F2Pool co-founder Wang Chun withdrew 7,461 ETH, worth $17.27 million, from Binance and later deposited the funds into Spark, according to Ai Yi monitoring. The transaction reflects a shift of assets from a centralized exchange to a DeFi (blockchain-based financial services) protocol. Spark is commonly used for onchain lending and yield strategies, allowing users to put Ethereum to work rather than leave it idle on an exchange.
