Pump.fun, a Solana-based memecoin launchpad, has launched a mobile app for iOS and Android devices, enhancing accessibility for users to buy, sell, and create tokens for free. The app allows users to manage their digital portfolios and track assets in real-time. This launch coincides with a renewed frenzy in the memecoin market, spurred by a viral social media post from former Binance CEO Changpeng Zhao about his dog named Broccoli, leading to the creation of numerous Broccoli-themed tokens. Many of these tokens, particularly on Pump.fun and BNB Smart Chain's Four.Meme, experienced rapid price surges followed by crashes. Despite generating significant transaction volumes with a daily fee revenue of $15.5 million in its first year, the platform faces regulatory challenges, including a warning from the UK's Financial Conduct Authority and legal actions in the US over alleged securities law violations and intellectual property issues.
