ChainCatcher News, according to Golden Ten Data, Investec Chief Economist Philip Shaw stated that there were strong overnight rumors that Walsh would take over, and related transactions were basically completed last night. Next, Walsh's stance on key issues such as interest rates and the balance sheet will be assessed. He pointed out that the U.S. fiscal situation is on an unsustainable path, and Walsh's appointment does not mean that Trump will not intervene in the Federal Reserve or other areas of government operations. Although the risk of a weaker dollar has decreased after today's announcement, risks still remain.

According to ChainCatcher, citing Golden Ten Data, Danske Bank analyst Kirstine Kundby-Nielsen stated that Waller's nomination is positive for the US dollar, as he is an experienced Federal Reserve official. If the final candidate were a more politically oriented or clearly dovish Fed chair, market tensions could intensify, whereas Waller's nomination has to some extent alleviated these concerns and eliminated some risks.

Stellar Protocol v25 is available on Pi Network mainnet and has brought a new X-Ray privacy system and support for ZK proof. Pi Browser v1.15.0 is being released in stages, and App Studio allows builders to access no-code Test Pi payments and ad-supported deployment. Pi Network has activated the Stellar Protocol v25 upgrade on its mainnet, adding an updated X-Ray privacy system and broader compatibility with zero-knowledge proof workflows. The network also began distributing Pi Browser version 1.15.0, an update intended to align software with the new protocol changes while supporting access to in-network tools. Pi Network reported the rollout targets about 15.8 million mainnet users. 🚨Pi Browser update is being rolled out.Some early adopters can now update to version 1.15.0.📱Please ensure your app is updated to the latest version.The Pi ecosystem is quietly entering a crucial phase.Those who are prepared will eventually understand. ⏳#PiNetwork #PiBrowser… pic.twitter.com/LWkp9l3LjS — PiNetwork DEX⚡️阿龙 (@fen_leng) January 30, 2026 The protocol update is an infrastructure change for applications that rely on privacy-preserving verification. Stellar v25 introduces improvements that target more efficient proving processes and lower execution costs for proof-based smart contract activity, to make it easier to run private app features on the network. The change will broaden support for proof systems used by privacy-focused applications. Pi Browser v1.15.0 is rolling out in stages, with early access available to some users before a wider release. The browser acts as the access point for Pi apps and related builder tools.  CNF recently reported that Pi Network launched a free Product Design Workshop that teaches UX and UI planning, prototyping, testing, and launch preparation for building Pi Apps. The program links with tools such as Pi App Studio and is designed to help non-coders turn ideas into functional apps within the Pi ecosystem. Pi Network App Studio Adds Payment Tools for Builders Pi App Studio has added a guided option for integrating payments without requiring code, using Test Pi as the initial payment rail. The feature is part of App Studio workflows designed for non-technical creators, where payment steps are handled through interactive prompts inside the Pi Browser interface. The current version supports Test Pi payment interactions that apply within a single active session, such as purchasing items or unlocking features during a defined activity in an app. Also, the update introduces ad-supported deployment for App Studio iterations, enabling users to deploy versions without paying Pi when their App Studio balance drops below a stated threshold. Pi Network said the approach is meant to expand access for users who have not yet migrated to the mainnet and therefore cannot spend Pi for app generation and deployment. The network said the ad option is a subsidy mechanism rather than a full cost recovery model, with ad revenue described as insufficient to match underlying deployment costs such as API and server expenses. The company also noted that the feature may change or be discontinued depending on economic sustainability. As CNF reported, Pi Network added a virtual USDT balance to the testnet, allowing users to test sending and receiving tokens. At the time of writing, Pi token was trading at $0.1651 , down 0.68% over the past 24 hours. Pi’s market cap stood at $1.41 billion, while 24-hour trading volume was $19.22 million.
