According to The Block, Nasdaq-listed Solana reserve company DeFi Development Corp. (DFDV) announced that it will raise the annual dividend yield of its CHAD preferred stock from 13% to 14%, effective November 2. Based on a par value of $10 per CHAD share, the annual dividend will increase from $1.3 per share to $1.4 per share, paid once every business day, contingent upon the company's board declaring the dividend. The company stated that future funds raised from CHAD issuance will be used to expand its Solana reserves, which generate income through staking and validating node operations.CEO Joseph Onorati stated that raising the dividend yield to 14% will help expand investor participation and grow the scale of CHAD. He noted that the appeal of CHAD lies in providing double-digit dividend income through Nasdaq-listed preferred securities, with daily payouts, while the issuer holds income-generating SOL reserves. The company aims to position CHAD as a leading digital credit tool, enhancing the ability to accumulate SOL, adding value for common stock shareholders, while maintaining prudent capital management.DeFi Development increased its holdings by approximately 22,070 SOL and equivalent assets last week, raising its total holdings to about 2.59 million SOL; the company stated that CHAD reached a new trading price high that week and recently approved a buyback plan to repurchase up to all issued CHAD shares.

According to The Defiant, the on-chain insurance protocol Firelight based on the Flare network announced on October 15 that its on-chain insurance has launched the Protected Strategies USDC vault for Kraken DeFi Earn, providing a collateral-backed compensation mechanism for specific protocol failures.The independent manager of the vault, Sentora, insures the vault rather than Kraken itself. Depositors do not need to actively choose to participate, but the insurance comes with conditions: Kraken discloses that the compensation limit for each deposit address during each insurance period is $100,000, and the total compensation amount is also constrained by the overall vault limit and available capital. Compensation is issued by Sentora in USDC to eligible wallets, and Kraken does not provide funds or guarantees.Firelight lists six types of failures that are eligible for compensation: smart contract vulnerabilities, oracle failures, governance attacks, and bad debts, depegging, or redemption failures caused by protocol mechanism failures. Insurance only applies to markets and positions recorded during the insurance period. Normal fluctuations, normal liquidations, depegging that operates as designed during redemption, and withdrawal delays caused by high organic utilization are excluded; insider theft, stolen private keys, phishing, and regulatory actions are also not covered.The trigger conditions for redemption failure are if the insured position cannot be withdrawn for more than 72 consecutive hours, or if the amount returned after deducting disclosed fees is less than 90% of fair value. Compensation does not require depositors to file claims themselves, as it is determined by a five-member risk committee through a three-fifths majority vote.On-chain records show that the insurance scale marked as "Kraken DeFi Protected" is $30.5 million.

According to The Defiant, Jupiter has launched a beta trading product called YOLO, which supports up to 1000 times leverage, and this product has not yet been audited.According to the official statement, users trade against the platform's capital pool (house) in this product.

The decentralized trading protocol Uniswap announced that the VolatilePair Hook has been launched on the Ethereum mainnet, with the first trading pair being ETH/USDC. This is a dynamic fee Hook for liquidity providers in Uniswap v4, where fees adjust according to market fluctuations.Uniswap stated that this year, the trading volume of volatile trading pairs on Uniswap exceeded $50 billion. Unlike stablecoin trading pairs, these assets do not have a fixed price, and liquidity providers under static fees will bear the price changes not covered by the fees. This Hook recalculates the buy and sell rates separately for each exchange based on recent price changes, maintaining competitive spreads.When the pool price rises, the buying cost is higher and the selling cost is lower; when the price falls, the direction of the fees is reversed. After significant price changes, trades that drive price retractions will pay temporary fees. Pool parameters and fee logic can be upgraded through Uniswap governance without the need to migrate liquidity pools. The StablePair Hook, launched in September, introduced dynamic fees for stablecoin trading pairs, achieving a trading volume of $3.1 billion within four weeks. The VolatilePair Hook is part of the Hooks launched by Uniswap Labs, along with StablePair, Permissioned Pools, and LitePSM.

X user Irene Patrikios (@crypto_irene) announced that she has been appointed as the Chief Business Officer of the fully homomorphic encryption company Zama. She stated that she has been working in the cryptocurrency industry for nearly 12 years and believes that blockchain requires institutions, enterprises, and individuals to publicly operate financial activities, a gap that has long existed and is difficult to support large-scale funds on-chain. She joined the company in November 2025, before the launch of the Zama mainnet, and stated that confidentiality is the infrastructure that enables institutions holding global capital to truly go on-chain, and Zama is providing this capability.Irene Patrikios also mentioned that over the past year, Zama's business team has reached collaborations with several major participants to launch confidential DeFi and establish a business pipeline.

According to a report by the Korean News Agency, the Commissioner of the National Tax Service of Korea, Lim Kwang-hyun, stated during a National Assembly Finance, Economy, and Planning Committee inspection that the National Tax Service is preparing to announce taxation standards for virtual assets in November.Lim Kwang-hyun pointed out that the taxation standards for transaction types such as airdrops, hard forks, staking, and decentralized finance (DeFi) focus more on the economic substance rather than the form of the transaction, with whether it is a transfer or a loan being the key determining factor. If airdrops and hard forks have the nature of a transfer or loan, they should be considered taxable objects, while some details regarding staking still need to be discussed with the Ministry of Economy and Finance.

According to official news, Starknet announced the launch of shadow accounts, allowing users to participate in public DeFi activities through an independent address controlled by themselves, while keeping the association between this address and the main wallet confidential.Shadow accounts are independent pseudonymous addresses on Starknet, with funds sourced from the user's protected STRK20 balance. The first integration will go live tomorrow. The balance, transaction records, and holdings in various applications of the shadow account will still be publicly visible on-chain, but STRK20 can protect the association information between the shadow account and the user's main wallet. This means that users do not need to hide their DeFi activities themselves, while also reducing the likelihood of external observers tracing related activities back to their main wallet.

Bitget's Head of Greater China, Xie Jiayin, shared his thoughts on attending Token2049 in Singapore on Twitter.First, users are becoming increasingly professional and are starting to redefine products. The demand for options, strategy squares, and other tools that enhance capital efficiency is being proposed by users. For institutions, the improvement in capital efficiency brought about by tokenization is a core demand.Second, the bubble is clearing, and projects are beginning to de-tokenize. They are no longer solely relying on issuing tokens for marketing but are instead creating real value through payment, asset management, and brokerage services.Third, the industry is welcoming a clear regulatory framework, which will inevitably bring short-term pain. In the long run, compliance and institutionalization will drive the industry to mature into a robust financial infrastructure.
