Decentralized exchange Aerodrome Finance (AERO) and Velodrome announced their official merger, launching the on-chain spot exchange Aero, deployed on seven networks: Ethereum mainnet, Base, Robinhood Chain, Ink, OP Mainnet, Arc, and Arbitrum, aiming to integrate the existing businesses of the two DEXs into a unified platform. The exchange is developed by Dromos Labs.According to a statement released on Wednesday, Aerodrome accounted for 58% of DEX trading volume on Base in the third quarter, while Velodrome accounted for 60% on OP Mainnet, with Aerodrome leading all DEXs in Bitcoin-USD trading volume during the same period. The new exchange extends this model to seven networks, which collectively handle approximately $120 billion in DEX trading each month.

The French Ministry of Finance, the Financial Markets Authority (AMF), the French Central Bank, and the Prudential Supervision and Resolution Authority (ACPR) jointly proposed amendments to the EU's Markets in Crypto-Assets Regulation (MiCA), requiring cryptocurrency platforms to take responsibility for customer losses when they actively provide access to DeFi protocols without reviewing the protocols or ignoring known security risks.The French side proposed that platforms review relevant protocols before providing DeFi access and continuously monitor for vulnerabilities and suspicious activities, while also supporting the certification of protocols and smart contracts. These requirements will apply comprehensively to significant Crypto Asset Service Providers (CASP), with smaller platforms subject to proportionately adjusted obligations. France also proposed transferring the regulatory authority of significant CASPs from national regulators to the European Securities and Markets Authority (ESMA) and lowering the current EU daily active user threshold of 15 million. Additionally, France suggested re-examining the category of Asset-Referenced Tokens (ART) and adjusting the Electronic Money Token (EMT) framework to cover multi-currency stablecoins.

Bitcoin News posted on platform X, stating that as the Clarity Act is stalled, regulators are independently formulating rules for the digital asset market based on existing authorities. The Commodity Futures Trading Commission has solicited opinions on a framework for retail digital asset trading, which includes a new category of "crypto asset market" exchanges, with the comment period ending on December 14.The comment period for the Securities and Exchange Commission's proposed Regulation Crypto Assets will close on October 20. The pace at which regulators are crafting rules is faster than congressional legislation, but the relevant rules may face challenges in court or be rescinded by future commissions; a lasting regulatory framework still requires legislation.

The Liquid Network officially announced the progress of the phased recovery, stating that the network recovery work has entered the final stage, focusing on strengthening security mechanisms, conducting independent audits, and gradually restoring the redeeming function of pegged assets.In terms of functional recovery, the network will first gradually open semi-automated BTC and LBTC exchange services, coordinating with participating exchange service providers to implement this service, which itself does not impose transaction volume limits at the protocol layer.In the next phase, the Liquid Network will restore the 1:1 Bitcoin reserve support for the network, and then gradually reopen the Federation redeeming function to authorized PAK key holders, but the full restoration of related functions still depends on the completion of remaining security checks and operational requirements.

According to CoinDesk, France has narrowly passed a cryptocurrency tax amendment, proposing to impose a 31.4% capital gains tax on transactions exchanging crypto assets for stablecoins starting from January 2027.However, the amendment still needs to be approved by the French Senate and go through the budget coordination process before it can officially become law.

Further analysis reveals that the activities of whales (large holders) are weakening. The 90-day moving average of whale outflows for XRP has dropped to $4.97 million, the lowest level since October 2021. CryptoQuant believes that this lack of whale interest may indicate that large investors are waiting for more advantageous buying prices, thus delaying the increase of their market exposure. From a long-term perspective, this suggests that XRP may lack buying support in the absence of whale backing.In a broader market context, the investor group for Bitcoin (BTC) also showed signs of retreat in October. According to a report by Glassnode, Bitcoin's realized profit-loss ratio fell from 0.8 to 0.4, a decrease of 50%. This change indicates that market participants are shifting from aggressive trading to a more stable sentiment, reducing profit-taking activities and reflecting a shift in market sentiment.

According to a report by the Korean News Agency, the South Korean Ministry of Finance and Economy has convened a seminar on virtual asset taxation with five exchange operators: Dunamu, Bithumb, DigitalX, Coinone, and Streami, as well as institutions like the Financial Services Commission, to discuss current taxation regulations, market environment, tax preparation work, and the possibility of delaying or abolishing the tax, but no clear decisions have been made regarding related measures.South Korea's virtual asset taxation policy was established in 2020, originally scheduled for implementation in 2022, but has since been postponed to 2023, 2025, and 2027.

On Friday, the French National Assembly passed Amendment I-3898 with 38 votes in favor, 37 against, and 25 abstentions, proposing to tax certain cryptocurrency exchanges for stablecoin transactions. If the relevant provisions are approved, they are expected to take effect from 2027. This measure will change the way capital gains tax on cryptocurrencies is calculated, meaning that when investors exchange Bitcoin or other cryptocurrencies for stablecoins, the related gains may trigger taxation even if they have not been converted into fiat currency.The French National Assembly is scheduled to vote on the first part of the "2027 Finance Bill" on Tuesday. A proposal to carry forward realized cryptocurrency losses for 10 years was rejected by the assembly on Friday with 18 votes in favor, 75 against, and 3 abstentions. French lawmakers are also reviewing two cryptocurrency tax proposals: I-CF1822 aims to expand the exit tax to unrealized gains, applicable to taxpayers whose total cryptocurrency portfolio value exceeds 800,000 euros and who move their residence out of France; I-2701 proposes to require the declaration of holdings from self-custody wallets, with a threshold of total value exceeding 100,000 euros for the relevant tax year. Both proposals are still under review as of Monday.

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.
