USDF, a new custom stablecoin, has been launched on the Solana blockchain through a collaboration between Coinbase and Flipcash. This initiative is part of Coinbase's "Custom Stablecoins" program, which allows businesses and protocols to issue their own branded USD stablecoins. USDF utilizes Coinbase's infrastructure for issuance, compliance, and settlement, aiming to facilitate payments, payroll, and cross-border transactions while ensuring regulatory compliance.
