The statement is unequivocally confirmed by multiple primary and secondary sources. Grayscale's official website, press releases, and social media (Sources 1, 8, 12) directly announce the launch of the 'Grayscale Ethereum Covered Call ETF' (ticker: ETCO). Reputable financial news outlets like CoinDesk and Blockworks (Sources 2, 14) corroborate the launch. The evidence consistently states the ETF's purpose is to generate income (Sources 11, 12, 14) through a covered call strategy, which involves selling options for premiums—a practice inherently linked to the volatility of the underlying asset.
