[DeFi Protocol Spark Halts App Launch Plans, Shifts Focus to Institutional Liquidity] According to CoinDesk, DeFi giant Spark has decided to suspend its development plans for a crypto mobile application and instead focus on DeFi-native liquidity infrastructure and institutional trading, such as its recent $1 billion investment in PayPal's stablecoin PYUSD. Phoenix Labs CEO, the developer behind Spark, stated that given the intense market competition, the company will concentrate on its strengths and avoid blindly expanding into the retail sector. Spark's current TVL exceeds $9 billion, and the app plans may still be resumed in the future.
