According to ChainCatcher, Bull Bitcoin has integrated Payjoin, saying it is the first Bitcoin exchange globally to offer the protocol for deposits and withdrawals. The exchange also introduced “default Payjoin” and “Payjoin transactions.” Bitcoin purchases and sales made through the built-in exchange in BULL Wallet will use Payjoin by default. The on-chain privacy protocol obscures transaction intent through off-chain coordination, without requiring changes to Bitcoin’s consensus rules. Bull Bitcoin said this can help wallet users consolidate UTXOs and reduce future miner fees. In December 2024, BULL Wallet became the first wallet globally to integrate Payjoin V2. Bull Bitcoin said its wallet and exchange software are free and open source.

Amundi, Europe’s largest fund manager by assets, has launched a tokenized share class of its STOXX Europe 600 equity index fund on Ethereum, expanding its blockchain-based investment offerings beyond money market funds. According to Cointelegraph, the share class was issued in collaboration with CACEIS, a European asset-servicing company that provided the tokenization infrastructure. Amundi said the fund will remain available through traditional investment channels. It tracks the STOXX Europe 600 Index, which includes 600 large-, mid- and small-cap companies across developed European markets. The asset manager also said it plans to develop a broader range of tokenized funds for institutional clients and digital platforms. Amundi cited potential benefits including improved accessibility, faster settlement and greater operational efficiency. The launch follows the company’s introduction of its first tokenized money market fund share class in November 2025, which was also developed with CACEIS on Ethereum. The launch comes as the global tokenized equities market grows, though its largest products remain concentrated in US-related assets. Tokenized stocks were valued at $4.24 billion as of Wednesday, Nov. 4, an increase of nearly 27% over the past 30 days, according to RWA.xyz data. The platform’s 10 largest tokenized equity products by value were all linked to US companies or US-listed securities, including Securitize, SpaceX, Circle and Alphabet. European financial firms have also urged regulators to speed up reforms. In April, a coalition of 39 companies and industry groups said the European Union risked falling behind the US in tokenized finance. The group called for broader asset eligibility, higher volume limits and the removal of time restrictions on licenses under the bloc’s Distributed Ledger Technology (DLT) Pilot Regime.

According to ChainCatcher, DeFi risk management firm Gauntlet closed the supply queues for its V1 vaults, paused asset allocations, and reduced exposure to LayerZero bridge assets after reports of an op-reth vulnerability on some OP Stack chains. Gauntlet said it was not aware of any reports that the vulnerability had been exploited. Closing the queues blocks new vault deposits but does not disable withdrawals or the underlying lending markets. Withdrawals remain subject to available liquidity in those markets. Gauntlet said the measures will stay in place until the issue is resolved, without providing a timeline for resuming operations. Gauntlet provides risk management for vaults on DeFi lending protocols, including Morpho, and sets collateral parameters, supply caps, and allocation strategies. The changes affect its V1 vaults operating on the relevant chains.

President Luiz Inácio Lula da Silva began discussions on economic policy for his next term with a group of left-leaning economists, including former Finance Minister Guido Mantega, Bloomberg reported. The choice risks deepening investor concerns about Lula’s approach to fiscal issues.

Hollywood studios and production companies are issuing policies barring employees from using insider information to bet on prediction markets. According to Odaily, the rules cover events such as company earnings, casting decisions and release dates, and prohibit employees from sharing information with family or friends to facilitate bets. At least one company has set up an anonymous hotline for reporting suspected betting by colleagues. Penske Media recently updated its employee handbook to prohibit bets on award nominations, casting decisions, production schedules and release dates. Columbia University law professor Joshua Mitts said trades on blockchain platforms may be difficult to trace when users conceal their identities through mixers. In February, Kalshi said a video editor at MrBeast’s company used confidential information to place bets and made about $5,000. The employee was fired and fined $20,000. U.S. prosecutors have also charged two people accused of using confidential information to bet on Polymarket; the cases are ongoing.
