Solana treasury company DeFi Development Corp (DFDV) has proposed a public offering of up to $20 million in Variable Rate Series C perpetual preferred stock, earmarking the proceeds for additional SOL purchases. The preferred shares carry a par value of $10 and a variable dividend with an initial annual rate of 13%; the first scheduled dividend date is Oct. 1, 2026. A 12-month dividend reserve fund will be established at closing and may be funded with cash, financial instruments or crypto assets. R.F. Lafferty & Co is the book-running manager. DFDV said the funds will be used for general corporate purposes, including buying more SOL and other crypto-related investments. The announcement follows a week in which DFDV resumed accumulation, paying an average $98.14 for about 19,000 SOL and lifting its holdings to around 2.33 million SOL. SOL was changing hands near $103. CEO Joseph Onorati said the company is built to provide leveraged exposure to Solana. The offering adds to a broader trend of listed SOL treasury firms including SOL Strategies, which is cleared for Nasdaq, and Classover, which previously announced a $500 million reserve build.

GTE has opened early registration for its MegaETH-based decentralized exchange, giving users points for reserving a username, following the project on X and Instagram, and downloading a card.

Crypto trader Rune said on X that he spent $1.8 million in an over-the-counter deal to buy a 37.4% stake in a Nasdaq-listed company, then laid out a plan to tokenize the stock on Robinhood Chain and pair it with a meme coin. The idea is to route meme coin trading activity into demand for the stock token, require 1:1 backing with real shares, and turn that into buying pressure in the underlying U.S. stock. Rune said the target company has a $4.8 million market cap, a $0.12 share price, $380,000 in annual recurring revenue, $6.2 million in debt, and a 92.3% short interest ratio. The proposal has drawn attention because it flips a capital-markets playbook seen in recent years. Instead of a public company raising money to buy crypto, Rune is describing a crypto-native community using token demand to buy into a public company. Still, major parts of the story remain unverified. X Community Notes said no Nasdaq-listed stock currently appears to match all three of the cited metrics at once: a $4.8 million valuation, a $0.12 share price, and 92.3% short interest. Rune has not disclosed the company name or an SEC filing number. Questions also remain around custody, reserve proof, liquidity, and regulation. The structure would require compliant custodians to hold real shares against token issuance, and the explicit goal of triggering a short squeeze through meme coin-driven buying pressure could invite scrutiny from the U.S. Securities and Exchange Commission.

A heavy news cycle from Aug. 31 to Sept. 1 brought fresh movement across exchanges, crypto treasuries, regulation, tokenization, AI products and on-chain markets. Binance said it will remove 12 cross and isolated margin pairs on Sept. 3 after suspending borrowing on some isolated pairs on Sept. 1, with auto-liquidation, order cancellation and delisting to follow. Strategy disclosed it bought 4,603 BTC for $369.7 million, while BitMine reported another week of ETH accumulation and later bought 51,000 more ETH from FalconX and BitGo. In Europe, the European Commission designated ChatGPT as a very large online search engine and classified Reddit and Roblox as very large online platforms under the Digital Services Act, triggering stricter compliance obligations. Elsewhere, ICE said it is working with tZERO on tokenized securities infrastructure, Telegram began rolling out Gram Wallet to a subset of users ahead of a wider launch to more than 1 billion users, and Solana posted record fee and governance participation data. The period also included large wallet transfers, SEC policy moves, Hyperliquid’s reported U.S. market discussions, AI-related fundraising and product launches, and a series of macro comments spanning bonds, gold and rate expectations.

South Korean crypto exchange Upbit said on Aug. 31 that it has temporarily suspended deposit and withdrawal services for assets running on the Ontology network while the network undergoes maintenance checks. The affected assets are Ontology (ONT), Ontology Gas (ONG) and MovieBloc (MBL). The suspension took effect from the time of the notice and will remain in place until Upbit confirms that deposits and withdrawals on the relevant network are safe to resume, with a separate notice to announce the restart time. Upbit said spot trading for the affected assets will continue as normal during the suspension. Still, user deposits, withdrawal address registration and refund processing for those assets have all been paused. The exchange also warned that deposits sent to Upbit during the suspension may fail to arrive properly and could, in some cases, become unrecoverable.

Ontology has halted block production on its mainnet after its core development team found a potential security risk during a routine security check, according to the project’s blog cited by ChainCatcher. The pause was described as a precautionary measure so the technical team and validators can conduct a full security review of the network and related components. The team said it has not confirmed any security incident and has seen no signs that user funds were lost or stolen. Based on the current assessment, ONT, ONG, and other on-chain assets have not been affected. Ontology also said the decision was not a response to confirmed asset losses or an active attack. During the review, block production will remain suspended and on-chain transactions cannot be processed. Users do not need to move their assets or take action with ONT, ONG, or other holdings on the chain, though the team advised avoiding time-sensitive transactions until the network is formally confirmed to be back online. Ontology added that the duration of the halt has not been determined and that it will prioritize a thorough review over speed before resuming block production.

Nvidia used this week’s Gamescom event in Cologne, Germany, to lay out new support for its upcoming RTX Spark platform, which the company said is scheduled to launch this fall. According to the announcement, the platform has backing from several game publishers, including Electronic Arts, Embark Studios and Ubisoft, and multiple AAA titles are set to arrive on it. Nvidia said RTX Spark will natively integrate Electronic Arts’ Javelin anti-cheat technology and support RTX features including DLSS 4.5. The company also outlined a broader set of gaming technology updates tied to the same announcement. Those include DLSS 4.5 ray reconstruction, which is already available, path tracing support for titles including CONTROL Resonant, and a plan to bring NVIDIA ACE technology to games including Aniimo in early 2027. The company described RTX Spark as a platform built for next-generation Windows PCs, combining personal AI agents, advanced content creation and high-performance gaming in a single environment.
