Ted Livingston, founder of Kik, has launched a new stablecoin, USDF, on the Solana blockchain through his app Flipcash. The stablecoin is pegged 1:1 to the U.S. dollar and is fully backed by USDC, with Coinbase handling issuance, reserves, and compliance. USDF is designed for cash-like transactions within the Flipcash app, which allows users to create and trade community currencies with fixed supplies.
