Vlad Novakovskiy, CEO of Lighter, announced at Korea Blockchain Week (KBW) that the fixed income market, including bonds and interest rates, could be the next growth opportunity for DeFi. Lighter has already launched related products. In August, it launched the 'US10Y Perpetual Futures,' which tracks the US 10-year Treasury bond, supporting up to 20x leverage. Users can take positions on US interest rates and Treasury bond prices on the DeFi platform without a brokerage account.
