[GasFree Officially Supports USDD for Transaction Fees, Expanding On-Chain Application Scenarios for USDD] According to Deep Tide TechFlow news on August 18, GasFree has officially integrated USDD as a payment method for on-chain transaction fees (Gas Fees). Starting today, users initiating USDD transfers via GasFree no longer need to hold TRX, energy, or bandwidth in advance. The system will automatically deduct fees in USDD, enabling a streamlined process of 'one balance for both transfers and payments.' This upgrade effectively lowers the usage threshold for USDD, addressing pain points in traditional on-chain transfers such as the complexity of preparing Gas and transaction failures due to insufficient balances. It significantly enhances transaction convenience and success rates. Additionally, this integration further broadens the practical applications of USDD in the on-chain payment sector, providing a more user-friendly and efficient solution for the widespread adoption of stablecoins in everyday transfers and circulation.
