According to @1HowardWu, he announced joining the Global Dollar network, stated there are no other L1s besides his, and emphasized that privacy is inevitable (source: X post by @1HowardWu dated Sep 16, 2025). The post provides no integration scope, timeline, or additional partner details, so the only verifiable information is the claimed exclusive L1 participation and the privacy focus (source: X post by @1HowardWu dated Sep 16, 2025). For trading relevance, the exclusivity claim and privacy narrative can shape sentiment toward privacy-focused L1 ecosystems once official integration details are published, so monitoring subsequent official updates is critical (source: X post by @1HowardWu dated Sep 16, 2025).
