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.

The decentralized trading protocol Uniswap has launched an ETH/USDC trading pool, which uses a separated fee mechanism for buying and selling, applying different fee standards for buy and sell transactions.This pool is implemented through the VolatilePair Hook, which will charge temporary fees on trades that reverse significant price fluctuations, aiming to retain more arbitrage value for liquidity providers.

According to The Defiant, trading firm DRW executed a total return swap with Marex on the Canton network through Derivnex, referencing the on-chain corporate bond benchmark from S&P Dow Jones Indices. S&P Dow Jones Indices announced this transaction with Kaiko on October 13.The swap was provided by Marex, with DRW as the counterparty, referencing the iBoxx USD Liquid Investment Grade Index, which tracks investment-grade corporate bonds that are dollar-denominated and have good liquidity. The swap provides both parties with exposure to the index without holding the underlying bonds. The transaction will synchronize events such as valuations during the contract's duration between both parties, and plans to migrate margin, collateral, and contract payments to the same infrastructure will be advanced in subsequent phases.Kaiko's tokens combine benchmark data with access permissions and usage rules, retaining the authorized control of S&P Dow Jones Indices, and distributing signed official index values for Derivnex to use for valuation. Derivnex expresses the transaction terms in the form of Canton smart contracts and introduces a universal domain model standard for derivatives trading. DRW founder and CEO Don Wilson stated that both parties can "work off the same record, thereby simplifying the process," and noted that once cash and collateral flows are integrated, more transactions are expected to achieve greater efficiency.

According to the City of London Police report, 25-year-old London man Ajay Shinjin (also known as AJ Marley Cruz) was sentenced to two and a half years in prison by the Inner London Crown Court for his involvement in a SIM swap fraud case. He pleaded guilty on September 28 to two charges of conspiracy to commit fraud by false representation and transferring criminal property. The case involved the theft of cryptocurrency worth nearly £200,000 (approximately $265,000).In early November 2021, British telecom operator BT discovered unauthorized activity in its systems, where customers' phone numbers were transferred to SIM cards controlled by criminals, who intercepted one-time verification codes sent by banks and cryptocurrency platforms. The police identified several suspects based on device data provided by BT, and Shinjin was linked to four of the devices. He profited over £44,000, which he used for a vacation in Dubai, a luxury apartment in Canary Wharf, and a gold-plated dental grill.Details of the case revealed that one victim lost approximately £40,000 in cryptocurrency on November 2, 2021, with about £27,000 flowing into Shinjin's personal crypto account; a second victim had approximately £17,000 entirely transferred to his wallet; he also assisted in stealing about £8,000 from a third victim's Coinbase account and around £130,000 from a fourth victim. Shinjin was first arrested at his residence in 2021 and was re-arrested at Heathrow Airport upon returning from Dubai in October 2023.

The cryptocurrency payment company Ripple has expanded into stablecoins, asset custody, and has entered the long-term leveraged exchange-traded fund (ETF) swap financing sector, which has been dominated by large banks, becoming an important participant. According to The Wall Street Journal, leveraged ETF managers achieve target returns through total return swaps and other derivatives, such as amplifying the daily fluctuations of a particular stock or index; banks or brokers sell related contracts and charge fees, then buy stocks or derivatives to hedge their own exposure.According to Morningstar Direct, there are 593 leveraged ETFs in the United States, managing over $256 billion in assets, of which 426 are single-stock leveraged funds, a category that received regulatory approval in 2022. Ripple entered swap financing after acquiring the prime broker Hidden Road, which caters to cryptocurrency hedge funds last year; this business is now called Ripple Prime, which is collaborating with multiple ETF providers and hopes to expand to include other investment managers, including hedge funds.On Tuesday, Ripple Prime announced it would provide prime brokerage, clearing, and financing services to the hedge fund Brevan Howard. Ripple Prime President Noel Kimmel stated that this is a growing and significant part of the company's business. The report cited an example where a fund paid Ripple at a rate of 4 percentage points above the overnight bank financing rate, which as of Tuesday was approximately equivalent to 8% of the fund's assets on an annualized basis; this cost is included in the net asset value of the leveraged fund, separate from the approximately 1% management fee.

According to CoinDesk, the U.S. Commodity Futures Trading Commission (CFTC) has submitted two rules for review to the Office of Management and Budget (OMB). One rule aims to include event contracts within the regulatory definition of swaps, while the other is a "temporary final rule" that seeks to exclude "casino-style gambling products" from the scope of swaps.These two rules were received by the OMB this week, with the document dated September 28. OMB review is typically the last step before rules are submitted for public comment, and the temporary final rule will take effect immediately while allowing for subsequent public input and revisions.This move comes as the CFTC engages in a tug-of-war with multiple states over the nature of prediction markets. Event contracts are typically binary yes-or-no bets on measurable outcomes such as sports events and elections. Last week, the U.S. Sixth Circuit Court of Appeals ruled that Kalshi's sports contracts do not fall under swaps and should be governed by state gambling regulations, while the Eighth Circuit Court of Appeals made a similar ruling; however, the Third Circuit Court of Appeals previously determined that the CFTC has jurisdiction over prediction markets, creating a legal divergence at the federal level. CFTC Chairman Mike Selig believes that the CFTC has exclusive jurisdiction over prediction markets.If event contracts are classified as swaps and not as gambling products, it could weaken the positions of various states in multiple lawsuits against prediction market platforms like Kalshi. The CFTC is legally required to consist of five commissioners, but President Trump has yet to nominate additional commissioners, leaving Selig as the sole commissioner, who is unilaterally advancing regulatory and policy decisions. Additionally, information disclosed by the OMB indicates that the CFTC recently submitted a "pre-rule" focusing on cryptocurrency regulation to the White House.
