Good Morning, Asia. Here's what's making news in the markets: Welcome to Asia Morning Briefing, a daily summary of top stories during U.S. hours and an overview of market moves and analysis. For a detailed overview of U.S. markets, see CoinDesk's Crypto Daybook Americas. Rest in Peace, Coinbase Wallet. No, the app itself isn't going away, but it is getting a new name. On its X profile , its name is crossed out and replaced with a 'TBA' and a few question marks. "There’s plenty of speculation about what it means, but I’m leaning toward 'The Base App.' That would fit the idea of Base unveiling a range of in-app experiences directly inside its wallet," Bradley Park, a Seoul-based analyst with DNTV Research, told CoinDesk in an interview. Base Creator Jesse Pollak was tapped to lead Coinbase's Wallet team last October , which lends credence to Park's theory. In an interview on the sidelines of Devcon in Bangkok last year, Pollak pla...

Embora os mercados tenham se estabilizado um pouco desde segunda-feira, o sentimento continua frágil em meio a uma nova rodada de tarifas emitidas por Donald Trump e outra semana de fluxos instáveis de ETFs. O BTC foi negociado perto de US$ 114.200 nas horas da tarde asiáticas de terça-feira, permanecendo estável no dia, mas ainda abaixo da faixa-chave de US$ 115.000 – US$ 118.000 que atuou como suporte de curto prazo nas últimas duas semanas.

Stablecoin Adoption Set to Surge After GENIUS Act, Hit $4T in Cross-Border Volume: EY Survey

Stablecoin adoption is gaining momentum among corporates and financial institutions driven by regulatory clarity and cost-savings in global money transfers, according to a survey by EY-Parthenon. Conducted with 350 executives in June after the Senate passed the GENIUS Act, the survey found that 13% of firms already use stablecoins, mainly for cross-border payments. Among those who didn't use stablecoins, 54% expected to adopt them within the next six to 12 months. Regulatory clarity provided by the GENIUS Act was widely viewed as a turning point. The legislation, which was signed into law in July, provided long-awaited rules for U.S. dollar-denominated stablecoins, including reserve requirements and issuer approval processes. Executives said in the survey the law reduces uncertainty around liquidity, tax treatment and custodial services. Cost savings are also a key driver for adoption, with 41% of current users reporting at least a 10% reduction in expenses from using stablec...
