Onix Intermediações case.According to the complaint, Onix has not used the Conduit platform since April 2025, about a month before the creation of that funds wallet, and that wallet has never held any funds from Onix. Since the wallet is used to support company operations, Conduit states that its business has been affected, while Tether continues to earn interest on the reserves behind the frozen USDT.

According to The Block, Nasdaq-listed Solana Treasury company DeFi Development Corp. (DFDV) announced that it has approved an open-ended buyback plan to repurchase all outstanding shares of its CHAD preferred stock, including any shares that may be issued in the future.The plan gives the company flexibility to repurchase when the trading price of CHAD is below the $10 par value. The company stated that it does not intend to immediately buy back CHAD but hopes that the preferred stock will stabilize near the par value first.DeFi Development CEO Joseph Onorati stated that the company's primary goal is simple: to bring CHAD back to par value. He mentioned that this is not an announcement to buy CHAD today, but rather to set up the infrastructure, so that once CHAD stabilizes near par value, if it subsequently falls below par, the company will have an additional tool available. He also stated that the company views CHAD as a long-term financing platform rather than a one-time issuance.This open-ended authorization adds a potential funding allocation tool to DeFi Development's existing $300 million At-the-Market (ATM) issuance plan for CHAD, which the company previously stated would be used to raise funds for increasing its holdings of SOL. The company paid the first dividend on CHAD on October 1.Additionally, the company stated on Monday that preliminary estimates for the third quarter show that as its Solana Treasury increased to 2.56 million SOL over the past week, the net asset value per share has more than doubled compared to before. DFDV's stock price rose 3.3% during Tuesday's trading session.

Cryptocurrency trader Ansem posted that he believes correlating the current cycle with the markets of 2020, 2023, or 2024 has limited reference value.

New fields will bring new capital flows, products, and a large amount of speculative activity, which is the framework he uses to analyze this cycle.

Grayscale's parent company DCG stated on the X platform that last week the U.S. Securities and Exchange Commission (SEC) proposed reforms to the accredited investor system, allowing certain investors to qualify for participation in the private market through exams and other means. This initiative was suggested by DCG founder Barry Silbert as early as 15 years ago.It is reported that Barry Silbert raised the issue during the founding of SecondMarket around 2011, stating that the SEC's "accredited investor" system primarily relies on income and net asset standards, but wealth levels do not necessarily represent investment capability. Some high-net-worth individuals may not possess sufficient financial knowledge, while some ordinary investors should also have the opportunity to qualify for participation in the private market if they pass the financial literacy tests set by regulatory agencies.
